Legs yellowish-brown, hind femur brown at apex. Foretibia with one dorsal seta at basal quarter and anterodorsal row of strong setae. Midtibia with two basal transverse combs of setae, one anterodorsal setae, two posterodorsal large setae and 2–3 small posterodorsal setae between the two large ones. Hind femur swollen (height/length ratio: 0.43), with ventral setulose lobe near base ( Figs. 41–42 View FIGURES 39 – 42 ). Hind tibia with one anterodorsal and 4–6 posterodorsal setae and 13 transversal combs of setae. Wing. ( Fig. 30 View FIGURES 23 – 30 ) Costa 0.45 of the wing length, R2+3 absent or vestigial, other characteristics as described for the genus. Halter yellowish-brown. Abdomen. Tergites dark brown, with yellow posterior band. Hypopygium yellowish-brown ( Figs. 67–70 View FIGURES 67 – 70 ). Left epandrial process large, ventrally concave, with two apical lobes and subepandrial setose process. Right epandrial margin ventral part not projected posteriorly. Hypandrium bilobed, laterally microtrichose. Hypoproct with two setae.

Etymology. The specific epithet trichopoda refers to the species hind femur setulose lobe and is derived from the Greek roots trichos (hair) and podos (foot).
