13-14mm, Externally this species resembles lobativalva, except the medial band of the forewing is slightly narrower over the posterior half, and the anterior oblique section of the postmedial has a slight tooth distad at the angle with the central stepped section. The reniform tends to be more untidy, with a more extensive whitish area amongst the dark markings. The male genitalia differ from those of the momusalis trio in having the valves much narrower, tapering apically, acute and upturned, and with an obtusely angled inner saccular margin. The aedeagus vesica is extended laterally on both sides of the aedeagus apex, but the inflated section on the side of the ductus ejaculatorius is longer than that on the ‘scobinate’ side, and this scobination is somewhat coarser. The features of possible females are described under momusalis above.
