Short description Morphology | Morphometrics

Dorsal soft rays (total): 10. Distinguished from all congeners by the following combination of characters: 15-20 branched anal-fin rays; four or five scales in transverse series from the dorsal-fin origin to the lateral line; shallow body (depth 23.6-30.6% of SL); 37-43 perforated lateral line scales; first, third and fifth or, more rarely, first and fourth outer premaxillary tricuspid teeth projecting anteroventrally; two to five tricuspid to pentacuspid maxillary teeth, followed by five to seven smaller conical to tricuspid teeth; conspicuous dark, vertically elongated humeral spot, extending to below the lateral line; dark dorsal stripe extending from supra-occipital spine to the caudal peduncle with a gap at the adipose-fin base; caudal-fin lobes without conspicuous markings, uniformly pigmented along rays; no hooks on the pelvic and anal-fin rays in mature males (Ref. 54761).

Biology     Glossary (e.g. epibenthic)

Found in Ribeirão Santa Barbara, the type locality, which has two distinct reaches: a lentic pool which is 23-49 m wide, 1.5 m deep, with a water velocity of 0.4 m/s, over a gravel bottom and some smaller areas with sand or mud; and a rapid located further upstream, which is 6.2-13.5 m wide, 0.5 m deep, with a greater water velocity of 1.1 m/s and a rocky bottom. Both stretches have margins with altered riparian forest or herbaceous vegetation (Ref. 54761).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.7   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
