Description. Male. Body length, 2.2–2.4 mm. Head. Frons dark brown, pubescent, without median furrow. Flagellomere 1 light brown, pubescent, oval. Arista pre-apical, pubescent. Palpus light brown; one upper genal seta. Thorax. Scutum and scutellum dark brown, pleural sclerites brown; anepisternum setulose dorsally, with one long seta. Legs light brown, except foretibia and foretarsus, yellowish-brown. Forefemur with ventral row of strong setae along its entire extension. Foretibia with one dorsal seta at basal third and an anterodorsal row of strong setae. Foremetatarsus ratio, 4.3. Midtibia with one anterodorsal and three posterodorsal setae ( Fig. 166 View FIGURES 160–195 ). Hind femur swollen (height/length ratio, 0.4), without strong ventral setae. Hind tibia with 1–2 anterodorsal and five posterodorsal setae ( Fig. 203 View FIGURES 196–233 ). Wing. Costa 0.5 of the wing length, other wing features as for the genus. Halter white. Abdomen. Tergites dark brown, with lighter posterior band and dense microtrichia producing a silvery sheen. Hypopygium brown ( Figs. 36–39 View FIGURES 36–39 ). Epandrial medial process with curved projection at right apex bearing one large seta and a sharp projection laterally at the right, near base. Epandrial right posterior margin ventral apex with large, posterior projection, without subepandrial setulose process. Hypandrium lobes elongated, with approximately the same size, left lobe bifurcated near base. Hypoproct with three setae. Phallus ( Figs. 266–267 View FIGURES 264–267 ). Basiphallus without dorsal process. Core plate membranous, with left projection. Epiphallus ending free, with thin, transparent scales. Ventral plate restricted to the right side, long and thin.

Female. Unknown.

Geographic distribution. Nicaragua, Costa Rica, and northern and western Colombia (not in Amazonian Colombia).

Etymology. The specific epithet acrochaetopyga refers to the hypopygial apical seta, and is derived from the Greek roots akros (tip), chaite (long hair, seta) and pyge (rump, buttocks).

Comments. Neopleurophora acrochaetopyga shows great resemblance with N. tanytarsus and N. carcharopyga , especially in the phallic morphology. Neopleurophora acrochaetopyga can be differentiated from these two species by its hypandrium left lobe bifurcated at base.
