Diagnosis. This species is similar to Y. umbrina sp. nov., but can be distinguished by the forewing having a white streak extending from the base to the distal 1/5 of the costa and lacking the dot on the fold ( Fig. 39 ), the arched uncus in the male genitalia ( Fig. 139 ), and the Y-shaped lamella postvaginalis in the female genitalia ( Fig. 184 ). In Y. umbrina sp. nov., the forewing has a white streak extending from the base to the 1/2 length of the costa and bears a black dot at middle of the fold ( Fig. 40 ), the male uncus is subulate ( Fig. 140 ), and the female lamella postvaginalis is U-shaped ( Fig. 185 ).
