Abstract

In the Neotropical Region, Orphninae (Coleoptera: Scarabaeidae) are represented by the endemic tribe Aegidiini, which comprises five genera and 49 species (Paulian 1948; Colby 2009; Frolov & Vaz-de-Mello 2015; Frolov et al. 2017a, 2017b, 2017c, 2019). Aegidium Westwood is the largest genus of the tribe and it comprises 24 valid species known from the southern Mexico in the north to Central Bolivia in the south (Frolov et al. 2015; Rojkoff & Frolov 2017; Frolov & Akhmetova 2020).
