Type material. Holotype, female (slide number NJAUAcariEri227, marked Holotype), from Lonicera japonica Thunb. (Caprifoliaceae) , Taibai Mountain, Mei County, Shaanxi Province, P. R. China, 34°01'51' N, 107°48'36' E, elevation 2810m, 1 September 2004, coll. Xiao-Feng Xue & Zi-Wei Song. Paratypes, 6 females and 5 males (slide number NJAUAcariEri227), with the same data as holotype; 8 females (slide number NJAUAcariEri461) from Lonicera japonica Thunb. (Caprifoliaceae) , Guan' egou, Dangchang County, Gansu Province, P. R. China, 33°57'39' N, 104°19'45' E, elevation 2083m, 11 September 2005, coll. Xiao-Feng Xue & Zi-Wei Song.

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

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

Differential diagnosis. This species is similar to Phyllocoptruta sorbarianis Song, Xue & Hong, 2008 , but can be differentiated from the latter by the median line absent from the prodorsal shield (median line present on prodorsal shield in Phyllocoptruta sorbarianis ), dorsal annuli smooth (dorsal annuli with microtubercles in Phyllocoptruta sorbarianis ), coxal plates with short lines (coxal plates I with granules, II smooth in Phyllocoptruta sorbarianis ), and tarsal empodium 7-rayed (tarsal empodium 4-rayed in Phyllocoptruta sorbarianis ).
