A new species and range extension of Ponderinella (Gastropoda, Tornidae) in West Africa

Two species with similar shell characters collected on the Gabon coast are studied. One of them is here described while the other was already described in the genus Notosetia from the Ghana coast. The generic assignation is discussed concluding that tentatively it is better that both (close to P. minutissima) should be placed in the genus Ponderinella.
