Alveocystis is a genus in the phylum Apicomplexa. Species in this genus infect worms of the family Priapuloidea and molluscs. This genus has been poorly studied and little is known about it.
History
This genus was created by Bel'tenev in 1980.<ref name=Bel'tenov1980>Bel'tenov, AE (1980) Alveocystis intestinalis n. sp., n. gen. - a new species of coccidian from the intestine of Priapulida. Voprosy Parasitl Voddnyk Bespozvon. Zhivotnykh (Temat. Sbornik), Vilnyus, USSR 1980:10-11</ref>
The recognised first species of this genus was Alveocystis macrocoronata by Lüling in 1942.[1]
Taxonomy
Four species are recognised in this genus. Morphologically they resemble members of the genus Pfeifferinella.
Description
The oocysts have no sporocysts. A distinct convex micropyle is usually present at one end of the oocyst. Within each oocyst there are 8 or more free sporozoites and a large oocyst residuum.
