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.
