Abstract

Neotropical species of Decevania Huben, 2003 are revised for the first time. Species in this genus are characterized by having an 8-segmented flagellum, eye relatively reduced, wings frequently large and floppy with reduced venation (M+CU, 1CUa, 1Cub and 2CU), anterior wing with only one cell enclosed by tubular vein (costal), and hind tarsomere 1–3 posteriorly expanded. Thirteen species are recognized, two of which were previously described, D. parva (Enderlein, 1901) and D. striatigena (Kieffer, 1910), and eleven which are described and illustrated as new; D. brevis sp. nov., D. deansi sp. nov., D. destituta sp. nov., D. elongata sp. nov., D. glabra sp. nov., D. hemisphaerica sp. nov., D. nigra sp. nov., D. nuda sp. nov., D. polita sp. nov., D. reticulata sp. nov., D. unidentata sp. nov. Keys for species identification based on males and females are provided.
