33. Graphium septentrionicolus Page & Treadaway, 2013

Graphium adonarensis septentrionicolus Page & Treadaway, 2013; Stutt. Beitr. Naturk. A (NS), 6: 239, f. 19–20; TL: ‘Nowgang, Assam, India’.

Distribution: confined to the lowlands and river valleys in W., N.W., to S. Yunnan; also found in S. Tibet, as well as N.E. India, N. Myanmar and N. Indochina.

Note: Although extremely similar to G. sarpedon (Linnaeus, 1758), a recent DNA and morphology-based study (Cotton et al. 2022) confirmed its distinct species identity. The most reliable distinguishing characters are male genitalia and hindwing scent scales.
