The new species is similar to F. multicornuta Bidzilya & Nupponen, 2018 in both appearance and genitalia. It differs from the latter in the forewing mottled with brown scales at the base and from the base to basal 3/4 along the costal margin ( Fig. 4 ), in the male genitalia by the anellus lobes longer than the sacculus and the phallus with a U-shaped apical cornutus ( Fig. 24 ), and in the female genitalia by the ductus bursae with a flyer-shaped sclerite posteriorly ( Fig. 31 ). In F. multicornuta , the forewing has blackish brown scales along the costal, the dorsal and the terminal margins ( Fig. 5 ); in the male genitalia, the anellus lobes are shorter than the sacculus, and the phallus has a V-shaped apical cornutus ( Fig. 25 ); in the female genitalia, the ductus bursae has a sclerotized ribbon posteriorly ( Fig. 32 ). Description. Adult ( Fig. 4 ). Wingspan 17.0–18.0 mm. Head pale grayish yellow, frons cream white. Labial palpus cream white mottled with brown except first segment and basal 1/4 of second segment brown on outer surface. Antenna: scape grayish brown; flagellum grayish white, with brown rings. Thorax and tegula grayish brown, mottled with yellow. Forewing pale yellowish brown, with brown scales at base and from base to basal 3/4 along costal margin; brown spot at basal 2/3 of fold, at middle and end of cell respectively; cilia grayish brown, mixed with brown-tipped grayish white scales. Hindwing and cilia grayish brown. Fore-and midlegs dark brown with grayish white on outer surface, grayish white on inner surface, tibiae grayish white near middle and at apex, tarsi grayish white at apex; hindleg grayish white with brown scales, except fifth tarsomere dark brown. Male genitalia ( Figs 14 , 24 ). Tergum eight ovoid, with distally broadened anterolateral arms. Sternum eight sub-trapezoid; anterior margin shallowly emarginated, with slender anterolateral arms; posterior margin emarginated at middle, rounded posterolaterally.Uncus narrowed from base to basal 2/3, distal1/3 subparallel laterally; posterolateral lobe digitate, sclerotized, median protrusion sub-circular; ventral surface with strong setae. Gnathos stout, hooked, narrowly rounded at apex, distal 1/3 serrate on inner margin. Tegumen sub-triangular, anterior margin deeply emarginated to beyond anterior half; pedunculus with extended lobe at apex. Valva narrowed from base to apex, bent inward, with setae in distal 1/6; apex pointed, not reaching apex of gnathos. Sacculus slender, clavate, about 1/2 length of valva, rounded at apex. Anellus lobe very large, strongly sclerotized, basal 1/4 widely extended outward, distal 3/4 horn-shaped, bent outward; longer than sacculus. Vinculum narrow. Saccus subparallel to subapex, longer than sacculus. Phallus with two sclerotized lateral extensions of the phallus sheath and two cornuti: left extension long, curved in S-shape, with several teeth on distal 1/4, narrowed at distal 1/8; right extension curved at basal 3/5, with two teeth at distal 1/6; apical cornutus U-shaped, its right arm slightly longer than left arm, left arm with a tooth at 1/3 on outer margin; medial cornutus horn-shaped, strongly curved medially. Female genitalia ( Fig. 31 ). Papillae anales sub-oval. Apophyses posteriores about 1/4 length of apophyses anteriores. Sternite eight trapezoid, longer than wide, posterior margin emarginated triangularly at middle, with hairlike setae; medial sclerite cone-shaped. Ductus bursae broad and short, with flyer-shaped sclerite and longitudinal sclerotized folds, with numerous spines on inner surface. Corpus bursae ovoid-shaped, with numerous spines on inner surface posteriorly; signum being a plate with small teeth and two long spine-shaped processes, placed in middle of corpus bursae. Distribution. China ( Xinjiang ). Etymology. The specific name is derived from the Latin magnus and anellus , referring to the large anellus lobe of the male genitalia.
