Year: 2025
Type: article
Abstract: A new treefrog of the genus Gracixalus, Gracixalus huapingsp. nov., is described based on the specimens collected from Huaping National Natural Reserve, Guangxi, China. Both maximum likelihood analysis and Bayesian inference found that the Huaping population formed a distinct lineage as sister to Gracixalus jinxiuensis. It was strongly supported that Gracixalus consists of four distinct clades. Morphological analysis suggested that the new species can be distinguished from other known congeners by a combination of the following morphological characters: size small, SVL 26.6–28.8 mm in males and 29.8–32.8 mm in females; vomerine teeth absent; dorsal surface yellowish brown; internal vocal sac and linea masculina present in males; vocal sac opening oval and rim of the opening dark brown; throat smooth; iris golden brown; flanks granular with white blotch. In addition, we agree that the genus Orixalus is a junior subjective synonym of Gracixalus and consider that more studies are needed to investigate the species diversity and taxonomy of genus Gracixalus.
