Type material. Holotype, female (slide marked NJAUAcariEri963 holotype), from Deutzia sp. ( Saxifragaceae ), Pai Town, Nyingchi Prefecture, Tibet Autonomous Region, P. R. China (29°35΄10ʺN, 94°55΄44ʺE; H: 3173m), 18 August, 2007, coll. Zi-Wei Song, Xiao-Feng Xue & Zhen Wang. Paratypes, 14 females and 6 males (slides marked NJAUAcariEri963) with the same data as holotype.

Relation to host. Vagrant on leaf undersurface. No damage to the host was observed.

Etymology. The specific designation is deutzianus from the host genus name “ Deutzia ”.

Differential diagnosis. This species is similar to P. spiraeanis Song, Xue & Hong, 2008 a, but can be distinguished by the admedian lines separated, submedian lines connected at posterior; all lines smooth (admedian lines subparallel and connected at rear, all lines with granules in P. spiraeanis ); empodium 4-rayed, tarsal solenidion knobbed (empodium 9-rayed, tarsal solenidion tapered in P. spiraeanis ); ventral annuli with round microtubercles (ventral annuli with elliptical microtubercles in P. spiraeanis ).
