Rhyacoglanis is a genus of catfishes (order Siluriformes) of the family Pseudopimelodidae.[1]

Species

There are 9 species in the database, and the other 3 haven't been described, so they won't be included.[2]

Identification

Rhyacoglanis is distinguished from other Pseudopimelodidae by three synapomorphies: the presence of a light blotch on the cheek; a connection between the middle of the dark caudal-fin stripe and the dark caudal-peduncle pigmentation; and 30–35 total vertebrae.[2]

Distribution

Rhyacoglanis genus is widely distributed in the cis-Andean portions of South America, mainly in the Amazon, Orinoco, Paraná, Paraguay, and lower rio Tocantins basins.[1]
