[Dionisia bunoi n. g. n. sp., Haemoproteidae parasite of the microchiropteran bat Hipposideros cyclops in Gabon (author's transl)].

Dionisia bunoi ng. g., n. sp. is characterized by:--a) sexual dimorphism of gametocytes, macrogametocyte of the falciparum type, microgametocyte of the type malariae:--b) schizonts developing in the lumen of liver blood vessels inside a greatly hypertrophied host cell; their size remains moderate and their cytoplasm is not intensely basophilic as is usually in the young stages of Haemosporidia of Mammals. The genus has morphological characters in common with each of the 4 other genera of Haemoproteidae of Mammals. The phyletic hypothesis concerning the morphology of gametocytes and schizonts suggests that Bioccala and Dionisia are primitive.
