An Illustrated Key to, and Diagnoses of the Species of Tenebrionidae (Coleoptera) Associated with Decaying Carcasses in Argentina

Abstract. In this study we identified adults of Tenebrionidae associated mainly with pig carcasses and human cadavers lying in different arid and semiarid areas of Argentina. This article provides an illustrated key to 29 Tenebrionidae species of the potential forensic importance, accompanied by diagnoses, and habitus photographs of these taxa. The recorded species of darkling beetles belong to four subfamilies: Alleculinae (one species of Alleculini), Diaperinae (two species of Crypticini), Tenebrioninae (15 species, ten belonging to the tribe Scotobiini, three to Opatrini, two to Alphitobiini and one species of Tenebrionini), and Pimeliinae (10 species, three belonging to the tribe Epitragini, two to Evaniosomini, two to Praociini, one species from each of the tribes Trilobocarini, Edrotini and Elenophorini). A new species of Eutelocera Solier (Pimeliinae: Praociini) collected from decomposing pig carcasses is described: E. cadaverina Flores and Zanetti sp. nov. Two species are new records for Argentina...
