Type material. Holotype, female (slide number NJAUAcariEriH34, marked Holotype), from Crataegus maximowiczii Schneid. (Rosaceae) , Huzhong District, Heilongjiang Province, P. R. China, 52°01'44''N, 123°35'44''E, elevation 512m, 22 July 2008, coll. Xiao-Feng Xue, Zhen Wang & Zi-Wei Song. Paratypes, 4 females and 9 males (slide number NJAUAcariEriH34), with the same data as holotype.

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

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

Differential diagnosis. This species is similar to Calepitrimerus crataegi Malandraki, Petanovic and Emmanouel 2004 , from Crataegus monogyna Jacq. (Rosaceae) , but can be differentiated from the latter by the dorsal annuli with granules anteriorly and laterally (dorsal annuli smooth in C. crataegi ) and prodorsal shield with granules (prodorsal shield without granules in C. crataegi ).
