Desmometopa nigrifemorata
This species is distinguished from its congeners by the following combination of characters: Both sexes with entirely black and enlarged palpus; forefemur black except for base; mid- and hindfemora black; posteroventral brush on hindtarsus dark.
Male. Predominantly black; forecoxa, base of forefemur, mid- and hindtibiae and mid- and hindtarsi except distal tarsomeres yellow. Palpus black.
Head: Anterior frontal seta half as long as posterior frontal seta. Two setulae between frontal setae. Length of postorbital region not recognizable because of shriveled head. The same holds true for the vibrissal angle.
Wing: Length: 2.5-2.6 mm.
Abdomen: Tergites 1-4 microtrichose and subshiny medially, polished laterally, microtrichose spots progressively decreasing posteriorly; tergite 5 and all sternites polished.
Female. Differs from male in slightly narrower palpus. In female from Uvongo, anterior frontal seta about 3/4x as long as
posterior frontal seta. (Brake & Freidberg 2003)
