Tectonatica mevsi, a new Miocene naticid gastropod from northwest Germany

A new naticid of Miocene (Langhian) age, Tectonatica mevsi, is described on the basis of material collected from two boreholes more than 500 km apart, one in Schleswig-Holstein, the other in the Lower Rhine area (NW Germany). Interestingly, the samples which have yielded T. mevsi are both dated at c. 16 Ma ( Uvigerina acuminata Zone). The new species may be closely related to the Late Oligocene T. globulariaeformis R. Janssen, 1978.
