Denopelopia moema, a new Tanypodinae (Diptera: Chironomidae) from the Neotropical Region.

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. The specimens were slide-mounted in Euparal. Morphological terminology and abbreviations follow Sæther (1980). Mensural data are given as ranges, with the number of observed specimens in parenthesis if different from the number (n) stated at the beginning of the description. The holotypes and paratypes are deposited in the Museum of Zoology of the University of São Paulo.
