Cerci as long as hypoproct. Hypoproct microtrichia-covered, covered with spiniform microtrichia ventrobasally, with two lateral, cylindrical lobes with spiniform microtrichia throughout, continuing as a dorsoventrally flattened, apically bilobed lamella, with deep and narrow emargination and a prominent seta on each lobe. Hypoproct about three-quarters length of aedeagus. Mediobasal lobe of gonocoxite divided above base, elongated, cylindrical, thin, apex bearing several setae, microtri- chose throughout. Ventral projection of mediobasal lobe about three-quarters length of aedeagus; dorsal projection about three-quarters length of ventral one.

The specific name should be treated as a noun in apposition.
