Family Cardiidae Lamarck, 1809

Remarks. For the genus Cerastoderma , the species status of Pontocaspian material is subject of debate where morphological and increasingly molecular arguments show the possibility of sibling species occurrences ( Sromek et al. 2016). The genus Didacna is relatively well established, however much uncertainty exists over distinction between the genera Monodacna , Adacna , and Hypanis . The generic concepts have shifted through time. Only lately, Kijashko in Bogutskaya et al. (2013) treated Monodacna as a subgenus of Adacna . Büyükmeriç and Wesselingh (2018) discussed the distinction between the three genera and considered Monodacna , Adacna , and Hypanis as valid.
