Monographic revision of the genus Aegidinus Arrow (1904)and generic phylogeny of the world Orphninae(Coleoptera: Scarabaeidae: Orphninae).

  • A taxonomic revision was performed on the New World scarabaeoid genus Aegidinus Arrow (Coleoptera: Scarabaeidae: Orphninae). Twelve new species and three previously described species are included in the revision. Keys to New World genera, species of the genus Aegidinus, and distribution maps are provided. Phylogenetic analyses of the world genera of the Orphninae were conducted using 30 adult, morphological characters from representatives of 13 of the 14 genera and three out-group taxa. The subfamily Orphninae is a strongly supported monophyletic group (bootstrap support 88-90%) with respect to the chosen out-group. Characters that support the Orphninae are: mandibles not sickle shaped, molar surface on the mandibles present, lacinia present, and stridulatory comb present. Separate Old and New World lineages are also supported by the phylogeny, when two genera, Goniorphnus Arrow and Stenosternus Karsch, are excluded from the analysis. The new species described are: Aegidinus cornutus Colby, A. crypticus Colby, A. howdenorum Colby, A. howeae Colby, A. oreibates Colby, A. petrovi Colby, A. simulatus Colby, A. sunidgea Colby, A. teamscaraborum Colby, A. tricornis Colby, A. unicus Colby, and A. venezuelensis Colby.
