Graphium (Pazala) mandarinus fangana ( K. Okano, 1986)

( Figure 25 , D and E)

Pazala glycerion fangana K. Okano, 1986 ; Tokurana, 11 (3): 1, f. 3; TL: “near Fang, alt. 2,200 m, (about 20°20′ N, 99°50′ E), Chieng Mai Prov., North Thailand ” [The co-ordinates stated in the original description are inaccurate, the correct coordinates are approximately 20°05′ N, 99°08′ E].

Diagnostic characters: Very similar to the preceding subspecies in appearance, forewing length: male 26.0–31.0 mm (mean = 29.2 ± 1.2 mm, n = 29), female 32.0 mm (only one female). Forewing, apex slightly blunt, also not produced, termen straight; vein M3 and the base of vein Cu1 tinged with black scales in both sexes. Hindwing, submarginal black short lines better developed than the preceding subspecies, which may reach space sc+r 1 in some specimens.

Distribution: Only known from a few mountains in northern Thailand near Mae Ai and Fang districts. The restricted range of this taxon effectively inside the potential range of the previous subspecies needs further study. It is notable that ssp. kimurai is absent from the mountains where fangana occurs, and the taxa are genetically distinct as well as separable on wing pattern.

Phenology: This subspecies is univoltine, flying only in February and March, unlike ssp. kimurai . Recently deceased Prasobsuk Sukkit (pers. comm.) confirmed that he and local collectors have looked for ssp. fangana throughout the year over many years, and never found it other than in February to March.

Host plant: Unknown, presumably a plant species belonging to family Lauraceae .
