Geographic distribution.

It is known mainly in the coastal zone of Chile, between the north of the Nahuelbuta Range (37°19'S) and the Osorno coast (40°49'S). Only two localities outside this area are known, Tolhuaca (locality 26), on the western margin of the Andes, and Puerto Blest in Argentina (107; Basso and Úbeda 1999, Úbeda and Basso 2012a), on the other side of the Andes. However, this last point is closer to the records of E. emiliopugini . Eupsophus vertebralis and E. emiliopugini would have allopatric distributions according to Formas (1989) and Nuñez (2003), but two relatively recent records of E. emiliopugini (Raulintal and Pucatrihue, Olivares et al. 2014 and Suárez-Villota et al. 2018b, respectively; Fig. 3D ) imply the sympatry of both species in the southern end of the distribution of E. vertebralis . The maps of Rabanal and Nuñez (2008) and IUCN (2019) also imply sympatry areas in Chile, but in different zones: on the Coastal Range according to Rabanal and Nuñez (2008) and on the western foothills of the Andes according to IUCN (2019). None of those sympatry areas is supported by the review of the literature records ( Fig. 3D ).

Figures

Figure 3. Compilation of localities of Eupsophus species gathered from the literature (see the complete list of localities in Appendix 1). Multicolored circles and the star indicate localities where two or three species of the same group have been reported in the same or different sources. White circles indicate the localities where two undescribed species have been identified (Villarrica and Tolhuaca), two undetermined populations included in this study (Fig. 4) and several ones considered by Correa et al. (2017) as E. roseus, whose taxonomic status is uncertain according to the current taxonomy (Suarez-Villota et al. 2018 b). Thin gray lines within Chile represent boundaries of Administrative Regions.
