Hello all,

One for all the marine malacologists out there.

In /Taxonomic Problems of the Genus Olivia/ by Bernard Tursch the author 
asks a rhetorical question regarding delimination of species in marine 
molluscs "has any species of marine mollusc ever been defined by direct 
proof of reproductive barriers?" In the context of the paper the author  
is emphasisng the use of morphospecies as an indirect approach to the 
biological species concept. It got me wondering in the 7 years since the 
publication of this paper has there been any species of marine mollusc 
deliminated solely by evidence of reproductive barriers? Any further 
reading would be greatly appreciated.

Thank you,

Adam Jenkins
