Description

Forewing (Fig. 3) with distinct dark spot on 3rd apical cell.
Head (Fig. 1) acutely produced medially, about as wide as greatest width of pronotum; coronal suture prominent. Forewing (Fig. 3) with 1st apical cell short. Hind wing (Fig. 11) with submarginal vein confluent with Cu1 markedly distad of point of fusion of Cu1 with M3+4.
Male pygofer (Fig. 5) with short process on lateroventral margin and numerous long macrosetae on posterodorsal surface. Subgenital plate usually forming a pocket-like structure at tip or tapering towards apex (Fig. 6). Style (Fig. 7) broadened and truncate at base. Aedeagal shaft (Figs 8, 9) usually curved dorsally; preatrium long or short; dorsal apodeme narrow. Connective (Fig. 10) V- or Y-shaped; lateral arms long; central lobe absent.

Distribution
