Differential diagnosis. Dermestes (Dermestes) bicolor cernyi ssp. n. belong to „ D. bicolor species group“ defined by Kalík & Ohbayashi (1982); in Palaearctic region this group presented of 8 species and subspecies; the new subspecies similar of the pubescence on dorsal surfaces to D. (D.) bicolor bicolor Fabricius, 1781 and D. (D.) bicolor sinensis Háva, 2004. Moreower, it is separated from D. bicolor bicolor Fabricius, D. (D.) bicolor sinensis Háva, 2004 and D. bicolor impressus Pic (north Africa) by different structure of the male genitalia and elytral striae of the new subspecies very flat.

Name derivation. Patronymic, dedicated to the collector of the new subspecies, my friend, Zdeněk Černý (Mírovice, Prague-east, Czech Republic).
