We present a mitochondrial gene tree for representative species of all the genera in the subfamily Myobatrachinae, with special emphasis on Crinia and Geocrinia. This group has been the subject of a number of long-standing taxonomic and phylogenetic debates. Our phylogeny is based on data from approximately 780 bp of 12S rRNA and 676 bp of ND2, and resolves a number of these problems. We confirm that the morphologically highly derived monotypic genera Metacrinia, Myobatrachus, and Arenophryne are closely related, and that Pseudophryne forms the sister group to these genera. Uperoleia and the recently described genus Spicospina are also part of this clade. Our data show that Assa and Geocrinia are reciprocally monophyletic and together they form a well-supported clade. Geocrinia is monophyletic and the phylogenetic relationships with the genus are fully resolved with two major species groups identified: G. leai, G. victoriana, and G. laevis; and G. rosea, G. alba, and G. vitellina (we were unable to sample G. lutea). We confirm that Taudactylus forms the sister group to the other myobatrachine genera, but our data are equivocal on the phylogenetic position of Paracrinia. The phylogenetic relationships among Crinia species are well resolved with strong support for a number of distinct monophyletic clades, but more data are required to resolve relationships among these major Crinia clades. Crinia tasmaniensis and Bryobatrachus nimbus form the sister clade to the rest of Crinia. Due to the lack of generic level synapomorphies for a Bryobatrachus that includes C. tasmaniensis, we synonymize Bryobatrachus with Crinia. Crinia georgiana does not form a clade distinct from other Crinia species and so our data do not support recognition of the genus Ranidella for other Crinia species. Crinia subinsignifera, C. pseudinsignifera, and C. insignifera are extremely closely related despite differences in male advertisement call. A preliminary investigation of phylogeographic substructure within C. signifera revealed significant divergence between samples from across the range of this species.
