Description of four new species of Haemaphysalis Koch, 1844 (Acari: Ixodidae) from the H. (Rhipistoma) spinulosa subgroup, parasites of carnivores and rodents in Africa

Haemaphysalis (Rhipistoma) bochkovi n. sp., H. (R.) burkinae n. sp., H. (R.) horaki n. sp. and H. (R.) walkerae n. sp. (Acari: Ixodidae), are described based on males and females. Adults of H. bochkovi n. sp. were collected from the marsh mongoose, Atilax paludinosus (Cuvier) (Carnivora: Herpestidae) and the spotted-necked otter, Hydrictis maculicollis (Lichtenstein) (Carnivora: Mustelidae) in Côte d’Ivoire and Liberia; adults of H. burkinae n. sp. were collected from the rusty-spotted genet, Genetta maculata (Gray), the Haussa genet, Genetta thierryi Matschie (Carnivora: Viverridae) and the Cape hare, Lepus capensis Linnaeus (Lagomorpha: Leporidae) in Burkina Faso; adults of H. horaki n. sp. were collected from the Cape dune mole-rat, Bathyergus suillus (Schreber) (Rodentia: Bathyergidae) in South Africa; adults of H. walkerae n. sp. were collected from the striped polecat, Ictonyx striatus (Perry) (Carnivora: Mustelidae), the bat-eared fox, Otocyon megalotis (Desmarest) (Carnivora: Canidae), the aardwolf, Proteles cristata (Sparrman) (Carnivora: Hyaenidae) and the East African spring hare, Pedetes surdaster (Thomas) (Rodentia: Pedetidae) in Kenya. Males and females of these new species can be differentiated from each other and other H. spinulosa-like ticks by their size, pattern of punctations on conscutum/scutum, length of setae, shape and size of genital structures, spiracular plates, basis capituli, dorsal cornua, posterosdorsal and posteroventral spurs of palpal segment II and spur on coxae.
