摘要

A new species of deepwater cardinalfish, Epigonus zonatus [2 specimens, 79.0–80.3 mm in standard length (SL)] is described based on specimens from Jardines de la Reina, Cuba. Epigonus zonatus is distinguished from other congeners by a combination of the following characters: dorsal-fin rays VII-I, 10; pectoral-fin rays 17; total gill rakers 26–27; vertebrae 10 + 15; pyloric caeca 8; pored lateral-line scales 48 + 5; opercular spine absent; maxillary mustache-like processes absent; ribs on last abdominal vertebra present; tongue toothless; endopterygoid teeth absent; enlarged conical teeth on symphysis of lower jaw present; and dark band on first dorsal fin present. New records of Epigonus fragilis were collected off New Caledonia (2 specimens: 127.0–160.1 mm SL), Papua New Guinea (68.4 mm SL), and Taiwan (147.7 mm SL), which represents the first records of this species from the western South Pacific and South China Sea. Epigonus zonatus and E. fragilis belong to the Epigonus pandionis group, and the morphological characters of similar species are revised.
