Subspecies in India
Taxonomic Information
This species was formerly treated as a subspecies of Papilio nephelus Boisduval, 1836 (as Papilio nephelus chaon Westwood, 1845). It is now raised to species level based on detailed molecular systematic studies, resulting in treating the Indian populations as Papilio chaon chaon Westwood, 1845 – Khasi Yellow Helen (Joshi & Kunte 2022, and Condamine et al. 2023). See further information here.
According to these recent studies, Papilio nephelus occurs deep in SE Asian islands, not in continental Asia.
