This dataset contains the digitized treatments in Plazi based on the original journal article Shibatta, Oscar Akio, Benine, Ricardo Cardoso (2005): A new species of Microglanis (Siluriformes: Pseudopimelodidae) from upper rio Paraná basin, Brazil. Neotropical Ichthyology 3 (4): 579-585, DOI: 10.1590/S1679-62252005000400015, URL: scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252005000400015&lng=en&tlng=en Microglanis garavelloi, new species, collected in tributaries of rio Paranapanema and rio Tietê, is the first species of the genus described from upper rio Paraná basin.

The new species can be distinguished from other species of Microglanis on morphometric characters, color pattern, caudal-fin shape, pectoral-spine morphology and lateral line development. Characters used specifically to distinguish M. garavelloi from M. cottoides (laguna dos Patos and rio Uruguay basins) and M. parahybae (rio Paraíba do Sul basin) include morphometrics, color pattern and pectoral-spine serration. Microglanis garavelloi, espécie nova, coletado em tributários do rio Paranapanema e rio Tietê, é a primeira espécie do gênero descrita da bacia do alto rio Paraná.
