Discussion of Phylogenetic Relationships
- Brachycephalus ephippium
- Psyllophryne didactyla
Ford and Cannatella (1993) defined Brachycephalidae to be the most recent common ancestor of Brachycephalus and Psyllophryne, and all its descendants. Synapomorphies include the absence of a sternum, digital reduction, and complete ossification of epicoracoid cartilages with coracoids and clavicles (data from Izecksohn, 1971).
Brachycephalids have always been considered to be neobatrachians. A photo in Halliday and Adler (1986:38-39) shows Brachycephalus ephippium in inguinal amplexus, a behavior that is rare in Neobatrachia (Nussbaum, 1980).
