Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 7; Rayons mous dorsaux (Total) : 10; Rayons mous anaux: 9. This species is distinguished by the following characters: predorsal fully scaled with scales entirely cycloid even above operculum; anterior nostril at end of short tube just above the upper lip; narrow suborbital, subequal to or less than pupil diameter; prepelvic area covered with large cycloid scales to below middle of operculum to posterior margin of eye. When alive, a distinct black vertical bar below eye; midsides of body with large rectangular dark spots (Ref. 118652).
Cross section: oval.
Found on gentle slope of mixed sand and small coral rubble substrate and exposed to frequent currents and coldwater upwelling. It has not been seen at depths less tha 60 m. Collected with the use of clove oil and hand nets (Ref. 118652).
