Portrait of Metopus es, the types species of this sapropelic metopid genus of ciliates. The body is elongate with a bluntly rounded anterior twisted to the left. The posterior is narrow and truncate. The peristome slants obliquely across the ventral surface. There is a prominent adoral zone of membranelles on its left and several kineties of longer cilia along its right margin. The cytostome is at the right posterior end of the peristome. The somatic kineties are longitudinal and uniform. An orange-brown aggregate of refractile granules, typical of metopids, is present in the anterior region. The contractile vacuole is terminal posteriorly. There is an anterior ellipsoid macronucleus.
