4. Papilio alcmenor nausithous Oberthür, 1918

Recorded distribution: Xishuangbanna (Chen 2001: 51).

Note: The population Chen (2001) referred to this taxon in Xishuangbanna actually belongs to the nominotypical subspecies of Papilio (Menelaides) alcmenor C. Felder & R. Felder, 1865 . P. alcmenor nausithous occurs in Sichuan and Shaanxi (Wu & Hsu 2017), and is probably present in N.E. Yunnan, which requires future confirmation.
