Diagnosis
ReferenceDiagnosis
A. A. Berezovsky 2018Umbonal region at distance of 2.5 mm from umbonal apex lacking ribs, having only growth lines. Concentric ribs covering remaining shell part low, densely spaced, triangular in cross section. Valves about 10 mm of height containing 27–28 ribs. Distance between middles of neighboring ribs in lower part of central field of these specimens ranging from 0.4 to 0.6 mm (usually 0.50–0.55 mm). 4-mm-high area, upper boundary of which located at distance of 2 mm from umbo, containing 14–15 ribs. Lateral surfaces of cardinal dentes lacking distinct transverse notches.
