Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 12 - 14; Duri dubur: 0; Sirip dubur lunak: 9 - 10; vertebrata, bertulang belakang: 37. Diagnosis: 50-53 (Ref. 81638) or 46 (Ref. 26632) scales in lateral line. 6-7 anal fin branched rays; dorsal portions of body with distinct dark, vertically oriented dark marks that form saddle-shaped pigmentation pattern; prominent horizontally elongate, dark spots on mid-lateral surface of body (Ref. 81638).
Body shape (shape guide): elongated; Cross section: compressed.

Found under rocks, in riffles of moderately large rivers (30-50m) in the savannah zone, in areas where there is a strong current (>1m/sec); in all sites where collection took place, there was a rather restricted gallery of shrubs and small trees on the river banks; water was greenish with a transparency of about 50 cm, neutral pH (6.5-7.5), with a high content of dissolved oxygen (6.5-7.5 mg/l) and a rather low conductivity (35-45 µS/cm); water temperatures were between 23 and 25 °C at noon (Ref. 26632).
