description: Kuangella eurycorymbus n. sp.
(Fig. 1)
TYPE MATERIAL. — Holotype: Bubeng, Mengla County (21°30’N, 101°28’E), Yunnan Province, China, 28.XI.2007, from Eurycorymbus cavaleriei (Levl.) Rehd.& Hand.(Sapindaceae), Guo-Quan Wang, slide-mounted, ♀ (DPPGXU).
Paratypes: mounted on 7 slides, with the same data as holotype, 5 ♀♀ (DPPGXU), 2 ♀♀ (MNHN-Ac1179, Ac1180).
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 generic name of the type host plant.
DIAGNOSIS. — Body fusiform, white, prodorsal shield with median and admedian lines complete, submedian lines connected basally forming U-shape; coxal plate with granules; tarsal empodium 5-rayed, tarsal solenidion knobbed; dorsal annuli smooth,ventral annuli with elongated microtubercles; setae h1 absent; female coverflap with granules.

REMARKS
The new species is close to K. theae Wei, Wang & Li, 2009, but can be separated from the latter by the median and submedian lines present, prodorsal shield not sculptured with granules, empodium 5-rayed and infesting Eurycorymbus cavaleriei (Sapindaceae); in K. theae, the median and submedian lines absent, prodorsal shield sculptured with granules, empodium 6-rayed and infesting Sageretia thea (Osbeck) Johnst (Rhamnaceae) (Wei et al. 2009). The new species is differentiated from another species, Kuangella rhis Wei & Qin, 2002, as follows: the submedian lines connected basally forming U-shape, coxisternal plates and female coverflap sculptured with granules and tarsal solenidion placed laterally, knobbed; in K. rhis, submedian lines faint and companied with many granules, coxisternal plates and female coverflap smooth and tarsal solenidion placed normal, unknobbed (Wei & Qin 2002).
