Characters
Moderately elongate, slender, and compressed, with an acute snout and a forked tail. Snout length is less than eye length and is 5.3% to 6.9% of SL. Head length is 27% to 29% of SL. Upper jaw extends to posterior margin of pupil. Symphysis of lower jaw has horizontal spine projecting laterally on each side. Premaxilla, maxilla, and dentaries have single series of minute teeth. Palatine and vomer have one or two tiny fangs. Forwardly directed teeth (tusks) are absent on premaxilla, and lateral, horizontally directed teeth are lacking in lower jaw. Gill rakers on first arch number from 17 to 20. Branchiostegal rays number 7 or 8. Pectoral fin is low on flank, short, and has 20 or 21 rays. Dorsal fin originates posterior to pelvic fin origin and has 15 to 21 rays. Pelvic fin is inserted on belly at about midlength and has 7 or 8 rays. Anal fin originates below midlength of dorsal fin base and has 14 to 17 rays. Body is covered with moderate-sized scales, with about 45 to 55 in lateral series, 7 to 10 from dorsal fin base to lateral line, and 7 to 10 from lateral line to anal fin base. Lateral line scales are similar to other scales. Photophores are absent.
Color is uniform dark except scales along belly are opalescent.
