It has been found associated with Mus pahari Thomas (Rodentia: Muridae). The description of this species is brief and both the description and illustrations lack many important details. Ma (2006) considered that Cosmolaelaps hefeiensis is a junior synonym of C. chianensis. C. hefeiensis was also described from China (Xu & Liang, 1996). It has been found from moss (Xu & Liang, 1996) and is now recorded in Republic of Korea for the first time, from soil. Our concept of the species is based on that of Xu & Liang (1996) and our specimens agree very well with the description given by Xu & Liang, 1996 for Cosmolaelaps hefeiensis. The species is easily recognised by the long and thick setae of the dorsal shield (most setae long enough to reach well past the base of next posterior seta), j1, z1 and Z5 simple and a without knob at their bases and fixed digit of chelicera of female with six teeth.
