New morphological synapomorphies for the new world direct-developing frogs (Amphibia: Anura: Terrarana)

The New World direct-developing frogs (Terrarana) comprise more than 970 species distributed from the southern United States to northern Argentina. Although the composition of this clade has been remarkably stable for many decades, evidence for its monophyly is derived mostly from DNA sequences with...

description The New World direct-developing frogs (Terrarana) comprise more than 970 species distributed from the southern United States to northern Argentina. Although the composition of this clade has been remarkably stable for many decades, evidence for its monophyly is derived mostly from DNA sequences with putative phenotypic synapomorphies limited to the occurrence of direct development, an embryonic egg tooth (known in few species), and T-shaped terminal phalanges. Based on a survey of the urogenital and vascular systems and the submandibular musculature of hyloid frogs, we report 16 characters that provide putative synapomorphies at a variety of hierarchic levels.
