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]
