A new species of Microcancilla from the southwestern Atlantic and notes on Microcancilla brasiliensis comb. nov. (Gastropoda, Cancellariidae)

Abstract

Microcancilla phoenix sp. nov., collected from the Southeast and South coast of Brazil represents the southernmost record of the genus in the Atlantic Ocean. The new species differs from the other congeners of the Atlantic mainly by the presence of microscopic pustules covering the whole shell and by dimensions of the protoconch. “Axelella brasiliensis” Verhecken, 1991, known from the Northeast to South coast of Brazil, is transferred to Microcancilla based on a similar sculpture of microscopic pustules on the protoconch and on other features of the teleoconch discussed in the present study.
