11. Dermacentor everestianus Hirst, 1926 .

Palearctic: 1) China (north), 2) Nepal (north and central) ( Apanaskevich et al. 2014).

Dermacentor birulai was treated as a valid species in Filippova (1997, 2008) and Kolonin (2009) but regarded as a synonym of Dermacentor everestianus in Camicas et al. (1998), Guglielmone & Nava (2014) and Guglielmone et al. (2014). Apanaskevich et al. (2014) confirmed that Dermacentor birulai is a synonym of Dermacentor everestianus . Another species, Dermacentor abaensis , was regarded as valid by most tick workers, but Apanaskevich et al. (2014) found that it too is a synonym of Dermacentor everestianus . However, Zhang, G. et al. (2019), Zhang, Y.K. et al. (2019) and Zhao et al. (2021) have continued to accept Dermacentor abaensis as a valid tick name.
