Haemaphysalis phasiana Saito, Hoogstraal & Wassef, 1974 . Oriental: 1) China (south), 2) Taiwan ; Palearctic: 1) Japan (except the Ryuku Islands), 2) Russia , 3) South Korea , 4) Turkmenistan ( Saito et al. 1974 , Bolotin 1982 , Sames et al. 2008 , Chen et al. 2010 , Zhang, G. et al. 2019, Zhang K.Y. et al. 2019, Tsapko et al. 2020 ). Kolonin (2009) treated Haemaphysalis phasiana as a synonym of Haemaphysalis doenitzi , but other workers have regarded this tick as valid, although recognizing that morphological separation of both species is difficult, while Sames et al. (2008) hypothesized that more than one taxon may exist under the name Haemaphysalis phasiana . See also Haemaphysalis doenitzi , where this problem is further discussed. Saito et al. (1974) regarded their diagnosis of a specimen of Haemaphysalis phasiana from Turkmenistan as tentative, while the presence of this tick in Taiwan is uncertain ( Saito et al. 1974 , Robbins 2005 , Kuo et al. 2017 ); consequently, both Taiwan and Turkmenistan are provisionally included within the range of Haemaphysalis phasiana . Zhao et al. (2021) did not list Haemaphysalis phasiana as present in China , but we include that country within the range of this tick.
