Characters
Elongate and polygonal in cross section, with a moderately short snout and a deeply forked caudal fin. Body depth at dorsal fin origin is 10.1% to 14%, body depth at caudal peduncle is 5.3% to 6.8%, head length is 27.2% to 30%, snout length is 8% to 10.2%, and maxillary length is 6.7% to 8.9% of SL. Maxillae meet or are separated by narrow space anteriorly. Palatine and head of vomer bear small, conical teeth. Teeth on vomer are set posteriorly relative to those of palatine and do form continuous band. No teeth occur on maxilla or dentaries. Tongue has two to six teeth along anterior margin. Lower limb of first gill arch has 21 to 23 gill rakers. Branchiostegal rays number 5. Anus is located anterior to origin of anal fin by distance of depth of caudal peduncle or more. Pectoral fin is on ventrolateral aspect of body and possesses 12 to 14 rays. Dorsal fin originates anterior to pelvic fin and has 10 to 12 rays. Pelvic fin has 10 to 12 rays. Anal fin is located below adipose fin and has 11 to 13 rays. Scales are deciduous and lack spines. Lateral line scales do not extend onto caudal fin. Vertebrae number 43.
Color is uniform light tan, often with dark stripe on dorsolateral margin of body. Stripe may be reduced to lightly pigmented band. Poorly defined lateral and ventrolateral bands are formed by large brown chromatophores. Bands meet at caudal fin base, coloring caudal peduncle brown.
