Descripción
We studied
the skulls of eleven species of Philodryas. The skull of Philodryas
patagoniensis is described, and some characters that show interspecific
variation are recognized. These characters are used for phylogenetic inferences.
We obtained three trees using Hennig86. The pair of sister species wich is
presented in the three cladograms is P. mattogrossensis - P. varius: in only
ene tree: P. buroni - P. burmeisteri.
