We investigated the evolutionary relationships among these frogs using 2.3kb from the 12S and 16S rRNA mitochondrial genes. Maximum parsimony, Bayesian inference, and maximum likelihood methods all largely agree, confirming the groups monophyly and revealing many weaknesses in current taxonomy and understanding of the systematics of the group. Results of phylogenetic analyses suggest that (1) currently recognized Papuan subfamilies, Genyophryninae and Asterophryinae, should be combined into the Asterophryinae; (2) currently recognized genera Cophixalus and Callulops are polyphyletic, and (3) previous phylogenetic hypotheses can be refuted with these new molecular data. Genetic divergence within Papuan microhylids is tremendous compared to that within other frog families. We hypothesize this to be primarily due to a relatively high rate of molecular evolution during adaptive radiation.} }
