A deepwater cardinalfish, Hynnodus megalops Smith and Radcliffe in Radcliffe, 1912, originally described from four specimens from the Philippines, is redescribed as a valid species of Epigonus. Epigonus megalops is similar to E. atherinoides (Gilbert, 1905) but differs in having a relatively longer head and upper jaw, a relatively deeper caudal peduncle, and ctenoid scales on the lateral sides of the body. Epigonus atherinoides is redescribed based on the holotype, previously known specimens, and newly collected ones from the Society Islands and Western Australia. Additionally, two specimens of E. draco Okamoto, 2015 collected from the Society Islands represent the first record of this species from the central South Pacific.
