Orcheobius is a genus of parasitic alveolates of the phylum Apicomplexa.[1]
The genus was created by Schuberg and Kunze in 1906.
The genus Cariniella was synonymised with Orcheobius by Levine in 1980.[2]
There are two species known in this genus.
The oocysts have 25 or more sporocysts.
Each sporocyst produces 4 sporozoites.
The gamonts are elongated.
During syngny, four microgametes associate with the macrogamete. One microgamete penetrates the macrogamete and the remaining three die off.
