A research on the homologies of various characters of the body and of the complete ectodermic male genitalia has been made on all the nomenclatural genus-group taxa included in the polyphyletic genus Passalus Fabricius, 1792, of the American tribe Passalini Leach, 1815. This work allows a re-evaluation of the typological systematics. The splitting of Passalus, s. auct., is a requirement for a phylogenetic reality with monophyletic species groups. In this first issue seven genera have a new status : four belong to the “ Passalus-Paxillus lineage” and three to the “ Pertinax lineage” sensu Boucher (2006). For each genus are given diagnostic characters, the main endemism and a preliminary number of representative species. The 21 synonyms of th...
