First records of Bessierus doloris Thomas & Orth (Ephemeroptera: Leptophlebiidae) in Brazil

Abstract

We report the first occurrence of Bessierus doloris in Brazil. Additionally, we provide biological and taxonomic information on this species. Male imagos specimens were collected with a Pennsylvania light trap in the Apiaú region, municipality of Mucajaí, Roraima. The discovery of this species in Brazil extends its geographic distribution further west in South America, reaching about 100 meters in altitude above sea level.
