Autapomorphies : postvertical bristles more or less divergent; prothoracic presternum broadened; fore basitarsus with some bifurcate ventral setulae; anal crossvein (CuA 2 + A 1 ) obsolete. Shared apomorphies : claws differentiated into slender basal shaft and broadened distal falx (shared with Dasyrhicnoessa , condition reversed in Suffomyia ismayi ); in compound protandrial sclerite, area of tergite 6 markedly greater than area of sternite 8 (shared with Canacinae ). Possible apomorphy (relative to groundplan of Chloropoidea ): eye with well-developed ommatrichia, c. as numerous as ommatidia (shared with some Tethininae ). Distribution .
