Description. Male ( Figs 36–37 , 42–46, 48 ). Flagellum covered with white scales, rami dark brown or black. Head white. Thorax mesally has black and white speckled pattern with yellow scales. Abdomen white with brown or black stripes developed between abdominal sclerites. Forewing. Forewing length: 17–20 mm; wingspan: 36–42 mm. Elongated ellipsoid, apex rounded, outer margin smooth. Background color white or yellowish. Pattern dark brown or black with rare yellow scales, consist of: speckled antemedial band of hourglass shape, sometimes mesally discontinuous, laterally accompanied by fragmented lines; discal mark; medial field with more or less developed speckled pattern; doubled crenulated postmedial line; crenulated external line with dark speckled apical field. Fringe white with black spots. Hindwing. Somewhat triangular. Background color white or yellowish with dark discal spot, external field and spots along external margin. Genitalia ( Figs 39–40 , 60 ). Uncus beak-shaped with pointed apex, loosely covered with chaetae. Socii hardly sclerotized and grown together into hoof-shaped structure, loosely covered with chaetae. Tegumen and vinculum a fused band. Valva semioval, membranous, unevenly covered with setae of variable length, ventrally basally sclerotized, dorsally bears half-connected sclerotized fingerlike ridge with dents apically. Juxta a band fused to vinculum. Aedeagus sickle-shaped with widened phallobase. Vesica long, spiral, caudally narrowed. Eighth sternite oval, caudal margin with medial concavity. Eighth tergite somewhat oval. Female ( Figs 38 , 47, 49–50 ). Similar to male but bigger and antenna pectinations much shorter. Forewing length: 21–22 mm; wingspan: 43–46 mm. Genitalia ( Figs 41 , 66 ). Papillae anales crescent-shaped, densely covered with setae. Posterior and anterior apophyses about the same length. Sterigma hardly sclerotized, lamella antevaginalis with medial concavity, antrum small. Ductus bursae spiral, about the length of corpus bursae. Corpus bursae large, egg-shaped.

Variability. Background color of wings may be white ( Figs 42, 47 ) or yellowish ( Figs 46, 49 ); pattern may be black ( Figs 42, 47 ) or dark brown ( Figs 45, 49 ). Abdomen has brown ( Figs 45, 49 ) or black stripes ( Figs 43, 50 ). Antemedial band may be continuous ( Figs 44, 50 ) or discontinuous ( Figs 42, 49 ).

Diagnosis. Furcula aeruginosa petri ( Figs 51–53 ) is smaller than F. victoria sp. n., has shorter forewings and more or less pronounced creamy background color, while F. victoria sp. n. is white or yellowish ( Figs 42–50 ). Furcula bifida ( Figs 54–56 ) has a wide antemedial band on the forewing and may have a more or less pronounced dark external field on hindwing, which may be brown, while the antemedial band of F. victoria sp. n. often narrows medially or is discontinuous and the external field is not as pronounced ( Figs 42–50 ); the costal process of valva lacks dents ( Fig. 63 ) in F. bifida , while F. victoria sp. n. has dents ( Fig. 60 ); F. bifida has a paired semioval signum ( Fig. 68 ), while F. victoria sp. n. does not ( Fig. 66 ). Furcula danieli ( Figs 57–59 ) has creamy background color, while F. victoria is white or yellowish ( Figs 42–50 ); and the costal process of valva is without dents ( Figs 64–65 ), while F. victoria sp. n. has dents ( Fig. 60 ); the lamella antevaginalis is bigger ( Fig. 69 ) than of F. victoria sp. n. ( Fig. 66 ). Furcula terminata ( Figs 8–25 ) is overall darker than F. victoria sp. n. ( Figs 42–50 ); its lamella antevaginalis has a deeper medial concavity and larger antrum ( Figs 32–35 ) than that of F. victoria sp. n. ( Figs 41 , 66 ).

Etymology. The new species is dedicated to Ms Victoria Morozova, a daughter of the senior author.

Distribution ( Fig. 70 ). Tian Shan and Alay Range in Kyrgyzstan and Uzbekistan. Korb et al. (2017) recorded the species for the fauna of Kyrgyzstan as F. terminata .

Biology. Adults ( Figs 74–75 ) were collected with light traps from April to August at altitudes between 1,400 and 2,300 meters a.s.l. but mainly between 1,600 and 1,800 meters ( Fig. 73 ). It probably flies in two generations like F. terminata . Preimaginal stages are unknown. Local species of Salix and Populus could be the host plants.
