Nudina harpago Volynkin & Huang , sp. nov.

( Figs 5, 6 View FIGURES 1–8 , 11, 12 View FIGURES 9–12 )

Type material. Holotype ( Figs 5 View FIGURES 1–8 , 11 View FIGURES 9–12 ): male, “ Nord-Vietnam , Mai-chau, 25 km S Moc-chau, 1400m, 20.50’N/104.40’E, 14.–18.XI.1994, leg. V. Sinjaev [Sinyaev], Sekundarwald [secondary forest]”, gen. slide No.: ZSM Arct. 2019-536 (prepared by Volynkin) (MWM/ ZSM).

Paratypes. VIETNAM: 1 male, the same data as in the holotype (MWM/ ZSM) ; 5 males, N Vietnam, 1400m, Mai-chau , primary forest, 40km SE Moc-chau, 20°50’N 104°50’E, 7–15.IV.1995, leg. Sinyaev & loc. coll., gen. slide No.: ZSM GoogleMaps Arct. 2020-169 (prepared by Volynkin) (MWM/ ZSM) ; 1 male, N Vietnam, 1600–1800m, Mt. Fansi-pan (West), Cha-pa, secondary forest, 22°20’N 103°40’E, 10–30.X.1994, leg. Sinyaev & loc. coll., gen. slide No.: ZSM GoogleMaps Arct. 2020-171 (prepared by Volynkin) (MWM/ ZSM) .

Diagnosis. The forewing length is 11.5–13 mm in males. The new species can be distinguished externally by its monotonous yellow hindwing, whereas N. ankistro and N. witti have brown suffusion in the subterminal and terminal areas of the hindwing. The male genital capsule of N. harpago is very similar to that of N. ankistro but differ by the longer vinculum and the somewhat narrower ventro-distal process of the valva. In the aedeagus of the new species, the lateral carinal process is nearly straight, whereas in N. ankistro it is curved distally. In the vesica of the new species, the distal diverticulum is longer than that of N. ankistro .

The female is unknown.

Distribution. The species is known from two localities in northern Vietnam (Hòa Bình and Lào Cai Provinces).

Etymology. ‘Harpago’ means ‘a hook’ in Latin. The specific epithet refers to the hook-shaped harpe.
