Palearctic: 1) Afghanistan, 2) Armenia, 3) Azerbaijan, 4) Bulgaria, 5) China (north), 6) Egypt, 7) Georgia, 8) Greece, 9) Hungary, 10) Iran, 11) Israel, 12) Kazakhstan, 13) Kyrgyzstan, 14) Nepal (north and central), 15) Pakistan (west), 16) Romania, 17) Russia, 18) Tajikistan, 19) Turkey, 20) Turkmenistan, 21) Ukraine, 22) Uzbekistan ( Warburton 1927, Feider 1965, Cwilich et al. 1967, Begum et al. 1970, Hoogstraal 1973a, Clifford et al. 1975 a, Filippova 1977, Yu et al. 1997, Coipan et al. 2011, Bursali et al. 2012, Fedorova 2012, Mihalca et al. 2012, Akramova et al. 2016, Dilbaryan & Hovhannisyan 2016, Tsapko 2017, Perfilyeva et al. 2020).

As stated under Ixodes acuminatus , several authors have treated Ixodes redikorzevi as a synonym of Ixodes acuminatus , but both species are considered provisionally valid here. There are some records of Ixodes redikorzevi published under the names Ixodes diversicoxalis , Ixodes theodori , Ixodes transcaucasicus and Ixodes transcaucasicus hystrix , all synonyms of Ixodes redikorzevi in Guglielmone & Nava (2014), but Camicas et al. (1998) listed those three names as synonyms of Ixodes acuminatus .

The geographic distribution of Ixodes redikorzevi is vast and unclear ( Guglielmone & Robbins 2018) and mainly based on a study by Filippova (1977). The presence of Ixodes redikorzevi in China is based on Yu et al. (1997). Hosseini-Chegeni et al. (2019) listed this tick as found in Iran but cautioned that its presence in that country needs to be reviewed, while Hornok et al. (2020a) considered Ixodes redikorzevi a synonym of Ixodes acuminatus and did not recognize Hungary as being within the range of Ixodes redikorzevi . Clifford et al. (1975a) classified larvae and nymphs collected in Nepal as Ixodes redikorzevi or a species morphologically close to it. In broad terms, Ixodes redikorzevi is treated as present in the eastern Palearctic, while Ixodes acuminatus is considered to occur in the western Palearctic.
