Gidday from Australia, I have a question regarding the genus Anadara. As an archaeo-malocologist working in the tropical Pacific I deal with Anadara by the tonne - though there seems to be some confusion regarding Anadara antiquata versus Anadara scapha. Cernohorsky (1972) states that 'scapha' is a subspecies of 'antiquata', however other authors (e.g. Abbot and Dance 1982) separate them into two species. What is the current thinking on this? If they are two separate species, how does one distinguish one from the other? Thanks Kath.
