Phylogeny of Raninae (Anura: Ranidae) inferred from mitochondrial and nuclear sequences.
Phylogenetic relationships among representative species of the subfamily Raninae were investigated using approximately 2000 base pairs of DNA sequences from two mitochondrial (12S rRNA, 16S rRNA) and two nuclear (tyrosinase, rhodopsin) genes. Phylogenetic trees were reconstructed using maximum parsimony, Bayesian, and maximum likelihood analyses. Comparison between the nuclear and mitochondrial findings suggested that our final combined data has higher resolving power than the separate data sets. The tribes Stauroini and Ranini formed a sistergroup relationship, and within Ranini, ten major clades were consistently resolved among all analyses based on the final combined data, although the phylogenetic relationships among the ten clades were not well resolved. Our result refuted several previous taxonomic divisions: the genus Pseudoamolops was invalid, and the monophyly of the genera Amolops and Rana were not supported. We suggest elevating Raninae to familial status, and recognizing within the family, at least twelve genera including Staurois, Meristogenys, Clinotarsus, Amolops, Hylarana, Babina, Odorrana, Pseudorana, Rana, Lithobates, Glandirana, and Pelophylax. A broader sampling of species and data from more molecular markers are needed to confidently resolve the phylogenetic relationships among Ranidae.
