Snout long, smoothly conical in lateral profile, narrow in dorsal view, its length 41–56% HL, about 2.0 times orbit; anterolateral margin of snout incompletely supported by bone; orbit 20–21% HL, its dorsal margin well below dorsal profile; upper jaw 30–37% HL; nasal fossa scaled anteriorly and ventrally; underside of head fully scaled. Light organ group II of Iwamoto (1990), fossa narrow and short, not extending to pelvic-fin bases. Spinules on body scales sharp, blade-like, in 5–7 slightly divergent, crestlike rows, middle row strongest. Ground color light brown, bluish over abdomen; about 5 prominent saddle marking interspersed with pale narrow bars from trunk to tip of tail; mouth and gill cavity blackish; fins dusky, but pelvic fins blackish except for white outer prolonged ray; margin of A blackish.
