Figures & data

Table 1. Geographical coordinates for all populations know of Alsodes coppingeri in Chile and new records from Argentina. Type locality in bold. From Chile also was reported in Puyuhuapi, Aysén Province [14], and Península Muñoz Gamero, Última Esperanza Province [19], but both localities require new studies

Figure 1. Known geographic distribution of Alsodes coppingeri. Records from Chile: 1) Puerto Río Frío (type locality), 2) Caleta Lever, 3) Caleta Tortel, 4) Puerto Yungay, 5) Laguna Caiquenes, 6) Canal Michel, and 7) Villa O’Higgins. New records from Argentina: 8) Cerro Vespignani, 9) Lago del Desierto, and 10) Salto del Anillo. See geographical coordinates in .

Figure 4. Phylogenetic analysis of Alsodes. Most parsimonious tree of 767 steps obtained with TNT. Branch lengths are proportional to the number of transformations, except when indicated by numbers. On the nodes parsimony jackknife supports are indicated. The new records from Argentina are denoted in bold.
