Bamboosiella brevibristla Sha, Guo, Feng & Duan, 2003: 244 . Syn. n.

Described originally from Bangkok, Thailand on grass, this species is recorded from Taiwan and Japan by Okajima (1995a). In the present study the holotype and the only female paratype of Bamboosiella brevibristla from Zhejiang Province in China were studied. The original description of that species indicated that the short and expanded pronotal midlateral setae were much shorter than the anteroangulars, and this was considered as a special character differing from other Chinese Bamboosiella species. However, the only remaining anteroangular seta is clearly as long as the only midlateral seta on the holotype, although both types are poorly prepared ( Figs 65–66 ). The other characters such as body colour distribution ( Figs 65–66 ) and postocular setae recorded for brevibristla do not differ from exastis identified based on the original description and the redescription by Okajima (2006).
