DESCRIPTION. Length of fore wing 15.5 mm. Antenna relatively short, about 1/3 of fore wing in length, bipectinate (crest processes short in medium third of antenna, about 1.3 of antenna rod diameter). Thorax and tegulae covered with grey scales. Fore wing grey with poorly expressed lightbrown pattern (oblique stroke at root, spot in discal cell apically, poorly expressed strokes postdiscally and submarginally). Hind wing white with thin grey undulated lines and strokes postdiscally and submarginally.

Male genitalia. Uncus large, long, split into two halves up to base; gnathos arms completely absent; valve semicircular basally with two apical processes: the first short, apically semicircular, the second long, strongly curved on border of basal and medium thirds, distal third sickle-curved, with sharp apex, from which a leaf-like membranous part outcomes; semicircular, basally wide harpe in medium third of basal part of the valve; juxta tiny; phallus ¼ shorter than valve, slightly curved in medium third, two short wedge processes on distal end, vesica aperture in dorso-apical position, vesica without cornuti, coecum membranous, bag-like.

Female unknown.

DIAGNOSIS. The new species differs from the other representatives of the genus in the following characters:

– from U. vicunensis (Ureta, 1957) — in the longer fore wing, lighter pattern and very small process on the valve;

– from U. tucumana Yakovlev, Naydenov et Penco, 2019 — in the poorly expressed reticulated pattern on the fore wing, longer apical process on the valve, longer saccus, longer and more curved phallus;

– from U. infans (Dyar et Schaus, 1937) — in the absence of the postdiscal dark area on the fore wing (cubitally), less curves arms of the uncus, longer and more curved phallus, and the short apical process on the valve;

– from all the known representatives of the genus the new species differs in the apical process of the valve, strongly curved on the border of basal and medium thirds.

ETYMOLOGY. The new species is named after Silvia Strelkov (Palma Sola, Argentina) — the director of private nature reserve Eco Portal De Piedra National Park.
