Description. Male. Body length, 3.0 mm. Head. Frons dark brown, pubescent, without median furrow. Flagellomere 1 light brown, pubescent, oval. Arista pre-apical, pubescent. Palpus light brown; 1–2 lower genal and 1–2 upper genal setae. Thorax. Scutum dark brown, pleural sclerites brown; anepisternum setulose dorsally, with one long seta; scutellum dark brown, with medial and posterior areas gray. Legs light brown, except foretibia and foretarsus, yellowish-brown. Forefemur with ventral row of four strong setae near apex. Foretibia with one dorsal seta at basal third and an anterodorsal row of strong setae. Foremetatarsus short (length/width ratio, 2.7). Midtibia with one anterodorsal and one posterodorsal seta at basal third ( Fig. 173 View FIGURES 160–195 ). Hind femur swollen (height/length ratio, 0.43), with ventral row of many strong setae near base ( Figs. 236–237 View FIGURES 234–239 ). Hind tibia with one anterodorsal and four posterodorsal setae ( Fig. 210 View FIGURES 196–233 ). Wing. Costa 0.48 of the wing length, other wing features as for the genus. Halter dark brown with orange apical rounded maculation. Abdomen. Tergites dark brown, with lighter posterior band. Hypopygium brown ( Figs. 64–67 View FIGURES 64–67 ). Epandrial medial process trifurcated apically into two small ventrally curved processes and one very long, posteriorly directed process (about twice the epandrium length). Right subepandrial setulose process present. Hypandrium right lobe shorter. Hypoproct with two setae. Phallus ( Figs. 280–281 View FIGURES 280–283 ). Basiphallus without dorsal process. Core plate flattened, bilobed. Epiphallus with thin, transparent scales, connected to the right arm at the left lateral of the phallus. Ventral plate well developed, bifurcated at apex into a pair of long processes. Secondary curved process scaled, connected to the epiphallus.

Female. Unknown.

Geographic distribution. This species has a wide distribution when compared to most of the species of the genus, ranging from Costa Rica and Colombia western coast, to French Guiana and southwest Brazilian Amazonia.

Etymology. The specific epithet dolichopyga   refers to the very long, apical projection of the epandrial medial process and is derived from the Greek roots dolicho (long) and pyge (rump, buttocks).

Comments. Neopleurophora dolichopyga   is the most distinctive species of the Group 5. Besides the characteristic elongated projection of the epandrial medial process, N. dolichopyga   has a different kind of row of strong setae on the hind femur, with numerous thinner strong setae. It is the only species in the Group with the phallic secondary scaled process and ventral plate bifurcated at apex.
