Abstract

Nine new species of Haemaphysalis are here described based on a morphological analysis of 7,077 adult specimens stored in the U.S. National Tick Collection (Georgia Southern, Statesboro, USA) and collected from various carnivores (Carnivora: Canidae, Felidae, Herpestidae, Hyaenidae, Mustelidae, Nandiniidae, Viverridae) and hedgehogs (Erinaceomorpha: Erinaceidae); few specimens were found on hares (Lagomorpha: Leporidae), various rodents (Rodentia: Bathyergidae, Cricetidae, Muridae, Nesomyidae, Pedetidae, Sciuridae, Spalacidae) and other mammals (Artiodactyla, Chiroptera, Hyracoidea, Perissodactyla, Primates, and Soricomorpha) in 29 sub-Saharan African countries. In addition to descriptions of new species, 4 species, namely H. spinulosa Neumann, 1906, H. muhsamae Santos Dias, 1954, H. ethiopica Santos Dias, 1958 and H. subterra Hoogstraal, El Kammah & Camicas, 1992 are redescribed and their taxonomic issues are discussed; one previously valid species H. norvali is synonymized under H. ethiopica. Geographic distributions for all new species are provided, and those for previously described species are updated. Insight into host-parasite relationships is given for all new and previously described species. Males and females of all new and previously described 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, all of which are illustrated via scanning electron micrographs and digital photographs.
