Summary Here the length–weight relationships (LWRs) of two catfish species are provided. Individuals of Imparfinis mirini Haseman, 1911, and Phenacorhamdia tenebrosa (Schubart, 1964) were collected in August and December 2017 from the Guareí River Basin, upper Paraná River basin, Brazil. Values of b were between 2.66 and 3.11 and a between 0.0122 and 0.0137; statistical analysis showed high r 2 values. Lastly, a new record of maximum standard length for P. tenebrosa is provided.
