Comments: This species was found hidden in crevices within laterititic bedrock substrate covered by alluvial sediment, typical of the median portion of the Araguaia River basin and were manually collected and sometimes it was necessary to break the rocks to remove specimens that were hidden. The laterite is a geomorphological formation that originates from the weathering of lateritic crusts that cover the geological units, and is common at the middle and lower rio Araguaia stretches. Several species of Siluriformes that occur syntopically with this species were also collected: <i>Centromochlus schultzi, Tatia intermedia, Auchenipterichthys longimanus, Rhinodoras boehlkei, Platydoras armatulus, Rhamdia quelen, Leporacanthicus galaxias, Peckoltia vittata, P. sabaji, Parancistrus aurantiacus, Pseudacanthicus</i> sp., and <i>Spectracanthicus javae</i>. Specimens were collected in the twilight and daytime, with most of these collected during the morning and at periods of capture, the collected specimens were in lethargic condition (Ref. 123897).
