Diagnosis. For differences between C. wanda wanda and C. arida cakana, see under C. arida cakana . For differences between C. wanda wanda and C. adelaidae adelaidae, see under C. adelaidae adelaidae .

Identification. The photos of the type specimens of both Colias wanda and C. baeckeri presented by Grieshuber (2015, 2016a, 2020) on the internet are consulted. One of the male specimens from Tongren area (Fig. 7 - Specimen C27), neighbouring to the type locality of C. wanda, is almost identical with the lectotype of C. wanda in the wing-characters. Male and female specimens from Qilian County are in common with some of the type specimens of C. baeckeri . The authors agree with Grieshuber & Churkin (2003) in synonymizing C. baeckeri with C. wanda, considering the great individual variations in male and the consistence of the wing characters in female. The male specimens from Huashixia area are a little different in the more frequently greenish ground color on hindwing underside, but such difference is not out of the individual variations of C. wanda wanda . The female specimens from Huashixia are in common with the females from the other localities in Qinghai. Specimens from Dulan area are larger than in other populations of C. wanda, often as large as the specimens of C. arida cakana; they are identified as C. wanda wanda on the female characters.

Flight period. Whole July.

Altitude. 3800–4300m.

Distributional notes. The junior author collected 3 ♂♂ from a locality of Tongren (Fig. 68), close to Xiahe, the type locality of C. adelaidae . He also collected a series of specimens from a locality of Dulan (Fig. 68), ca 15 km away from a new locality of C. adelaidae at Dulan.
