Abstract:

We determined the complete mitochondrial (mt) genome of Rhacophorus dennysi (family Rhacophoridae).The R. dennysi mitogenome (18,052 bp) contained the 37 genes and a single control region (CR) typicallyfound in neobatrachian mtDNAs. In the new mt genome, the ND5 gene and a TLPF tRNA cluster (tRNAThr,tRNALeu(CUN), tRNAPro and tRNAPhe) were located between the CR and the 12S rRNA gene. R. dennysimitochondrial gene rearrangements observed here could be explained by the Tandem Duplication andRandom Loss (TDRL) model. We used twelve mitochondrial protein-coding genes of the newly sequencedand other reported species to assess phylogenetic relationships of Ranoidea. Phylogenetic analyses usingmaximum likelihood (ML) and Bayesian inference (BI) methods supported the sister-group relationshipbetween ((Rhacophoridae + Mantellidae) + Ranidae) and Dicroglossidae. Within Rhacophoridae,two species of the genus Rhacophorus (R. schlegelii and R. dennysi) were clustered together with therepresentative of the genus Polypedates (P. megacephalus), meanwhile, the representative of the genusBuergeria (B. buergeri) occupied the basal position in the clade of Rhacophoridae.
