Ecuador

Onorius inexpectatus

Frolov, A.V., Vaz-De-Mello, F.Z. 2015. A new genus and species of Orphninae (Coleoptera: Scarabaeidae) associated with epiphytes in an Andean cloud forest in Ecuador. Zootaxa, 4007 (3): 433–436

Orphninae (Coleoptera: Scarabaeidae) are represented in the New World by the tribe Aegidiini, which is comprised of four genera (Paulian 1984). Examination of material collected in Ecuador revealed a series of the Aegidiini specimens from an undescribed species that cannot be classified as a member of one of the known genera. The new species is herein described and a new genus is established. Apart from the distinctive morphological characters, the new taxon shows an unusual, for the Orphninae, association with canopy epiphytes.
