Rhipicephalus haemaphysaloides is a sporadic parasite of humans. M: Tonelli Rondelli (1926a) , under the name Rhipicephalus pulchellus humeralis and given its current status in Zumpt (1950) F: Walker (1957) N: Walker (1957) L: Walker (1957) Redescriptions M: Zumpt (1950) , Matthysse and Colbo (1987) , Walker et al.

(2000) state that it can be difficult to morphologically separate females and nymphs of Rhipicephalus humeralis from those of Rhipicephalus pulchellus , but the larvae of these species are even more difficult to distinguish from each other.
