Molecular phylogeny reveals cryptic diversity in from China (Serpentes: Sibynophiidae).

The elucidation of species diversity and distribution is critical within the fields of evolution, genetics, and conservation. The genus contains rare snakes that have historically received little attention. In this study, we conducted comprehensive sampling and use both mitochondrial and nuclear genetic markers to explore species diversity within China. Our findings revealed that should be considered synonymous with , and should be gave a specific rank as . In addition, we discovered was new to China and Myanmar. Based on the specimens and molecular phylogeny results, we redefined the species distribution boundaries of each Chinese species.
