Pachymedusa Duellman, 1968

TYPE SPECIES: Phyllomedusa dacnicolor Cope, 1864 .

DIAGNOSIS: Molecular autapomorphies include 105 transformations in nuclear and mitochondrial proteins and ribosomal genes. See appendix 5 for a complete list of these transformations. Possible morphological autapomorphies are the first toe opposable to others, reticulated palpebral membrane (homoplastic with some species of Phyllomedusa ; Duellman et al., 1988b), and the iris reticulation (Duellman, 2001).

COMMENTS: Duellman (2001) also includ­ ed the toes about one­fourth webbed as an autapomorphy of Pachymedusa . In the context of our results, this is probably not an autapomorphy, as the webbing is also equally or more reduced in Hylomantis (as redefined here), Phasmahyla , and Phyllomedusa .

CONTENTS: Monotypic. Pachymedusa dacnicolor (Cope, 1864) .

Phasmahyla Cruz, 1990

TYPE SPECIES: Phyllomedusa guttata A. Lutz, 1924 , by original designation.

DIAGNOSIS: The monophyly of this genus is supported by 94 transformations in mito­

chondrial protein and ribosomal genes. See appendix 5 for a complete list of these molecular synapomorphies. Possible morphological synapomorphies of this genus are the absence of a vocal sac, and the modification of the larval oral disc into an anterodorsal funnel­shaped structure (Cruz, 1990).

COMMENTS: Cruz (1990) mentioned the absense of parotoid glands in Phasmahyla but stressed the presence of a pair of latero­dorsal glands. While these glands could be cosidered as possible synapomorphies of Phasmahyla , additional work is needed in order to determine if they could be considered as homologous to the parotoid glands present in Phyllomedusa .

CONTENTS: Four species. Phasmahyla cochranae (Bokermann, 1966) ; Phasmahyla exilis (Cruz, 1980) ; Phasmahyla guttata (A. Lutz, 1924) ; Phasmahyla jandaia (Bokermann and Sazima, 1978) .
