Cerdocyonina is a taxonomic rank which represents the South American sub-tribe of the Caninae (the canines), and is sister to the wolf-like sub-tribe Canina.[2] Its members are colloquially known as the South American canids.[3]
Taxonomy
Morphological and DNA evidence shows that the South American canids, being the most diverse group of canids on any continent, forms its own natural group.[3]
These taxa, representing diverse adaptations, can be diagnosed by the following synapomorphies: angular process of the mandible wide, may lack hooklike termination, expansion accommodates widened insertions for pterygoid muscle segments, especially that for the medial branch of the internal pterygoid; posterior cusp of p3 weak or absent; and m1 hypoconid and entoconid, joined by cristids.
The cladogram below is based on the phylogeny of Lindblad-Toh et al. (2005),[4] modified to incorporate recent findings on Lycalopex species[5] and Dusicyon.[6]
