Ypsolopha ulingensis Yang: Ponomarenko & Zinchenko, 2013: 29 [quoted ‘ Figs 6, 7 ’ not from Yang 1977, may be from Sohn 2011, and the type locality is mistakenly written as ‘Lingwushan’. It is Wulingshan]. (as synonym of costibasella Caradja, 1939).

Type locality: China (Hebei).

Redescription: Adult (Fig. 42): Wing expanse 17.0−18.0 mm. Head white, yellow around eyes. Antenna white, ringed with dark brown on each flagellomere. Labial palpus white, basal segment golden on dorsal surface, second golden on outer surface; tuft of second segment triangular, nearly as long as labial palpus; third segment only 1/3 length of second. Thorax white, tinged with yellow. Tegula golden. Forewing with CuA1 and CuA2 separated (Fig. 91); costa gray on basal half, ocherous yellow on distal half; broad golden streak below basal half of costa, not well-defined; fold dark brown on basal 2/3, white on distal 1/3; white stripe extending along basal 2/3 below fold, then arched upward across lower angle of cell reaching below apex, above white stripe yellowish brown mixed with dark brown, below white stripe grayish yellow mixed with brown; cilia grayish brown, mixed with yellow. Hindwing gray, darkened to apex; cilia with basal half grayish brown, distal half yellowish white. Legs white, sprinkled with brown on dorsal surface, grayish brown on tarsi.

Male genitalia (Fig. 142): Uncus being a small arch. Socius slender, pointed slightly at apex. Ventral plate of gnathos narrowly tongue-shaped. Valva ovate, ventral margin concave near base. Saccus about 2/3 length of socius, narrowed on basal 1/4, narrowly rounded at apex. Anellus about a quarter length of phallus, sparsely spinous on distal half. Phallus slender, slightly longer than valva; coecum 1/5 length of phallus; cornuti about 1/3 length of phallus, composed of two rows of microspines.

Female genitalia (Fig. 187): Intersegmental membrane between papilla analis and 8th abdominal segment 1/2 length of abdomen. Apophyses posteriores about twice length of apophyses anteriores. Lamella postvaginalis Vshaped. Antrum parallel-sided laterally. Ductus bursae about 1.25 times length of corpus bursae. Corpus bursae nearly rounded; signum about 2/5 length of corpus bursae, granulous around, ridged at anterior 1/3, narrowed posteriorly.

Distribution. China (Hebei, Shanxi, Sichuan, Qinghai).

Diagnosis. This species is characterized by the forewing having a golden streak below basal half of the costa (Fig. 42). Ypsolopha ulingensis is similar to Y. triangula sp. nov. in facies, but differs in the forewing having a curved white stripe extending along basal 2/3 below the fold and reaching below the apex (Fig. 42), which extends to basal 2/3 length of the fold in the latter species (Fig. 47). It is also similar to Y. capitalba sp. nov. in the male genitalia, but can be separated by the ovate valva and the saccus narrowed on the basal 1/4 (Fig. 142); in Y. capitalba sp. nov., the valva is elongate ovate and the saccus is parallel-sided (Fig. 144).

Ypsolopha ulingensis is more similar to Y. costibasella (Caradja, 1939) in the male genitalia, but differs in the narrower streak along the costa that is longer than half length of the forewing, and the white stripe that extends along basal 2/3 below the fold, then archs upward across the lower angle of the cell, and finally reaches below the apex; and the relatively wider valva and shorter coecum in the male genitalia.

Remarks. Ponomarenko & Zinchenko (2013) synonymized this species with Ypsolopha costibasella (Caradja, 1939) . We treat it as a valid species after having examined the holotype. The adult is redescribed and the female genitalia are described for the first time.
