Description. The carapace commonly shows a wide variety of forms but in general is of elongated shape with the greatest height slightly behind mid length. The dorsal margin is slightly convex and slopes smoothly onto the broadly rounded anterior end whereas towards the posterior it is convex and steeply sloping. The lower part of the LV appears slightly pointed and continues in a round fashion onto the ventral margin distinctively concave in the median area and passes smoothly onto the narrowly rounded posterior-ventral end. The LV overlaps the RV at both ends. A number of close-set and curved anterior marginal pore canals are present in the widely pronounced marginal area. Sexual dimorphism is occurring. The male carapace appears to be slightly longer and the ventral concavity is more pronounced. Dimension: L = 1,02- 1, 18 mm; H = 0,52 - 0,60 mm.

Ecology. C. candida is found in an exceptionally wide range of aquatic habitats, ranging from littoral to profundal zones of lakes ( Meisch, 2000). It further has been observed in ponds and rivers and some juveniles prove to be resistant against desiccation, and from slightly salty (lower mesohaline) inland-and coastal waters. This species has been described in freshwater sediments from the Getian in the western region of the Dacian basin ( Olteanu, 1995), the Apsheronian and Akciagilian level from the Circum-Causcasian area and Central Asia ( Suzin, 1956; Agalarova et al., 1961; Yassini, 1986).
