Male ( Fig. 39 View FIGURES 39, 40 ) holoptic; scutum faintly greyish pruinescent, with 4 narrow shiny vittae; presutural dc pale 1–2-serial, hair-like, moderately long, acr biserial, similar to but somewhat shorter than dc, laterotergite with pale setae; legs long, very slender, shiny, with strongly reduced setation; hind tibia gently curved inwards beyond middle, hind basitarsus long spindle-shaped, with dense long hair-like setae dorsally; wing faintly infuscate, CuA+CuP almost complete, well sclerotized, disappearing or evanescent just before wing margin, halter yellow; abdomen with shiny dorsum, covered with pale setae; terminalia longer than thorax; epandrium elongate, almost strap-like, somewhat broadly constricted on about middle, with broadly rounded apex; cercus long, but shorter than epandrium, narrow, constricted on about middle; phallus very long, hair-like, without loops, extended beyond epandrium. Female ( Fig. 40 View FIGURES 39, 40 ) wing broad, brownish; hind tibia and tarsus simple; legs without pennate setae.
