C o m m e n t s: These are the first records of Q. stouraci from Shaanxi. The species was previously known only from the male holotype taken at Heimahe in Qinghai.

Nothing is known at present about the habitat requirements of the species.

The female of the species was not known, the description therefore follows: first four segments of front tarsus similar to those of male, but less dilated, segment two vaguely wider than apex of tibia (ratio 1.1). (First four segments of male front tarsus are markedly dilated, almost patellate, with segment two markedly wider than apex of tibia, ratio 1.35). Genital segment with tergite 10 relatively long, with differentiated, narrow apical portion with two long, strong setae at apex, otherwise very sparingly setose ( Fig. 44 ).
