DESCRIPTION OF ALECTOROBIUS (RETICULINASUS) CAMICASI SP. NOV. (ACARI,IXODOIDEA, ARGASIDAE), A PARASITE OF FRUIT BATS ROUSETTUS-AEGYPTIACUS-OCCIDENTALIS IN SENEGAL

A new tick species - Alectorobius (Reticulinasus) camicasi n. sp., a p arasite 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. s p. 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 (Reticulin asus) faini (Hoogstraal, 1960), a parasite of Rousettus leachii (Smith ) in the Congo. The new Senegalese species is easily distinguished fro m the Egyptian species by shape of dorsal surface of idiosoma of adult s, coral setae and hypostomal formula of the larva. It is very similar to the Congolese species, but differs from it by the appearance of th e antero-dorsal surface-of idiosoma of male, and by the hypostomal for mula, dorsal plate, length of fourth palpal article, and the position and distance between some setae of the larva.
