Distribution: commonly found in low altitude tropical areas in W. to S.E. Yunnan; also found in S. China, as well as Nepal to Myanmar and Indochina.

Note: Condamine et al. (2023) confirmed the identity of Papilio chaon as a separate species from P. nephelus , found in the Malay Peninsular, Sumatra, Borneo and Java. Thus, the species in Yunnan is correctly P. chaon , with the nominotypical subspecies and ssp. rileyi present in the province.
