Coenosia poecilotarsis ( Emden, 1940: 161)

Holotype male seen; scutum damaged.

Diagnosis. General colour brown with grey pollinosity; scutal colour pattern very distinctive in the genus, with two round brown spots on presutural area, and a transverse brown broad band behind the suture; scutellum also with a broad brown band not reaching the apex; postpedicel broad and long; palpus brown; legs yellow, dorsal surface of the femora a little grey infuscated; arista almost bare; scutellum with both pairs of setae long, and with setulae on disc; anterior katepisternal of medium size; lower calypter large, about twice as long as the upper one; haltere yellow; male fore tarsomeres 2–5 dilated, tarsomeres 2–4 black on basal half and yellow on apical half; fore tibia without median seta; hind tibia with one anterior, one anterodorsal and one posterodorsal inserted basad of the others.

Notes. The species keys out as an isolated species in the group key and is very easy to recognize by the colour pattern of the scutum and the modified fore tarsomeres. Known only from the holotype male.
