Type material. Holotype, female (slide marked NJAUAcariEri949 holotype), from Rhododendron sp. ( Ericaceae ), 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, 10 females and 1 male (slides marked NJAUAcariEri949) with the same data as holotype.

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

Etymology. The specific designation painus is from the location of the species be found “Pai Town”.

Differential diagnosis. This species is similar to C. brevilinea Huang, 2001 , but can be distinguished by dorsal shield design with median line absent, many dots on the shield except between admedian and submedian lines (dorsal shield design with median line complete, many short lines on the shield in C. brevilinea ); empodium 4-rayed, coxal plates with short lines (empodium 7-rayed, coxal plates smooth in C. brevilinea ); female genital coverflap with 10 longitudinal ridges (female genital coverflap with 13 longitudinal ridges in C. brevilinea ).
