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

Haemaphysalis (Rhipistoma) latitudinis n. sp. (Acari: Ixodidae) and H. (R.) setosa n. sp. are described based on adults. Adults of H. (R.) latitudinis n. sp. were mostly collected from carnivores (Carnivora: Canidae, Felidae, Herpestidae, Mustelidae, Viverridae), few specimens were found on rodents (Rodentia: Muridae), bat (Chiroptera: Molossidae) and domestic cattle (Artiodactyla: Bovidae) in Benin, Central African Republic, Côte d'Ivoire, Democratic Republic of the Congo, Ethiopia, Ghana, Kenya, Nigeria, South Sudan and Uganda. Adults of H. (R.) setosa n. sp. were mostly found on carnivores (Carnivora: Felidae, Herpestidae, Viverridae), few specimens were found on rodents (Rodentia: Muridae), hare (Lagomorpha: Leporidae), hyrax (Hyracoidea: Procaviidae) and human (Primates: Hominidae) in Kenya. Males and females of both species can be differentiated from each other and other H. spinulosa-like ticks by their size, pattern of punctations on conscutum/scutum, size of setae, shape of genital structures, size and shape of spiracular plates, dorsal cornua, posterodorsal and posteroventral spurs on palpal segment II and spur on coxae and dentition on hypostome.

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.

Two new species of Haemaphysalis Koch, 1844 (Acari: Ixodidae) in the H. (Rhipistoma) spinulosa subgroup, parasites of carnivores and hedgehogs in Africa.

Haemaphysalis (Rhipistoma) princeps n. sp. (Acari: Ixodidae) and H. (R.) camicasi n. sp. are described based on adults. Adults of H. princeps n. sp. were mostly collected from various carnivores (Carnivora: Canidae, Felidae, Herpestidae, Mustelidae, Viverridae) and hedgehogs (Erinaceomorpha: Erinaceidae); few specimens were found on hare (Lagomorpha: Leporidae), various rodents (Rodentia: Muridae) and an antelope (Artiodactyla: Bovidae) in Benin, Burkina Faso, Cameroon, Chad, Côte d'Ivoire, Ghana, Mali, Nigeria, Senegal, South Sudan and Sudan. Few adults of H. princeps n. sp. were reared from nymphs collected on rodents (Rodentia: Muridae) and shrew (Soricomorpha: Soricidae). Adults of H. camicasi n. sp. were also mostly collected from various carnivores (Carnivora: Canidae, Felidae, Herpestidae, Mustelidae, Viverridae) and hedgehogs (Erinaceomorpha: Erinaceidae); few specimens were found on different rodents (Rodentia: Muridae, Nesomyidae, Sciuridae), hare (Lagomorpha: Leporidae) and bushbaby (Primates: Galagidae) in Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Côte d'Ivoire, Nigeria, Senegal, South Sudan and Togo. Males and females of both species can be differentiated from each other and other H. spinulosa-like ticks by their size, pattern of punctations on conscutum/scutum, size of setae, shape of genital structures, size and shape of spiracular plates, dorsal cornua, posterodorsal and posteroventral spurs on palpal segments II and spur on coxae.

Identity of Haemaphysalis (Rhipistoma) muhsamae Santos Dias, 1954 (Acari: Ixodidae) and H. (R.) subterra Hoogstraal, El Kammah & Camicas, 1992, parasites of carnivores and rodents in eastern and southern Africa.

Haemaphysalis (Rhipistoma) muhsamae Santos Dias, 1954 (Acari: Ixodidae) and H. (R.) subterra Hoogstraal, El Kammah & Camicas, 1992, are redescribed based on males and females. Adults of H. muhsamae were mostly collected from various mongooses (Carnivora: Herpestidae) but also from the striped polecat, Ictonyx striatus (Perry) (Carnivora: Mustelidae), serval, Leptailurus serval (Schreber) (Carnivora: Felidae), red veld rat, Aethomys chrysophilus (de Winton) and Selinda veld rat, Aethomys silindensis Roberts (Rodentia: Muridae) in Botswana, Kenya, Mozambique, South Africa, Tanzania and Zimbabwe. Adults of H. subterra were mostly found on various species of African mole rats, Tachyoryctes spp. (Rodentia: Spalacidae) but also on striped polecat, I. striatus and slender mongoose, Galerella sanguinea (Rüppell) (Carnivora: Herpestidae) in Ethiopia and Kenya. Males and females of both species can be differentiated from each other and other H. spinulosa-like ticks by their size, pattern of punctations on conscutum/scutum, shape of genital structures, shape and size of posterodorsal and posteroventral spurs on palpal segment II, hypostome dentition, and shape and size of spurs on coxae. Taxonomic issues of both species and those related to the identity of H. (R.) spinulosa Neumann, 1906 are discussed and a neotype of H. muhsamae has been designated.
