TL: Mandalay [ Myanmar]; TD: CAS

Material Examined: 2 ♂♂, Arunachal Pradesh, Dibang Valley dist., Dihang-Dibang BR, Eduli , 147 m, 27.9519°N; 95.8133°E, 07. i. 2017, leg. A.K. Sanyal & Team.

Distribution: India: Arunachal Pradesh. Elsewhere: Myanmar, Thailand, China (Yunnan).

Diagnosis: Forewing length ♂♂ 25 mm.

Both male and female adults of this species resemble much to P. postruba (Swinhoe, 1903) , but external appearance of the latter is darker and more reddish tinged. P. orest Schintlmeister, 1997 , a further closely related and similar species, have wing coloration paler than genitale , in particular hindwings are white rather than light brown. P. genitale can be best identified by male genitalia characters which possess a distinct wide gap between the lobes of uncus; broad sacculus, a tooth-like projection at the basal area of costal process of valvae; bifurcate juxta process with asymmetrical short arms; phallus with slender and prominently curved tip.
