Seven species of orthonectids have been studied with the aid of techniques of silver impregnation, which demonstrate the arrangement of epidermal cells and the pattern of ciliation. The four recognized genera, whose type species are Rhopalura ophiocomae, Intoshia linei, Ciliocincta sabellariae, and Stoecharhrum giardi, are distinguished on the basis of these features and the disposition of sperm and oocytes. Rhopalura granosa, Intoshia leptoplanae, and Ciliocincta julini are also assigned definitively to genus. A few other species, among the 18 that have been named since 1988, are classified tentatively. Hosts for orthonectids that have not been described or identified are listed.
