Dermacentor steini ( Schulze, 1933b ) . Australasian: 1) Indonesia (east to Wallace’s Line); Oriental: 1) Indonesia (west to Wallace’s Line), 2) Laos , 3) Malaysia , 4) Philippines , 5) Thailand , 6) Vietnam ( Wassef & Hoogstraal 1988 , Kolonin 1995b , Durden et al. 2008 , Vongphayloth et al. 2018b , Petney et al. 2019 , Erieenor et al. 2021). Sun & Xu (2013) allegedly found Dermacentor steini in the portion of China belonging to the Oriental Zoogeographic Region, as well as in Vietnam , but Apanaskevich & Apanaskevich (2016) stated that the specimens analyzed by Sun & Xu (2013) are in fact Dermacentor tamokensis , and subsequent records of Dermacentor steini from southern China by Yuan et al. (2021) require confirmation. Neither Dermacentor steini nor Dermacentor tamokensis are listed as Chinese ticks in Zhang, G. et al. (2019) and Zhang, Y.K. et al. (2019), who ignored the papers by Sun & Xu (2013) and Apanaskevich & Apanaskevich (2016) , but Dermacentor steini is listed as found in China in Zhao et al. (2021) . In this analysis, China , but not Vietnam , is excluded from the range of Dermacentor steini .
