One group including the species C. fasciata (Lagerstedt) Cleve (pictured by Antoniades et al. 2009, figs 4 – 6), C. fusus Hamilton & Antoniades in Antoniades et al. (2009, figs 50 – 58), C. schumanniana (Grunow) Cleve and C. lewisii Patrick (pictured by Stancheva et al. 2009, figs 39 – 42 and 43, 44 respectively) is characterized by a shallow valve mantle almost regular in depth around the valve. The second group includes C. australis Zidarova, Kopalová & Van de Vijver (2016: 40, figs 13 – 17), C. mendosina (this study), C. silicula f. peisonis (pictured by Cocquyt 1999, figs 26 – 29) and is characterized by having a deep valve mantle, slightly or abruptly shallower at the apices. Among the mentioned species C. mendosina is the only one that shows a mantle with curved proximal region and vertical distal region.	en	Sunesen, Ines, Tardivo Kubis, Jonas A., Sar, Eugenia A.
