Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 2; Rückenflossenweichstrahlen (insgesamt) : 8; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 5. This species is distinguished from its congeners by the following set of characters: 20 or 22 dorsal procurrent caudal-fin rays; 30-32 interopercular odontodes; 26-28 premaxillary teeth; 27-32 dentary teeth; medial margin of the autopalatine slightly sinuous; sesamoid supraorbital lacking a lateral projection; anterior portion of the mesethmoid just posterior to cornu base relatively broad; dorsal process of the opercle stick-shaped; anterior portion of the preopercle not distinctively elongated; parurohyal foramen rudimentary; and posterior process of the parurohyal long, its length about three quarters of lateral process length (Ref 138050).
Body shape (shape guide): elongated; Cross section: oval.
This species inhabits moderate flowing streams 50 cm deep and about 2 m wide, with a substrate composed of pebbles and sand (Ref. 138050).
