Tachydromia sp.
This single female is closely related to T. terricoloides Shamshev & Grootaert, 2005, but because the male is unknown, we did not name it. The antennae are completely yellow and the basal segments are not darkened as in T. terricoloides . It has a black thorax instead of the yellowish-brown thorax in T. terricoloides . There is a pair of pale dorsocentrals near the middle of the mesonotum that are longer than the other dorsocentrals. The halter has a black knob rather than a yellow knob. The legs are completely yellow including all coxae, but tip of fore tarsomere 1 is ventrally brown, fore tarsomeres 2 and 3 are clear yellow, tip of tarsomere 4 and apical half of tarsomere 5 brown. Tips of mid and hind tarsomeres 4 and 5 brown.
