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.

Type material. Holotype: ♀, China, Mt. Wuling [=Wulingshan. Sohn (2011) mistakenly wrote as ‘Lingwushan’] (40°36′ N, 117°29′ E), Xinglong County, Hebei Province, 1700 m, 22.viii.1973, coll. Jikun Yang [Sohn 2011 mistakenly wrote as “HM Chen”] (examined). Allotype: ♂, same data as for holotype (not examined, possibly missing). Paratype: 1 ♀, same data as for holotype except coll.

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.
