43. Dermacentor ushakovae Filippova & Panova, 1987 .

Palearctic: 1) Iran, 2) Kazakhstan, 3) Kyrgyzstan, 4) Mongolia, 5) Tajikistan, 6) Turkmenistan ( Filippova 1997, Kolonin 2009, Fedorova 2017).

Dermacentor ushakovae is another member of the Dermacentor marginatus species complex and its validity is not universally accepted. Camicas et al. (1998) regarded Dermacentor ushakovae as a synonym of Dermacentor niveus , while other workers have treated it as a synonym of Dermacentor marginatus .

The geographic distribution of Dermacentor ushakovae is also disputed by several workers, such as Kiefer et al. (2010) and Černý, J. et al. (2019), who did not recognize its presence in Mongolia. Additionally, Dermacentor ushakovae is not listed by Hosseini-Chegeni et al. (2019) as a tick found in Iran. The holotype of Dermacentor ushakovae was collected in Kazakhstan, but Perfilyeva et al. (2020) did not include this tick in the ixodid fauna of that country. We provisionally include Iran, Kazakhstan and Mongolia within the range of Dermacentor ushakovae , but our analysis of this species’ geographic distribution should be considered tentative and subject to reassessment when the relationships among members of the Dermacentor marginatus complex are clarified.
