Unlike Chiloporter: Labrum [widened see Ameletopsis/fg1 (1)] is semicircular, without median incision; glossae are flat; body form is close to siphlonuroid [if not take into account strongly enlarged specialized head see Ameletopsis/fg1 (1)]; femora are thin, claws are slightly curved, without denticles; last abdominal segments with posterolateral spines. Unlike Mirawara, gonostylus with 2 distal segments.
