Urotrygon nana occurs from the west coast of Mexico and Costa Rica and is distinguished by its small eyes, dense covering of denticles on snout and margin of the disc and small size at maturity. U. reliculata occurs off the Pacific coast of Panama and is distinguished by its fine tan to brownish vermiculations. U. simulatrix occurs off the Pacific coast of Panama and is distinguished by its stout cone-shaped and slightly recurved denticles covering the dorsal surface and broad yellowish-white border along the dorsal disc and pelvic fins.
