Abstract:
In recent years, taxonomic research of the genus Diploderma has made great progress, but there are still areas lacking relevant investigations. During 2020–2021, we carried out survey of reptile diversity in and around the Shaluli Mountains and collected some specimens of Diploderma. Of which, based on systematics inferred from mitochondrial ND2 gene sequence and morphological data, three new species were recognized: Diploderma daochengense sp. nov. from the Shuiluo River and Muli River valleys in southeastern Daocheng County, D. xinlongense sp. nov. from the upper-middle valleys of the Yalong River in Xinlong County, and D. kangdingense sp. nov. from the Yalong River middle valley and Liqiu River valley. Specifically, these three new species formed three monophyletic lineages with strongly supported and nested into the subclade I of the Bayesian and Maximum Likelihood trees. The uncorrected mean genetic distance between these new species and their closely related species was 4.3% (D. xinlongense sp. nov. vs. D. panchi), 3.4% (D. daochengensesp. nov. vs. D. yulongense) and 5.5% (D. kangdingense sp. nov. vs. D. bowoense), higher than many pairs of species of Diploderma. With respect to the morphology, D. daochengense sp. nov. can be easily diagnosed from D. yulongense by having smooth upper edge of the dorsolateral stripes, cyan or dark olive green to yellow gular spots in both sexes and light yellow or white ventrolateral body in males; D. xinlongense sp. nov. can be easily diagnosed from D. panchi by having cyan gular spot in both sexes; D. kangdingense sp. nov. can be easily diagnosed from D. bowoense by having more T4S 20–25 (average 23), more F4S 16–20 (average 17) and yellow to light yellow ventrolateral body, yellow gular spot present in males. To date, the number of species of the genus Diploderma has increased to 40, of which 37 species have been known in China.
