Taxonomic revision of Erebidus Reichardt, 1941 (Coleoptera: Histeridae) with comparative morphology of E. vlasovi and E. reichardti

Based on newly collected material, we present a comparative redescription of two histerid beetles: Erebidus vlasovi (Reichardt, 1941) and the poorly known E. reichardti (Tishechkin & Lackner, 2012). The study includes a diagnostic key emphasizing subtle morphological characters and a table of principal morphometric parameters for Erebidus species. The study offers the first analysis of female genitalia of both species, revealing gonocoxal similarities between E. reichardti and other Saprininae, while variability in gonocoxal structure within the genus may indicate its polyphyletic nature.
