Clavlger longicornis P. W. 1. M ti I Ie I' is distributed throughout Europe except for itsnorthern parts and the Mediterranean subregion (B e sue het 1974). Within this rather widerange, however, the findings of this are generally quite sporadic and rare. The same situationhas been in the territory of the former Czechoslovakia, data in the literature on the occurrenceof C. longicornis in its individual parts being very scarce.

The first record in the former Czechoslovakia comes from Bohemia from the middleof the 19th century and documents the occurrence of C. longicornis at Zavist near Prague(L 0 k a y sen. 1860). Two major papers on Bohemian myrmecophilous insects, containingfurther data on the occurrence of C. longicornis, were published at the beginning of the20th century. L 0 k ay jun. (1905) repeatedly found the species at Zavist near Prague,and R 0 u b a I (1905) reported it, in addition to that, from the wider environs of Prague(Praha, Vrane, Nernelkov, Chuchle and Zavist) and furthermore from Susice in southernBohemia. Of the later comprehensive papers on Bohemian myrmecophilous insects, onlyRoubal (1949) reports Its occurrence in eastern Bohemia (Choceri, Ustf nad Orlicf). Thepapers on myrmecophilous beetles by R a m b 0 use k and S a m Si nu k do not mentionC. longicornis. M ti II er (1863) did not include the species in his first list of Moravianbeetle species. In a second, more detailed list of beetle species of Moravia and AustrianSilesia, Rei t t e I' (1870) records a single finding of C. longicornis by A. Fleischer in theTesrnske Beskydy Mts. (beneath stones among minute yellow ants in April, very rare). Thespecies has not been listed by S t e j s k a I (1925), whose paper is still the only evaluationof rather extensive collections of Moravian myrmecophilous beetles. His paper is only aspecies list supplementing the lists by Lokay jun. (1905) and Roubal (1905). In hislist, S t ej s k a I (1925) has included species not previously published as living among antsin Bohemia and Moravia; altogether they are accidental findings of beetles among ants.not true myrmecophilous species. Nor is C. longicornis represented in the collection ofmyrrnecophilous beetles of 1. V. Stejskal, who was among the staff of the Department of

177

Entomology. Moravian Museum. for a number of years. His collection is deposited in thatdepartment and was examined by P. Lauterer. A general note on the possible occurrenceof C. longicornis in Moravia is found in FIe i s ch er's (1927-1930) "Review of Beetles".p. 168 (sep. p.): "everywhere but altogether more rare, likewise among ants Lasius flavusand utnbratus", R 0 u s (1993) has not included this species in his latest list of the Moravianpselaphid fauna. Bat elk a (1993, Klapalekiana 29: 167) published one finding as a newspecies for the Moravian fauna. The occurrence of C. longicornis in Slovakia has beenreported in scattered localities summarized by R 0 u b a 1 (1930) for the first time. The firstrecord dates back to the late 19th century (K u thy 1896) and another follows shortlythereafter (B 0 Ik ay 1907: Kalnica both records ex R 0 u b a 1 1930). Additional localitieswere supplemented by Roubal (I. c.): Trencfn, Hronska Breznica, Rimavska Sobota. Newdata have been published by Franc (1992) who states that a relatively large number offindings at an earlier date has been known from Slovakia but that at present the species hasbeen only rarely collected in the localities at Dubova, Jablonov nad Turriou and Cabrad. Hisobservation that the species inhabits warm habitats agrees with our own results.

The material collected by us is partly deposited in the collections of the Department ofEntomology, Moravian Museum in Brno, and partly in the private collections of P. Bezdeckaand P. Prudek. The findings are largely the results of extensive faunal investigations of P.Be z de <: k a (17 collections) as by-products of investigations into the ant fauna. Unlessotherwise stated in the text for each individual finding, P. Be z d e<: k a is the collector andperson responsible for the identification. At present, this author has been preparing a morecomprehesive paper on the distribution of Formicoidea in Bohemia and Moravia, based onthe new taxonomy of this insect group (B e z d e ~ k a, in prep.). The numerical designationof faunistic quadrats comprising each locality are stated in accordance with Ze 1e n y (1972).

At present, Claviger langicornis M i.iII er is none too rare in Moravia and we havecollected it several times during the past 40 years. Our first finding dates from 1951, ourlatest one from 1993.

In all, we have found 33 specimens in 19 collections. The beetles mostly occurredsingly: as exceptions we have found, in one ant colony, 3 specimens and in the subsequentyear 5 specimens (with an unidentified species of the subg. Chthonolasius); once we found6 specimens with L. jensi Se ife rt , and 2 specimens each with L. jensi Se i f.; andL. brunneus (L a t r. ). Most frequently, C. longicornis occurred with ants of the subg.Chthonolasius: 25 specimens in 12 collections; with L. umbratus (N YI . ), 6 exx. in6 collections; with L. brunneus (L a t r. ), 6 exx. in 5 collections; with L. jensi Se i f e rt ,10 exx. in 4 collections; with an unidentified species of the subg. Chthonolasius, 8 exx.in 2 collections in a single colony; and one specimen each with L. alienus (F 0 er s t. ) ,L. platythorax Seifert, and L. rabaudi (Bondroit). The species has also been foundtogether with Claviger testaceus P re y s s I er in a number of specimens of both species.

Most of the specimens (26 exx.) have been found beneath small and flat stones (in12 cases). In four cases, I specimen each was found beneath the bark of tree trunks orstumps and in one case 2 specimens. In tree stumps the species has been found in two cases,I specimen each. These observations suggest that the beetle, like the related C. testaceus,has the habit of warming itself beneath sunlit stones and bark, especially in spring, togetherwith the host ants but rarely together with their larvae or pupae.

The beetles have been found at low elevations ranging between 180 and 400 m; rarelyin ftoodplain forests (180-270 m) with L. brunneus (Latr.) (4 cases) and L. platythoraxSe i fe rt (1 case), all those cases I specimen each; most frequently they have been found inxerothermic, often limestone localities on south-facing hillsides, evenly distributed between250 and 400 m (occasionally also 200 m) above sea-level, comprising all other 14 findingstotalling 28 specimens.

The clavigerid under study rarely occurred for the first time around mid-March (\ 2and 17 March, I ex. each), most frequently between 31. iii. and 23. iv. (9 cases, 16 exx.).frequently also between early May and the first decade of June (I. v.-8. vi., 12 exx.), inwhich period there is still enough moisture on the surface of ant colonies. A single findingwas made in summer (10. viii., I ex.) and the species occurred singly still in the Ist half ofautumn (18. x.-2. xi., 2 findings of I ex. each).
