IntroductionMost of the scattered work on Indian Allantinaewas published by Malaise (1934, 1935, 1945,1957,1961). Later, Malaise (1963) also presented
a key to the world genera of Selandriinae (cur-rently including the subfamilies Selandriinae, He-tarthriinae, Allantinae, Nematinae and Blenocam-pinae). No new genera of the Allantinae have been
added to the Indian fauna since the publication ofMalaise's key. With the addition of the genus
described below, the number of allantine genera
in India now scores 18.
Abbreviations: (EL) eye length, (IATS) inner apicaltibial spur, (lCD) intercencheri distance, (IDMO) intero-cular distance at level of front ocellus, (lTD) intertegulardistance, (LID) lower interocular distance, (MB) meta-basitarsus.

Manis gen. n.
Description of female
Heacl. Antenna with 9 segments: apical 4 seg-
ments compressed. Clypeus with circular incisionup to 2/5 of its medial length and with blunt iateralteeth (Fig. 1). Mandibles symmetrical and bentalmost at right angle. Eye protruding (Fig. 2); lo-wer margin reaching below level of antennal soc-ket. Frontal area elevated at level of eyes. Headparallel posterior to eyes (Fig. 2).
Legs. Tarsal claw with long apical and relativelyshort subapical tooth (Fig. 3); basal lobe absent.
l4zings (Figs 4, 5). Anal cell cross vein on forewing somewhat oblique (Fig. a). Hind wing with-out closed middle cell; anellan cell petiolate; ner-vellus curved towards anellan petiole, but almostperpendicular to brachiellan vein (Fig. 5).
Etymology. The genus is named after Dr M. S.
Mani, an authority of Himalayan ecology in India.The gender is masculine.
T.y-pe species. Manis himalavensls sp. n. by presentdesignation. The genus is monobasic.
D istibution. India, Himachal Pradesh.Remarks.In Malaise's (1963: 179-180) key to theworld genera, the new genus runs to couplet 106,where it differs from both genera keyed out here,i.e. Malochiella Malaise and Heptapotamius Ma-laise (note that Mallat'hiella Malaise, 1963, is an
unjustified emendation). The head of Manis issubparallel behind the eyes, whereas it is evidentlybecoming narrower posteriad in both other genera.
Other differences lrom Malachiella are: (l) tarsalclaw with subapical claw short (long in Malac-hiella) and basal lobe absent (minute in Malac'-hiella), and (2) mandibles symmetrical (subsym-metrical in Malachiella). It diff'ers fron.rHeptapotamiu.s in the more protruding eyes andthe compressed flagellum of antenna (not com-pressed in H e ptapotamius).

Type material. Holotype: female, Himachal Pra-desh, Dalhousie, Kalatop, 2,380 m a.s.l.,25.vi.1986. Paratypes 13d I ? with same data as
holotype. Type material deposited in Indian Agri-cultural Research Institute, New Delhi.
Etymology. The species is named after the "GreatHimalayas", where the type locality is situated.
Distribution. India. Himachal Pradesh.
Remarks. Manis himalayensis is most similar toMalachiella rufithorax Malaise. The two speciesare easily separated on the generic characters.
