Palearctic: 1) Afghanistan, 2) Armenia, 3) Belarus, 4) Bulgaria, 5) China (north), 6) Georgia, 7) Germany, 8) Iran, 9) Kazakhstan, 10) Kyrgyzstan, 11) Moldova, 12) Mongolia, 13) Poland, 14) Romania, 15) Russia, 16) Slovakia, 17) Turkey, 18) Ukraine, 19) Uzbekistan (Hoogstraal 1973 a, Filippova 1977, Chen et al. 2010, Bursali et al. 2012, Fedorova 2012, Nowak-Chmura & Siuda 2012, Akramova et al. 2016, Dilbaryan & Hovhannisyan 2016, Karbowiak et al. 2020, Perfilyeva et al. 2020, Sukhiasvhili et al. 2020, Tsapko 2020, Zhao et al. 2021, Li et al. 2022).

Authors such as Černý (1969a) have proposed that the name Ixodes crenulatus should be declared invalid. Emel’yanova (1979, under the name Pholeoixodes crenulatus ) suggested that this taxon represents a species complex, while Filippova & Panova (2000) described several morphotypes of Ixodes crenulatus . Teng & Jiang (1991) and Kolonin (2009) followed Filippova (1977) in considering Ixodes canisuga a synonym of Ixodes crenulatus , but both species are treated as valid here. Petney et al. (2012) stated that several records of Ixodes crenulatus from ex-USSR countries in Pomerantzev (1950) correspond, in fact, to Ixodes hexagonus , although Filippova (1977) supported the opinion of Pomerantzev (1950). It is almost certain that several records of Ixodes crenulatus represent other species, and the range of this tick should therefore be considered provisional.

Hosseini-Chegeni et al. (2019) included Ixodes crenulatus in their list of Iranian ticks, although they stated that new studies are needed to confirm its presence in Iran. Rubel et al. (2021) did not list Ixodes crenulatus as a tick found in Germany, while Petney et al. (2012) doubted its presence there, although recognizing that Ixodes crenulatus was described from ticks collected in Germany, a country that we include within the range of this species.

Le Riche et al. (1974) listed Ixodes crenulatus as found in Cyprus, but this record needs confirmation, and Cyprus is not included here as within the range of this tick.
