Abstract

In the Neotropics, orphnine scarab beetles are represented by the endemic tribe Aegidiini Paulian, 1984 with five genera and over 50 species. Phylogenetic analysis based on morphological characters of all supraspecific taxa of Orphninae showed that Aegidiini is comprised of two lineages. New subtribes, Aegidiina subtr. nov. (Aegidium Westwood, 1845, Paraegidium Vulcano et al., 1966, Aegidiellus Paulian, 1984, and Onorius Frolov & Vaz-de-Mello, 2015, and Aegidininasubtr. nov. (Aegidinus Arrow, 1904) are proposed to better reflect this phylogeny. Two new species of Aegidinus are described: A. alexanderisp. nov., from the Yungas in Peru and A. elbaesp. nov. from the Caqueta moist forests ecoregion in Colombia. A diagnostic key to Aegidinus species is given.
