Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 7; Rayons mous dorsaux (Total) : 7; Épines anales: 1; Rayons mous anaux: 7. Color pattern consists of many narrow dark horizontal lines on the sides (one per scale row), generally light brown bands alternating with dark brown midlateral stripes, and the caudal fin is always spotted, alternating white and brown bands. Distinguished from Belobranchus segura by the combination of the following characters: 27-35 scales in transverse forward series (vs. 22-28); 21-34 predorsal scales (vs. 16-23); 20-23 transverse back series (vs. 18-21); head length 29-36% of SL (vs. 26-31% of SL) and predorsal length 40-46% SL (vs. (38-42 % SL) (Ref. 91761).
