2. Rhipicephalus appendiculatus Neumann, 1901. An Afrotropical species, all of whose parasitic stages are usually found on Artiodactyla: Bovidae, but they have also been collected from Mammalia (several orders), and Galliformes: Numididae and Phasianidae. Adult ticks alone have been recovered from Passeriformes: Laniidae, and Testudines (unknown family), while immature stages have been taken from Aves (several orders). Rhipicephalus appendiculatus is a sporadic parasite of humans. M: Neumann (1901) F: Neumann (1901) N: Howard (1908) L: Howard (1908) Redescriptions M: Hoogstraal (1956a), Walker et al. (1981, 2000), Walker A. R et al. (2003), Horak et al. (2018) F: Hoogstraal (1956a), Walker et al. (1981, 2000), Walker A. R et al. (2003), Horak et al. (2018) N: Walker et al. (1981, 2000) L: Arthur (1975a), Walker et al. (1981, 2000) Note: Walker et al. (2000) state that it can be very difficult, or sometimes impossible, to morphologically separate Rhipicephalus appendiculatus and Rhipicephalus zambeziensis, but Rhipicephalus appendiculatus has also been confused with other Rhipicephalus species. Walker et al. (2000) selected a lectotype and paralectotype of Rhipicephalus appendiculatus from Tanzania to avoid confusion with Rhipicephalus zambeziensis or Rhipicephalus nitens. There are other redescriptions of Rhipicephalus appendiculatus that were not included in the above lists because of doubts concerning the identity of the specimens involved.
