Type material.

Holotype, female (slide number NJAUEri815, marked Holotype), from Spiraea mongolica Maxim. ( Rosaceae ), Beishan National Forest Park, Huzhu County, Qinghai Province, P. R. China, 36°53'35"N, 102°25'56"E, elevation 2610m, 22 July 2007, coll. Xiao-Feng Xue. Paratypes, 7 females and 2 males (slide number NJAUEri815), with the same data as holotype.

Relation to host.

Vagrant on leaf lower surface.

Etymology.

The specific designation beishaniensis is from the place name Beishan National Forest Park, where the new species were collected; feminine in gender.

Differential diagnosis.

This species is similar to Phyllocoptes adalius (Keifer, 1939) from Rosa sp., but can be differentiated from the latter by prodorsal shield front lobe stout (prodorsal shield front lobe pointed in Phyllocoptes adalius ), dorsal opisthosoma annuli smooth (opisthosoma annuli entirely covered with spinuliferous microtubercles in Phyllocoptes adalius ), Coxisternal plates smooth (coxisternal plates with short lines in Phyllocoptes adalius ).
