168. Ixodes nipponensis Kitaoka & Saito, 1967 .

Palearctic: 1) China (north), 2) Japan (except the Ryukyu Islands), 3) South Korea, 4) Russia ( Filippova 1977, Takada et al. 1998, Robbins 2005, Kolonin 2009, Kim et al. 2011a, Tsapko 2020, Seo et al. 2021).

Yamaguti et al. (1971) cautioned that Ixodes nipponensis can be confused with Ixodes persulcatus and Ixodes ricinus .

Takada et al. (1998) found Ixodes nipponensis in the Palearctic portion of China (Liaoning Province), but this was not recognized by Kolonin (2009), Chen et al. (2010) and Zhang, Y.K. et al. (2019). However, Cheng et al. (2018), Zhang, G. et al. (2019) and Zhao et al. (2021) accepted Liaoning Province as being within the range of Ixodes nipponensis , and northern China is therefore included here.

. Robbins (2005) stated that the presence of Ixodes nipponensis in Taiwan might be due to introduced specimens, while Kuo et al. (2017) collected this tick on migratory birds in Taiwan. Nevertheless, Chen et al. (2010), Zhang, G. et al. (2019), Zhang, Y.K. et al. (2019) and Zhao et al. (2021) included Taiwan within the range of Ixodes nipponensis . Cheng et al. (2018) reported this tick in southern China (Oriental), but its presence there was not recognized by Zhang, G. et al. (2019), Zhang, Y.K. et al. (2019) and Zhao et al. (2021). Taiwan and China (south) are here provisionally excluded from the range of Ixodes nipponensis .
