A new species of Tupaia (Mammalia, Scandentia, Tupaiidae) from northeastern Vietnam
crossref(2022)
摘要
There are 19 currently recognized species of treeshrews in the genus Tupaia (Tupaiidae, Scandentia) with a majority of the taxa found in Southeast Asia. During our surveys in northeastern Vietnam, nine new specimens of Tupaia were collected from five different localities, including Lang Son and Ha Giang provinces and Cat Ba Island, Hai Phong City. Our molecular analysis reveals that the new population diverges from its closest congeners by at least 11.2% based on a fragment of the mitochondrial COI gene and 10.1% based on a fragment of the mitochondrial cytochrome b (Cyt b) gene. The distinction of the newly discovered population is also supported by significant differences compared to other species based on morphological analysis. As a result, a new species, Tupaia danghuyhuynhi sp. nov., was described based on morphological and molecular evidence.
