Two New Species of Acanthosaura Gray, 1831 (Reptilia: Agamidae) from Yunnan Province, China

Abstract

Two new species of the genus Acanthosaura Gray, 1831, previously identified as A. lepidogaster (Cuvier, 1829), are described from Yunnan Province, China, based on morphological and genetic data. The first new species from Jiangcheng County, southern Yunnan, is characterized by having very long tail in males and the second new species from most parts of southwestern Yunnan is characterized by having obvious bright red lips in males and fewer nuchal crest scales. Genetically, uncorrected sequence divergences of COI between the two new species and investigated congeners ranged from 5.5 to 21.6%.
