简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 21-23; 臀棘 0; 臀鳍软条: 25 - 29. Median depression on head. SL/Body Depth ratio = 3.7-3.8. Origin of dorsal fin in same level or slightly behind anal fin origin. Pectoral fins shorter than head and the extremities reach the origin of the pelvic fins. Small eyes with diameter 6.0-6.8 x head length. Affinities: close to M. ussheri, differentiated by the number of dorsal fins and the eyes which are smaller relative to the head length. M. mento also found in the area of repartition and distinguished by the number of dorsal and anal fins and the number of scales on the lateral line.
在头部上的中动脉凹洼。 SL/体高比 =3.7-3.8. 背鳍起点在相同的水平或些微地在臀鳍起源后面。 胸鳍短于头部而且顶端延伸到腹鳍的起源。 小的眼睛有直径 6.0-6.8个 x 头长。 分类相关: 接近 M. ussheri, 藉由背鳍数目区别了,而且眼那是较小的相对于头长。 M. mento 也发现于分配的区域而且在侧联机藉着背鳍与臀鳍的数字与鳞片的数字区别。
