Ixodes filippovae Černý, 1961 . Palearctic: 1) Hungary , 2) Kazakhstan , 3) Kyrgyzstan , 4) Ukraine ( Filippova 1958 , Babos 1964 ). Ixodes filippovae is a questionable species proposed by Černý (1961) for nymphs and larvae collected from marmots and described as Ixodes crenulatus by Filippova (1958) , while the first description of the female is in Babos (1964) under the name Ixodes danyi . Ixodes filippovae was treated as a synonym of Ixodes crenulatus in Filippova (1977) and not included as a valid species in the tick lists of Keirans (1992) and Kolonin (2009) , although Camicas et al. (1998) treated Ixodes filippovae as valid under the name Scaphixodes filippovae , and Horak et al. (2002) included Ixodes filippovae in their list of ticks of the world. Guglielmone et al. (2010 b , 2014, 2020) treated Ixodes filippovae as provisionally valid, pending further studies. Consequently, distributional data concerning Ixodes filippovae are tentative. The provisional range of Ixodes filippovae is based on ticks collected from marmots and identified as Ixodes crenulatus by Filippova (1958) and Babos (1964) . The latter author described Ixodes danyi , a species from Hungary that was treated as a synonym of Ixodes filippovae (under the genus Scaphixodes ) by Camicas et al. (1998) , but Hornok et al. (2020a) regarded Ixodes danyi as a synonym of Ixodes canisuga , while Perfilyeva et al. (2020) did not list Ixodes filippovae as a tick found in Kazakhstan .
