Eugregarinorida

Spore of Lithocystis minchinii, from Goodrich (1929).

Belongs within: Sporozoa.

The Eugregarinorida are a major subgroup of the gregarine parasites, found in a wide range of invertebrate hosts.

Characters (from Adl et al. 2019): Trophozoite with epimerite in gregarines with septum or mucron in gregarines without septum; syzygy followed by encystment of gamonts; oocysts with eight sporozoites.
