[Description of P. cyclopsi n. sp. a parasite of the microchiropteran bat Hipposideros cyclops in Gabon (author's transl)].

P. cyclopsi sp. nov. is characterized by the small size of the asexual stages and by gametocytes belonging to the type "malariae". It is related to P. anomaluri and the hosts of both species share the same habitat: hollow trees of the tropical forest. By the ancientness of its vertebrate host and its relationship with the "malariae" group of Haemosporidia P. cyclopsi is interpreted as a primitive species.
