Phylogenetic relationships among Rhacophorinae (Rhacophoridae, Anura, Amphibia), with an emphasis on the Chinese species

The partial nucleotide sequence of mitochondrial 12S and 16S rRNA genes was determined for 23 Chinese species of Rhacophoridae (Amphibia: Anura), representing four of the eight recognized genera. Using Buergeriinae as the outgroup, phylogenetic analyses (maximum parsimony, maximum likelihood, and Bayesian inference) were performed in combination with already published mitochondrial 12S and 16S sequences of Rhacophorinae frogs. In all cases, Philautus romeri Smith, 1953 is recovered as the sister taxon to all other Rhacophorinae, although the support values are weak. Chirixalus doriae Boulenger, 1893 is closer to Chiromantis [ Chiromantis rufescens (Günther, 1868) and Chiromantis xerampelina Peters, 1854] than to Chirixalus vittatus (Boulenger, 1887). The clade { Philautus odontotarsus Ye & Fei, 1993, [ Philautus idiootocus (Kuramoto & Wang, 1987), Kurixalus eiffingeri (Boettger, 1895)]} is recovered with strong support. The monophyly of Theloderma and Rhacophorus rhodopus Liu & Hu, 1959 is not supported. It is suggested that Philautus albopunctatus Liu & Hu, 1962 should be placed into the synonymy of Theloderma asperum (Boulenger, 1886), and that Philautus rhododiscus Liu & Hu, 1962 should be assigned to Theloderma , so as to correct the paraphyly. Additionally, the monophyly of ‘ Aquixalus ’ is not supported, and this requires further examination. Results also indicate that the Rhacophorus leucomystax (Gravenhorst, 1829)/ Rhacophorus megacephalus (Hallowell, 1861) complex needs further revision. Studies employing broader sampling and more molecular markers will be needed to resolve the deep relationships within the subfamily Rhacophorinae. © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society, 2008, 153 , 733–749.
