Type material. Holotype, female (slide number NJAUAcariEriH47-1, marked Holotype), from Acer sp. (Aceraceae) , 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. Paratypes, 4 females and 4 males (slide number NJAUAcariEriH47-1), with the same data as holotype.

Additonal material. 4 females and 2 males (slide number NJAUAcariEri607), from Acer sp. (Aceraceae) , Jingbo Lake , Mudanjiang City, Heilongjiang Province, P. R. China, 44°02'33''N, 128°56'35''E, elevation 376m, 29 June 2006, 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 jingboicus is from the name of location, Jingbo Lake, where the new species were collected.

Differential diagnosis. This species is similar to Shevtchenkella acer Wei, Wang & Qin, 2009 , from Acer davidii Franch. (Aceraceae) , but can be differentiated from the latter by lacking longitudinal lines between the admedian lines on the prodorsal shield (longitudinal lines present between admedian lines in S. acer ), coxal plates I with granules, coxal plates II smooth (coxal plates with short lines in S. acer ) and female genital coverflap with 10 ridges (female genital coverflap with 17 ridges in S. acer ).
