Gymnotus carapo
Gymnotus carapo
Key differences: G. carapo typically has more numerous and often less distinct vertical bands, which may be more irregular or broken. The head shape and body proportions can also differ subtly, with G. inaequilabiatus often having a more robust head relative to its body length.
Gymnotus coatesi
Gymnotus coatesi
Key differences: G. coatesi generally has a more uniform coloration, often lacking the prominent banding seen in G. inaequilabiatus, or having very faint, irregular markings. Morphological measurements, particularly of head length and body depth, are crucial for definitive differentiation.
