Face flat, sometimes with carina very shallow. Arista with zero or one ventral branch except for apical fork. Eyes usually bare, occasionally with very fine, sparse interfacetal setulae. Wing membrane usually hyaline, sometimes entirely dusky or with diffuse clouds of infuscation on costal region, over dm-cu and at apex of R2+3. A1 + CuA2 and A2 absent or vestigial. Crossveins bmbr and bm-cu absent; cell br open basally. Male genitalia with ventral margins of cercus often extended ventrad; surstylus essentially clavate, but variable, never with peg prensisetae; phallus varying from simple conical or very complex hooked forms in variable degrees of sclerotization; hypandrium usually Y-shaped, with a ventral keel. Female genitalia reduced; oviscapt not developed; spermathecal capsule highly vestigial or absent; ventral receptacle developed but not sclerotized.
