Diagnosis
In the male genitalia Ypsolopha nigrofasciata Yang resembles Ypsolopha yasudai Moriuti, 1977 in the valva bearing a knob at two-thirds of costal margin, a wide rounded excavation between the anterior lobes of the tegumen, medially prominent posterior margin of the uncus and two cornuti of less than one-half the length of the aedeagus.
Ypsolopha nigrofasciata is distinguished by the distinctly constricted median plate of the gnathos with dilated proximal part, the distally conical anterior lobes of the tegumen and the straight basal third of the aedeagus. The forewing is characterized by the longitudinal brown median fascia and the white costal and greyish anal areas (Fig. 3). In Ypsolopha yasudai the median plate of the gnathos has parallel margins, the anterior lobes of the tegumen are broadly rounded distally and the aedeagus is gently arched.
Male genitalia
(Fig. 10). Uncus 0.6 times width of vinculum, with triangular projection on posterior margin; socii long, setose, 2.3 times length of median plate of gnathos, tapering towards pointed apex, slightly sinuous. Gnathos constricted just before dilated part of median plate, median plate 0.4 times width of uncus. Tegumen with rounded emargination between anterior lobes, reaching one-half length of tegumen; anterior lobes distally conical. Valva obovate, rounded distally, widest at distal 1/3, considerably narrowed towards base, with distinct knob on costal margin at 2/3 of valvar length; costa relatively narrow, reaching 1/6 length of valva; saccular area one-half width of costa , reaching apex of valva. Vinculum band–like, arched laterally, narrow saccus with parallel margins, slightly shorter than socii. Aedeagus almost straight in basal third and gently arched at middle; coecum about 1/9 length of aedeagus; two cornuti less than one-half length of aedeagus.
