Revisiting the Species Delimitation Within <i>Amolops mantzorum</i> (David, 1872), with a Description of a New Subspecies (Anura, Ranidae).

ABSTRACT: Accurate species delimitation benefits detailed biological descriptions and conservation practices. In this study, we focus on a frog species distributed throughout the western edge of Sichuan Basin, China, the Sichuan torrent frog-Amolops mantzorum. Currently, A. mantzorum is recognized as comprising two subspecies-the nominate subspecies A. m. mantzorum and A. m. xinduqiao. We investigated a population from along the Yalong River, Sichuan Province, China which was previously overlooked in phylogenetic studies. Combining multiple mitochondrial genes (16S, CO1, cytb), we identified four distinct lineages within A. mantzorum using Bayesian inference and maximum likelihood phylogeny.
