Description
Rounded, subcircular to ovate, globose, biconvex, weakly carinate or noncarinate, small orthocline area, apical foramen, minute deltidial plates, finely ribbed, imbricate ornamentation produced by less than 1-mm-spaced, short growth lamellae, rectimarginate to flat, widely plicate commissure, shell wall thin, teeth with possible dental cavities, muscle scars weakly incised, hinge plate delicate, spiralia of fewer than 6 whorls, dorsally directed, jugal processes undescribed (from silicified type material). [Ornamentation similar to possibly congeneric Atrypinella, but lacking strong bisulcation of type species; differs from Limbatrypa in imbricate ornamentation; affinities with Atrypinellinae uncertain, possibly referable to Atrypinae.]
