The body varies in length between 4 and 5mm and is blackish brown except for the wings, which are colourless. The head is elongate and is arched dorsally. The postocellar setae are smaller than the postocular setae and all setae on the head are pointed. Antennal segment 3 had 1 inner and 1 outer sense cone. The prothorax is transversely striate in places and the metanotum is transversely striate to slightly reticulate. The fore tarsi of females are armed with a small tooth at the inner apex, while the fore tarsi of males are unarmed. Males and females are macropterous and have 26 to 36 accessory fringe cilia per forewing. The wing holding setae are strongly developed, and the tube is long, hairy and bowed.
