Entodiniomorph Ciliates from the Stomach of <i>Hippopotamus amphibius</i>, with Descriptions of Two New Genera and Three New Species

Abstract

SYNOPSIS Entodiniomorph ciliates, belonging to the family Cycloposthiidae, are described from the stomach contents of Hippopotamus amphibius. Monoposthium acanthum gen. n., sp. n., with typical cycloposthiid structure, differs from other genera in having only 1 caudalium. Parentodinium gen. n., represented by P. africanum sp. n. and P. ostrea sp. n., although superficially resembling Entodinium , is considered to be a relatively unspecialized cycloposthiid.
