Shilenkov, V. G.: Species of the subgenus Diocarabus Reitter (Coleoptera, Carabidae) from Siberia

ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Tomus 75. , Budapest, 1983 p. 145-153. Species of the subgenus Diocarabus Reitter (Coleoptera, Carabidae) from Siberia by V. G. SHILENKOV, Irkutsk Abstract — Subgenus Diocarabus REITT. includes 6 species, one of them from Transbaikal region (Carabus dorogostaiskii sp. n.) described as new. Subgeneric name Allocarabus LAP. reduced to synonym. 6 photographs of all species. 36 figures of genital organs and identification key to species are given. The species of the subgenus Diocarabus REITT. are distributed in Siberia from the Ural Mts. to Sakhalin Isl. and from Yakutiya and Magadan district to Northern Mongolia, Northern China and Northern Korea. They inhabit wooded and mountainous territories, some of them live in subalpine zone or in mountainous tundra. The intention of this article is a taxonomical review of the species, moreover new data on distribution and ecology are given. I wish to express my hearty thanks to all the colleagues and friends, who helped me in this study by supporting the work or giving specimens: Dr. O. L. KRYZHANOVSKIJ, Dr. Z. KASZAB, Dr. V. G.

Diocarabus REITTER, 1896: 185. — Allocarabus LAPOUGE, 1921, Misc. Ent.. 25: 121, syn. n. Type-species of subgenus : Carabus loschnikovi FISCHER VON WALDHEIM. Section Diocarabus was established by REITTER for Carabus loschnikovi F. -W. and C. massagetus MÖTSCH. (C. dohrniREITT., non GEBL.). Later A. SEMENOW (1898: 539) included in this section C. loschnikovi F.-W, C. truncaticollis ESCHSCH., C. aurocinctus MÖTSCH, and C. massagetus MÖTSCH. (C. dohrni SEM. nec GEBL.). In the catalogue of JAKOBSON (1906: 251) to these species were added C. polaris POPP, and C. slovtzovi MNNH. C. massagetus MÖTSCH, was ranged among the section Apostocarabus REITT. In 1921 LAPOUGE allocated C. aurocinctus MÖTSCH, to the section Allocarabus on the basis of such morphological characters as multisetose labial palpi and strong reduction of quaternaries. The first character is only misunderstanding, and the second cannot be adopted as satisfactory reason for the erection of a distinct subgenus. I include in the subgenus Diocarabus REITT. the following species: C. loschnikovi F.-W., C. massagetus MÖTSCH., C. slovtzovi MNNH., C. dorogostaiskii sp. n., C. beybienkoi KRYZH. and C. aurocinctus MÖTSCH. Diagnosis. — Species of small and middle sizes. Apical segments of palpi in male and female hardly dilated, labial palpi bisetose. Mentum tooth sharp and narrow, equal or somewhat shorter then lobes, mentum not thickened, submentum with 2 pores. Antennae short, reaching to basal third of elytra, their intermediate segments simple in male. Pronotum with 2 (rarely with 3-4) lateral setae, sides narrow bordered, not flattened and reflexed, hind angles slightly produced backwards and rounded. Elytra convex, hardly emarginate before apex, between two rows of large foveae situated 5 intervals, rarely quaternaries strongly reduced. Sternites smooth or with trace of transverse wrinkles. Hind tibiae from above with distinct longitudinal grooves. Annls hist.-nat. Mus. natn. hung.. 75, 1983 10 Természettudományi Múzeum Évkönyve 1983
