RT Journal Article T1 An illustrated key to and diagnoses of the species of Histeridae (Coleoptera) associated with decaying carcasses in Argentina JF ZooKeys JO ZK FD Pensoft Publishers DO 10.3897/zookeys.261.4226 VO 261 A1 Aballay, Fernando Hernán A1 Arriagada, Gerardo A1 Flores, Gustavo A1 Centeno, Néstor YR 2013 UL https://doi.org/10.3897/zookeys.261.4226 AB A key to 16 histerid species associated with decaying carcasses in Argentina is presented, including diagnoses and habitus photographs for these species. This article provides a table of all species associated with carcasses, detailing the substrate from which they were collected and geographical distribution by province. All 16 Histeridae species registered are grouped into three subfamilies: Saprininae (twelve species of Euspilotus Lewis and one species of Xerosaprinus Wenzel), Histerinae (one species of Hololepta Paykull and one species of Phelister Marseul) and Dendrophilinae (one species of Carcinops Marseul). Two species are new records for Argentina: Phelister rufinotus Marseul and Carcinops troglodytes (Paykull). A discussion is presented on the potential forensic importance of some species collected on human and pig carcasses.
