The monotypic genus Defretinella Hennere, 1966 is characterizated by oocysts containing >50 bivalved sporocysts, each sporocyst with numerous sporozoites. Because of the bivalved nature of the sporocysts, Levine (1983) placed this genus in close proximity to Barroussia and Goussia (Eimeria). Additional studies are warranted to determine whether this coccidian should remain aligned with the other Eimeriidae.
