Cypria sp.

Fig. 10a-j

Description. The carapace has the typical triangular to subovate shape and shows the greatest height slightly behind mid-length. The dorsal margin is convex and passes smoothly onto both the anterior-and the posterior end. The dorso-posterior segment is being somewhat more inclined, especially on the RV. The ventral margin of the LV is almost straight, whereas the RV shows a weak concavity. The valves surface is smooth. The inner lamella is moderately pronounced, with the anterior vestibulum being slightly wider than the posterior one. The hinge is adont and the central muscle scar forms a group of four larger scars and another set of two smaller scars that are located slightly below. From the internal view the LV possess a small elongated knob at the antero-ventral end of the marginal area that corresponds to an elongate depression on the RV. Dimension: L = 0,51 – 0,58 mm, H = 0,33 –0,39 mm, the minimum sizes include juveniles too.

Remarks. The genus is a minor faunal element in the observed samples. Similar species have been described under the name Cypria tesle and Cypria pannonica by Krstić (1985) from Pannonian sediments of Serbia. The poor quality of the images of those two species from Krstić (1985) however did not allow a precise determination of the present species to either one of them.

Ecology. The genus Cypria comprise, according to Meisch (2000), approximately 35 recent species with an almost worldwide distribution, inhabiting environments with oligohaline to freshwater conditions.
