Type material. Holotype, female (slide number NJAUAcariEri376-3, marked Holotype), from Cyclobalanopsis glauca (Fagaceae) , Maoping town, Yang County, Shaanxi Province, P. R. China, 33°31'08" N, 107°40'14" E, elevation 898m, 11 August 2005, coll. Zi-Wei Song and Xiao-Feng Xue. Paratypes, 8 females and 2 males (slide number NJAUAcariEri376-3) with the same data as holotype, occurred together with Paracaliphytoptus yangensis sp. nov. and Cereusacarus maopingensis sp. nov.

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

Etymology. The specific designation glaucaer is from the species name of the host plant, glauca .
