Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi dorsali molli (totale) : 11; Raggi anali molli: 21 - 22; Vertebre: 33. Differs from all other congeners from northeastern Brazilian drainages by having two vertically elongated humeral blotches, a conspicuous and broad dark midlateral stripe (at least on anterior half of body), body highest along vertical slightly behind midlength of pectoral fin, 31-34 lateral-line scales, and two or three teeth on premaxillary outer series. Other characters important to distinguish this species include: anal fin with 21-22 total rays and 18-19 branched rays; dorsal-fin rays ii,9; 3-6 scales on base of anterior anal-fin rays; one or two maxillary teeth; fins homogeneously darkened by chromatophores; absence of red pigmentation on body when alive (Ref. 81202).

Found at altitude of 212 meters in clear water stream, running over rocky and sandy bottom, with very small pools, 20-70 cm deep (Ref. 81202). Stomach contents of two specimens include filamentous algae, fragments of arthropods and vascular plants, and organic debris (Ref. 81202).

Bayesian length-weight: a=0.01096 (0.00498 - 0.02415), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
