Diagnosis. Externally similar to N. bistrigata , from which it differs by larger size, straight oblique stripe in the apical part of forewing (bent in N. bistrigata ) and normally sized male genitalia (total length 1.10 mm vs. 0.48 mm in N. bistrigata ) with long vinculum (2 × its width vs. 1 × its width in N. bistrigata ).

Etymology. Named after William Doherty (1857–1901), an American entomologist and enthusiastic moth collector, who collected the type specimens.

Description. Male ( Figs. 4 , 13 ). FWL 6.3–6.9 mm; WLR 0.34–0.36. Vertex with sparse row of brown piliform scales along the occipital margin; frons brownish grey. Eyes enlarged, touching each other occipitally; interocular index 1.2. PLB 0.6 × vertical eye diameter and 1.3–1.5 × scape, dark brown. Proboscis dark brown. Antenna 3.1–3.2 × FWL. Scape and 6–8 basal segments of flagellum dark brown; following segments (up to 0.3 of flagellum) brown, with distinct white rings; distal part of flagellum entirely light grey to white. Tegula and thorax dark brown. Forewing light brown; its basal part (ca. 0.7 × FWL) densely suffused with dark brown scales and sparsely scattered with yellow scales (approximately in 15:1 ratio). Oblique stripe in the apical part of forewing straight, ochreous, reaching (or almost reaching) external wing margin. Wing apex between the veins RS1 and M1 with small ochreous stripe bordered by dark brown scales both internally and externally; the area between these two ochreous stripes dark silver grey. Fringe brown. Hindwing brown; costal area light grey; fringe brown. Legs brown; apices of tibiae and of all tarsomeres white; fore and hind tibiae medially with white spots; base of the first tarsomere white. Epiphysis at 0.5, not reaching tip of tibia. Abdomen brown.

Female unknown.

Male genitalia ( Figs. 28–32 , 40, 41 ). Tegumen wide, with W-shaped apex. Socius elongate, 1.0–1.2 × diameter of phallus. Vinculum 1.6 × length of valva, with slightly concave lateral margins, narrowly rounded basally; distal margin of vinculum indistinct, fused to valvae. Apex of valva extends far beyond the apex of tegumen. Valvae fused basally up to 0.35 × total length; their internal margins indistinct; dorsal margin of valva almost straight; distal part of valva narrow; apex of valva pointed. Anellus 0.3 × length of valva. Transtilla with small triangular medial process. Juxta 0.45 × length of phallus; arrow head very narrow (WLR 0.2), without lateral arms; apex of juxta rounded. Phallus 1.0 × length of vinculum, straight; base of phallus narrowly funnel-shaped.

Distribution ( Fig. 9 ). Indonesia (Irian Jaya).

Comments. The type locality (Fakfak) was identified using the map in the notebook by Walsingham (accessed in NHM).
