. Lorica hemispheroidal, suboval in dorsal view, moderately wider than long. Lorica more or less symmetrical in dorsal view; width of right half from midline to edge not noticeably greater than width of left half from midline to edge. Rim of lorica not thickened. Dorsal surface of lorica without curved ridge. Posterior part of vallum reduced to slightly thickened ridge. Anterior and lateral parts of vallum moderately tall; posterior edges of lateral parts sloping abruptly to posterior part of vallum and flaring outward. Free edge of vallum smooth, even, usually with spine on left margin. Spine varying from absent to as long as width of body of vallum. Long strip near base of inner wall of each anterolateral part of vallum moderately thickened and projecting inward to form prominent, protruding fold. Rim of lorica aperture heavily thickened. Operculum subcuneate in dorsal view. Anterior edge of operculum moderately thickened to form narrow, ventral shelf; ventral shelf smooth, lacking processes. Macronucleus elongate, cylindroid, usually folded to make compact mass. Macronucleus located in left half of body. Micronucleus ovoid, almost always located near centre of macronucleus rather than near either end.
