Description: Body relatively thin, long, and narrow with a medium eye and a terminal medium mouth. Pectoral fins long, reaching to or past vent. Pelvic fins medium, extending about two-thirds the way to the vent, with a flat frenum not forming an obvious cup. Dorsal and anal-fin bases medium length and caudal peduncle medium length and width, procurrent caudal-fin rays usually 6 (5-6 spindly). A single melanophore on the caudal peduncle ventral midline just after the last anal fin and internal melanophores only at the dorsal surface of the swim bladder and sometimes around the gut near the vent. The eye is slightly vertically-narrowed and has a coarsely-speckled membrane overlying the upper iris. Many larvae have a pair of large spiny scales on the tail over the base of the uppermost and lowermost segmented caudal-fin rays. Transitional larvae first develop a sparse scattering of small discrete melanophores on the upper head, then a pair of melanophores behind the tip of the upper jaw, a few on the anterior upper jaw and an incipient stripe from the eye to the mid upper-jaw.
