Comprehensive DescriptionRead full entry
Ocyptamus is a large Syrphini genus endemic to the New World with over 300 Neotropical species and 22 Nearctic species (Rotheray et al. 2000). Species of this genus show much greater variation in colour pattern and body shape than those of any other genus of the tribe Syrphini, and they also show more variation in the male genitalia than those of most syrphid genera (Vockeroth 1969).
Ocyptamus fascipennis has abdomen petiolate, wing with atransverse brown vitta, basal cells bare basally, costal cell dark brown on apical 2/5, and cell r4+5 entirely microtrichose.
