Diagnosis. This species is characterized by the forewing having a white crescent-shaped spot at the lower angle of the cell, the large broadened valva in the male genitalia ( Fig. 133 ), and the ovate signum with one ridge in the female genitalia ( Fig. 179 ). Ypsolopha contractella is similar to Y. cristata Moriuti in the male genitalia, but differs in the inception of the ductus ejacuiatorius placed near the base of the phallus ( Fig. 133 ), which is at 1/3 length of the phallus in the latter species ( Moriuti 1977: Fig. 232).
