Diagnosis |
Snout profile low, sloping very gently. Preorbital bone narrow, its width less than half of eye diameter. Preopercular notch and knob poorly developed. Scale rows on back rising obliquely above lateral line. Generally dark brown of the upper part of the head and body with a broad white horizontal band immediately below. The lower part of the head and body dusky brown with a suffusion of yellow. A pair of white spots is on the back just below the dorsal fin base (Ref. 469).

Juveniles dorsal and ventral white, midlateral broad horizontal stripe dark brown, spots 2 white faint. Body extremely slender (for the genus), depth max 3.5-3.8.
