Eupsophus vertebralis Fig. 3D

Type locality.

Valdivia (Grandison 1961); locality 72 of Fig. 3D.

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).
