[1][2] This species is endemic to Venezuela where it is found in the upper Orinoco drainage.

[1] There is very little ecological and behavioral information on this species.

[1] This species reaches 13.7 centimetres (5.4 in) SL.

[3] Although it has been placed within the Pseudohemiodon group based on its strongly depressed body, filamentous lips with long fringed barbels, and small, spoon-shaped and dentition, Dentectus also shows unique derived features such as the presence of plates along the outer margin of its maxillary barbels, and a unique mouth structure that distinguishes it from all other genera.
