Gracixalus carinensis was originally described from Myanmar, but samples of the species reported in molecular phylogenetic works were all from Vietnam, far apart from the type locality. Moreover, the voucher specimens used for sequencing seem to have never been critically studied. We newly sequenced specimens from Vietnam and also closely examined morphology of vouchers. As a result, we confirmed that samples treated under this name from Vietnam constitute a single species. Although no molecular data are available for topotypic samples from Myanmar, detailed morphological comparisons revealed that samples from Vietnam are constantly separated from the topotypic samples of G. carinensis by much poorly developed toe webbing. We thus consider the Vietnamese samples as an undescribed species and describe them as G. sapaensis sp. nov.
