( Figs 19 , 70 , 119 , 167 )

Ypsolopha acerella Ponomarenko, Sohn et Zinchenko, 2011: 21 .

Type locality: Korea (Gyonggi; Gangwon), Rusia (Primorskii krai, Far East).

Adult ( Fig. 19 ): Wing expanse 23.0−25.0 mm. Forewing with R4 and R5 separated ( Fig. 70 ).

Material examined. 3 ♂♂, 2 ♀♀, Mt. Liupan (35°42′ N, 106°11′ E), Ningxia Hui Autonomous Region, 1900 m, 27.vi.2008, coll. Shulian Hao & Zhiwei Zhang, genitalia slide No. JQ08021♂.

Diagnosis. This species is characterized by the forewing having a rectangular black patch of erect scales beyond middle of the dorsum ( Fig. 19 ). Ypsolopha acerella is similar to Y. yangi Ponomarenko et Sohn superficially, but can be separated by the forewing without rows of ocherous brown scales on the distal 2/3. Ypsolopha acerella is also similar to Y. parallela (Caradja) in the male genitalia, but can be distinguished by the slender coecum that is about 1/3 length of the phallus ( Fig. 119 ), which is 1/6 length of the phallus in the latter ( Fig. 112 ). The female genitalia of this species are characterized by the specific lamella postvaginalis being a long band with rounded posterior margin ( Fig. 167 ).

Host plant. Sapindaceae : Acer ginnala Maxim. ( Ponomarenko et al. 2011) .

Distribution. China (Ningxia), Korea, Russia (Far East).

Remarks. This species is newly recorded for China.
