簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 1; 背的軟條 (總數) : 6; 臀鰭軟條: 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).
與 M. parahybae 與 M. cibelae 藉由比較長的頭部 (29.3-33.8% SL, 對 23.2-27.6 與 25.6-31.1 分別地) 與寬的身體區分了。 (28.5-33.9% SL 對 23.8-27.7 與 25.4-29.8, 分別地) 較小的嘴寬度將此種與 M. eurystoma 區分開。 (50.6-64.3% HL, 對 67.3-84.4)
Reported to reach approximately 9 cm SL (Ref. 81048).
