Diagnosis

M. boehlkei differs from all other species of the genus by the high number of anal fin rays (110-130 vs. 42-88) and by an obtuse angle between rostral fang and frontal profile of skull. It is further distinguished by the following combination of characters: head short, snout blunt, skull length4.2-5.2% TL, rostral fang with dorsal profile slightly concave, anal fin origin below dorsal fin rays number 7-13, pectoral fin 2-3% TL, lower jaw nearly straight, and 6 lateral, subdermal spots of pigmentation (Ref. 34506).
