[Considerations on the genus Nycteria (Haemoproteidae) parasite of African Microchiroptera with the description of 4 new species (author's transl)].

5 species of Nycteria from Central Africa (Gabon and Congo-Brazzaville) were studied. They can be divided into two distinct groups: the parasites of Nycteris with gametocytes "en cocarde": N. medusiformis, N. houini n. sp. and N. eradi n. sp.; the parasites of Rhinolophus with gametocytes of the "diffus" type: N. gabonensis n. sp. and N. krampitzi n. sp. The characteristics of the genus Nycteria and its place amongst the other Haemosporidia are analysed.
