背棘 (总数) : 11; 背的软条 (总数) : 16 - 18. Diagnosis. Distinguished from its congerners by the following: dorsal-fin rays XI, 16-18 (usually XI, 17); scales above lateral line 9-12 (usually 10 or 11), below 15-19 (usually 16 or 17); scales on maxilla absent; 10 pores on and behind chin, including one very smalei pore near each side of symphysis, two moderate sized pores anteroventrally on each dentary, a single large pore ventrally, midway along each dentary (usually obscured by dense papillae), and a single large pore ventrally at articulation of dentary (two posteriormost pores slit-like concave traces); cluster of short and long dense papillae and barbels on fleshy lower lip, its posterior part naked; shape of dorsal- and anal-fin rays strongly angulated, usually angular, anal more strong than dorsal; body uniformly dark brown, sometimes with two indistinct oblique dark bands, the first descending from nape to behind pectoral fin, the second from base of 7th-10th dorsal-fin spines, curving downward above or through lateral line (Ref. 56360).
鉴别。 与它的 congerners 区分了藉由跟随: 背鳍鳍条 11, 16-18;(通常 11,17) 鳞片在侧线上面 9-12(通常 10 或 11), 在 15-19之下;(通常 16 或 17) 在颚骨上的鳞片不存在; 10个孔在下巴上面与后面, 包括在愈合处的两边附近的一个最 smalei 孔, 二个中等大小的孔前腹部地在每个齿骨上, 一个大的孔腹地，中途在齿骨的关节腹地沿着每个齿骨 (通常被密集的乳突遮掩), 与一个大的孔;(二个最后面的孔裂缝状的凹痕迹) 群短的与长的密集乳突而且触须在肉質的下唇，它的較後面的部分上裸露的; 背鰭棘條與臀鰭棘條的形狀強烈地有角的, 通常有角的, 肛門的更強的超過背部的; 身體全黑褐色, 有時有二個不明顯的斜深色條紋，在從後頸到在後胸鰭被下降,第二個從第七到第十背鰭棘的基底的第一個, 彎曲向下到上方或經過側線.(參考文獻 56360)
The species is apparently restricted to river mouths and coastal rocky to sandy bottoms of less than 50 m depth. The smallest specimen (MUFS 22226, 46 mm SL) was collected in a river mouth, while larger specimens were captured by set net or small trawl between 5-50 m depth over rocky or sandy bottoms. Between 1960-1980, the species were observed by Miyazaki SCUBA divers to be solitary and common in small caves, holes, and under overhanging rocks along the Nichinan coast, Miyazaki, southeastern Kyushu Island, from late
summer to winter. However, in recent years (post 1990) the species has been only rarely observed (Ref. 56360).
此鱼种是局限于显然的河口与海岸的岩石对少于 50 公尺深的砂质底部。 最小的标本 (MUFS 22226, 46 mm SL) 在一个河嘴被收集, 然而较大的标本被在 5- 之间的固定网或小的拖网取得了 50 公尺深岩石的之上或砂质底部。 在 1960-1980之间, 此鱼种被宫崎水中呼吸器潜水者观察了是独居性而常见于小的洞穴，洞, 而且在上悬的岩石下面沿着 Nichinan 海岸，宫崎，东南方的九州岛岛, 从迟的
对冬天的夏天。 然而，近几年 (后 1990) 来，此鱼种已经只有很少地被观察。 (参考文獻 56360)
