Type material. Holotype, female (slide number NJAUAcariEriH62, marked Holotype), from Sorbaria sorbifolia (L.) A.Braun ( Rosaceae ), Harbin City, Heilongjiang Province, P. R. China, 26 July 2008, coll. Xiao-Feng Xue, Zhen Wang & Zi-Wei Song. Paratypes, 11 females (slide number NJAUAcariEriH62), with the same data as holotype.

Additional material. 15 females (slide number NJAUAcariEriH45), from Sorbaria sorbifolia (L.) A.Braun ( Rosaceae ), Yichun City, Heilongjiang Province, P. R. China, 47°43'36''N, 128°55'12''E, elevation 234m, 25 July 2008, coll. Xiao-Feng Xue, Zhen Wang & Zi-Wei Song; 5 females (slide number NJAUAcariEriH24), from Spiraea salicifolia L. ( Rosaceae ), 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.

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

Etymology. The specific designation yichunensis is from the name of the location, Yichun City, where the new species was collected.

Differential diagnosis. This species is similar to Calepitrimerus rubi Lin & Kuang, 2001b , from Rubus parvifolius L. ( Rosaceae ), but can be differentiated from the latter by the dorsal ridges with granules (dorsal annuli smooth in C. rubi ) and median and admedian lines connected (median and admedian lines separated in C. rubi ).
