Body extremely slender. Dorsal and ventral coloration sharply contrasted; fine dark horizontal lines forming series of fine dots and dashes on upper half of body; a dark ventral saddle near middle of caudal peduncle. Head relatively short (usually < 21% TL). Caudal peduncle very elongate (usually > 23% TL). Eyes rather narrow; upper eyelid with pale naked patch. Denticles extremely dense, bristle-like, not arranged in defined rows. Flank-marking base forward of second dorsal-fin spine; its posterior branch longer than anterior branch and extending beyond free rear tip of second dorsal fin; central caudal marking absent. Monospondylous centra 41-45 (Ref. 45056).
