General Description
provided by University of Alberta Museums
Male maxillary palps are quite short; the basal articles are fused and the labial palps are thick and twice the length of the maxillary palps. Wings have a dense covering of fine, long hairs (pilosity). The male clasper is linear and held at a 45? angle. The distal article of the clasper is paralleled by an equally long proximal article (located disto-ventrally), each being slightly tapered and rounded distally.
