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 .
