Diagnosis
ReferenceDiagnosis
J. E. Bauer and A. L. Stigall 2016Length commonly less than half the width; lateral margins gently sloping; ventral interior unknown; denticles numerous, 9 or 10 on one cardinal extremity, originating in center of hinge, terminating 1mm from cardinal extremity tip; bulbous median ridge prior to bifurcation; very faint bema.

Outline semicircular. Hinge line straight; cardinal extremities acute. Ventral interarea apsacline. Delthryium small, covered apically by rounded pseudodeltidium. Ventral interior unknown. Dorsal interarea hypercline. Denticles numerous, 9 or 10 on one cardinal extremity, originating in center of hinge, terminating 1mm from cardinal extremity tip. Cardinal process stout; chilidial plates steep; brachial process short, pointed; sockets wide, deep. Muscle scar field short, narrow; median ridges extending from central portion of brachial process, one-half shell length; lateral ridges elevated, terminating early. Bema faint, extending directly from tip of brachial process; median ridges extending anterior to extent of bema.
