Homonymy

This is a replacement name for ''Odostomia pretiosa'' Turtom, 1932 on grounds of secondary homonymy with ''Pyrgulina pretiosa'' Dautzenberg & Fischer, 1906, however such homonymy did not exist at the time of replacement as Saurin (1962) had transferred the senior name to ''Miralda'' (see ICZN Article 59.2). Aartsen & Corgan's name will be needed if the taxa are regarded as congeneric in the future.
