Introduction In recent years some new genera of Cryptophagidae were described from Nepal by Leschen (1996) (Asternodea, Striatocryptus) and by Sen Gupta & Pal (1980) (Himascelis). Additionally, somenewspecies ofthe genusAnitamaria Leschen 1996 *> Results of the Himalaya Expeditions ofJ. Martens, no. 218. - For no. 217 see: Bonner zool. Beitr. 47, 1997. -J.

Thus, Nepalpos- sesses a quite diverse, autochthonous fauna of Cryptophagidae (besides the synan- thropic species). The present paper is based on the material lent to me by Dr. W. Schawaller (Staatliches MuseumfürNaturkunde in Stuttgart). In this material afurthernew ge- nus of Cryptophagidae was discovered. Its description is given below. The material described is deposited in the Staatliches Museum für Naturkunde in Stuttgart (SMNS) and the Zoological Museum ofMoscow University (ZMUM).

It clearly dif- fers from the tribe Hypocoprini, however its place in the more evolved tribes A Cryptafricini and Atomariini within the Atomariinae requires further study. sep- arate studywill be devotedto this question, because the newgenus cannotbeplaced in all existing tribes of Atomariinae (Leschen 1996) without detailed discussion. Here it is possible to make only preliminary remarks, concerning the differences of Scytomaria n.gen. fromvarious groups ofAtomariinae. The differences fromthe Hypocoprini are thefollowing: transverse line onvertex of the head absent (present in Hypocoprini); metasternal glandular ducts present (absent in Hypocoprini); one glandular duct at lateral edge of each ventrite present (absent in Hypocoprini). LYUBARSKY,ANEWGENUS OF CRYPTOPHAGIDAE 5 The differences from Ephistemus and related genera are the following: prothorax parallel-sided (widened basally in Ephistemus); external closure of procoxal cavity partially closed (completely open posteriorly in Ephistemus); orientation of aedea- gus in the abdomen vertical (horizontal in Ephistemus); arms of tegmen fused and forming an elongate process (arms separate and process shorter in Ephistemus); spiculum gastrale ofmale narrow (broad in Ephistemus); apical tibia fringe ofspines absent (presentinEphistemus); basalbindingpatch ofhindwingpresent (poorlyde- veloped in Ephistemus). Scytomaria n.gen. is similar to the Atomariini in the following features: puncta- tion in prosternal area present; median process of mentum present; transverse ridge on mentum present; glandular ducts on mesosternum present; surface ofventrite V unmodified, apex ofendophallus rounded basally, hind wing bindingpatchpresent. A strong similarity is observed also with Cryptafricini in the following features: apical antennomere2times longerthanprevious antennomere; gularsuturespresent; pronotal bead present in basal half; procoxal cavity closed internally; pit on mes- epimeron absent; concentration ofsetae atpresentpores ofglandular ducts; glandu- larducts ondiskofventriteI absent;orientationofaedeagusvertical;arms oftegmen fused and forming an elongate process; spiculum gastrale of male narrow; setae on anterioredge ofpraescutumpresent; marginal setae ofleadingedge ofhindwingex- tending beyond level ofRA + ScPvein; apical fringe oftibial spines absent.

Antennae long, extending beyond the basis of pro- thorax. Segment I not curved, conical; segment II equal on length to the 1th, slight- ly thinner; segment III somewhat shorter and thinner; segment IV 1.5times shorter than 3rd; segment V very elongate and thin, clearly longer than 3rd; segment VI equal to 4th; segment VII equal to 3rd, but thinner; segment VIII subquadrate; seg- ment IX lengthened; segment X slightly transverse; segment XI lengthened, longest ofall antennomeres. Prothorax broadest before middle, where it is 1.2times as broad as long, slightly shagreened, somewhat densely covered with small punctures, latter on the average one diameter apart from their lateral neighbours. Anterior edge straight, posterior edge slightly convex, with a weak lobe medially. Prothorax without basal pits, with deep transverse impression, lateral edge slightly bordered, slightly concave in basal half. Elytra strongly convex, at shoulders muchwider thanprothorax, 2.4-2.6times as long as prothorax and about 1.2-1.3times as long as combined width, with humeral 6 STUTTGARTERBEITRÄGE ZURNATURKUNDE Ser. A,Nr. 572 prominence, without humeral tooth, slightly shagreened, puncture in basal part hardly stronger or equal to those on pronotal disk and about one diameter apart from their lateral neighbours on the average. Elytra separately rounded apically, apex ofabdomenvisible from dorsal view. Hindwings fully developed. Aedeagus as in fig. 6.

Introduction TheBruchidiusseminarius group contains bruchid species withvery similarchar- acteristics which often cause difficulties in differentiation. Borowiec (1985) gives descriptions, redescriptions andfigures ofmale genitaliaand records 10 species with the following combination of characters: body oval; antenna short in both sexes withoutsexualdimorphism; elytral basewith orwithouttubercle; hind tibiastrong- ly broadened, mucro distinctly longerthan coronal denticles; male genitalia: median lobeshortwithventralvalvetriangular,internalsac subbasallywithdistinctsclerites, lateral lobes simple withoutkeel attheir base. Aldridge & Pope (1986), Borowiec (1987), Borowiec & Anton (1993), and Decelle & Lodos (1989) give further in- formation on the B. seminarius group. Bruchidiusapicipennis (Heyden), mentioned in Borowiec (1985) as a member of theB. seminarius group, shows adifferentcombination ofcharacters and belongs to the B. apicipennis group. The present paper adds further details to the knowledge ofthis group. Addition- aldiagnostic characters areadistinctspotofdenserandlongerhairs atthebasalmid- dle ofthe male abdominal sternite one in 7 species (Tab. 1). This characteris similar- ly developed in all species ofthe B. albosparsus group. A general picture of the important characters and the global distribution of the species ofthe B. seminarius group is given inTab. 1 and Figs. 1-12. In the following part a new species is described: Bruchidius borowieci. Further on, additional synon- ymies and less known species are treatedconcerningtypes and misidentifications. A redescription ofB. taorminensis is given. Finally, an identification keyfor all species oftheB. seminarius group is presented, based on external morphological and colour characters. 2.
