Acroceridae (Diptera): a pictorial key and diagnosis of the Brazilian genera

Abstract

There is no catalog or identification keys for Brazilian genera and species of Acroceridae. This paper provides, for the first time, a key and diagnosis of the Brazilian genera of the Acroceridae, based on morphological characters and illustrated with photographs. The key and diagnoses are based on morphology rather than on color as has been used in previous studies. The key includes nine genera: Acrocera Meigen, Exetasis Walker, Lasia Wiedemann, Ocnaea Erichson, Ogcodes Latreille, Philopota Wiedemann, Pialea Erichson, Pterodontia Gray and Terphis Erichson.
