A new species of the genus Acanthosaura Gray, 1831 (Reptilia, Lacertilia, Agamidae) from the China-Myanmar border region in southwestern Yunnan Province, China

Using an integrative dataset of both mitochondrial DNA and morphological data, we describe a new species of the genus Acanthosaura from the China-Myanmar border region in Menglian County, Pu’er, Yunnan Province, China. The new species, Acanthosaura aurantiogularis sp. nov ., is sister to A. tongbiguanensis , and it can be readily diagnosed from all recognized congeners by its bright orange gular coloration in the male, flesh colored oral cavity, moderate post-orbital spines and occipital spines, five or six well-developed nuchal crest scales, and a distinct dorsal coloration. We recommend further comprehensive phylogenetic studies of the genus and highlighted the understudied agamid diversity in northeastern Myanmar.
