Diagnosis
ReferenceDiagnosis
J. Kriz 2011Tetinka with dorso-ventrally elongated, inequivalve, inequilateral, narrowly ovate, and inflated shells. Enantiomorphous, distinctly inclined to the right. Umbonal angle in the left upper valve is 31–45°. Posterior wing is relatively large, separated from the central part of the shell by shallow and relatively wide radial sulcus which ends in the central part of the posterior margin, parallel with frontal face. Posterior margin is here slightly concave. Outer surface sculpture formed by growth wrinkles and regular narrow growth bands in combination with weak radial ribs. When the uppermost layer of the shell is etched or eroded fine, numerous radial striae are visible. Inner surface radial ribs are most prominent on frontal face (24) and posteriorly of posterior wing (6–9). In the central part of the shell are numerous radial ribs (28–32) less prominent, best preserved on the ventral margin as crenulations.
