Description. Male ( Figs 377–380, 383 View FIGURES 372–383 ). Forewing length 4.0– 4.5 mm; wingspan 8.6–9.6 mm (n = 7). Head: palpi and frons cream to ochreous cream; frontal tuft yellowish cream with some brown-tipped scales; collar yellow-ochre; antenna slightly or distinctly longer than one half the length of forewing; flagellum yellowish cream indistinctly annulated with pale grey scales; 3 rd enlarged segment ochreous cream. Tegula ochreous cream, densely irrorated with dark brown scales; thorax ochreous cream; sensila relatively short, almost indistinctive. Forewing densely irrorated with ochre, ochre-brown, and blackish brown scales, and with two short, oblique but indistinctive antemedian and subbasal stripes; fringe pale yellow ochre apically, pale ochreous grey on tornus; fringe line comprised of small brown-black scales; forewing underside pale greyish brown, without spots or androconia, except for dark grey-brown special scales along costal margin at the forewing base. Hindwing greyish cream to pale grey on upper side and underside, without androconia; fringe greyish pale ochre. Legs yellow cream, irrorated with pale grey-brown scales on upper side. Abdomen glossy pale ochreous grey on upper side, pale ochreous yellow densely irrorated with grey-brown scales on underside; genital plates large, pale ochreous yellow to yellowish cream; anal tufts long, yellowish cream.

Female ( Figs 381, 382 View FIGURES 372–383 ). Similar to male. Forewing length 3.8–4.4 mm; wingspan 8.2–9.5 mm (n = 5).

Male genitalia ( Figs 397–402 View FIGURES 397–402 ) with capsule 530–550 µm long, 345 µm wide. Uncus comprised of two relatively short, elongated lateral lobes and two very short, rounded median lobes ( Fig. 399 View FIGURES 397–402 ). Socii medium small, weakly paired, membranous. Valva 350–390 µm long, simply-shaped, without a dorsal lobe but with strong chetae in apical half. Anellus mostly membranous, strongly thickened laterally. Vinculum small, widely rounded distally. Phallus 370–385 µm long, apically bifid, with two pairs of very slender, long and pointed apical spines.

Female genitalia ( Figs 403–410 View FIGURES 403–410 ) ca. 1900 µm long. Ovipositor lobes large, rounded, densely covered with medium-chitinized peg-like setae; second pair of ovipositor lobes twice smaller, with numerous long setae. Anterior and posterior apophyses almost equal in length; prela comprised of three pairs of slender rod-like projections; inner prela very long, transverse prela unusually short; caudal plate comprised of a single element. Corpus bursae with a very long and extremely slender proximal part possessing some spines ( Fig. 404 View FIGURES 403–410 ), and small oval-shaped main body without distinctive pectination. Ductus spermathecae relatively short, sinuous, with 6–7 very large coils and an indistinctive vesicle.

Bionomics. Host plant is unknown (an unidentified species of Asteraceae ). Larvae mine leaves in February. The leaf mine is blotch-like, irregularly shaped, without frass. Adults occur in March. Otherwise, biology is unknown.

Distribution. This species is known from a single locality in Guatemala, Sololá Department, Panajachel, at elevation of 1660 m.

Etymology. N. subantigua is named after N. antigua Diškus & Remeikis , sp. nov., a similar, and probably closely related species.
