﻿AbstractIn the Neotropics, orphnine scarab beetles are represented by the endemic tribeAegidiiniPaulian, 1984 with five genera and over 50 species. Phylogenetic analysis based on morphological characters of all supraspecific taxa ofOrphninaeshowed thatAegidiiniis comprised of two lineages. New subtribes,Aegidiinasubtr. nov. (AegidiumWestwood, 1845,ParaegidiumVulcano et al., 1966,AegidiellusPaulian, 1984, andOnoriusFrolov & Vaz-de-Mello, 2015, andAegidininasubtr. nov.(AegidinusArrow, 1904) are proposed to better reflect this phylogeny. Two new species ofAegidinusare described:A.alexanderisp. nov., from the Yungas in Peru andA.elbaesp. nov.from the Caqueta moist forests ecoregion in Colombia. A diagnostic key toAegidinusspecies is given.
