Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 8 - 10; Anal soft rays: 6; Vertebrae: 35 - 36. This species is distinguished from all its congeners except teiniagua by the absence of the pores s1, s2, s3, and s6 of the supraorbital line of the laterosensory system (vs. presence of, at least, the pore s6); differs from teiniagua by having the pore i10 of the infraorbital line of the laterosensory system (vs. pore i10 absent) and with 9 pterygiophores in the dorsal fin (vs. 8) (Ref. 122319).
This species inhabits rivers and streams, inhabits rivers and streams with sand- or gravel-bottoms. The species has not been collected with congeners. The stomach of one specimen had immature aquatic insects and unidentified plant remains (Ref. 112319).
