( Figs 3, 4 View FIGURES 1–8 , 9, 10 View FIGURES 9–12 , 19 View FIGURES 17–19 )

Type material. Holotype ( Figs 3 View FIGURES 1–8 , 9 View FIGURES 9–12 ): male, “ Myanmar (Burma), 25 km E Putao, env. Nan Sa Bon vill., 800m, 6– 9.V.1998, leg. Murzin & Sinjaev [Sinyaev]”, gen. slide No.: ZSM Arct. 2020-166 (prepared by Volynkin) (MWM/ ZSM).

Paratypes. MYANMAR: 1 male, Myanmar (Burma), 50 km E Putao, env. Nan Thi village , 950m, 11– 16. V.1998, leg. Murzin & Sinyaev, gen. slide No.: MWM 33518 (prepared by Volynkin) (MWM/ ZSM); GoogleMaps 1 male, Kachin State, Malaria village , 27.5701°N, 97.3716°E, alt. 470 m, border between mountain rainforest and grass pastures, 14.III.2014, Bolotov & Spitsyn leg., RMBH unique number: Sph 0891, gen. prep. in glycerol by Spitsyn ( RMBH) GoogleMaps .

Additional material examined: 2 females, Myanmar (Burma), 50 km E Putao, env. Nan Thi village , 950m, 11– 16. V.1998, leg. Murzin & Sinyaev, gen. slide Nos. : ZSM Arct. 2020-167, ZSM Arct. 2020-199 (females) (prepared by Volynkin ) (MWM/ ZSM) .

Remark. We associate the two females from the vicinities of Nan Thi Village with N. ankistro as only the species was collected in the locality. However, as N. ankistro occurs sympatrically with N. witti in another locality in northern Myanmar, the specific belonging of the females remains doubtful. Unfortunately, the female specimens are old and unsuitable for comparison with males using molecular methods. For these reasons, we do not include the females to the type series.

Diagnosis. The forewing length is 11–11.5 mm in males and 10.5–11.5 mm in females. The new species differs externally from its relatives by the dark brown antennae (those are yellow in N. harpago and N. witti ), the narrower male forewing and the intense dark brown suffusion in the subterminal and terminal areas of the hindwing of both sexes. The male genitalia of N. ankistro are very similar to those of N. harpago , the comparison is provided below in the diagnosis of the latter species. As the females of N. harpago and N. witti are unknown the female genital morphology of N. ankistro is compared to that of N. artaxidia : in the new species, the postvaginal plate is narrower, the antevaginal plate is narrower and rounded (it is wider and has a straight posterior margin in N. artaxidia ), the ductus bursae bears an elongate sclerotized plate ventrally (it bears a small plate and two clusters of spines in N. artaxidia ), the corpus bursae is more heavily scobinated, and the appendix bursae is longer, has broader basal section, its distal section is weakly granulated, curved and apically tapered, directed anteriorly (whereas in N. artaxidia it is conical, membranous and directed laterally).

Distribution. The species is known from two localities in northern Myanmar (Kachin State).

Etymology. ‘Ankistro’ is the Latin transliteration of the Greek word ‘άγκιστρο’ meaning ‘a hook’. The specific epithet refers to the hook-shaped harpe.
