FIGURE 1 in Description and phylogenetic relationships of a new trans-Andean species of Elachistocleis Parker 1927 (Amphibia, Anura, Microhylidae)

FIGURE 1. Phylogenetic relationships of the subfamily Gastrophryninae. Best maximum-likelihood tree obtained from analyses of DNA sequences of mitochondrial (12S, 16S and CO1) and nuclear (BDNF, cmyc2, H3A, 28S, SIA1, and Tyr) genes from 302 terminals and up to 6171 bp. Blue numbers below branches are ML bootstrap support values. Voucher number and GenBank accession number for the 16S gene are shown for each specimen. Outgroup and other subfamilies are not shown. The complete phylogeny is available in Zenodo.org under HTTPS://DOI.ORG/10.5281/zenodo.3723213.

FIGURE 2. Phylogenetic tree reconstructed by Bayesian inference (BI) for the concatenated mitochondrial and nuclear DNA (cox1, 16S, and ANT) sequence dataset. Nodal supports (i.e., posterior probability values from BI analysis and ultrafast bootstrap support values from maximum likelihood analysis) are shown as percentages along the branches. The tree is rooted with Quadrula quadrula. Major clades are annotated. Colored box along clades corresponds to the target taxa (blue, Popenaias popeii; green, P. ganina; orange, P. berezai n. sp.).
