Description. Male. Body length, 2.1–2.6 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 and pleural sclerites brown; anepisternum setulose, with one long seta; scutellum dark brown, with medial and posterior areas brown. Legs light brown, except foretibia and foretarsus, yellowish-brown. Forefemur with ventral row of medium size setae in its entire extension. Foretibia with one dorsal seta at basal third and an anterodorsal row of strong setae. Foremetatarsus short (length/width ratio, 3.2). Midtibia with one anterodorsal and 2–3 posterodorsal setae ( Fig. 164 View FIGURES 160–195 ). Hind femur not swollen (height/length ratio, 0.38), without ventral, strong setae. Hind tibia with one anterodorsal and 4–5 posterodorsal setae ( Fig. 200 View FIGURES 196–233 ). Wing. Costa about half of the wing length, other wing features as for the genus. Halter gray with a rounded, apical black maculation. Abdomen. Tergites dark brown, with lighter posterior band, and dense microtrichia producing a silvery sheen. Hypopygium light brown ( Figs. 24–27 View FIGURES 24–27 ). Epandrial medial process approximately square, with two pointed apical edges. Epandrial right posterior margin folded and projected medio-posteriorly, without subepandrial setulose process. Hypandrium left lobe strongly sclerotized, pointed; right lobe of medium size. Hypoproct with five setae. Phallus ( Figs. 260–261 View FIGURES 260–263 ). Basiphallus without dorsal process. Core plate membranous. Epiphallus ending free, covered with thin, transparent scales. Ventral plate restricted to the right side, bifurcated into a pair of thin extensions, one dorsal, flattened and one ventral, curved.

Female. Unknown.

Geographic distribution. Amazonian southern Colombia, Amazonian Ecuador, northern Brazil, and French Guiana.

Etymology. The specific epithet microssoma   refers to the small size of this fly, and is derived from the Greek roots mikros (small) and soma (body).

Comments. Neopleurophora microssoma   can be most easily differentiated from N. prionotopyga   by its approximately square epandrial medial process, with two pointed apical edges and its strongly sclerotized hypandrial left lobe.
