Descripción breve
Claves de identificación | Morfología | Morfometría
Radios blandos dorsales (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).
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).
