FIGURE 10 in A new frog family (Anura: Terrarana) from South America and an expanded direct-developing clade revealed by molecular phylogeny
FIGURE 10. Phylogeny of nobleobatrachian frogs represented by selected species and constructed using sequences from 9 genes. The tree is rooted with Rana temporaria (not shown). Support values (ML bootstrap/Bayesian posterior probability/MP bootstrap) are indicated at nodes. Bayesian and MP support values are not given in cases where those phylogenies conflicted with the ML phylogeny.
FIGURE 9 in A new frog family (Anura: Terrarana) from South America and an expanded direct-developing clade revealed by molecular phylogeny
FIGURE 9. (A) Bayesian and (B) maximum parsimony phylogenies of nobleobatrachian frogs represented by selected genera and constructed using sequences from 17 genes. The trees are rooted with Ranidae (not shown). Support values (Bayesian posterior probabilities or MP bootstrap values) are indicated at nodes.
FIGURE 8 in A new frog family (Anura: Terrarana) from South America and an expanded direct-developing clade revealed by molecular phylogeny
FIGURE 8. Maximum likelihood phylogeny of nobleobatrachian frogs represented by selected genera and constructed using sequences from 17 genes. The tree is rooted with Ranidae (not shown). Bootstrap support values are indicated at nodes. Higher classification is indicated to the right.

FIGURE 5 in A new frog family (Anura: Terrarana) from South America and an expanded direct-developing clade revealed by molecular phylogeny
FIGURE 5. Habitat of Ceuthomantis smaragdinus at 1540 m on Mt. Kopinang, Guyana. The holotype was found about 5 m from the stream in the foreground in Figure 5A; the paratype was found on a leaf about 10 m away from the other side of the stream slightly to the left of the middle of Figure 5B. Photographs by D. B. Means.
FIGURE 11 in A new frog family (Anura: Terrarana) from South America and an expanded direct-developing clade revealed by molecular phylogeny
FIGURE 11. Timetree of nobleobatrachian frogs represented by selected genera and estimated with a Bayesian analysis of sequences from 9 genes, based on a topology obtained from the ML analysis of 17 genes (Figure 8). Numbers on nodes refer to time estimates and credibility intervals of time estimates (Table 2); those in bold are nodes discussed in the text. Illustrations portray the major reproductive modes of the genera and families, with most direct-developing species (i.e., no aquatic larvae) contained in Terrarana (Ceuthomantidae and four other families) that nearly always lay eggs on substrate, and Hemiphractidae that carry their eggs on their backs. Nearly all other nobleobatrachians have aquatic larvae (e.g., tadpoles).
