Scinax catharinae Clade

DIAGNOSIS: This clade is diagnosed by 90 transformations in nuclear and mitochondrial proteins and ribosomal genes. See appendix 5 for a complete list of these molecular synapomorphies. Morphological synapomorphies suggested for this clade by Faivovich (2002) are absence of the anterior process of the suprascapula, internal vocal sac, distal division of the middle branch of the m. extensor digitorum comunis longus, and insertion of the medial side of this branch on the tendon of the m. extensor brevis medius digiti IV.

COMMENTS: Regardless of problems imposed by the present results to interpretation of the possible synapomorphies of Scinax resulting from Faivovich’s (2002) analysis, the sparse available knowledge on the taxonomic distribution of the transformations supporting the monophyly of the very distinctive S. catharinae clade suggests that most of them still hold in the present analysis. An exception is the m. depressor mandibulae without an origin from the dorsal fascia at the level of the m. dorsalis scapulae, which also occurs in Hyla uruguaya , rendering its optimization ambiguous in our analysis.
