Close Phylogenetic Relationship

We examined phylogenetic relationships among newst of the genus Paramesotriton using partial mitochondrial gene se-quences, including the ND2-tRNATyr region (1415 bp) and the 12S rDNA-tRNAVal -16S rDNA region (1774 bp), from 42individuals of 10 recognized Paramesotriton species and outgroups by Bayesian inference (BI), Maximum likelihood(ML) and Maximum Parsimony (MP) methods. We found that, (1) Laotriton laoensis is the sister group of Paramesotri-ton, (2) the genus Paramesotriton is monophyletic, composed of either the P. caudopunctatus species group and the P.chinensis species group, or the subgenera Allomesotriton and Paramesotriton (3) P. longliensis and P. zhijinensis shouldbe placed in the P. caudopunctatus species group or subgenus Allomesotriton; (4) P. fuzhongensis is not a junior synonym of P. chinensis, and there is a close phylogenetic relationship between P. fuzhongensis and P. guangxiensis.

This is the first molecular systematic treatment of the Prionini. Here, three mitochondrial genes were partially sequenced from the Chinese Prionini to analyze phylogenetic relationships. Nucleotide compositions of three mitochondrial genes in the Chinese Prionini are biased toward A and T as in other insects. Ratios of transition vs. transversion (Ts/Tv) in 12S rRNA decrease with divergence time. However, ratios in 16S rRNA first increase with divergence time but decrease when divergence time is prolonged. Some nodes have poor bootstrap values or Bayesian posterior probabilities in phylogenetic trees reconstructed from single mitochondrial gene. In addition, some conflicting clades are found among phylogenetic trees based on a different gene. Therefore, a single mitochondrial gene provides limited phylogenetic signal and phylogenetic relationships based on a single gene sequence may be questionable. The Chinese Prionini is a monophyletic group. However, the genus Dorysthenes is paraphyletic. Dorysthenes fossatus should be transferred from Dorysthenes but the true status of D. fossatus is currently unknown. Species of Dorysthenes (excluding D. fossatus) constitute a monophyletic clade and there is close relationship between Dorysthenes paradoxus and Dorysthenes zivetta.
