Abstract
Whilst sorting Malaise trap material from Pantanal, in western central Brazil, a not readily identifiable species of Denopelopia Roback et Rutter, were found. This genus has no formal species described or recorded in Brazil, except for a larval morphotype recorded by Trivinho-Strixino & Strixino (1995). According to Ashe & O´Connor (2009), Denopelopia comprises 4 species known from the Nearctic, Neotropical, eastern Palearctic and Oriental regions (viz. D. atria Roback & Rutter, 1988; D. diaoluonica Cheng & Wang, 2005; D. irioquerea Sasa et Suzuki, 2000 and D. viridula Cheng & Wang, 2005). A key of adult males was given by Cheng and Wang (2005). The found species is regarded as new and described here.
