Resumen

The brachiopod Glottidia bravardi? is first described from the Paraná Formation (Late Miocene, Argentina). The species was known from other deposits of the “Entrerriense or Paranense” transgression (Puerto Madryn Formation in Argentina and Camacho Formation in Uruguay), and its absence in the Paraná Formation was noteworthy. Finally, two specimens collected around a century ago were found in the Paleoinvertebrate Collection of the Museo Argentino de Ciencias Naturales. One of them was intended to be the holotype of the species, but Glottidia bravardi was formally described just in 1995, by Figueiras & Martínez, based on Uruguayan type specimens. G. bravardi lived in warm, subtropical waters, and its presence in this latitude reflects a northward withdrawal of the genus range in the Atlantic waters during the Paleogene/Neogene, in accordance with other brachiopod examples (i.e., Bouchardia).

Keywords: Brachiopoda, Lingulidae, Glottidia, Late Miocene, Paraná Formation, Argentina.
