All Fishes Data Sheet
Scientific Name	Rhyacoglanis sp. `ARAGUAIA`
Common Name
Etymology	Rhyacoglanis, from the Greek rhyax = torrent + glanis = catfish; indicating a catfish inhabiting running waters in reference to the habitat of the genus. Gender masculine.
Species Information
Identification	Rhyacoglanis is distinguished from other Pseudopimelodidae by three synapomorphies: 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. A key to the species is located HERE.
General Remarks	This Rhyacoglanis from the the upper Rio Araguaia and Rio Das Mortes was originally reported as R. pulcher when a specimen's COI gene sequence was uploaded to GenBank by E.R.M. Martinez et al. [2007. Molecular phylogeny of Pseudopimelodidae (Teleostei: Siluriformes). Submitted (SEP 2007) to the EMBL/GenBank/ DDBJ databases]. Subsequent genetic testing by J. Chuctaya et al. [2023. PLoS ONE, 18(7): e0287120] of newly collected, confirmed R. pulcher revealed that this fish is not R. pulcher, but instead may be an undescribed new species.
