Dorsal fin with IX spines on the anterior (spinous) portion and I spine and 29–32 soft rays on the posterior
portion. Anal fin with II spines and 8 or 9 soft rays. Pectoral fin with 16–17 soft rays. Outer gill rakers of 1st arch 7–
9 + 15–17 = 22–25. Inner gill rakers of 1st arch 5–6 + 12–14 = 17–19. Preopercular margin weakly indented no
sharp spines. Lateral line pore scales 49–54. Circumpeduncular scales 18–20. Vertebrae 11 + 13 = 24.
Gas bladder with 26 pairs of lateral appendages, including a couple of long branched appendages extended to
the base of anal fin (Fig. 2). A pair of equally short ventral limbs at the lateral ends of gas bladder appendage,

rounded, a shallowly grooved, cauda, and a conspicuous marginal groove dorsally; outer surface more elevated at
posterior half.
Body fusiform, elongated with a moderately large head, about 3 times in standard length (SL). Head cavernous
but moderately firm. Snout 4.1–4.6 in head length, its tip with three upper and five marginal pores; rostral fold
slightly indented below the marginal pores. Eye moderately large, oval shaped, horizontal diameter 4.4–5.9 in head
length. Interorbital region broad, 3.3–4.0 in head length. Preopercular margin weakly indented without sharp spines
or serration.
