Description
The genus was described by Landau et al. in 1980.[1]
The gametocytes are sexually dimorphic with the macrogametocytes being of the 'falciparum' type and the microgametocyte of the 'malariae' type.
The schizonts develop in the lumen of the liver blood vessels inside a greatly hypertrophied host cell. They remain moderate in size and their cytoplasm is not intensely basophilic as is usually in the young stages of other mammalian Haemosporidia.
Life cycle
Host range
The only known host of these parasites is the cyclops roundleaf bat (Hipposideros cyclops).
Geographical location
These parasites are found in Gabon, Africa.
