Taxonomy of Ciliophora. 1. Shellositon gen. n. from littoral amphipods in the Sea of Japan (Peritricha: Rovinjellidae)
A.W. Jankowski
Abstract. A growing number of colonial genera with shell are described in the literature within both epistylid and operculariid groups of Sessilida. An annotated list is presented, and a new genus Shellositon is added to shelled forms outside the classical taxon Loricata. Unlike all known genera of shelled non-loricate sessilids, Shellositon includes only solitary zooids with a large folded shell and small myoneme merged into the thickened shell basis. Its single species S. branchialis lives on Pacific amphipods.
