After a decade, a new Venezuelan species of Corydalus Latreille (Megaloptera, Corydalidae, Corydalinae) is discovered

Abstract

A new species of dobsonfly from Venezuela, Corydalus ralphi Martins, Azevêdo, Hamada & Contreras, sp. nov., was discovered a decade after the last description of a species of this genus in the country. The new species is morphologically similar to C. wanningeri Contreras-Ramos & von der Dunk, sharing a uniform reddish coloration of body and wings and similar male genitalic structures. Likewise, it shares this particular coloration with C. neblinensis Contreras-Ramos but the genitalic structure fits within the C. crossi Contreras-Ramos species group. Two specimens, one male and one female, were collected on Tarotá River, in the Gran Sabana region, Canaima National Park, in southern Venezuela. A key to identify males of the Venezuelan species of Corydalus is provided.
