Cosmolaelaps chianensis (Gu) (Figures 1–7) Hypoaspis chianensis Gu, 1990: 441. Hypoaspis ( Cosmolaelaps ) hefeiensis Xu & Liang, 1996: 193 (junior synonymy by Ma, 2006: 23; Bai & Ma, 2012: 558). Hypoaspis ( Cosmolaelaps ) hefeiensis .— Bei et al ., 2003: 648. Hypoaspis chianensis .— Ren & Guo, 2008: 329. Cosmolaelaps chianensis .— Moreira et al ., 2014: 319; Keum et al ., 2017: 486. Specimens examined .Ten females and five males, National forest, Sakhalin Island, Russia, 46°57'39"N 142°45'28"E, 9 August 2021, O. Joharchi coll., in the nest of Myrmica sp. (Hymenoptera: Formicidae) (in TUMZ). Remarks . Cosmolaelaps chianensis was described from China (Gu, 1990). 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 . However, Ma (2006) did not provide any explanation for this decision, nor did he provide the details of the examined specimens. Cosmolaelaps hefeiensis was also described from China (Xu & Liang, 1996). It has been found from moss (Xu & Liang, 1996) and this species also has been recorded from soil in Republic of Korea (Keum et al ., 2017) and Russia (Marchenko, 2017). By comparing the descriptions and figures of these two species, we found some distinguishing morphological differences: (1) dorsal shield setae J5 and Z5 more or less similar in length, and j1 considerably shorter than j 2 in C . hefeiensis (see Xu & Liang, 1996 and Fig. 1 of current study), while in C . chianensis setae Z5 are obviously longer than J5 and j1 is similar length to j2 (see Fig. 1 in Gu, 1990); (2) body size 395 long, 255 wide in C . chianensis (see Gu, 1990), while in C . hefeiensis size of body larger, especially its width (484–560 long, 345–391 wide) (see Xu & Liang, 1996). Our efforts to see type material of these two species were not successful so, in this study we follow ...
