Systematics of the Ctenosaura group of lizards (Reptilia : Sauria : Iguanidae)

The phylogenetic relationships of the species of the genus Ctenosaura were analysed using two independent data sets derived from morpho-etho-ecologica l and genetic (RAPD) markers. The analysis of the data matrix based on morp ho-etho-ecological characters yielded a consensus tree with the species of Ctenosaura forming three clades. The consensus tree based on the RAPD data is not as well resolved as the morphological tree. Subgeneric status is pro posed for the three monophyletic subgroups within the tnunophyletic genus C tenosaura.
