Issue
Four nominal species of Psammobatis (asper, caudispina, chilcae, maculatus), all from Hildebrand, 1946, are considered valid in Eschmeyer (CofF ver. May 2011: Ref. 86870) following Chirichigno & Vélez (1998), but J. McEachran confirmed their synonym status of Sympterygia brevicaudata (Cope, 1877) (pers. comm., 11/2003).
