Figure 4; Cryptic coloration and variation of coloration patterns in two undetermined populations of the Eupsophus roseus group A adult females from Pidenco, showing cryptic coloration resembling the forest ground; insets show head profiles of the same individuals B adults and juveniles from Las Lianas exemplifying variation in coloration patterns. Both localities were included as Eupsophus sp. in the map of Fig. 3.
Figure 2; Adult males of Alsodes from the new discovered localities. In parentheses the specific identification according to the phylogenetic analysis (Fig. 3), the snout-vent length (SVL) and code of the respective buccal mucosa sample are indicated. A. Vegas de Cisternas (A. hugoi, SVL = 68.3 mm, VC1m). B. Cajón de Plaza (undetermined, SVL = 54.8 mm, CP5m). C. Vegas de Andrade (A. hugoi, SVL = 57.2 mm, VA1m). D. Vegas de Miranda (A. hugoi, SVL = 56.3 mm, VM6m). E. Cajón Lagunitas (site 3) (A. hugoi, SVL = 71.7 mm, CLP3-5m). F. Lo Aguirre Chico (A. pehuenche, SVL = 52.0 mm, AgCh4m). Some populations are characterized by well-developed interdigital webbing in the hind feet (shown in the insets).
Figure 5; Examples of intrapopulation external variation in adult specimens of the type localities of two species of the Eupsophus roseus group A Eupsophus roseus from Valdivia B Eupsophus migueli from Mehuín. Both examples illustrate the variation in dorsal and ventral (B) coloration, iris color and snout shape.
