| abstract | A new tick species - Alectorobius (Reticulinasus) camicasi n. sp., a parasite of fruit bats, Rousettus aegyptiacus occidentalis, in Senegal - is described. This new species is based on laboratory reared males, females, nymphs and larvae. Alectorobius (Reticulinasus) camicasi n. sp. is closely related to the two other African species: Alectorobius (Reticulinasus) salahi (Hoogstraal, 1953), a parasite of the fruit bat Rousettus aegyptiacus (Geoffroy) in Egypt; and Alectorobius (Reticulinasus) faini (Hoogstraal, 1960), a parasite of Rousettus leachii (Smith) in the Congo. The new Senegalese species is easily distinguished from the Egyptian species by shape of dorsal surface of idiosoma of adults, coral setae and hypostomal formula of the larva. It is very similar to the Congolese species, but differs from it by the appearance of the antero-dorsal surface-of idiosoma of male, and by the hypostomal formula, dorsal plate, length of fourth palpal article, and the position and distance between some setae of the larva. |
