Other material. Australia, Queensland. 2 ♂ 3 ♀, Kuranda, 12.vii. –8.x.1904 (Dodd); 1 ♀, Huberton Hills, Evelya Scrub, x.1910 (Dodd) (all in NHM).

Diagnosis. N. panaeola is nearest to N. turneri , from which differs by dark brown head, longer PLB (0.45– 0.55 × vertical eye diameter) and coppery brown dorsum in males, as well as by yellow spot at the base of forewing usually reaching dorsal wing margin. In male genitalia N. panaeola differs from N. turneri by semicircular shape of the basal half of valva (in lateral view) and dome-shaped tegumen.

Description. Male ( Figs. 5 , 16). FWL 4.8–5.6 mm, WLR 0.33–0.36. Vertex with mixture of black and dark brown piliform scales and with a few yellow scales above antennal sockets; frons glossy golden. PLB 0.45–0.55 × vertical eye diameter, pale yellow to light ochreous brown, with sparse raised brown piliform scales. Proboscis light brown, base with tuft of elongated bronze to ochreous brown scales. Eyes enlarged; interocular index 1.2–1.3; occipital index 0.10. Length of antenna 2.7–2.8 × FWL. Scape and base of flagellum dark bronze; pegs absent; distal part of flagellum bronze. Tegulae dark bronze to coppery bronze; thorax dark brown with coppery tint. Forewing coppery bronze; basal field dark brown, reaching costa at 0.28 × FWL and dorsum at 0.22 × FWL; dark brown line at the external margin of basal field is absent in some specimens. Glossy golden spot along costa relatively short (0.2 × FWL), distally adjacent to small pale yellow spot; pale yellow spot at the base of dorsal wing margin variable in shape, but in all investigated specimens reaches dorsal wing margin. Fascia is formed by a mixture (approximately 1: 1) of dark brown and yellow scales, which in some specimens are arranged in narrow alternating lines (one scale in width); internal margin of fascia sinuate, reaching costa at 0.50–0.55 × FWL, i.e. far from the apex of basal glossy golden spot. External margin of fascia nearly straight, consists almost exclusively from dark brown scales, with distinct dark brown spot near costa. Tornal spot variable in size. Fringe coppery bronze to bronze. Hindwing coppery brown, base only slightly lighter than apex; costal area brownish grey; fringe light brown to grey. Legs bronze to brown, apices of all tibiae and tarsomeres distally darker, sometimes with coppery tint. Epiphysis at 0.45–0.55, not reaching apex of tibia. Abdomen brown with bronze lustre; basal sternites glossy golden.

Female ( Fig. 6 ). FWL 4.5–5.1 mm. Antenna 1.4–1.5 × FWL, base not thickened. Vertex pale yellow to ochreous yellow. Otherwise similar to male.

Male genitalia ( Figs. 31–35 ). Tegumen dome-shaped, wide, indented medially. Socius oval, 1.0 × diameter of phallus. Vinculum 3.0 × length of valva, with slightly concave lateral margins and W-shaped distal margin. Apex of valva extends beyond the apex of tegumen. Ventral margin of valva convex, with prominent medial lobe at 0.55 × length of valva; dorsal margin slightly concave; apex of valva pointed. Valvae fused basally up to 0.05 × total length; internal margins of valvae indistinct. Anellus 0.25 × length of valva. Transtilla with wide triangular medial process. Juxta 0.5 × length of phallus; arrow head narrow (WLR 0.45), with pointed tip and pointed lateral arms. Phallus 1.0 × length of vinculum, almost straight; apical part hook-shaped; base of phallus narrowly funnel-shaped.

Comments. Investigation of two syntypes of N. panaeola revealed that they belong to different species. The lectotype was selected to fit the original description; the paralectotype belongs to N. turneri sp. nov.
