Remarks. This species was only recorded from eastern Xizang (Gongjue, Xiongsong), which is 50 kilometers from the border of western Sichuan ( Keith 2008). In this study, two specimens were collected from western Sichuan (400 km from the type locality) by the second author, suggesting a wider distribution in Sichuan ( Fig. 44 ).
