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

[edit]

This genus was created by Bel'tenev in 1980.[1]

The recognised first species of this genus was Alveocystis macrocoronata by Lüling in 1942.[2]

Taxonomy

[edit]

Four species are recognised in this genus. Morphologically they resemble members of the genus Pfeifferinella.

Description

[edit]

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.
