( Figs. 27A –H)

Diagnosis. M2 not reaching M1; bifurcated basal expansion on gonocoxite; two pairs of arms of gonocoxite, the dorsal larger and broader than the ventral, both with bristles; ejaculatory apodeme 0.8 times the length of gonostylus; cercus with an elongated projection with two apical bristles.

Description. Male. Head subcircular in frontal view. Antenna with 13 flagellomeres; cylindrical scape; subquadrangular pedicel; basal flagellomeres pyriform and eccentric ( Fig. 27A ); ascoids 1.2 times as long as a flagellomere; 13th flagellomere subcylindrical with terminal apiculus separated by a suture ( Fig. 27F ). Palpus three segmented; first segment with sensilla in depressed pit on medial surface; palpus formula 1.0:0.6:0.5 ( Fig. 27B ). Wing. M2 not reaching M1; R4+5 incomplete at base; r-m and m-cu absent ( Fig. 27C ). Male terminalia: Hypandrium and gonocoxites fused with bifurcated basal expansion and lateroposterior bristles. Two pairs of arms of gonocoxites, the dorsal larger and broader than the ventral and both with bristles ( Figs. 27D, 27 H). Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, bare, truncated. Aedeagal complex with one pair of Hshaped fused projections. Aedeagus ending at midline of projections in the aedeagal complex ( Fig. 27 H). Ejaculatory apodeme 0.8 times the length of gonostylus. Epandrium longer than wide, subcircular. Cercus digitiform with an elongated projection with two apical bristles ( Figs. 27D, 27E, 27G ). Hypoproct with apical setulae ( Fig. 27G ).

Female. Unknown.
