Diagnosis

Body with about equal stripes of brownish red and silvery white; spinous dorsal mostly white, membrane tips yellow, basal part of fin red except base of first two membranes which are whitish (Ref. 4201). Five oblique scale rows on cheek; body depth 2.4-2.65 in SL; head length (HL) 2.55-2.9 in SL; short and blunt snout, its length 4.15-4.6 in HL; interorbital width 4.5-5.2 in HL; mouth terminal, maxilla usually extending posterior to center of eye, upper jaw length 2.2-2.45 in HL; premaxillary groove nearly or just reaching a vertical at front edge of orbit; anterior end of nasal bone with a blunt spine; surface or medial edge of nasal bone spineless; nasal fossa without spinules; upper edge of 1st suborbital bones with a row of recumbent spinules, the 1st (slightly posterior to a vertical at front edge of orbit) is the largest and most lateral; preopercular spine usually slightly more than 1/2 orbit diameter, 4.0-5.7 in HL; 3rd-5th dorsal spines longest, 1.75-2.15 in HL; 3rd anal spine 1.3-1.55 in HL (Ref. 27370).
