Resumen:
The genus Homonota was described by Duméril & Bibron in 1886 , and currently includes eight described species: Homonota borellii , H. uruguayensis , H. fasciata, H. darwinii , H. underwoodi, H. andicola , H. whitii & H.rupicola and one subspecies of H. darwinii ( H. darwinii macrocephala ) . It is distributed from 15º south in southern Brazil, Bolivia, Paraguay, Uruguay and Argentina to 54º south in Patagonia, across multiple different types of habitats. In Chile there are three related species previously considered as Homonota : Garthia gaudichaudii , G. dorbignyi , G. penai . Several morphological systematic studies have been completed, but for three widely distributed species in Argentina ( Homonota darwini , H. underwoodi & H. fasciata ), few data are available. No phylogeographic studies or molecular phylogenetic hypotheses are available for the genus. The objective of this work is to present a molecular phylogenetic hypothesis for most of the described species in the genus, plus eight candidate species. We sequenced two mitochondrial genes (cyt- b & 12S) and seven protein nuclear coding and four nuclear anonymous loci, and implemented traditional concatenated analyses as well as species tree approaches. We discuss the taxonomic implications of these results and how the future integration of phylogeographic and morphological approaches will allow further testing of demographic and biogeographic hypotheses.
