Homonymy Replaced by Pyrgulina sowerbyi van Aartsen & Corgan, 1996 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).
