Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 2; Radios blandos dorsales (total) : 8; Espinas anales: 2; Radios blandos anales: 5. This species is distinguished from its congeners by the following set of characters: laminar, triangular dorsal process of opercle; 13-15 dorsal procurrent caudal-fin rays; 33-36 interopercular odontodes; 18-22 premaxillary teeth, and 23-25 dentary teeth; medial margin of
the autopalatine sinuous; sesamoid supraorbital without a lateral projection; anterior portion of the mesethmoid just posterior to cornu base relatively narrow; parurohyal foramen rudimentary or lacking; posterior process of the parurohyal relatively short, less than half lateral process; and S4 pore about equidistant from S3 and S6 pores (Ref 138050).
Body shape (shape guide): elongated; Cross section: oval.
This species inhabits clear, moderately flowing streams, with a substrate composed of pebbles and cobbles (Ref. 138050).
