Mussurana quimi is a species of Pseudoboini known from central, southeastern, and southern Brazil, Paraguay, and northeastern Argentina. We report the occurrence of this species in the state of Rio Grande do Sul, Brazil, based on two specimens from Santa Maria municipality. This report extends this species’ distribution about 950 km south from its type locality and 330 km south from the nearest previous locality record (Posadas, Argentina). It also represent new southernmost records for M. quimi. We also provide brief comments on coloration and morphological variation of this species as well as an updated distribution map.
