Rhipicephalus sulcatus Neumann, 1908c . An Afrotropical species whose adults have been found on Mammalia (several orders). Rhipicephalus sulcatus is a rare parasite of humans.

(1987b) , Walker et al. (2000) Note: the descriptions of Rhipicephalus sulcatus in Walker et al. (2000) do not agree with those in Morel and Vassiliades (1963) because the former authors include characters of both Rhipicephalus sulcatus and Rhipicephalus turanicus , but Walker et al. (2000) are themselves confused concerning Rhipicephalus turanicus (see Rhipicephalus turanicus ). Horak et al. (2018) also warn that Rhipicephalus sulcatus can easily be confused with alleged South African Rhipicephalus turanicus . Therefore, the descriptions and redescriptions above should be considered provisional until further studies, including molecular genetic analyses, clarify the status of Rhipicephalus sulcatus .
