First record of Calotesvindumbarbatus Wagner, Ihlow, Hartmann, Flecks, Schmitz & Böhme, 2021 (Squamata: Agamidae) from China, with revised diagnosis of this species.

BACKGROUND: Three new species were recently described from the Calotesmystaceus Duméril & Bibron, 1837 complex. Of the three new species, C.vindumbarbatus Wagner, Ihlow, Hartmann, Flecks, Schmitz & Böhme, 2021 was known only from northern Myanmar. NEW INFORMATION: Seven specimens of lizard were collected from Tongbiguan Nature Reserve, western Yunnan, China. Phylogenetically, these specimens clustered with the type specimens of Calotesvindumbarbatus from Myanmar with strong support and showed inappreciable genetic divergence from the type specimens of C.vindumbarbatus. We report the first country record of C.vindumbarbatus from China. In addition, a supplementary description, based on the newly-collected specimens and revised diagnosis of this species, was provided.
