Arista pre-apical, pubescent. Palpus yellowish-brown; two upper genal and one lower genal setae. Thorax. Scutum and 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 ratio, 4.8. Midtibia with one anterodorsal and one posterodorsal setae at basal fourth ( Fig. 185 View FIGURES 160–195 ). Hind femur not swollen (height/length ratio, 0.39), without ventral, strong setae. Hind tibia with one anterodorsal and 3–4 posterodorsal setae ( Fig. 223 View FIGURES 196–233 ). Wing. Costa 0.5 of the wing length, other wing features as for the genus. Halter yellowish-brown. Abdomen. Tergites dark brown, with yellow posterior band. Tergite 6 about three times longer than other tergites. Hypopygium very large, light brown ( Figs. 116–119 View FIGURES 116–119 ). Epandrial medial process very large, bifurcated into a sclerotized left branch which is itself further bifurcated apically and bearing a thin projection near base, and a rounded right lobe. Epandrial right posterior margin with medial projection and subepandrial setulose process. Hypandrium lobes elongated, pointed and sclerotized, of about same size. Hypoproct with two setae. Phallus ( Figs. 306–307 View FIGURES 304–307 ). Basiphallus with large dorsal process. Core plate flattened, bilobed. Epiphallus with large, transparent scales, connected to the right arm at left lateral of the phallus. Ventral plate well developed, apically bifurcated into the secondary scaled process, covered with large scales and a medial lobe with an adjacent scaled process.

Female. Unknown.

Geographic distribution. Known only from the type-locality in western Ecuador.

Etymology. The specific epithet megalopyga refers to the large epandrial medial process, and is derived from the Greek roots megas (large) and pyge (rump, buttocks).

Section B. Species with epandrial medial process right branch rounded, with anteriorly directed pointed apical edge ( Figs. 120–131 View FIGURES 120–123 View FIGURES 124–127 View FIGURES 128–131 ).
