Graphium (Pazala) garhwalica ( Katayama, 1988) stat. nov.

( Figure 9 , A–B)

Pazala glycerion garhwalica Katayama, 1988 ; Gekkan-Mushi, 203: 8; pl. 1, f. 1–2; TL: “Joshimath (2400 m), Uttar Pradesh [= Uttaranchal ], NW. India ”.

Diagnostic characters: Small in size, forewing length: male 32.5–33.5 mm (n = 2), female 32.0 mm (only one female examined) [ Katayama (1988) stated 36 mm for the female in the original description]. Both wings rather whitish. Forewing, glossy, apex blunt, termen straight (a); veins M3 to Cu2 discally completely free of black scales in both sexes (b). Hindwing, black discal band on the upperside completely reduced in both sexes (c), short submarginal black lines also reduced on the upperside in both sexes, only reaching space sc+r1.

Distribution: N.W. India (Uttaranchal Pradesh) to C. Nepal (Annapurna).

Phenology: Univoltine in April-May.

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

Male genitalia ( Figure 10 ): In total two male genitalia were dissected, the general characters are consistent. Highly sclerotised. Ring slightly wavy in the upper half; saccus very small, nearly reduced; distance between the base of socii 0.64–0.68 mm (n = 2). Valve short, oval in general, the end of dorsal terminal harpe extends into distinctly elongate acute tip; the dorsal subterminal harpe reaching the base of the elongate tip; the medial harpe long and curved, the dorsal projection flat and serrate; no tooth in the middle of the medial harpe. Juxta weakly sclerotised with hairy membrane on both sides.

Female genitalia: The abdomen of the only available female specimen was unfortunately crushed prior to obtaining the specimen, the ostial lobe was still identifiable but split into three pieces. The first author photographed the three pieces and digitally rejoined them without alteration, obtaining a reconstructed image of the ostial lobe ( Figure 11 ). Ostial lobe ( Figure 11 ) heavily sclerotised, broad at the base with the posterior margin widely bifurcated into a pair of broad spurs in ventral view.
