(Figs 7, 58, 158)
Ypsolophus hebeiensis Yang, 1977: 103; Sohn, 2011: 226. Ypsolopha leuconotellus (Snellen): Sohn et al., 2010: 32. Type locality: China (Bejing, Hebei).
Redescription. Adult (Fig. 7): Wing expanse 17.5 mm. Head white, brown laterally. Labial palpus white, dark brown on outer side of second segment; tuft of second segment triangular; third segment longer than second. Thorax white. Tegula dark brown. Forewing with R4 and R5 separated (Fig. 58); brown except grayish brown on distal 1/3, dark brown along fold, forming a broad longitudinal dark band; dorsal band broad, grayish white, sinuate on upper margin; cilia grayish brown. Hindwing and cilia grayish brown. Fore- and midlegs brown; hindleg yellowish white, grayish brown ringed with white on each tarsomere.
Female genitalia (Fig. 158): Lamella postvaginalis trapezoid, distal 1/3 triangularly concave at middle on posterior margin. Antrum short, cup-shaped. Ductus bursae shorter than corpus bursae, broadened gradually from inception of ductus seminalis to corpus bursae, sparsely granulous just before inception of ductus seminalis. Corpus bursae ovate; signum about 1/3 length of corpus bursae, ridged at anterior 1/4 and posterior 1/5 respectively, anterior half rounded.
Type material. Holotype: ♀, China, Yanshi, Xinglong County (40°24′ N, 117°30′ E), Hebei Province, 29.viii.1973, coll. Jikun Yang (missing). Paratype: 1 ♀, Xiaolongmen, Mentougou, Beijing (39°55′ N, 116°24′ E), 5.ix.1976, coll. Heming Chen [Sohn 2011 mistakenly wrote as “CK Yang”], slide No. JQ08217 (CAU) [examined].
Distribution. China (Beijing, Hebei).
Diagnosis. This species is similar to Y. leuconotella (Snellen), but differs in the forewing grayish brown on the distal 1/3 and having a grayish white dorsal band (Fig. 7), and the signum just about 1/3 length of the corpus bursae in the female genitalia (Fig. 158). In Y. leuconotella (Snellen), the forewing is grayish white with ocherous yellow strips along veins on the distal 1/3 and has a white streak along the dorsum (Fig. 8), and the signum is half length of the corpus bursae in the female genitalia (Fig. 159).
Remarks. Yang described Y. hebeiensis based on two female specimens. Sohn et al. (2010) synonymized Y. hebeiensis with Y. leuconotella (Snellen) based on the superficial characters of the paratype. However, we regard Y. hebeiensis as a valid species after checking and dissecting the paratype. The figures of this species that we have provided here are based on the specimens in our collection since the antennae of the paratype are missing and the female genitalia are somewhat damaged. The adult of this species is redescribed, and the female genitalia are described for the first time.
