Type material. Holotype, female (slide number NJAUAcariEriH70, marked Holotype), from Sambucus williamsii Hance ( Caprifoliaceae ), Harbin City, Heilongjiang Province, P. R. China, 26 July 2008, coll. Xiao-Feng Xue, Zhen Wang & Zi-Wei Song. Paratypes, 8 females and 3 males (slide number NJAUAcariEriH70), with the same data as holotype .

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

Etymology. The specific designation sambucus is from the generic name of the host plant, Sambucus.

Differential diagnosis. This species is similar to Epitrimerus lonicerae Xue, Song & Hong, 2007b , from Lonicera sp. (Caprifoliaceae) , but can be differentiated from the latter by the dorsal annuli with microtubercles (dorsal annuli smooth in E. lonicerae ) and median and submedian lines present (median and submedian lines absent in E. lonicerae ).
