Type material. Holotype, female (slide number NJAUAcariEriH7, marked Holotype), from Cunninghamia sp. (Taxodiaceae) , Jiagedaqi, Heilongjiang Province, P. R. China, 50°24'27''N, 124°06'43''E, elevation 365m, 17 July 2008, coll. Xiao-Feng Xue, Zhen Wang & Zi-Wei Song. Paratypes, 3 females and 9 males (slide number NJAUAcariEriH7), with the same data as holotype.

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

Etymology. The specific designation jiagedaqiensis is from the name of location, Jiagedaqi, where the new species were collected.

Differential diagnosis. This species is similar to Phyllocoptes mediotransversus Huang, 2001b , from Cryptomeria japonica (L. f) D. Don ( Taxodiaceae ), but can be differentiated from the latter by the prodorsal shield with many short lines (prodorsal shield without many short lines in P. mediotransversus ) and coxal plates with granules (coxal plates smooth in P. mediotransversus ).
