dc.description.abstractNucleotide sequence data from the mitochondrial 125 rRNA gene were used to evaluate the phylogenetic relationships among the major groups of didelphimorph and paucituberculatan marsupials from South America, the microbiotheriid Dromiciops gliroides, and representatives of four orders of Australasian marsupials. Based on approximately 800 hp in 18 genera, we conclude that the didelphids constitute a monophyletic group with large-sized forms differentiated from small opossums, while Caluromys constitutes the sister taxon to didelphids. The peramelid Isoodon was recovered as the sister taxon to the paucituberculatans Caenolestes and Rhyncholestes, although it is in an uncertain phylogenetic position within the marsupial tree. Dromiciops was recovered as a well-differentiated lineage from South American opossums within the Australidelphian radiation of metatherians that include dasyurid, diprotodontian, and notoryctemorph marsupials.
