A new genus of righteye flounder, Samaretta gen. nov., is described from two specimens (one female and one juvenile) collected in deep waters (470–512 m) from submarine mountains of the southern eastern Pacific. The type species of the new genus, Samaretta perexilis, is characterized by unremarkable (i.e., not elongated) anterior dorsal fin rays, four pectoral fin rays, six parapophyses, reduced lateral line canals, a very slender body, large head and eyes, and minute scales. An updated key to the samarid genera is presented.
