Diagnosis
ReferenceDiagnosis
H. W. Rasmussen 1966Marginal plate of large size comparatively to other species of the genus. Lateral faces are now parallel now slightly oblique, converging toward the internal side. Lateral faces more or less concave according to their position on the marginal frame. Lateral faces depressed in their mid-part, with a sickened fold along the external face. External face covered by thin, dense granule pits. External face of marginal plate of the disc domed.
