Pleurodema bibroni Tschudi, 1838

(Figs. 7–8)

The characterization of the material at hand by Girard (1858a: 38) and its illustration (Girard 1858b, Pl. IV, Figs. 33–38) match with what is currently known as Pleurodema thaul . This synonymy was first suggested by Donoso- Barros and Cei (1962c), while Donoso-Barros (1969) restricted the name P. bibroni for the Uruguayan populations and P. thaul for the Chileans; for an overview of the nomenclatorial history, see Ferraro & Lavilla (2013).
