Rhinoderma
Darwin's Frogs
David Cannatella- Rhinoderma darwinii
- Rhinoderma rufum
Introduction
The genus is known from the temperate forests of southern Chile and Argentina. The frogs are small, about 30 mm long. In Rhinoderma darwinii, the males carry the tadpoles in their vocal sacs, and development is completed as froglets. Were it not for the unusual mode of development Rhinoderma would be considered a leptodactylid. There are no fossils.Geographic Distribution
The distribution of living members of the family Rhinodermatidae is indicated in red.
Discussion of Phylogenetic Relationships
Ford and Cannatella (1993) defined the name Rhinoderma for the node that is the last common ancestor of Rhinoderma rufum and R. darwinii. The family-group name Rhinodermatidae is redundant with Rhinoderma. Rhinoderma is diagnosed by rearing of the larvae in the vocal sac of the male, and recognition of the taxon as a family is based on this apomorphy. The known derived characters of Rhinoderma (Lynch, 1971) do not clarify its relationships.References
