A contribution to the anatomy and histology of the female reproductive system of Amblyomma cajennense (Acarina: Ixodidae).

: The genital system of the tick Amblyomma cajennense is composed of several parts: a single tubular ovary where a great number of ova develop except for a longitudinal groove on its dorsal surface, with feeding the ova develop multiplying the size and weight of the ovary, as they reach maturity they are ovulated into the lumen. Two oviducts are connected to the ovary on each side, these thicken at a certain region forming the knee shaped ampulla. This significant region is where great numbers of mature spermatozoa are found. The vagina is composed of a vestibular and a cervical part and leads to the exterior by the genital aperture. A large seminal receptacle opens into the cervical vagina, the function of the receptable is to receive and store endospermatophores.
