简单描述
检索表 | 型态特徵 | 形态测量图
Body moderately firm, slightly compressed body. Dorsal and ventral coloration dark; fins dark distally. Caudal peduncle rather elongate (ca 2.2 times greatest horizontal length of D1 including spine, about 1/5 TL). Mouth relatively broad, 1.4 times eye length. Upper eyelid with pale naked patch. Denticles short, robust, arranged in regular rows. Flank-marking posterior branch truncate and merging ventrally with post-pelvic marking. Anterior part of caudal base marking very broad, enveloping ventral surface and extending to flanks; central caudal oval, well separated from caudal base marking; upper caudal marking straight . Monospondylous centra 40 (Ref. 45056).
身体一般结实又些微扁长形的身体。 背部与腹的颜色深色的; 鳍深色的末梢部地。 尾柄相当延长。 (ca 2.2 倍最大水平 D1 的长度 1根包括棘 , 大约 1/5 TL) 嘴相当宽的,1.4 倍眼径。 上眼睑有灰白的裸露区块。 细齿短的，结实的, 排列成整齐的列。 侧面的斑纹在后部分支截形而且与在腹鳍之后的斑纹垂直地合并。 尾部基底的斑纹的前部非常宽的, 包住腹面而且延伸至侧面; 中央的尾部椭圆形, 与尾部基底的斑纹分得很开; 上尾部的斑纹直线。 Monospondylous 中心 40.(参考文献 45056)
