Head, thorax and tegulae with pale-yellow scales. Collar at head light-brown. Labial palpi short, straight, almost twice smaller than longitudinal eye diameter. Antennae thin, light-yellow, alternating with small brownish scales, scape noticeably extended. Wingspan 18-21 mm (in holotype 19 mm ). Fore wings yellowish-grey. Small elongated dark-brown spot along costal margin, above cleft. Brownish spot in front of cleft. Brown fringe inside cleft and along rear margin of wing. Hind wings unicolorous, of the same color as fore wings. Hind legs yellowish-grey. Figure 7. Hellinsia katja Ustjuzhanin & Kovtunovich sp.nov. Biotope: Argentina, Andes Mts., Siera de Famatina, 2085 m, Photo by A. Pototski. Male genitalia. Valves asymmetric. Saccular process on left valve sclerotized, arched at right angle, distally narrowing, apically acute. Saccular process on right valve shaped as wide fold, located in medium part. Apices of both valves bluntly rounded. Uncus simple, thin, slightly curved. Anellus arms asymmetric, left shorter and more narrow than right. Vinculum arched. Aedeagus thin, slightly curved, twice shorter than valve. Figure 8. Emmelina inna Ustjuzhanin & Kovtunovich sp.nov. Adult male (Holotype, IZBE). Figure 9. Emmelina inna Ustjuzhanin & Kovtunovich sp.nov. Male genitalia (Holotype, IZBE, gen.pr. Nr. 221003). Female genitalia. Papillae anales wide. Posterior apophyses almost straight, three times longer than anterior apophyses. Anterior apophyses short, thick, slightly narrowing apically. Antrum short, tubulate. Ductus bursae long, thin, membranous. Ductus seminalis slightly wider and shorter than ductus bursae. Bursa copulatrix long, narrow-oval, poorly sclerotized, without signa. Diagnosis. Externally, the new species remotely resembles Emmelina monodactyla (Linnaeus, 1758) . In the male genitalia, in the curved saccular process on the left valve, the new species resembles Emmelina aethes (Walsingham, 1915) , but in E. aethes this process is hook-like, while in the new species it is arched. The left valve in the new species is apically rounded, while in E. a ethes it has a robust crest-like process on apex. There is also difference in the anellus arms and aedeagus. Flight period. September. Distribution. Argentina . Etymology. The new species is named after Risto Haverinen's daughter Inna Antikainen, who has been a source of innovation and a driving force during expeditions.
