Postpronotum and notopleuron silver pruinose. Dorsocentrals 2+3. Haltere brown. Calypters white. Legs. Brown. Fore tibia without a posterior seta. Mid tibia with 1 posterior seta; in male enlarged on apical third and with many short setae on all surfaces, longer apicad. Hind femur with an anteroventral row of setae on apical half. Hind tibia with 2–3 anterodorsal setae on middle third; 1 submedian anteroventral; without posterodorsal. Arolium and pulvillus not enlarged. Wing. Costal spine indistinct. M slightly curved forward close to apex. Abdomen. Dark brown, with a median silver pruinose vitta and lateral spots on all tergites.

Remarks. The species can be immediately recognized in the male by the enlarged apical third of mid tibia, with many short setae in all surfaces which become longer apicad. It can be identified with the key by Stein (1911, as Limnophora clavitibia ).
