Phylogenetic Relationships Within the Genus Potorous (Marsupialia: Potoroidae) Based on Allozyme Electrophoresis and Sequence Analysis of the Cytochrome b Gene

  • Elizabeth A. Sinclair

Controversy over the taxonomic designations within the genus Potorous has highlighted problems associated with using only morphological data. The recent rediscovery of Gilbert's Potoroo has allowed us to reexamine the relationship of this species to other extant potoroos. Phylogenetic relationships and estimated divergence times are presented, based on electrophoretic and cytochrome b sequence data. There was considerable concordance between the data sets. We conclude that Gilbert's Potoroo is a separate species and should be referred to by its original name, Potorous gilbertii (Gould 1841). Estimates for potoroid divergences are in line with those of Flannery (1989).
