Diagnosis. 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.
