Diagnosis
ReferenceDiagnosis
R. von Cosel 2006Shells small, mostly under 10 mm, variable in outline, subcircular, slightly longer than high to almost as long as high, moderately tumid, with a broad anterior and posterior part and a more or less truncated, very slightly or not indented posterior margin. Anterior margin more convex in its middle part. Beaks in or just in front of the vertical midline. umbones rather prominent. Surface with more or less developed, densely spaced fine commarginal lamellae, which may be obsolete on the middle part of the disk. Antero-dorsal area small and hardly separated, a depression may be visible. Posterior angle rounded, postero-dorsal depression broad and shallow but well developed. Lunule small, not too narrow, only slightly asymmetrical. escutcheon entirely filled with the ligament. Hinge plate more or less narrow, with slight vestiges of one or two cardinals. Diverging part of anterior adductor scar short and broad, with a length of about half the total length of the scar. Inner margins smooth.
