68a. Papilio maackii han Yoshino, 1997

Achillides maackii han Yoshino, 1997; Neo Lepidoptera, 2 (2): 2, pl. 1, f. 5–10, 54; TL: ‘Mt. Wuyishan, Fujiang prov., China’ [Wuyi Shan, Fujian, E. China].

Papilio maackii shimogorii Fujioka, 1997; in Fujioka et al., Jap. Butts Relativ. World, 1: 293; TL: ‘Mt. Omeishan, Sichuan, China’.

Distribution: only found in the lowlands of N.E. Yunnan; but widely distributed in C. to E. China.

Note: the species identities of P. syfanius and P. maackii had previously been disputed, until a recent genomic study confirmed they are two distinct species with a natural genetic exchange zone (Xiong et al. 2022). Condamine et al. (2023) confirmed this finding under a broader sampling background including over 80% of the world’s Papilio species.
