This dataset contains the digitized treatments in Plazi based on the original journal article Pereira, Edson H. L., Reis, Roberto E. (2022): A new dwarf armored catfish Pareiorhaphis (Loricariidae: Hypoptopomatinae) from the Uruguai River basin, Southern Brazil. Neotropical Ichthyology (e 220049) 20 (3): 1-14, DOI: 10.1590/1982-0224-2022-0049, URL: dx.doi.org/10.1590/1982-0224-2022-0049 A new, very distinctive species of Pareiorhaphis is described from the rio Uruguai basin, in Rio Grande do Sul State, southern Brazil.

Pareiorhaphis pumila, new species, is a small bodied hypoptopomatine catfish with a maximum standard length barely reaching 50 mm. The specimens were captured from rock-bottomed habitats in various localities in the rio Ijuí basin. Despite occurring in rock-bottomed fast-flowing headwater stream tributaries as the other species of Pareiorhaphis, this is the first species collected also in the main channel of the middle stretch of a large tributary to the rio Uruguai.
