Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2; Dorsal soft rays (total): 7 - 8; Anal soft rays: 5 - 6. This species is distinguished from its congeners by the following set of characters: branch of the temporal sensory canal at sphenotic, which gives rise to the supraorbital canal, with two pores; upper tooth plate of branchial arch with three or four series of teeth; small fleshy flat at the corner of the mouth, ventral to the maxillary barbel; dark brown or black patch transversally crossing the orbit, forming a mask like blotch, which can be variably diffuse; distinct color pattern along midline of flank; dorsolateral body plates only with small, irregular, rounded or vertically elongated dark brown or black blotches; ground color of plates typically dusky but not forming large, conspicuous black patches; relatively large, conspicuous dark patch on anterior portion of dorsal fin absent; triangular fleshy flap at the corner of mouth, ventrally to maxillary barbel, not forming an elongated barbel-like structure (Ref. 132450).
Body shape (shape guide): elongated; Cross section: compressed.
Facultative air-breathing; The species inhabits the shallow parts (up to 30 cm deep) of small streams and rivers (1-3 m wide), with slow to moderate water current, fine sand and gravel substrate, and submerged vegetation (132450).
