59. Papilio everesti Riley, 1927 stat. nov.

P. [apilio] machaon everesti Riley, 1927; Trans. ent. Soc. Lond., 1927 (1): 120; TL: ‘ Tibet: Rongbuk Glacier, 15– 17,000 ft. ’.

Note: Lee (1980) recognised three species in the Papilio machaon complex in China based on adult morphology (Figure 12) and genitalia of both males and females (see under Papilio machaon, Figures 13–18). As well as Papilio machaon Linnaeus, 1758, Lee separated the short tailed high elevation taxon as Papilio annae Gistel, 1857 and the very long tailed Yunnan taxon as Papilio verityi Fruhstorfer, 1907, but this classification was overlooked by previous publications. Examination of genitalia of these three taxa from Yunnan confirmed their status as separate species, and recent DNA analysis reported in a conference poster by Todisco et al. (2023) confirmed Papilio everesti as a distinct species. Papilio annae Gistel, 1857 was shown by Dierl (1977) to be a synonym of the long tailed lower altitude western Himalayan Papilio machaon asiatica Ménétriés, 1855, rather than the short tailed highaltitude taxon in the eastern Himalayas, so Lee (1980) applied the name annae incorrectly to the short tailed eastern Himalayan taxon. The oldest available name is Papilio everesti Riley, 1927, and the species comprises the following subspecies:
