Singularia zolotuhini Kovtunovich et Ustjuzhanin , sp.n.

Figs 1–3 . TYPE MATERIAL: Holotype ♂, ( ZISP, gen.pr. Nr. 1960), COLOMBIA: Quindío Valle del Cocora E of Salento, 2360 m 4°38´41´´N / 75°29´15´´W, 14.iii.2017, V. Sinyaev leg. Paratype : 1

female ( ZISP, gen.pr. Nr.1961) COLOMBIA: Antioquia SW of Dabeiba , 780 m 6°59´27´´N / 76°16´28´´W, 17–18.iii.2017, V. Sinyaev leg.

DESCRIPTION. External characters.Length of fore wings 19–20 mm (holotype — 19 mm). Head and thorax covered with dark-grey hairs. Labial palpi straight, twice longer than longitudinal eye diameter. Wings dark-grey. First lobe of fore wing distally brightly white, second lobe less bright, with portion of dark fringe apically. Hind wings and fringe unicolorous ash-grey. Legs light-brown with bright white spurs.

Male genitalia. Uncus wide, beak-likely sharpened, with clearly expressed narrow dorsal process. Valves asymmetric. Left valve wide, oval, apically narrowing. Right valve narrow, distally bent at a right angle, noticeably narrowing. Anellus arms asymmetric, right arm very wide, left arm narrow, thin. Saccus wide, arched. Aedeagus thin, S-shaped.

Female genitalia. Papillae anales oval, wide. Posterior apophyses long, straight, apices slightly acute. Ductus long, wavy. Bursa copulatrix with longitudinal ribbon-like signum, passing almost through all length of bursa.

DIAGNOSIS. In the male genitalia, in the expressed dorsal process on the uncus, the new species is similar only to Singularia leptochorda (Meyrick, 1913) , but in the new species the process is narrow, while in S. leptochorda it is wide. Additionally, the wide left valve and the S-shaped aedeagus differentiate the new species. In the female genitalia, in the ribbon-like longitudinal signum, the species is also similar to S. leptochorda , but differs in the long wavy ductus.

FLIGHT PERIOD. March.

DISTRIBUTION. Colombia.
