Colias felderi Grum-Grshimailo, 1891: 448 (TL: Myn-da-sha Valley, Laji Shan: Grieshuber et al., 2012); Grieshuber, 2016a: photos of syntypes.

Material examined. None.

Remarks. This mysterious species has not been re-discovered by any Chinese collectors. The female specimen figured and recorded by Chou et al. (2001: figs. 3–4) from Xining, Qinghai, collected by Wei-Bang Xu in August 1990, is merely a misidentification of C. lada .
