For over 130 years, the Atlantic Forest antwren  Rhopias gularis  (Spix, 1825) remained known in the Brazilian state of Rio Grande do Sul from 2 undated specimens collected by Hermann von Ihering at Taquara in the early 1880s. We located 1 couple plus 2 lone females along the border with Santa Catarina in the Josafaz stream valley, municipality of Mampituba, in October 2017 and January 2018. These records confirm the present-day occurrence of R. gularis in Rio Grande do Sul and establish a new southern limit of its distribution. We briefly discuss the validity of Ihering’s record and the historical occurrence of the species at Taquara.
