Type material. Holotype, female (slide number NJAUAcariEriH52, marked Holotype), from Spiraea flexuosa Fisch. ex Cambess. (Rosaceae) , Yichun City, Heilongjiang Province, P. R. China, 47°43'36''N,

Relation to host. Vagrant on leaf surface. No damage to the host was observed. Etymology. The specific designation flexuosus is from the species name of the host plant, flexuosa . Differential diagnosis. This species is similar to Calepitrimerus cotoneaster Song, Xue & Hong, 2009 , from Cotoneaster buxifolia Lindl. ( Rosaceae ), but can be differentiated from the latter by median and submedian lines present on prodorsal shield (median and submedian lines absent in C. cotoneaster ) and prosternal apodeme present (prosternal apodeme absent in C. cotoneaster ).
