Abstract
The present study evaluates the taxonomic status of “Rhacophorus namdaphaensis” sensu stricto using morphology, molecular and acoustic tools. Our phylogenetic analyses based on the mitochondrial 16S rRNA gene, morphological examination of type collections, and freshly collected topotypes, along with bioacoustics information, suggest that “Rhacophorus namdaphaensis” sensu stricto is a valid species. We provide the redescription for the species, describe the tadpole morphology and discuss the extended geographical distribution.
