Scutellum with 2 more robust bristles. Postpronotum bare. Wing brownish; R 1 = 1/2 R; c somewhat longer than 1/2 w; y = x, both bare; Mfork shorter than M-stem, rather wide; CuA-stem = x; posterior veins distinct, without macrotrichia. Haltere short, brown. Legs yellowish; tibial organ with a small patch of stronger bristles, distinctly bordered. Claws finely toothed. Abdomen: Inner margin of gonocoxites with a few longer bristles between short hairs.
