中国一新纪录种滇西鱼螈

A new species record of <italic>Ichthyophis moustakius</italic> is documented from southern Gaoligong Mountain, Yunnan Province, China, based on integrative taxonomic evidence from morphological and molecular analyses. Phylogenetic reconstruction using mitochondrial DNA placed the newly collected Chinese specimens within a strongly supported clade comprising recognized <italic>I. moustakius</italic> specimens from India. Uncorrected pairwise distances of 16S rRNA gene sequences between Chinese and Indian specimens ranged from 1.2% to 2.6%, indicating minimal genetic divergence. Morphological assessments revealed concordance between the Yingjiang specimens and those from the type locality in Manipur, India. Furthermore, cytochrome b (cyt <italic>b</italic>) gene analysis excluded the possibility of misidentification with <italic>Ichthyophis kohtaoensis</italic>. These findings extend the known distribution of <italic>Ichthyophis</italic> in China, raising the number of recognized species to three, and offer detailed morphological characterizations of both adult and larval stages.
