. Body very dark brown to black. Longitudinal sensilla usually present on F2–F8 of the female antenna but F2 sometimes lacking sensilla (Fig. 29). Submedial carinae on the propodeum thick, distinct, parallel, almost reaching the dorsellum. Forewing (Fig. 30) hyaline or with a faint uniform brown tinge; microtrichia of blade absent behind venation except for a few setae behind stigmal vein.
