Hesperiidae of Rondônia Brazil: <i>Eracon </i>and a new related genus, with descriptions of two new species (Lepidoptera: Hesperiidae: Pyrginae).

Abstract

Five species of Eracon were encountered near Cacaulândia in central Rondônia, Brazil of which one, Eracon asymmetrica n. sp., is described as new. Cornuphallus n. gen. is proposed as a new genus for Eracon(?) problematica, and Cornuphallus albafascia n. sp. is described from central Rondônia. Male genitalia are illustrated for all species encountered (E. bitemata for the first time). Female genitalia of Eracon have not been illustrated heretofore and those of E. clinias, E. paulinus, and E. asymmetrica are shown.
