背棘 (總數) : 11; 背的軟條 (總數) : 14 - 16; 臀棘: 3; 臀鰭軟條: 9 - 10. Diagnosis: Distinguished from its congeners with the following characters: dorsal-fin rays XI, 14-16 (usually 15); scales above lateral line 10-15 (usually 12-14), below 20-27 (usually 22-25); maxilla scaly; 10 pores on and behind chin, including 1 very small pore near symphysis on each side (may be difficult to detect, obscured by short dense papillae), 2 moderate-sized pores anteroventrally on each dentary, a single large pore ventrally, at articulation of dentary (2 posteriormost usually slit-like and concave), its posterior part scaly; shape of dorsal- and anal-fin rays rounded and slightly angulated, respectively; cluster of very short dense papillae on fleshy lower lip; body often with two indistinct oblique dark bands, the first descending from nape to behind pectoral fin and then running to posterior part of soft anal-fin rays, and the second from base of anterior 3rd or 4th dorsal-fin spine and soft dorsal-fin base, curving backwards through lateral line to upper part of caudal peduncle (Ref. 56360).
幼魚與受驚的個體的身體有兩個不明顯的斜紋; 在較大的成魚中，這些條紋通常是不明顯的。 平伏的刺狀突起通常不是明顯, 藏在了背部的鱗片。 沒有鱗片在顎骨上。 十個下巴孔在下頜上，加上在瘉合處附近的 2個非常小的孔 (藏在觸鬚的群) ，加 4個孔。 (有時狹長狀的, 部份地具有一個凹洞或整個隱蔽著在後部地經由一個膜) 發展良好的乳突而且觸鬚在肉質的下唇上。 沒有在背鰭、尾鰭與臀鰭上的深色邊.(參考文獻 36944)
