Description of Dionisia
provided by BioPedia
Plasmodiid apicomplexa, macrogametes of the falciparum type; microgamonts of the malariae type; meronts small, in blood vessels of liver, developing in a very modified host cell; nuclei of meronts simple, formed by a single chromatin mass; in bats. Monotypic. Type species: Dionisia bunoi Landau, Chaubaud, Miltgen & Baccam,1980.
Description of Mesnilium
provided by BioPedia
Plasmodiid apicomplexa, merogony in erythrocytes and reticulo-endothelial cells; gamogony in erythrocytes; pigment granules present only in microgamonts and macrogametes; in fish; probable vectors leeches. Monotypic: Mesnilium malariae.
Description of Plasmodiidae
provided by BioPedia
Haemosporid sporozoan apicomplexa, includes agents of malaria and similar diseases in man, lower primates, other mammals, birds, and reptiles; more than 400 named species; all are heteroxenous; genera (and subgenera) are differentiated on the morphology of the erythrocytic stages, endogenous development in the tissues and the type of vector; species identification may require study of the tissue stages; bird species catalogued by the International Ref Centre for Avian Haematozoa.
Description of Rayella
provided by BioPedia
Plasmodiid apicomplexa, similar to Hepatocystis, but with merocysts in clusters in liver, 2 species, from flying squirrels. Type species: R. rayi.
Plasmodiidae

The Plasmodiidae are a family of apicomplexan parasites, including the type genus Plasmodium, which is responsible for malaria. This family was erected in 1903 by Mesnil and is one of the four families in the order Haemospororida.
Diagnostic criteria
The diagnostic criteria of the Plasmodiidae are:
Taxonomy
The family Plasmodiidae has three sister taxa in the order Haemospororida: the families Garniidae, Haemoproteidae, and Leucocytozoidae.
The Haemoproteidae and the Plasmodiidae both produce pigment, and these have been placed in the suborder Laveraniina.
Neither the Haemoproteidae nor the Leucocytozoidae have an asexual cycle in the peripheral blood.
The Garniidae do not produce pigment, but do have an asexual cycle in the blood. They appear to be the earliest diverging clade in this group.
The Plasmodiidae contain these genera:
The genus Mesnilium is the only taxon that infects fish. The genus has a single species and has been reported only once. This genus may have been mistakenly placed in this genus. DNA studies are likely to be needed to clarify this point.
