Although the nominate subspecies of <i>H. orientalis</i> and the other subspecies, <i>H. orientalis qianshan</i>, are known to exhibit geographic segregation, the taxonomic status and distribution pattern of these two groups remain unverified by integrated evidence and comprehensive sampling. In addition, the color-pattern polymorphism of this newt is poorly studied. Herein, based on extensive geographic sampling (128 samples, 19 localities), morphological examination, and phylogenetic analysis of mitochondrial NADH dehydrogenase subunit 2 (ND2) gene fragments, we elevate the Dabie Mountain region subspecies to distinct-species status as <i>H. qianshan</i> <b>stat. nov</b>., and reassess its distribution range. Morphologically, this newly ranked taxon distinctly differs from <i>H. orientalis orientalis</i> by its smaller body length ratios (TOL/SVL and TAL/SVL), smaller fore-limb length ratio (FLL/SVL); longer internasal distance in males, longer interorbital distance in females; rust-red or rust-white patches on the dorsum; discontinuous dorsal ridge lines; the presence of orange-red patches on finger I; discontinuous or absent black stripes on the venter; and relatively inconspicuous vertebral ridge. Molecularly, the newly ranked taxon forms an independent clade with strong support (1.00/99) in the phylogenetic trees; the uncorrected group mean genetic distance between the newly ranked taxon and <i>H. orientalis orientalis</i> was 3.5%. Geographically, the newly ranked taxon and <i>H. orientalis orientalis</i> are separated by the Yangtze River, Luoxiao Mountains, Jiuling Mountains and Mufu Mountains.
