The dorsal margin is almost straight, passing in an obtuse angle onto the posterior-and the anterior end. The anterior angle is more obtuse and the hinge margin, in some cases, extends onto the anterior border. Both the anterior and the posterior ends are smoothly passing onto the medially slightly concave ventral margin. The sculpture consists of randomly and interlacing high plications, the transversal ones being more pronounced. The species has a clear arcuate posterior crest. Another one is running more or less parallel to the anterior margin before finally reaching the antero-dorsal cardinal angle. The hinge is well developed and amphidont, with a crenulated bar that bears enlarged toothlets anteriorly- and posteriorly. A snap-pit is present in the concavity located in the middle of the ventral margin. The inner lamella is well developed, both in the anterior-and posterior ends and continues along the ventral margin. Dimension: L = 0,53 – 0,58 mm, H = 0,30 – 0,32 mm, the minimum sizes include juveniles too.</p><p><i>Chronostratigraphical and geographical distribution.</i> Inside the Central Paratethys this species is described from the Pontian deposits of the Eastern area of the Pannonian Basin (Bulgaria and Yugoslavia), the Dacian Basin (Sokač, 1990; Olteanu, 1989; Olteanu, 2011; Stoica et al., 2013) and the Pontian of the Bădislava – Topolog area of Romania (Floroiu et al., 2011). In the Eastern Paratethys it is known from the late Pliocene (Pontian, Apsheronian) of the southern parts of Azerbaijan (Van Baak et al., 2013, 2016) Turkmenistan and the north Caucasus region (Sokač, 1990).
