( Figs. 36A–E )

Diagnosis. R4+5,M2 and Sc with tip unsclerotized; r-m and sc-r unsclerotized; two pairs of expansion on gonocoxite, one bifurcated and basal and other reduced with two elongate apical bristles; curved expansion on gonocoxite, spur-shaped, sclerotized apically; one pair of elongated subtriangular projections in the aedeagal complex directed to the apex; ejaculatory apodeme twice as long as a gonostylus; cercus with two apical setae with curved tips.

Description. Male. Head subcircular in frontal view. Antenna incomplete in the studied specimens; scape and pedicel subcylindrical; basal flagellomeres pyriform ( Fig. 36A ); ascoids lost in the specimen studied. Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.6:0.8 ( Fig. 36B ). Wing. R4+5, M2 and Sc with tip unsclerotized; r-m and sc-r unsclerotized; and m-cu absent ( Fig. 36C ). Male terminalia: Hypandrium and gonocoxites fused with two pairs of expansion, one bifurcated and basal and the other reduced with two elongated apical bristles. Arm of gonocoxites with a curved expansion spur-shaped, sclerotized apically, and with basal elongated bristles. Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, bare, truncated. Presence of one pair of elongated subtriangular projections in the aedeagal complex directed to the apex. Aedeagus ending above of projections in the aedeagal complex ( Fig. 36E ). Ejaculatory apodeme long, twice the length of gonostylus. Epandrium lost in the specimen studied. Cercus pilose, piriform with two apical setae with curved tip.
