Rhipicephalus rossicus Yakimov & Kol-Yakimova, 1911 .

Zahler et al. (1997) found molecular evidence suggesting that Rhipicephalus pumilio and Rhipicephalus rossicus are conspecific. Okely et al. (2022) treated Rhipicephalus rossicus as a non-endemic species in Egypt , but this country is provisionally included within its range here. Mihalca et al. (2015) included Poland and Tajikistan within the range of Rhipicephalus rossicus , but NowakChmura & Siuda (2012) treated this tick as an invasive species that has been unable to establish itself in Poland , which is provisionally excluded from the range of Rhipicephalus rossicus , while the presence of this species in Tajikistan is treated here as unconfirmed. Zhang et al. (2021 , supporting information) listed Rhipicephalus rossicus as occurring in Hainan , southern China (Oriental Zoogeographic Region), but its presence there also requires confirmation.
