Genus Turbonilla Risso, 1826
The Genus Turbonilla as commonly used is doubtless a polyphyletic assemblage. Schander et al. (1999) listed more than 40 genera in Turbonillinae . The knowledge of most of these genera are however scarce, and we therefore feel that we currently can not divide the West African species in a proper phylogenetic way, but are forced to place the new species in Turbonilla sensu latu. A proper revision of the family Turbonillidae is urgently needed.
