Diagnosis
ReferenceDiagnosis
L. Villier 2010Marginal ossicles flattened, rectangular in outlines, two-fold differentiated into a quadrate adradial part on which the adjoining ossicles abut and a more or less prominent, strongly ornamented, abradial extension. External face with ornament of two to four poorly differentiated rows of crater-shaped tubercles. Abradial extension with ridges and grooves on its intermarginal side. Intermarginal face coarsely triangular, reduced to 30% to 50% of the ossicle width. Lateral faces flattened, reduced, and irregular in size and shape. The radial ossicles are wider than long, with ridges and grooves throughout the external face. Ossicle of the disc large, robust, block like with a similar ornament as other dorsal ossicles.
