Huang, Hao & Song, Kui, 2022, A review of the genus Colias Fabricius, 1807 (Lepidoptera: Pieridae) from Qinghai with descriptions of a new subspecies of Colias thrasibulus Fruhstorfer, 1910, Zootaxa 5105 (4), pp. 451-489 : 461-462

Colias thrasibulus fasciata Kocman, 1999

( Figs. 22 , 25 , 42–43 , 45–46 , 48 –50, 57, 67)

Colias montium fasciata Kocman, 1999: 55 , pl. 7, fig. 4 for ♂ holotype (TL: Chiehku, Yushu); Grieshuber et al., 2012: 102, discussions on type series, type locality and taxonomic status, pl. 13, figs. 26–28 for ♂♂.

Colias thrasibulus fasciata: Kocman, 2003: 41 ; Grieshuber, 2014: 39, figs. for ♂ & ♀.

Material examined. CHINA: Qinghai: 6 ♂♂ & 2 ♀♀ ( CSK, CHH, CWCH), on road from Yushu to Qumalai, 3900–4000m, 25.VI.2011 & 13.VII.2019, K. Song leg ..

Remarks. Only 5 ♂♂ (including holotype) and 1 ♀ are known from the literature. The authors figured further 5 ♂♂ and 2 ♀♀ in this work. This subspecies seems to be constantly dark on discal area of hindwing upper side. It is easily separable from the populations of C. thrasibulus thrasibulus Fruhstorfer, 1910 (= C. thrasibulus zanskarensis Hoshiai, 1996 ) from Ladak, Zanskar and W. Tibet. One of the male specimens from Namco area, NC. Tibet ( Hoshiai, 1996: 8 -figs. 31–32; Grieshuber et al., 2012: pl. 13, fig. 25) is intermediate between C. thrasibulus thrasibulus and Colias thrasibulus fasciata .

Flight period. End of June to mid July.

Altitude. 3900–4000m

Distributional notes. The junior author collected this taxon from a locality on the road from Jiegu to Qumalai, he surveyed the vicinity of Jiegu but did not find this butterfly.
