MATERIAL. Argentina: holotype, male, NW Argentina, Jujuy Prov., 10 km SEE Caimancito, 23°44´38.6´´S 064°31´09.2´´W, H= 405m, 25– 26.10.2019, leg. R. V. Yakovlev (ZISP, Genital preparation № 234, A. E. Naydenov); paratype, male, same data (RYB, Genital preparation № 271, A. E. Naydenov).

DESCRIPTION. Length of forewing 14—15 mm. Light-brown portion at root area of fore wing, discally semicircular brown spot framed in ribbon-like light-coffee color band, postdiscally wedge-shaped brown portion, submarginally extensive round brown portion, submarginally crescent brown stroke and light-brown portion at apex. Fringe brown. Hind wing light-brown coffee color, without pattern.

Male genitalia. Uncus spindle-like, long, smoothly narrowing from base to apex; gnathos arms very short; gnathos absent; valve directed ventrally, long, basally swollen, distally slightly extending, with very expressed notch on saccular edge, basally with small spiky harpe on inner surface; on border of 3/4 of valve length at distal end of outer edge — a long cylindrical process directed laterally; juxta with long process directed abdominally, with two long leaf-like lateral processes; saccus short, clavately extended apically; phallus shorter than valve, slightly curved throughout all length, apically obliquely cut; small wedge-like process on dorsal surface of phallus, at apex, vesica without cornuti.

Female unknown.

DIAGNOSIS. The species is morphologically close to G. vogli sp.n., from which it clearly differs in the thicker and shorter saccus (in G. vogli sp.n., the saccus is very long and thin) and in the robust long process on the outer edge of the valve (in G. vogli sp.n. the process is thin, apically acute).

DISTRIBUTION. NW Argentina, Jujuy Province.

ETYMOLOGY. The species is named after Alex-Vadim Strelkov — the remarkable owner of our camp, who provided all the conditions (including excellent craft beer) for collecting material, which altogether helped in our work, despite the abundance of caimans and very hot weather.
