 The two species and their hybrids are hard to distinguish, but "L. bocagei" has a shorter and wider head, and the last unbranched ray of the dorsal fin has a shorter denticulated section but with more densely packed denticles.In the first two traits the hybrids are intermediate between their parent species, in the latter they are closer to "L. comizo".Also, the two species are distinguished by their microhabitat preferences where they are sympatric, with "L. comizo" inhabiting almost stagnant parts of the river.
