Abstract
The Graphium (Pazala) mandarinus group was recently defined and the status of taxa as well as the number of specieswas revised. We report here the discovery of a new species from Kon Tum plateau of the Truong Son (Annamite) Rangeof Central Vietnam, which we describe based on morphological and molecular evidence. Molecular phylogeny shows thatthe new taxon, G. (P.) wenlingae Hu, Cotton & Monastyrskii sp. nov., is sister to G. (P.) daiyuanae Hu, Zhang & Cotton,2018 plus G. (P.) confucius Hu, Duan & Cotton, 2018. Molecular dating analysis further suggests that this new speciesdiverged from its sister clade in the Pliocene (~3.5 million years ago). The new taxon constitutes the eighth and southernmostspecies of the mandarinus group.
