Ixodes ovatus Neumann, 1899 . An Oriental and Palearctic species whose adult and immature stages have been found on Carnivora : Canidae , Felidae and Ursidae , Lagomorpha : Leporidae and Ochotonidae , and Rodentia : Muridae ; adults alone have been collected from Mammalia (several orders), and Galliformes : Phasianidae ; immature stages alone have been recovered from Carnivora : Mustelidae , Rodentia : Cricetidae , Scandentia : Tupaiidae , Soricomorpha : Soricidae and Talpidae , and Passeriformes : Emberizidae . Ixodes ovatus is a frequent parasite of humans. M: Nuttall (1916) , under the name Ixodes japonensis , a synonym of Ixodes ovatus ; see note below F: Neumann (1899) N: Asanuma and Sekikawa (1952) , under the provisional name Ixodes sp. 52, as explained in Yamaguti et al. (1971) L: Asanuma and Sekikawa (1952) , under the provisional name Ixodes sp. 6, as explained in Yamaguti et al. (1971) Redescriptions M: Yamaguti et al. (1971) , Hoogstraal et al.

Hoogstraal et al. (1973a) state that two or three species may be included under the name Ixodes ovatus , a hypothesis also supported by Li et al. (2018) after molecular analyses of different populations of this tick. The latter authors listed as found in the USA (Nearctic Region) a specimen of Ixodes ovatus used to obtain a 16S gene sequence, but that specimen was actually collected in the Palearctic Region. See also Ixodes succineus (fossil) for its relationship to Ixodes ovatus .
