This monotypic genus occurs in the upper Orinoco drainage. Ecological and behavioral data are unavailable. Although it has been placed within the Pseudohemiodon ZBK group based on its strongly depressed body, its filamentous lips with long fringed barbels, and its spoon shaped and size reduced dentition, Dentectus ZBK 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 distinguish it from all other genera.
