Deskripsi
Acteon semicingulatus Dall, 1927, previously known only by its original description is reassigned to the Pyramidellidae, in Ondina, 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 to Ondina: Aclis striata Verrill, 1880, Odostomia (Iolaea) hendersoni Bartsch, 1909, Evalea stocki De Jong & Coomans, 1988 and Odostomia (Evalea) emeryi Bartsch, 1955 based on conchlogical comparison to the revison by Høisæter (2014), from Northeastern Atlantic. The genus Evalea is considered to be absent in the Atlantic Ocean.
