TYPE MATERIAL. — Holotype: Fengyangshan National Nature Reserve, Longquan City (27°53’N, 119°11’E), Zhejiang Province, China, 28.VII.2007, from Castanopsis eyrei (Champ.) Tutch. (Fagaceae) , Guo-Quan Wang, slide-mounted, ♀ ( DPPGXU).

RELATION TO HOST. — The mites are vagrant on the undersurface of the leaves, no visible damage seen.
ETYMOLOGY. — The specific designation is derived from the specific name of the type host plant.

REMARKS
The new species is close to D. cylindrokeluphae Wei, Xie & Chen, 2006 , but can be separated from the latter by the submedian lines complete, setae h1 absent and infesting Castanopsis eyrei (Fagaceae) ; in D. cylindrokeluphae , submedian lines incomplete, setae h1 present and infesting Cylindrokelupha robinsonii (Gagnep.) Kosterm (Leguminosae) ( Wei et al. 2006). The species is differentiated from Disella itea n. sp. as follows: anterior prodorsal shield with first eight cells and second six cells, submedian lines complete and basal female coverflap with short irregular lines; in D. itea n. sp., anterior prodorsal shield with first and second two cells, submedian lines absent and female coverflap with granules.
