(total): 18 - 19;
soft rays: 6 - 7. This species is distinguished by the following set of characters: teeth properly incisor, even in young; caudal edge of mesethmoid with a unique shape; caudal edge of supraoccipital crest straight, inclined rostrad, its height 27% of postethmoid skull length; width of posterior premaxillary expansion greater than 41% of length of the same bone; arms of articular equal in length; gut S-folded ventrorostrally in adults, anal and medial loops nearly touching; with an abrupt, steep head profile (Ref. 74403).
Inhabits both lakes and rivers. Proliferates in rivers with medium to high velocities. Found between 35 and 535 m elevation (Ref. 36880). Feeds on aufwuchs which cover rocks and submersed trees and filaments of algae.
