简单描述
检索表 | 型态特徵 | 形态测量图
背棘 (总数) : 1; 背的软条 (总数) : 6; 臀鳍软条: 9 - 12; 脊椎骨: 30. Distinguished from M. parahybae and M. cibelae by the longer head (29.3-33.8% SL, versus 23.2-27.6 and 25.6-31.1 respectively) and wide body (28.5-33.9% SL versus 23.8-27.7 and 25.4-29.8, respectively). The smaller mouth width distinguish this species from M. eurystoma (50.6-64.3% HL, versus 67.3-84.4).
与 M. parahybae 与 M. cibelae 藉由比较长的头部 (29.3-33.8% SL, 对 23.2-27.6 与 25.6-31.1 分别地) 与宽的身体区分了。 (28.5-33.9% SL 对 23.8-27.7 与 25.4-29.8, 分别地) 较小的嘴宽度将此种与 M. eurystoma 区分开。 (50.6-64.3% HL, 对 67.3-84.4)
Reported to reach approximately 9 cm SL (Ref. 81048).
