Geographic distribution.

The two undescribed species mentioned in the recent literature ( Fig. 1 ) are known from one locality each: Tolhuaca ( Eupsophus sp. 2 of Blotto et al. 2013) and Villarrica ( Eupsophus sp. of Suárez-Villota et al. 2018b) (both considered as E. roseus by Correa et al. 2017). Also, a series of populations located between 36°10' and 38°15'S, assigned to E. roseus by Correa et al. (2017), should be included here since they occupy intermediate phylogenetic and geographic positions among the species recognized by Suárez-Villota et al. (2018b). Almost all these localities are within the latitudinal limits defined for E. roseus according to historical records (see above), but as Correa et al. (2017) indicated, these populations cannot identify unambiguously to species level by their external characters. Other southernmost undetermined populations included in Correa et al. (2017) (Santa Amelia, Pumalal, Puringue and Malalhue) are considered here as E. roseus because they make up a well-supported monophyletic group with specimens from the type locality of that species (where the specimen from Naguilán is also included). The two new localities where phenotypic observations were done for this review (see below) are also included here.

Figure 1. Composition of the genus Eupsophus between 1961 and 2018 according to several reviews and studies. Year of species description is provided in parentheses. Capurro (1958) and Cei (1958, 1960, 1962 a, 1962 b) recognized the same two species of Grandison (1961), but with different names (see comment in Cei 1962 b). † Revalidated by Formas and Vera (1982) (removed from the synonymy of E. roseus). ‡ Undescribed species from Isla Wellington (Chile), sister to E. calcaratus. § It appears as Eupsophus sp. 1 in Blotto et al. (2013). | Probable undescribed species from Tolhuaca (Chile), sister to E. roseus. ¶ Putative species from Villarrica (Chile), sister to E. roseus.

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.
