Remarks: The holotype of Ypsolopha hebeiensis Yang has been lost, but a paratype which was photographed in Yang (1977) is still extant. The first author (JCS) checked the paratype and noticed its superficial similarity to Y. leuconotella . Since our dissection of Yang’s type specimens was not allowed, instead, we have examined a topotype which was also identified as Y. hebeiensis by Yang. Based on our examination, we found that Y. hebeiensis is indistinguishable from Y. leuconotella in habitus and genital features (Fig. 13), thus we synonymize them.
