M2 with base unsclerotized; r-m unsclerotized; two basal expansions on gonocoxite, the dorsal side expanded basally, with divergent apex; the ventral side with narrow tip, curved medially; arm of gonocoxite bifurcate with elongated bristles at apex; cercus terminally expanded with two apical setae. Description. Male. Head subcircular in frontal view. Antenna incomplete in the studied specimens; scape subcylindrical; pedicel subspherical; flagellomeres pyriform and eccentric; ascoids 1.25 times as long as the length of flagellomere (Fig. 18A).

R4+5 with base unsclerotized; M2 with base unsclerotized; r-m unsclerotized and m-cu absent (Fig. 18C). Male terminalia: Hypandrium and gonocoxites fused with two basal expansions, the dorsal side expanded basally, with divergent apex; the ventral side with narrow tip, curved medially (Fig. 18D). Arm of gonocoxite bifurcate with elongated bristles (Fig. 18 G). Gonostylus slightly sclerotized, articulated ventrally to gonocoxite, near to the base, bare, subtriangular (Figs. 18D, 18 G).
