Etymology. Named after Dr. Marcello G. Simões, paleontologist from the Department of Zoology at Instituto de Biociências, Universidade Estadual Paulista (UNESP, Botucatu campus).

Diagnosis. Within the genus, E. simoesi n. sp. can be recognized by the following characters: male FWs medium brown, short, rounded, margins light brown; covering metanotal gland area but not surpassing the metanotum. Metanotal gland present, but without cluster of bristles, composed of two short projections with rounded top. Apex of pseudepiphallic arms bifid, divided in two dorsal, and a ventral projection, with bristles; dorsal projections of the apex pointed, curved, ventral projection thin, elongate, pointed, almost straight; ectophallic arc located posteriorly to the median part of pseudepiphallus, near the PsP2; dorsal projections of ectophallic invagination (D.P.Ec.) short, sclerotized, clearly separated.
