Description. Male. Body length, 3.2 mm. Head. Frons dark brown, pubescent, without median furrow. Flagellomere 1 light brown, pubescent, oval. Arista pre-apical, pubescent. Palpus yellowish-brown; one upper genal seta. Thorax. Scutum dark brown, pleural sclerites brown; anepisternum setulose dorsally, with one long seta; scutellum dark brown, with medial and posterior areas brown. Legs light brown. Forefemur with ventral row of strong setae along its entire extension. Foretibia with two dorsal setae and an anterodorsal row of strong setae. Foremetatarsus ratio, 4.2. Midtibia with two anterodorsal and 3–4 posterodorsal setae ( Fig. 168 View FIGURES 160–195 ). Hind femur not swollen (height/length ratio, 0.38), without ventral, strong setae. Hind tibia with two anterodorsal and six posterodorsal setae ( Fig. 205 View FIGURES 196–233 ). Wing. Costa 0.52 of the wing length, other wing features as for the genus. Halter dark brown, with ventral white round maculation. Abdomen. Tergites dark brown, with lighter posterior band and dense microtrichia producing a silvery sheen. Hypopygium brown ( Figs. 44–47 View FIGURES 44–47 ). Medial process large, bifurcated at apex into two long curved processes, with right sharp projection close to base. Epandrial right posterior margin with posterior, pointed projection, without subepandrial process. Hypandrium lobes sclerotized; left lobe bifurcated; right lobe pointed. Hypoproct with nine setae. Phallus ( Figs. 270–271 View FIGURES 268–271 ). Basiphallus without dorsal process. Core plate membranous, with left, triangular projection near apex. Epiphallus ending free, with thin, transparent scales. Ventral plate restricted to the right side, short and dorsally serrated.

Female. Unknown.

Geographic distribution. Known only from the type-locality in Colombia.

Etymology. The specific epithet dichaeta refers to the pair of setae on the foretibia, and is derived from the Greek roots di (two) and chaite (long hair, seta).

Comments. Neopleurophora dichaeta is the morphologically most distinct species among the members of the group 3, mainly because of its characteristic long, sclerotized, bifurcated epandrial medial process and the bifurcated hypandrial left lobe.
