ABSTRACT

Naucorids are predaceous aquatic insects and the principal arthropod predators of biting

fly larvae. Naucorids exert natural control of mosquito larvae and are important with

respect to malaria in Tanzania. However, naucorids have been documented to harbor the

mycobacterium responsible for Buruli ulcer in Africa, although transmission is not

known. Therefore, to provide a sound foundation for future biological, ecological, and

epidemiological investigations, a study to document the taxonomic composition and

distribution of the species of Naucoridae of Tanzania was conducted from 2010 to 2012;

a total of 127 localities sampled. Habitats sampled included streams, rivers, waterfalls,

ponds, lakes, reservoirs, swamps, and cold and hot springs. Previously, only four genera

and seven species were known from Tanzania. All taxa previously recorded from

Tanzania were re-collected except two species (Neomacrocoris karimii Poisson and N.

usambaricus Montandon). These collections added an additional two genera and eight

species, including two undescribed species of Neomacrocoris and one undescribed

species of Macrocoris. As a result, the known fauna of Naucoridae of Tanzania now

comprises 6 genera and 14 species. This study provides the first authoritative

identification resource to determine the entire fauna of Naucoridae of an African country

using modern techniques. Publication of this study can serve as a model for future

studies of this type in other countries in the African continent.

CHAPTER 1

INTRODUCTION

The natural world includes a myriad of life forms, many of which have direct

effect on mankind in various ways. Some species of plants, animals, and fungi are used

by humans for food, shelter, clothing, and energy; research is underway to assess the use

of algae for oil production (Amin 2009). Other species act as competitors with man for

the same resources. Still other species directly affect the health of humans by vectoring

disease agents. In the absence of mankind, these species interact with one another in a

more or less sustainable fashion. However, to proceed with human development in

relative ignorance of the biota inhabiting a region carries with it the potential loss of

useful taxa as well as the possible embellishment of those that might be detrimental. This

says nothing of the cascade of effects with the ensuing trophic imbalance. Inventories of

regional biota represent an important and frequently overlooked area of research because

many scientists and others are more interested in focusing on the taxa of obvious human

importance while ignoring those presumed to be inconsequential. However, those

species thought to be unimportant could have profound effects that might not be readily

apparent. As such, inventories are a necessary and important first step in understanding

the biota of a region. Several inventories concerning aquatic Heteroptera have been

conducted at high profile national parks and other areas in Africa, although many of these

studies are old, incomplete, and of dubious accuracy. The family Naucoridae has not

been inventoried in any region of Africa, except as a component of taxonomically

broader surveys of aquatic Heteroptera, and never in Tanzania.

2

Naucorids are of contrasting economic importance because they are both

beneficial and potentially harmful. Their beneficial aspect is in their feeding on the

larvae of noxious flies. They have been reported as effective predators of mosquito

larvae and pupae, including species of Anopheles (Wladimirow and Smirnov 1932),

which vector malaria in Africa, hence suggesting them as possible biological control

agents of malaria vectors. Conversely, they are considered to have potentially harmful

effects on human health as they have been documented to carry the mycobacterium

responsible for Buruli ulcer, a necrotizing “skin eating" disease (Merritt et al. 2010,

Ebong et al. 2012). In Africa, Buruli ulcer has received the greatest notoriety in the West

African countries of Ghana and Benin, although it occurs elsewhere with cases

documented in Kenya and Uganda, just north of the Tanzanian border (Walsh et al.

2009).

Saucer bugs belong to family Naucoridae (Heteroptera) and are readily

distinguished from other insects by the shape of the body; Naucorids are dorsoventrally

flattened, ovate, and have retentorial prothoracic legs and natatorial meso- and

metathoracic legs (Sites 2000). Naucorids range in length from 0.4 to 1.9 cm. Other

distinctive features are that the membrane of the hemelytra is without veins and the

abdomen does not have terminal filaments. In most heteropterans, the membrane

contains veins, of which the number and arrangement serve to distinguish some families.

Naucorids pass all their life stages underwater and are predaceous, feeding on other

animals that they can overpower. Most species of Naucoridae inhabit the tropics

although a few are in temperate regions. They are predominant members of

macroinvertebrate communities in tropical streams and are believed to greatly influence

3

the biota of the streams. However, the ecological parameters associated with these

insects are not well known (Sites 2000). Little is known about the naucorid fauna of

Tanzania other than scattered distribution records (e.g., Poisson 1949). This study

explored the species of Naucoridae and their distribution throughout the country

including in Lake Tanganyika, which forms the western border.

The goal of this study was to conduct a faunistic survey of the species of Naucoridae of

Tanzania, identify the extant species, and document their distribution.

The specific objectives were:

i. To determine the species composition of the naucorid fauna of Tanzania.

ii. To document the distribution of each species of naucorid in Tanzania.

iii. To prepare a taxonomic key for the identification of the naucorids Of Tanzania.

CHAPTER 2

LITERATURE REVIEW

General history of research on Hemiptera and aquatic insects in Africa

Our knowledge of the Hemiptera fauna of Africa, especially south of the Sahara, is

poorly known (Linnavuori 1971). The extensive works on African Hemiptera are those

of the 19th

and 20th

centuries by Stål: Hemiptera Africana (1864-1865) and Enumeratio

Hemipterorum (1870-1876) (Linnavuori 1971). So far, the best researched region in

tropical Africa is Congo whose fauna was treated extensively by Schouteden in his

numerous publications (Linnavuori 1971). In addition to Schouteden, Villiers studied the

Reduviidae of the former French colonies in Africa culminating with Hemipteres

Reduviides de l’ Afrique Noire in 1948. Mancini published several works on the fauna of

Ethiopia and other Italian colonies. In 1967, Villiers again revised the Reduviidae of

Africa in his paper Revision des Reduviidae Africains. Only scattered papers have been

published from East Africa (Linnavuori 1971) including Hynes (1955) notes on East

African aquatic Heteroptera, although this suggests that there is much to be done,

including in Tanzania. The South African fauna has been treated in various older papers

on individual taxa [e.g., Notonectidae and Corixidae (Hutchinson 1929)] as well as in the

contemporary South African Animal Life series, which includes the Field Guide to

Insects of South Africa (Picker et al., 2002).

Overview of ecology of Naucoridae

Naucorids are contrastingly both beneficial and potentially harmful. Their beneficial

5

aspect is in their feeding on the larvae of noxious flies. Naucorids are predaceous and

pass all their life stages underwater feeding on other animals that they can overpower.

They are predominant members of macroinvertebrate communities in tropical streams

and are believed to influence greatly the biota of the streams. However, the ecological

parameters associated with these insects are not well known (Sites 2000).

Naucorids have been reported as effective predators of larvae and pupae of mosquitoes,

including species of Anopheles (Wladimirow and Smirnov 1932), which vector malaria.

Conversely, they have potentially harmful effects on human health in that they have been

documented to carry in their salivary glands the mycobacterium responsible for Buruli

ulcer, a necrotizing “skin eating" disease (Merritt et al. 2010). In Africa, Buruli ulcer has

received the greatest notoriety in the West African countries of Ghana and Benin,

although it occurs elsewhere in Africa with cases documented in Kenya and Uganda, just

north of the Tanzanian border (Walsh et al. 2009). After tuberculosis, Buruli ulcer is

emerging as the second most frequently diagnosed mycobacterial disease in humans, and

it remains a neglected disease even though it has been reported recently in some

developed countries (Merritt et al. 2010). By 2010, more than 32 countries had reported

Buruli ulcer cases, most of which were in West Africa, Southeast Asia, Central and South

America, the western Pacific, Australia, and China. The disease manifests itself as large

skin lesions that result in scarring and deformities. When severe infections are sustained,

amputations and disabilities commonly result. The disease is most frequently reported in

children from 4 to 15 years old, especially in Africa (Merritt et al. 2010). Mycobacterium

ulcerans is more frequent in communities in the vicinity of rivers, swamps and wetlands.

The disease is thought to be associated with anthropogenic changes in the aquatic

6

environment, such as a result of environmental disturbance including deforestation, dam

construction, and agriculture. This is considered a ‘‘mysterious disease’’, with its mode

of transmission unclear (Merritt et al. 2010), although bites from aquatic Heteroptera,

including Naucoridae, have been suggested as the mode of transmission (Ebong et al.

2012).

Overview of taxonomy of Naucoridae

The current taxonomic arrangement of 5 subfamilies with 37 genera and 378 species is

the result of periodic additions of genera to a long-standing set of subfamilies. As many

as 7 subfamilies have been recognized, although 2 of these recently have been elevated to

family level (Aphelocheiridae and Potamocoridae). The classification of the family as of

1971 was presented as a catalog and was updated twice in subsequent years (La Rivers

1971, 1974, 1976). Štys and Jansson (1988) later provided information and clarification

regarding the status of subfamily, tribe and generic taxonomy.

Research on Naucoridae in Africa

The naucorid fauna in Africa presently is known to include 56 species in 8 genera and 2

subfamilies. Little is known about the naucorid fauna of Tanzania other than scattered

distribution records of only 7 species in 4 genera in both subfamilies (e.g., Signoret 1860;

Montandon 1897a, 1900, 1909, 1913a, b; Poisson 1949, 1963). Thus, the literature from

which one can begin to understand the naucorid fauna in Tanzania is old and cursory at

best.

General topography, hydrology, and climate in Africa

The continent of Africa comprises 62 political territories with a total area of more than 30

million km2. The Mediterranean Sea separates Africa from Europe and the Red Sea

separates much of Africa from Asia. High southern and eastern plateaus seldom fall

below 600 m and have a mean elevation of approximately 1,000 m. The largest of these

are the southern Great Karoo and Kalahari Desert. The South African plateau is

connected to East Africa by distinct topographic features including mountain ranges,

tablelands and depressions. The most striking features are two great lines of depression,

due largely to the subsidence of whole segments of the Earth's crust, the lowest parts of

which are occupied by vast lakes. Toward the south the two lines converge to one great

valley occupied by Lake Nyasa. The Great Rift Valley is occupied for more than half its

length by water: the Great Lakes of Tanganyika, Kivu, Edward and Albert. Within these

10

valleys are many volcanic peaks. The eastern depression is the East Africa Rift Valley

with much smaller lakes, many of them brackish and without outlet. East of this rift

valley are Mount Kilimanjaro (5,889m) and Mount Kenya (5,184 m).

The higher region of Africa is formed by the Ethiopian Highland, a mass of mountains

forming the largest continuous area of high elevation in the continent (Fobil et al. 2003)

with little of its surface below 1,500 m, whereas the summits reach heights of 4,600 to

4,900 m. This area includes the Ethiopian Rift Valley and lies northeast of the East

African Rift Valley, the northern continuation of which extends to the Red Sea. There

are three main rivers in Africa: River Nile, the longest river on the continent; River

Congo, the highest water discharge on the continent; and River Niger, which flows out

almost a half of its length through arid areas. The largest lakes are Lake Victoria and

Lake Chad in the center of the continent; Lake Tanganyika between the Democratic

Republic of Congo, Burundi, Tanzania and Zambia; and Lake Malawi stretching along

the eastern border of Malawi. Numerous dams are situated throughout the continent,

including Kariba in Zambia on Zambezi River, Asuan in Egypt on the River Nile, and

Akosombo, the biggest dam of the continent in Ghana on the Volta River (Fobil et al.

2003). Most of the continent is within the tropics and generally does not experience

excessive temperature variations. However, arid regions including the lower plains and

deserts experience greater temperature extremes; they can be much hotter and

occasionally the temperature in the Sahara Desert can fall to the freezing point. In the

extreme north and south the climate is warm temperate with the northern countries

generally hotter and drier than those in the south. The southern part of the continent is

narrower than the north and experiences a moderating influence of the surrounding

11

oceans. Within the equatorial zone, especially on the shores of the Gulf of Guinea and in

the upper Nile basin, the continent experiences intensified rainfall.

The African continent generally south of the Sahara is the Afrotropical biogeographic

realm, whereas northern Africa is part of the Palearctic biogeographic realm. Europe and

much of Asia compose the rest of the Palearctic realm. It is only the Cape of Africa in

South Africa which is placed in the Afrotemperate region (Morrone 2002).

Topography, hydrology, and climate in Tanzania

Tanzania is in the eastern part of Africa, bordering the Indian Ocean between Kenya and

Mozambique. It lies between 6o 00

’ and 35

o 00

’ E and has a total area of ca. 945,000

km2

with ca. 886,000 km2

of land and ca. 59,000 km2

of water bodies. The country has

two offshore main islands of Zanzibar (Unguja and Pemba) and has 3,402 km of borders

shared with eight countries: Burundi, 451 km; Kenya, 769 km; Malawi, 475 km;

Mozambique, 756 km; Rwanda, 217 km; Uganda, 396 km; Zambia, 338 km; and its

coastline is 1,424 km. The climate in Tanzania varies from tropical along the coast to

temperate in the highlands. The terrain is mainly plains along the coast and central

plateau and highlands in north and south. The elevation extremes are the Indian Ocean

and Mt. Kilimanjaro (5,895 m).

Land use is dominated by permanent pastures (40%) and forests and woodland (38%).

Only 3% of the land is arable, 1% is in permanent crops, and the remaining 18%

represents other uses (Tanzania Bureau of Statistics 1993). Lake Tanganyika, Lake

Victoria, Lake Nyasa (Lake Malawi), and rivers such as Ruvu, Rufiji, Pangani, Mto-wa-

12

mbu plus natural and man-made dams and reservoirs are the main sources of irrigation

and hydroelectric power.

CHAPTER 3

ANNOTATED LIST OF NAUCORIDAE

Introduction

The Hemiptera fauna of the world has been researched at different levels of thoroughness

in different regions. For example, the faunas of Australia and North America are well

documented. However, although the South African fauna has been treated (e.g., Picker et

al. 2002), our knowledge of the Hemiptera fauna of most of Africa, especially south of

the Sahara, is poorly known (Linnavuori, 1971). Much of the African continent is within

the Afrotropical biogeographic realm and harbors a great diversity of tropical biota, with

insects being the most diverse group. The Belgian Congo is the region of tropical Africa

whose fauna has been most researched with explorations, which is reflected in several

publications by various authors including Schouteden. Scattered minor papers have been

published concerning the East African fauna (Linnavuori, 1971), suggesting there is

much to be done in Africa, including in Tanzania. The naucorid fauna of Africa has not

been systematically treated. The most recent works on the naucorid fauna of Tanzania

date back to the colonial era and early 1960s when the Tanzanian mainland still was

referred to as Tanganyika and the two Islands of Zanzibar referred to as Unguja and

Pemba. Unguja and Pemba joined to form Zanzibar, which in 1963 united with

Tanganyika to form the United Republic of Tanzania. Thus, Tanganyika, Unguja and

Pemba are valid place names prior to 1964, whereas Tanzania and Zanzibar are valid

after 1964.

14

Materials and Methods

Extensive collecting was carried out in Tanzania for 25 consecutive days from 24 July to

17 August 2010, during which 121 sites were collected. Three additional sites: two in

Tanga Region on 28 December 2011 and one in Morogoro Region on 31 December 2011

were sampled; the same three sites were sampled again on 29 January and 1 February

2012 making a total of 127 collection sites in this study. Tanzania has been apportioned

into six land resource zones (Panagos et al. 2011) and the collections were conducted in

all six zones (Fig. 1). During all collections, naucorids were collected using aquatic D-

nets (1.1 x 1.1 mm mesh) to sweep through submerged vegetation along shorelines and

bank undercuts of various water bodies. Almost all accessible and safe water bodies

encountered in the collection route were sampled. Sampled water bodies include rivers,

streams, waterfalls, cold and hot springs, dams, reservoirs, lakes, ponds, marshes and

pools. The collection localities were identified by L-numbers from 1144 to 1267, 1322 to

1324, and 1332 to 1334 (see details of locality data in Appendix). Photographs of the

collection localities can be viewed in the Locality Image Database at the internet site of

the Enns Entomology Museum, University of Missouri. One collection site, L-1155, was

in Rwanda along the border with Tanzania, and another, L-1217, was a blacklight

sample; thus, data for those two collections are excluded here. At each site, net contents

were placed into a white plastic pan and all insects removed and placed into a jar

containing 95% ethyl alcohol. Alcohol was changed later in the day to compensate for

dilution. All samples were brought to the laboratory at the University of Missouri where

naucorids were separated from other insects. Male genitalia were extracted under the

microscope and placed into a genitalia vial containing glycerin.

The collecting route of travel in 2010 was mainly by road although air and water

transportation also were used. The collection trip started in Mwanza Region on 24 July

2010 and finished in Kusini Region in Zanzibar on 17 August 2010. In Mwanza Region,

collecting was conducted for two days on 24 and 25 July at 7 collection sites and in Mara

Region at 3 sites. On 26 and 27 July 2010, three sites sampled in Kagera Region and one

site in Esta Province in Rwanda, then moved to Kigoma Region where collecting was

conducted for 4 days from 27 to 30 July. Kigoma Region is bordered by Lake

Tanganyika. In Kigoma Region, a total of 26 collection sites including Lake Tanganyika

and streams in Gombe National Park were sampled. From 30 July to 3 August, collecting

was conducted in Rukwa Region and a total of 23 collection sites were sampled. Four

collecting sites were sampled in Mbeya Region on 3 and 4 August, and four sites in

Ruvuma Region on 5 August. Two collecting sites in Iringa Region were sampled on 6

August, and seven collection sites were sampled in Morogoro Region on 6 and 7 August.

In Dodoma Region, two sites were sampled on 8 August. Six collection sites were

sampled in Singida Region on 8 and 9 August. Four collection sites were sampled in

Manyara Region on 9 August. Six collection sites were sampled in Arusha Region on 10

and 11 August. Nine collection sites were sampled in Kilimanjaro Region from 11 to 13

August. Twelve collection sites were sampled in Tanga Region from 13 to 15 August;

two collection sites were sampled in Pwani Region on 16 August. On 17 August, the

team traveled by Sea Bus express boat to Zanzibar where four sites sampled in three

different regions as follows: One site in Mjinimagharibi Region, two sites in Kaskazini

Region and one site in Kusini Region.

Results

In this study, two subfamilies of Naucoridae were found: Laccocorinae and Naucorinae.

Collections of Laccocorinae comprised three genera: Aneurocoris, Ctenipocoris, and

17

Laccocoris and a total of 5 species. Collections of Naucorinae comprised three genera:

Macrocoris, Naucoris, and Neomacrocoris and a total of 7 species. Previously, the

available literature indicated that only 4 genera and 7 species were known from Tanzania.

All taxa previously recorded from Tanzania were re-collected during data collection, with

the exception of old records of two species from the Usambara Mountains. As a result of

this study, two more genera, Ctenipocoris and Naucoris, and 5 more species are added to

the naucorid fauna of Tanzania. Thus the known naucorid fauna now includes 6 genera

and 14 species. Two of the species added to the fauna were undescribed in the genus

Neomacrocoris with distributions that are quite different; Neomacrocoris vuga Sites was

collected in only one stream in the Usambara Mountains, whereas Neomacrocoris

bondelaufa Sites was collected throughout western Tanzania in the East African Rift

Valley, although one specimen from South Africa also was examined. In addition, one

undescribed species of Macrocoris was collected in Kagera Region.

In this chapter, a checklist and annotated list of species and subspecies of Naucoridae

collected during this study and known from the literature are presented.

Aneurocoris insolitus Montandon

(Fig. 4)

Aneurocoris insolitus Montandon 1897a: Ver. Zool. Bot. Gesel. Wein, 47: 437.

Discussion

The genus Aneurocoris includes two species endemic to Lake Tanganyika: Aneurocoris

insolitus Montandon and Aneurocoris marlieri Poisson. Label data of museum

specimens indicated that A. insolitus was collected from rocks in this lake but during this

collection it was not found among rocks. Irvine and Donohue (1999) indicated that this

species lives on the bottom and on rocks, especially in shallow water, and possibly

19

remains submerged throughout its life cycle. This study found the reported habitat

information to be inaccurate. Rather than living on or among rocks, this species was

associated consistently with root mats of reed grass (Phragmites mauritianus Kunth) in

the four sites where it was collected. Other sites with sand and rock substrates also were

sampled, but A. insolitus was not found. The species was collected from the two extreme

ends of the Tanzanian shoreline and one site in the middle. Polhemus & Polhemus

(2008) were in error in reporting that two endemic genera of Naucoridae are known from

Lake Tanganyika. Only one endemic genus (Aneurocoris) is known from this lake.

Poisson (1960c) provided data on A. insolitus and described a second species,

Aneurocoris marlieri, endemic to Lake Tanganyika from the northwestern shoreline in

the Democratic Republic of Congo.

Diagnosis

Aneurocoris insolitus can be distinguished from other species of Naucoridae in Tanzania

by the entirely coriaceous hemelytra which are devoid of veins and sutures. It is

relatively small for the family, measuring 6.0–7.4 mm.

Distribution

Aneurocoris insolitus is limited to Lake Tanganyika, from Kigoma to the southernmost

point in Tanzania. Streams and rivers which flow to the lake were not found to harbor

the species. Its distribution in the lake is not continuous, but apparently restricted to the

isolated patches of reed grass, Phragmites mauritianus, where the insects live among the

rhizomes and root mats. The type specimen was listed from Mpala, Tanzania, which is

not along the coastline of Lake Tanganyika. This is considered to be either a case of

20

mislabeling or perhaps another small village on the lakeshore by the same name existed

at that time.

Ctenipocoris africanus Poisson

(Fig. 5)

Ctenipocoris africana Poisson 1948: Rev. Zool. Bot. Afr., 41: 219–221.

Discussion

Ctenipocoris africanus is the only species of the genus known from Africa, but has not

been reported from Tanzania previously. This species was described from Ituri in the

Democratic Republic of Congo (Poisson 1948). La Rivers (1960) subsequently

redescribed it as Heleocoris faradjensis from Belgium Congo (=DRC), which later was

synonymized with C. africanus (Polhemus and Polhemus 2008). This species is not

common in collections but specimens from Uganda in the British Museum were

examined. Presented here is the first record of C. africanus from Tanzania.

21

Diagnosis

This moderately-sized species measures 8.3 by 5.5 mm and can be recognized by heavily

spined meso- and metatibiae and femora, and the profemora are relatively small. The

greatest width of the pronotum is approximately twice its length at the midline, whereas

Aneurocoris and species of Laccocoris are three times as wide as long. The prothoracic

tarsi have two segments in both sexes, whereas Aneurocoris and Laccocoris are sexually

dimorphic; the male has two tarsal segments and the female only one. It is 8–9 mm in

length.

Distribution

Ctenipocoris africanus is known only from Democratic Republic of Congo, Uganda, and

Tanzania.

22

Discussion

This species was transferred from the genus Naucoris to Laccocoris by Stål (1865). The

African species of Laccocoris have been apportioned into two groups by Poisson (1949):

the spurcus group and the limigenus group. Laccocoris limicola is in the spurcus group,

which is characterized as having slightly shortened membranes of the hemelytra and

subbrachypterous, brachypterous, or micropterous hindwings, and the posterolateral

angles of the pronotum are more or less acute and recurved caudad (Poisson 1949).

Linnavuori (1987) added that the membranes of the hemelytra are acuminate apically.

Diagnosis

Laccocoris limicola can be distinguished from its two known congeners in Tanzania by

the sharp posterolateral angles of the pronotum. The body length is 8.5–9.3 mm.

Distribution

Laccocoris limicola has been recorded from Gariep (Northern Cape Province) and

Limpopo, South Africa (Stål 1855). During these collections, the species was found in

Kagera and Kigoma regions of western Tanzania. In each of the collections, it was taken

syntopically with L. limigenus Stål in association with rocks and submerged vegetation in

moderate current.

Laccocoris aurivillii Montandon, 1897b: Ann. Soc. Entomol. Belg., 47: 50–52.

Discussion

Laccocoris limigenus is arguably the most widespread and common species of

Laccocoris in Africa. L. aurivillii Montandon was considered by Poisson (1949) to be a

race of L. limigenus, differing from the latter by having a larger body size and more

slender phallosoma. Because of high variability in both characters, Linnavuori (1987)

formally synonymized L. aurivillii with L. limigenus. Poisson (1949) placed L. limigenus

in the limigenus group, which is characterized as being macropterous with alary

dimorphism rare, and with the posterolateral angles of the pronotum rounded. Linnavuori

(1987) added that the membranes of the hemelytra are roundedly truncate. The species is

common in oligotrophic rivers with a sandy bottom (Linnavuori 1981) and has been

recorded in shallow pools in river sandbanks with dead leaves and detritus (Weir 1966).

The species was most frequently found in shallow streams with sandy or silty bottoms

and in association with vegetation. It was collected syntopically with L. limicola at L-

1158 and L-1165.

Diagnosis

Laccocoris limigenus is distinguished easily from known congeners in Tanzania by the

rounded posterolateral corners of the pronotum. Body length is variable and was reported

24

as 7.0–9.5 mm (Linnavuori 1987).

Distribution

This species occurs throughout Africa and is known specifically from Algeria, Ethiopia,

(Linnavuori 1971), Sudan (Linnavuori 1987), Chad, Nigeria (Linnavuori 1981) and Niger

(Poisson 1950), west to Benin (Poisson 1951, Linnavuori 1981) and Togo (Poisson

1951), south through Central African Republic (Linnavuori 1981), Kenya (Poisson 1963),

Democratic Republic of Congo (Poisson 1949, 1951, 1954; Linnavuori 1987), Tanzania

(Poisson 1960b, 1963), Zambia (Poisson 1963, Linnavuori 1987), Mozambique (Poisson

1934), and South Africa (Poisson 1963, Linnavuori 1987).

In Tanzania, it has been recorded from Arusha Region (as Maji ya Chai), Tanga

Region, and Usambara North (Poisson 1963). This species was found to be widespread

and collected from 21 localities in 10 regions: Dodoma, Iringa, Kagera, Kigoma,

Manyara, Morogoro, Mwanza, Rukwa, Singida and Tanga regions.

Laccocoris spurcus congoensis Poisson, 1949: Inst. Parcs Nat. Congo, 58: 67-69.

Discussion

Laccocoris spurcus is one of the largest species of Laccocoris in Africa. The nominate

subspecies is known from South Africa. Poisson (1949) described a subspecies from

Democratic Republic of Congo which is known to have wing polymorphism, with which

are associated differences in pronotum shape. Poisson (1949) reported that

approximately 90% of the individuals from Democratic Republic of Congo were

27

subbrachypterous or brachypterous and 10% macropterous. All specimens collected

from Tanzania were brachypterous.

Diagnosis

Laccocoris spurcus congoensis is distinguished easily from known congeners in Tanzania

by its large size (length > 10 mm). Brachypterous individuals have the posterolateral

corners of the pronotum narrowly rounded and slightly angled caudad, whereas

macropterous individuals have the posterolateral corners of the pronotum broadly

rounded, similar to those of L. limigenus. The two subspecies of L. spurcus can be

distinguished from each other by the shape of the labrum; it is broadly triangular in L.

spurcus congoensis and acutely triangular in the nominate subspecies (Linnavuori 1987),

and the posterior spacing of the eyes is slightly less in L. spurcus congoensis (Poisson

1949).

Distribution

L. spurcus congoensis is known from Democratic Republic of Congo, whereas the

nominate subspecies was known only from Cape Province in South Africa. In Tanzania,

L. s. congoensis was found in only one locality at high elevation at Mbeya Peak in Mbeya

Region.

Subfamily Naucorinae

Macrocoris flavicollis Signoret

(Fig. 17)

Macrocoris flavicollis Signoret 1860: Soc. Ent. France An., 8: 970.

Discussion

In his treatment on the Hemiptera fauna of Madagascar, Signoret (1860) established the

genus Macrocoris with M. flavicollis as the type species. Poisson (1949) described two

subspecies of M. flavicollis based on pronotum characteristics and body size. More

specifically, M. f. chariensis Poisson is known from only the Chari Basin of Chad and has

the pronotum clear yellow with few or no small black spots and is smaller in body size.

M. f. uelei Poisson has the pronotum with larger, confluent black spots and the anterior

black spots on the posterior lobe are larger than those of the nominate subspecies. This

subspecies was described from Uele in the Democratic Republic of Congo (Poisson

1949) and also is known from Chad (Bebedja), Ivory Coast, central Sudan, and was

found among Ceratophyllum and other vegetation and in a swimming pool (Linnavuori

1981). M. f. flavicollis is known from eastern Sudan south throughout most of Africa

south of the ranges of M. f. chariensis and M. f. uelei and was recorded from marginal

emergent vegetation in pans and a marsh as deep as 2.5 ft in Zimbabwe (Weir 1966).

Linnavuori (1981) reported that this subspecies occurs among vegetation in eutrophic

waters.

Of all naucorid species collected in Tanzania, M. flavicollis was the most

frequently encountered; collected at 34 of the 127 sites sampled during the entire study

29

period. The species was found in large and small lentic water bodies ranging from lakes

to roadside pools and with grasses, algae, lily pads, and usually heavily vegetated. This

species was also collected from vegetated margins of sandy and muddy, slow streams.

Water bodies with disturbances including grazing, irrigation or other human activities

tended to harbor fewer Macrocoris flavicollis.

Diagnosis

This species is variable in appearance, but fresh specimens have a distinctly green head,

pronotum, connexiva and legs, which fade to yellow in alcohol or exposure to light. The

pronotum has scattered large, black spots and sometimes small black punctures. At the

posterior margin of the head, M. flavicollis has a pair of median black spots which

sometimes are contiguous, comprising two vertices more or less elongated anteriorly.

However, the key by Poisson (1959) requires that M. flavicollis have the spots absent or

only faintly indicated. The connexiva are concolorous. Body length is 8.9–11.2 mm.

Distribution

In addition to Madagascar and Zanzibar, from which M. flavicollis was described

(Signoret 1860), this species has been recorded from Sudan (Linnavuori 1971, 1981) west

through Chad (Poisson 1949, Linnavuori 1981), Central African Republic, Nigeria

(Linnavuori 1981), Benin (Poisson 1951), and Ivory Coast (Linnavuori 1981), south

through Uganda, Kenya (Montandon 1914, Poisson 1967), Congo (Poisson 1967,

Linnavuori 1971), Tanzania (Poisson 1963), Rwanda (Poisson 1949), Democratic

Republic of Congo (Poisson 1949, 1963), and Mozambique (Montandon 1899).

30

The species is widely distributed in Tanzania and was collected in almost every

geological region and from greatly varied elevations (30 to 1795 m). Specifically, it was

collected from Kagera, Kigoma, Mara, Mbeya, Morogoro, Mwanza, Rukwa, Ruvuma,

and Tanga regions. Macrocoris flavicollis was not collected from the central part of

Tanzania (Dodoma and Singida regions) and the neighboring regions of Manyara, Arusha

and Kilimanjaro.

Macrocoris sp.

(Fig. 18)

Discussion

This genus is endemic to the African continent and is represented by 10 species, 3 of

which are endemic specifically to Madagascar. Macrocoris and its sister genus

Neomacrocoris, also endemic to Africa, are relatively dorsoventrally robust for the

family. Both genera occupy heavily vegetated margins of water bodies. As a generality,

Macrocoris tends to be found more in lentic water bodies, whereas Neomacrocoris tends

to occur in marginal vegetation of slow streams. Macrocoris can be distinguished from

Neomacrocoris by its wider head, negligible claval commissure, and well-developed

parameres of the male genitalia.

This appears to be an undescribed species of Macrocoris. Species in this genus are

distinguished based on characteristics of pronotum punctation and maculation, connexiva

coloration, and characters related to male genitalia and medial lobes of the 8th

abdominal

tergum. Because this species does not agree in these features with any described species

or subspecies, I consider it to be undescribed. The most recent treatment of this genus

(Poisson 1959) did not provide a rigorous assessment of interspecific distinctions.

Although Poisson described many species and subspecies of both Macrocoris and

Neomacrocoris, his work has been found to be unreliable. Thus, generic revision is

necessary and description of this new species should be included therein.

34

Diagnosis

The pronotum of this species is beset with dense dark punctation and the body is highly

convex dorsally. Body length is 10.0–10.9. Poisson (1959) presented a key to the

species and subspecies of Macrocoris, in which he separated the taxa into two groups

based on connexival color patterns. One group is concolorous and the other has the

posterolateral corners black or densely maculated. As such, this undetermined species

falls into the latter group, which includes M. convexus, M. nigropunctatus Montandon, M.

distinctus Bergroth, and M. transvaalensis Distant.

Distribution

This species was found in only one locality and was among marginal vegetation on a dam

in Kagera Region.

Naucoris obscuratus Montandon

(Fig. 6)

Naucoris obscuratus Montandon 1913b: Bull. Sect. Sci. Acad. Roum. 1: 221.

Discussion

This species is common in eutrophic rivers and normally is found among vegetation and

debris (Linnavuori, 1971) in rivers, lakes, and pools (Linnavuori, 1981). Naucoris

obscuratus is the only member of the genus Naucoris known from Tanzania. Even

35

though N. obscuratus has been recorded from throughout Africa, in this study it was

collected at only a few localities in Tanzania and most were from the northern part of the

country. Montandon (1913b) listed this species from six localities, including “Hego

Tanganika”, which Poisson (1967) repeated the Montandon localities and referred to the

Tanganyika record as “lac Tanganyika”. Because Lake Tanganyika borders four

countries, this record was not specific to a particular country. Thus, the collections

reported here represent the first record of N. obscuratus from Tanzania.

Diagnosis

Naucoris obscuratus can be distinguished from the other two genera of Naucorinae in

Tanzania by its shape and size. N. obscuratus is much flatter than the dorsally convex

Macrocoris and Neomacrocoris and body length is only 6.5 to 8.7 mm. Further, males

do not have tergites 7 and 8 modified, whereas those of the other genera have medial

lobes with modifications that are species specific. Males have parameres that are well

developed and overlapping, whereas Macrocoris has parameres that do not overlap and

Neomacrocoris lacks parameres.

Distribution

In the original description, Montandon (1913b) reported the distribution as from Sudan to

Lake Tanganyika, Egypt, Nigeria, and South Africa, and this was largely repeated by

Poisson (1967). The East African countries of Uganda and Kenya were added by

Montandon (1914) and Poisson (1963), respectively. Congo was added in the description

of the subspecies N. o. nanus (Poisson 1960a). West Africa was added (Linnavuori,

1971) and was followed by specific country records for Ivory Coast, Ghana, Nigeria, and

36

Chad (Linnavuori, 1981). During this study, N. obscuratus was found mostly in northern

Tanzania. More specifically, it was collected from seven localities in Kagera, Kigoma,

Kilimanjaro, Mara and Pwani regions.

Neomacrocoris bondelaufa Sites & Mbogho 2012: Zootaxa (in press).

37

Discussion

Neomacrocoris bondelaufa is a newly described species and was first found during these

collections. Although the species is distributed widely throughout the Rift Valley of

western Tanzania, its distinction from its congeners of the region apparently was

overlooked because of its superficial similarity. During this project, N. bondelaufa was

collected syntopically with N. handlirschi at L-1202 and with N. parviceps at L-1157,

1164, 1182, and 1202. All three species were collected together in the Msanzi River in

Rukwa Region (L-1202). The habitat in which these species occur is the densely

vegetated margin of streams where current is minimal. Typically, specimens were

collected in undercuts and dense vegetative cover with muddy substrate.

Diagnosis

N. bondelaufa is nearly indistinguishable superficially from several congeners, with

which it co-occurs, including N. parviceps and N. handlirschi, without examination of

male genitalia. However, fresh specimens of N. parviceps are reddish-orange on the

abdominal sterna, whereas N. bondelaufa and N. handlirschi are brown. N. handlirschi

generally is only slightly larger than N. bondelaufa, but the size ranges overlap. Until

other diagnostic characters are discovered, females must be associated with males for

identification using male genitalia. Specifically, the apex of the phallosoma has a strong

gibbosity to the right and ventrally in N. bondelaufa and directly to the right in N.

handlirschi, whereas it has an elongate flange to the right in N. parviceps. Further, the

left side of the shaft of the phallosoma beyond the gibbosity is arcuate and the left side of

the apex appears flattened in dorsal view in N. bondelaufa, whereas the shaft is straight

38

and the flattening is on the distal margin in N. handlirschi. The apical flattening appears

flattened on the left side in dorsal view in N. parviceps. Body length is 8.2–9.2 mm.

Distribution

This species is distributed widely throughout the Rift Valley of western Tanzania and

also occurs in South Africa.

40

Discussion

This species originally was described as Macrocoris handlirschi from southern South

Africa (Montandon 1909). Four years later, this and two other species of Macrocoris

were transferred to the new genus Neomacrocoris by Montandon (1913a). Montandon

(1909) described the species from a series but did not designate a type specimen. Sites

and Mbogho (2012) located a single syntype in the Naturhistoriches Museum in Vienna

and designated it as the lectotype. Poisson (1948) reported that the species has a wide

size range of 8.5–10 mm length and 5.2–5.3 mm width. N. handlirschi was distinguished

from N. angusticeps by Montandon (1914) by its smaller size; and the pronotum with

more distinct black punctation, posterolateral corners blunter and narrowly rounded, and

a superficial transverse furrow of the pronotal disc. Poisson (1948) also noted a slight

indication of a posterior transverse furrow of the pronotal disc.

The variety N. handlirschi var. armatus was described by Poisson (1948) from

seven localities in the Belgian Congo (Luebo, Matadi, Boma, Luluabourg, Mayidi, Haut

Uelé, and Katanga) and distinguished from the nominate form by the condition of the 7th

abdominal tergum. Specifically, the left lobe had 1–8 denticles in n. handlirschi armatus,

whereas it was without denticles in the nominate subspecies. In a population sampled

from a small stream in Gombe National Park in northwestern Tanzania were males with

from zero to five denticles on the left medial lobe of the 7th

abdominal tergum, thereby

presenting characteristics of both subspecies. Because both character states were present

in the same population, the subspecific designation based solely on presence or absence

of denticles is not valid; thus, Sites and Mbogho (2012) synonymized the subspecies.

41

Diagnosis

This species may be distinguished from all of its congeners except N. ndugai, known

from only Rwanda, by the slight flattening of the pronotum and by the presence of short,

thick setae sparsely distributed over the surface of the scutellum and hemelytra. In fresh

specimens, the short setae can be found sparsely over the entire dorsal surface of the

hemelytra, including the clavus and membrane; however, the hairs apparently are fragile

and less evident on older or mishandled specimens. The condition of the apex of the

phallosoma distinguishes N. handlirschi from N. ndugai. The female subgenital plate is

gently sinuate to the distal spatulate process, which differs from only N. vuga among the

known congeneric females from Tanzania. Body length is 8.6–9.2 mm.

Distribution

The species occurs from eastern Sudan (Linnavuori 1981) and the Democratic Republic

of Congo and Uganda south to South Africa. As such, N. handlirschi and N. parviceps

might have the widest distribution of any species of Neomacrocoris. In Tanzania, N.

handlirschi was reported from the Usambara Mountains in the northeastern part of the

country (Poisson 1963). N. handlirschi was collected syntopically with N. bondelaufa at

L-1202 and with N. parviceps at L-1174 and 1202. All three species were collected

together in the Msanzi River in Rukwa Region (L-1202). Specimens were collected in

densely vegetated stream margins with muddy or gravelly substrate.

Discussion

This species is known from only a single male specimen collected in a small

stream over rocks near the route of Muheza to Amani on the road to the Karimi Tea

Estate in the Usambara Mountains of Tanzania, as was given in the original description.

No other account of this species has been published besides its listing in the La Rivers

(1971) catalog and recent inclusion in the revision of the genus (Sites and Mbogho,

2012). During this study, this species was not collected despite collecting at the type

locality and in nearby streams. The substrate of the stream running through the tea

plantation is covered heavily with red silt resulting from the agricultural activities, and

very few insects were found overall. Elsewhere in the Usambara Mountains, a

superficially similar species (see N. vuga below) was collected, which I was able to

determine as distinct only after examination of the genitalia of N. karimii (Fig. 23). The

type specimen of N. karimii is card-mounted and housed in the Muséum National

d'Histoire Naturelle of Paris, but is missing the posterior abdominal segments. Two

microscope slides containing the aedeagus and 7th

and 8th

segments of this specimen are

43

housed in the Drake Collection in the U. S. National Museum (USNM). Poisson (1963)

illustrated the body, aedeagus, and 7th

and 8th

terga.

Diagnosis

This species is distinguished from its congeners in Tanzania by its ovate body (Fig. 12)

and the distinct male phallosoma (Fig. 23). Because this species is known from only the

holotype, the structure of the female subgenital plate is not known. Body length is 10.3

mm.

Distribution

This species is known from only a single male specimen collected from Tanga Region,

near the route of Muheza to Amani on the road to the Karimi Tea Estate in the Usambara

Mountains of Tanzania.

Discussion

This is arguably the most common species of Neomacrocoris in Africa. Poisson (1948)

considered Neomacrocoris parviceps to resemble N. handlirschi and N. nanus, and is

44

variable in pigmentation and size. It has been given as 7.8 (Montandon 1900) to 9 mm

(Poisson 1948) in length. The specimens from throughout Tanzania range from 7.36 to

8.56 mm. This species is variable in expression of pigmentation, size, as well as other

subtle differences in degree of angle and spination of abdominal tergal lobes and

curvature in the structure of the phallosoma. Poisson (1948) described a variety (N.

parviceps var. ocellatus) based on more pronounced punctation near the margins of the

pronotum and a more clear (“nette”) claval commissure than that of N. p. parviceps, but

gave no distribution information. Although he treated it as a variety, Poisson referred to

the alternate condition as N. parviceps parviceps, implicitly conferring subspecific rank

to ocellatus. In later papers, he referred to it more formally as a subspecies (N. p.

ocellatus) (Poisson 1949) and reported it from Maua, Kilimanjaro Region, Tanganyika

(Poisson 1963). Despite collecting throughout the area of Maua, no naucorid specimens

were found.

Diagnosis

This is a moderately sized species with an obviously reddish-orange abdominal sternum

in living specimens. Thick setae on the hemelytra are restricted to the embolium and

adjacent corium. The longitudinal flange and apex of the phallosoma readily distinguish

this species. The female subgenital plate is gently sinuate to the distal spatulate process.

Body length is 7.36–8.56 mm.

Distribution

The type locality is Dar Es Salaam, Tanzania and the lectotype is housed in the

Hungarian Natural History Museum - Budapest. This species is known from Sudan

45

(Linnavuori 1981) and was considered to be widespread in East Africa (Poisson 1948).

This species also has been recorded from Ghana, Ivory Coast, Upper Volta, Democratic

Republic of Congo, Uganda, and South Africa (Sites and Mbogho, 2012). This species

was collected from throughout Tanzania, including the island of Zanzibar.

47

Discussion

This is the type species of the genus as designated by Štys and Jansson (1988). The type

specimen was collected in the western Usambara Mountains of Tanzania. Although the

holotype has been lost since the 1930s, a neotype from the Democratic Republic of

Congo was designated by Sites and Mbogho (2012). Despite collecting several streams

in that area, nothing resembling the neotype was found.

Diagnosis

Although it is large, N. usambaricus is not in the group of distinctly large and ovate

species. The pronotum is largely devoid of dark maculation. Currently, only the female

is known and the subgenital plate is gently sinuate to the distal spatulate process. Body

length of the neotype is 10.96 mm.

Discussion

This is a newly described species and was first found during these collections. This

species occurred syntopically with N. parviceps at the type locality. Sweeping dense

submerged vegetation along the margins of a small stream yielded nine adults and many

immatures at the type locality and another site further upstream approximately 600 m

higher in the mountains. This species superficially is similar to N. karimii, which is

known from the same general area of the Usambara Mountains in Tanzania, and N.

vaneyeni from the Democratic Republic of Congo. This species is named for Vuga

Junction in the Usambara Mountains near Mombo, adjacent to the stream in which it was

collected.

Diagnosis

This species is large and ovate as are N. karimii and N. vaneyeni (from Democratic

Republic of Congo), but can be diagnosed readily by the male genitalia. Specifically, the

apex of the phallosoma is strongly and sharply hooked to the left, and a subapical

rounded lobe extends dorsally and to the left (Fig. 24). The female subgenital plate is

broad and has a strong mid-lateral projection before narrowing to the distal spatulate

process (Fig. 20). Body length is 10.8–11.9 mm.

Distribution

This species was found at two locations in the river from Soni to Mombo in Usambara

Mountains. The habitat in which it occurred was grassy overhangs and undercuts in a

rocky stream with moderate current.

Distribution Overview

Naucorids were collected at 78 of the 127 collections (61.4%). Of the 14 species of

Naucoridae now known from Tanzania, Macrocoris flavicollis was the most widely

distributed as it was collected in the greatest number of samples (34) and that it was taken

in all six land resource zones (Table 3, Fig. 1). The Highlands land resource zone

harbored the greatest number of species (12); all but Ctenipocoris africanus and

Neomacrocoris parviceps have been recorded from there. From the collections reported

here, two species each were found in only one locality (Laccocoris spurcus congoensis

and Macrocoris sp.), and two others not collected in this project each have been recorded

from only one locality (Neomacrocoris karimii and N. usambaricus). Six species were

recorded only from the East African Rift Valley, suggesting a level of endemism and

degree of restriction in the regional fauna. These species include Neomacrocoris

50

bondelaufa (so named for the Rift Valley), N. handlirschi, Macrocoris sp., Aneurocoris

insolitus, and Laccocoris limicola.

Discussion

Africa harbors a diverse and relatively unstudied fauna in comparison to those of other

continents. The faunas of Australia, Europe, and North America have been studied

heavily over many years and although discovery of new taxa is ongoing, the proportion

51

of known to unknown species is thought to be much higher than it is for Africa. Fewer

and fewer new species are being discovered in temperate regions. Conversely, relatively

little is known of the fauna of tropical regions, including Africa; this disproportionate

level of knowledge is due to several factors. Much of Africa is tropical, although the

northern and southern limits of the continent are temperate. The number of species

increases with proximity to the equator, and tropical forests are thought to hold more than

50% of all species (Lovejoy 1997). As such, the Heteroptera fauna of Africa can be

generalized to be substantially greater than that of similar-sized temperate land masses.

For the Naucoridae alone, the primarily temperate landmasses or regions have low

numbers of species: Australia, 5; Nearctic, 29; Palearctic, 6; whereas the number of

species in primarily tropical land masses is staggeringly higher: Neotropical 186;

Oriental, 78; Afrotropical, 71. Despite the higher number of known species for Africa,

little faunistic research on the Naucoridae has been conducted, and not since the middle

1900s. This research revealed double the number of species occurring in Tanzania than

was previously known. Tanzania is a relatively arid country in tropical Africa, yet the

naucorid fauna was found to be greater than that of Australia, Europe, and all of

Palearctic Asia combined. Further these new species were discovered on the east and

west sides of the country. Given this high diversity for a mostly arid African country and

that three new species were discovered, the diversity and number of undescribed species

of Naucoridae in wetter tropical African countries is predicted to be dramatically higher.

Most areas of Africa have not been sampled for naucorids at all, let alone sufficiently.

Areas that have received moderate collecting are South Africa, Sudan, several national

parks such as Parc National Albert in Uganda, and now also Tanzania. Many species

52

were described from what is now the Democratic Republic of Congo, a large area of

tropical forest in the heart of Africa, but most species are known by only one or a few

specimens. Unfortunately, DRC is not conducive for foreign scientists because of

political instability, civil chaos, and the associated inherent danger. When the situation

becomes more amenable for scientists, this is a region of Africa that should be high on

the list for faunistic exploration because it holds great promise of harboring many

undescribed taxa. Specifically in Tanzania, potential regions that should be targeted for

undiscovered species include the Uldizungwa Mountains, Usambara Mountains,

Ngorongoro Crater, and Mt. Kilimanjaro.

Political instability is among the obstacles for foreign scientific exploration in much of

Africa. Governments of countries that are stable and interested in learning their fauna

should reach out to qualified systematic authorities on taxa of interest by providing

unfettered access to collecting and export permits. Enabling these researchers to conduct

field work that will result in the determination of the local fauna is the only way in which

developing countries will be able to understand the composition of their faunas. In

addition, providing scholarships to promising African students to study in “western”

universities will provide the education and perspective from which to build a human

scientific infrastructure that can work effectively to determine the fauna independently

and with visiting scientists.

The study presented here represents a great deal of field work and taxonomic

investigation because many of these species were known by only a few specimens in

various European, African, and American museums. As such, this study is the first of its

kind in providing an authoritative identification resource to determine the entire fauna of

53

Naucoridae of an African country using modern techniques. Publication of this study can

serve as a model for other African countries to emulate to report the fauna of Naucoridae

or any other group of insects. It is only with resources such as this that scientists and lay

people will be able to acquire insight into and develop an understanding and appreciation

of their local natural world.

CHAPTER 4

TAXONOMIC KEY

Two subfamilies of Naucoridae (Laccocorinae and Naucorinae), each with 3 genera, were

found during this study. The Tanzanian fauna is now known to include 14 species, one of

which is represented by two subspecies. In this chapter, a taxonomic key for

identification of the species of Naucoridae in Tanzania is presented. Note that the key

includes all species that were collected during this study and two species that were not

collected but have been reported in the literature.

VITA

Aaron Y. Mbogho was born on November 27, 1969 in Singida Region and raised at

Mtinko village in the central part of Tanzania. He received both primary and secondary

school education in Singida: at Malolo Primary School (1986) and Mwenge Secondary

School (1990 and 1993) respectively. He received his BSc degree in Horticulture with

honors from Sokoine University of Agriculture (SUA), Morogoro Tanzania in 2002. He

then earned his MSc degree in Entomology from the University of Missouri (MU),

Columbia, USA in 2012. He also completed a course on Sustainable Agriculture at

Navdanaya Agro-Ecological and Biodiversity Conservation Centre in Dehradun, India.

Mr. Mbogho is a Tanzanian civil servant employed by the Ministry of

Agriculture, Food and Cooperatives as Agro-Officer responsible for Plant Health

Services. During his first research work in Diamondback Moth control in 2002, he was

guided by Dr. Myron Zalucki, professor of Zoology and Entomology at University of

Queensland, Australia and he is the first person to work on the Economic Threshold for

Diamondback Moth in Cabbage in Tanzania. He is an apprentice of Dr. Ian F. Grant, a

professor of Ecotoxicology at the Natural Resources Group (the NR-Group) UK and he is

the first person to conduct Rapid Risk Assessment (RRA) of Pesticides and he may still

be the only person with such RRA capability in Tanzania. He has co-authored several

papers with researchers from SUA and MU. He contributed to the first two patents from

SUA: the Portable Double Sided Steel Frame for Log Sawing (Patent # TZ/P/07/00140)

and the Tree Pusher (Patent # TZ/P/07/00143). While pursuing his master’s degree at MU

82

under the advisory and supervision of Dr. Robert W. Sites, a professor of Entomology, he

developed a taxonomic key for 14 known species of Naucorids of Tanzania to include the

two new species: Neomacrocoris bondelaufa and Neomacrocoris vuga they described in

2012. He is a recipient of Thurgood Marshall Fellowship, the prestigious academic

award made by Graduate School. Amongst numerous national and international awards

and recognitions embracing his rich experience, it worth mentioning that he won first

place in Student Competition, Entomological Society of America President’s Prize in

Systematics, Evolution, and Biodiversty category in 2010. He is a permanent member of

the Golden Key International Honour Society validated by University of Missouri,

Columbia for his academic excellence. As a plant protectionist with a precision

agriculture vision, he believes and advocates for Integrated Pest Management techniques.

He enjoys the most when working in Field Crop Entomology especially in the

philosophical ventures such as Economic Thresholds for insect pests.
