FIGURE 6. Karyotypes with 2n in A new species of the genus Alsodes (Anura: Neobatrachia) from the Nothofagus forest, Coastal Range, Southern Chile, identified by its karyotype
FIGURE 6. Karyotypes with 2n = 26 (A) Alsodes valdiviensis with comparative purposes. Reformed from that of (B) Alsodes norae (2n = 30), and (C) A. barrioi (2n = 34) by means of hypothetic mechanisms of chromosome evolution in some Alsodes species. In B and C small numbers beside some chromosomes indicate the original chromosome position procedence.

FIGURE 1. Specimens of Alsodes cantillanensis sp. nov. (A, holotype, SSUC-Am-168) and A. nodosus (B, adult male, not captured) from Quebrada Infiernillo. C and D show details of the irises of A. cantillanensis and A. nodosus, respectively.

FIGURE 4. Bayesian inference consensus tree (50% majority-rule) showing the position of the new species, Alsodes cantillanensis (in bold), within the genus. Numbers next to the nodes, separated by slashes, correspond to bootstrap values of maximum parsimony analysis, treating gaps as a fifth state, and posterior probability of Bayesian inference, respectively.

Figure 2 from: Correa C, Zepeda P, Lagos N, Salinas H, Palma RE, Vásquez D (2018) New populations of two threatened species of Alsodes (Anura, Alsodidae) reveal the scarce biogeographic knowledge of the genus in the Andes of central Chile. Zoosystematics and Evolution 94(2): 349-358. https://doi.org/10.3897/zse.94.25189
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 1 New and literature records of Alsodes from the Andes Range between 34°50' and 38°05'S. Yellow circles represent the new localities reported in this study; squares represent type localities. A. Andean localities of Alsodes of the literature between 34°50' and 38°05'S: the southernmost localities of A. montanus and A. tumultuosus, the type locality of A. hugoi, localities of A. pehuenche (within red box B, see map B) and the type locality of A. vittatus. There is a record of a putative new species related to A. nodosus in Pemehue (Alsodes sp. 1 of Blotto et al. 2013; not included in the map), presumably the same type locality of A. vittatus. Red boxes correspond to the three explored areas described in this study (maps B, C and D). B. Area explored during the first field campaign (Paso Pehuenche, Laguna del Maule and surroundings). All colored symbols correspond to localities of A. pehuenche: yellow circles correspond to new records; green circles and the square are all previously known localities of the species. The white circle is the place where no amphibian was found. C. Area and sites explored during the third field campaign (tributaries of the Guaiquivilo River). D. Area and sites explored during the second field campaign (surroundings of Laguna El Dial). See details of the localities and the populations discovered in Table 1. Orange lines represent the boundary between Chile and Argentina; thinner yellow lines indicate the boundaries of the administrative regions of Chile.

Figure 3 Bayesian consensus tree (50% majority-rule) showing the relationships of the new Andean populations of Alsodes. Representatives of the new populations are labeled in green (related to A. pehuenche) and red (related to A. hugoi) (see details of the new localities in Table 1). Note that specimens from Cajón de Plaza are distributed in both the red and green clades. Reference sequences of the type localities of A. pehuenche and A. hugoi are in bold. Numbers next to the nodes correspond to posterior probabilities (only values ≥ 0.95 of the more internal nodes are shown). The scale bar in the lower left corner represents the expected substitutions per site along the branches.
