Collected under dense forest vegetation commonly found in central Amazon upland areas with Mauritia flexuosa palm trees. The collection site is characterized by black water with high transparency, width of up to about 2 m and depth at the stream bed up to about 0.5 m. Mostly encountered in adjacent pools and next to palm-tree roots, where depth was about 0.1 m or less (Ref. 95522). Costa, W.J.E.M. and H.

It also differs from all congeners by the possession of hypertrophied teeth on the anterior part of the outer row of the premaxillary and dentary in males (vs. teeth never hypertrophied) (Ref. 95522).Description: longitudinal series of scales 29-30; transverse series of scales 6; Costa, W.J.E.M. and H.
