Dentectus barbarmatus

Dentectus barbarmatus is the only species of the monotypic genus Dentectus, a genus of armored catfish. [2] [3]

This species is endemic to Venezuela where it is found in the upper Orinoco drainage. [2] There is very little ecological and behavioral information on this species. [2]

This species reaches 13.7 centimetres (5.4 in) SL. [4] 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. [2]
