The thorax is covered by black hairs, with gray hairs on the sides of breast and abdomen. Head, proboscis and palpi are blackish-brown, whereas legs and halteres are black. The eyes are enormous and contiguous, while in the females they are smaller and clearly separated. The short and robust antennae are inserted under the eyes. Wings are transparent or whitish, but brownish along the costa.
