Abstract

ActeonsemicingulatusDall, 1927, previously known only by its original description is reassigned to the Pyramidellidae, inOndina, based on the collecting of several new specimens along the coast of Brazil, in the same bathymetry as the type locality. Its shell shape variation is discussed and Odostomia (Evalea) ryclea Dall, 1927 is considered a synonymy. Other Western Atlantic species, previously allocated to other genera are transferred toOndina:AclisstriataVerrill, 1880, Odostomia (Iolaea) hendersoni Bartsch, 1909,EvaleastockiDe Jong & Coomans, 1988 and Odostomia (Evalea) emeryi Bartsch, 1955 based on conchlogical comparison to the revison by Høisæter (2014), from Northeastern Atlantic. The genusEvaleais considered to be absent in the Atlantic Ocean.
