Type material. Holotype, female (slide marked NJAUAcariEri879 holotype), from Cunninghamia sp. (Taxodiaceae), Bayi Town, Nyingchi (Linzhi) Prefecture, Tibet Autonomous Region, P. R. China, 14 August 2007, coll. Zi-Wei Song, Xiao-Feng Xue & Zhen Wang. Paratypes, 7 females and 2 males (slides marked NJAUAcariEri879) with the same data as holotype.
Relation to host. Vagrant on leaf undersurface. No damage to the host was observed.
Etymology. The specific designation cunninghamiae is from the host genus name “ Cunninghamia ”.
Differential diagnosis. This species is similar to P. dimidius Huang, 2001, but can be differentiated by the prodorsal shield design with median line complete, submedian lines incomplete, admedian lines sinuous, median and admedian lines connect with a V-shaped line at 1/4 from anterior (prodorsal shield design with median line from base to middle, parallel with median line, with 3 transverse lines at basal 1/4, middle and 3/ 4, submedian lines complete, converging to apex, subparallel with admedian lines in P. dimidius); prosternal apodeme absent (prosternal apodeme present in P. dimidius); and dorsal annuli with tapered microtubercles (dorsal annuli with spiny microtubercles in P. dimidius).
