Abstract
The Plateau Pit Viper, Gloydius strauchi, from southwest and central China has long been considered a single, widespread species despite suspicion that it represents a potential complex of distinct evolutionary lineages. Although series of works were published on the G. strauchi species complex over the last 10 yr, species boundaries and diagnostic features of different members of the complex have remained poorly understood. Combining both morphological and genetic data, we re-evaluate taxonomic statuses of populations of G. strauchi in southwest China and describe the eastern Tibetan populations as a new species. The new species is most closely related to G. monticola phylogenetically, and it differs from all congeners by having a matte dorsal body scale texture, oval and robust head shape, distinct body ornamentation and coloration, and unique hemipene morphology. In addition, we provide the first updated diagnostic key to all recognized members of the G. strauchi species complex, and discuss ongoing taxonomic problems associated with cryptic diversity within the genus in China.

Etymology.— The specific name is derived from the surname of Chinese herpetologist Dr. Song Huang from Huangshan University, who has made continuous contributions to research on Chinese snakes in Tibet and the HMR. We suggest ... (Pinyin: Lan Cang Fu) as the Chinese common name of the new species, and Lancang Plateau Viper as its English common name, in the hope of promoting habitat conservation of the Lancang River Basin where the species is native.
