L, lateral view of female; CGM, coxae and genitalia of male; L1, leg I; L2, leg II. Type material. Holotype , female (slide marked NJAUAcariEri952 holotype ), from Spiraea myrtilloides Rehd. (Rosaceae) , Bayi Town, Nyingchi (Linzhi) Prefecture, Tibet Autonomous Region, P. R. China , 18 August , 2007, coll. Zi-Wei Song, Xiao-Feng Xue & Zhen Wang. Paratypes , 15 females and 10 males (slides marked NJAUAcariEri952) with the same data as holotype . Relation to host. Vagrant on leaf undersurface. No damage to the host was observed. Etymology. The specific designation myrtilloidia is from the host species name “ myrtilloides ”. Differential diagnosis. This species is similar to P. gracilis ( Nalepa, 1890 ) , but can be differentiated by the dorsal annuli with elliptical microtubercles (dorsal annuli with round microtubercles in P. gracilis ); coxal plates with short lines and granules (coxal plates with fine granules in P. gracilis ); tarsal empodium 7-rayed, solenidion tapered (tarsal empodium 5-rayed, solenidion slightly knobbed in P. gracilis ).
