Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 2; Rayons mous dorsaux (Total) : 7; Rayons mous anaux: 12. Distinguished from other species by the following characters: eye diameter 2.2 times in snout length; humeral process triangular, pointed at its tip; absence of axillary pore below the humeral process; 24-26 teeth on lower jaw, number increasing with size; base coloration whitish with large grey-brown blotches on the flanks, leaving only the belly as well as irregular broad white patches in front of and at the end of the adipose fin free; body covered with black-brown dots of about pupil-size (Ref. 78218).
Body shape (shape guide): fusiform / normal.
Collected from a small, seasonal stream and the parent catfishes must migrate upstream from the Ruvu during the rainy season to spawn there (Ref. 78218).
