Diagnosis. Adult ( Fig. 1 ). Wingspan 13.0‒15.0 mm. Thecobathra albana is diagnosed in the male genitalia by the wide subscaphium subparallelly sided and the spatulate ventral plate of the gnathos ( Fig. 11 ); in the female genitalia by the subrectangular lamella postvaginalis and the signum concave in C shape posteriorly ( Fig. 23 ). It is similar to T. acrivalvata Fan, Jin et Li, 2008 in male genitalia, and the differences between them are stated in the diagnosis of the latter species.

Distribution. China (Fujian, Guangxi, Hainan, Jiangxi, Taiwan, Zhejiang).

Remarks. Sohn (2018) described T. minuta from Taiwan, China. We found the morphological characters of T. minuta identical to those of T. albana Liu, 1980 based on the specimens examined during this study. Hence we propose T. minuta should be a synonym of T. albana .
