The radiation of microhylid frogs (Amphibia: Anura) on New Guinea: a mitochondrial phylogeny reveals parallel evolution of morphological and life history traits and disproves the current morphology-based classification.

摘要: Microhylidae account for the majority of frog species on New Guinea and have evolved an extraordinarily wide range ecological, behavioural, morphological traits. Several are known their unique paternal care behaviour, which includes guarding clutches in some additional froglet transport other species. We sampled 48 out 215 Guinean microhylid all but two (Mantophryne Pherohapsis) 18 genera analysed a concatenated data set partial sequences mitochondrial genes 12S 16S, comprises 1220 aligned nucleotide positions, order to infer phylogenetic relationships within this diverse group frogs. The trees do provide resolution at shallow, not deep branches. Monophyly is rejected Callulops, Liophryne, Austrochaperina, Copiula, Cophixalus as currently recognized. Six clades well supported: (1) Hylophorbus Callulops cf. robustus, (2) its sister taxon comprising Xenorhina, Asterophrys turpicola, except C. (3) Liophryne rhododactyla, L. dentata, Oxydactyla crassa, Sphenophryne cornuta, (4) Copiula (5) Barygenys exsul, spp., Oreophryne, (6) sphagnicola, Albericus laurini, Choerophryne. phylogenies evidence parallel evolution parental modes, life styles, traits that thus far been emphasized recent classifications.
