. The study of specimens previously identified as Bisnius scribae (Fauvel, 1867) or B. scribae var. heidenreichi Hubenthal, 1911 from Russia and Ukraine revealed their identity as B. pentheri (Ganglbauer, 1905) which was hitherto known from Turkey and Armenia. Comparison of B. nigriventris (Thomson, 1867) with the type material of B. pseudoparcus kasatkini Khachikov, 2003, described from the Northern Caucasus, revealed their complete identity. As a result, the following new synonymy is established: Bisnius nigriventris (Thomson, 1867) = B. pseudoparcus kasatkini Khachikov, 2003, syn. n., and B. nigriventris is recorded for the North Caucasus for the first time. Currently, the following 16 species from the genus Bisnius Stephens, 1829 are known from the territory of southeastern Ukraine and the south of the European part of Russia: B. cephalotes (Gravenhorst, 1802), B. manytchensis Hatchikov, 2003, B. nitidulus (Gravenhorst, 1802), B. parcus (Sharp, 1874), B. pseudoparcus (Brunne, 1976), B. pentheri, B. nigriventris, B. scribae (Fauvel, 1867), B. puella (Nordmann, 1837), B. spermophili (Ganglbauer, 1897), B. fimetarius (Gravenhorst, 1802), B. reitteri (Eppelsheim, 1889), B. sordidus (Gravenhorst, 1802), B. subuliformis (Gravenhorst, 1802), B. speculicollis Solodovnikov et Schillhammer, 2000 and B. zhuk (Gusarov, 1995).
