Holotype , female (slide marked NJAUAcariEri973/974 holotype ), from Smilax sp. ( Liliaceae ), 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 , 18 females and 10 males (slides marked NJAUAcariEri973/974) 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 smilanus from the host genus name “ Smilax ”. Differential diagnosis. This species is similar to P . kuangii Amrine & Stasny, 1994 ( Kuang & Zhuo, 1989 ) , but can be distinguished by the shield design with incomplete median line only present on 1/3 of shield and subparallel with admedian lines; admedian and submedian line separated (shield design with median line connected with submedian lines by two transverse lines at the end of median line; admedian and submedian lines connected by two transverse lines in P . kuangii ); lateral aspect of prodorsal shield smooth (short lines on lateral sides of shield in P . kuangii ).
