Abstract
The previously recognised closely related species Graphium (Pazala) mandarinus (Oberthür, 1879) and G. (P.) sichuanica(Koiwaya, 1993) are shown to comprise seven species as a result of both molecular and morphological analysis. Molecular dating analysis is also performed on the mandarinus group in order to investigate the divergence time of the taxa. Two HU ET AL. 402·Zootaxa 4441 (3) © 2018Magnolia Presstaxa, G. (P.) garhwalica (Katayama, 1988) stat. nov. and G. (P.) paphus (de Nicéville, 1886) stat. nov., are raised from sub-specific to specific status; G. (P.) hoeneanus Cotton & Hu nom. nov., stat. rev. is separated from sichuanica at species level; and two previously unrecognised new species, G. (P.) daiyuanae Hu, Zhang & Cotton sp. nov. and G. (P.) confucius Hu, Duan & Cotton sp. nov. are described from Vietnam and China respectively, the latter being sympatric with nominate G.(P.) mandarinus. The identity of the lectotype of G. (P.) mandarinus is confirmed and a lectotype is designated for the tax-on Papilio Glycerion Gray, 1831. A new subspecies of G. (P.) mandarinus is described from western Yunnan and northern Myanmar, G. (P.) mandarinusstilwelli Cotton & Hu ssp. nov.
