Belongs within: Ephydroidea.
Contains: Drosophila.

The Drosophilidae are a family of generally small flies, often feeding on fungi as larvae. Most species have plumes on both sides of the antennal arista, and three pairs of fronto-orbital bristles with the anterior pair proclinate and the remainder reclinate (Grimaldi 2010). They have been divided between two subfamilies, with the Steganinae possessing a pair of large prescutellar setae and two large katepisternal setae whereas Drosophilinae have no prescutellar setae and one large and one small katepisternal seta (Grimaldi 2010). The great majority of species of Drosophilinae are currently included in the (probably non-monophyletic) genus Drosophila.

Characters (from Grimaldi 2010, Colless & McAlpine 1991): Antennal arisa usually plumose, sometimes with just ventral branches absent, occasionally with all branches of arista absent; antennal segment 2 cap-like. Frons with three pairs of fronto-orbital setae, anterior-most pair proclinate, rear two pairs reclinate; anterior reclinates often small, sometimes reduced or lost; postverticals more or less convergent. Costa broken beyond hm as well as Sc; Sc obsolete apically, free from R1. Mesopleural bristle absent.
