Diagnosis. Adult wingspan 7.0−9.5 mm. This species is distinguished by a whitish forewing irregularly marked with light brown at the middle, at the apex, and along the fold. The forewing lacks a black apical spot and a distal patch ( Fig. 46 ). Tenupalpa angustella is somewhat similar to T. nephodesma , but it lacks a transverse fascia on the forewing present in the latter. In the male genitalia, the anellus lobes are strongly developed and bear a robust spinelike bristle. Also, the triangular projection of the juxta, the large saccus, and the long distal part of the aedeagus are diagnostic ( Fig. 5 ). The female genitalia are characterized by a deeply incised posterior margin and a short emarginate anterior margin of tergum VIII, and a small semilunar signum ( Fig. 85 ).

Distribution. China (Beijing, Fujian, Gansu, Guizhou, Henan, Hubei, Jiangxi, Liaoning, Shandong, Zhejiang), Japan, Korea, Russia. This species is newly recorded from China and Korea.

Host plants. Fagaceae : Quercus dentata ( Kyaw et al. 2019) , Q. mongolica ( Omelko 1999; Park & Ponomarenko 2007; Sakamaki 2013; Kyaw et al. 2019).

Remarks. The type materials deposited in ZIRAS of Russia were not examined in this study. A detailed redescription of T. angustella was provided in Kyaw et al. (2019). The male genitalia are sometimes exposed and the morphological features can be observed without dissection ( Fig. 3 ).
