This genus of Tipulidae has a spiracular disk with 4 lobes fringed with long hair. Out of the other end, simple, non-jointed mandible project even when the head is retracted (pictured in the lower left area of the main image). The head, which can be viewed by cutting away the skin, is not extensively sclerotized. Rather, the sclerites are long, slender rods.
