Comments: Collected in clear-water creeks and small tributaries of larger rivers, such as the Rio Culuene, Rio Curuá and Rio Teles Pires.  Usually found in shadowed pools between rapids with well-preserved riparian vegetation. Stomachs of 5 specimens from Tapajós and Xingu basins had a predominance of allochthonous items, adults of terrestrial insects (Coleoptera, Curculionidae; Hymenoptera, Formicidae; Diptera), insect aquatic larvae (Trichoptera, Ephemeroptera; Diptera, Chironomidae), fish remains (Characiformes) and plant fragments (Ref. 83482).
