Type material.

Holotype: China • ♂, Guizhou Province, Xingren City, Linggangshang , 1470 m, 29. vi. 2022, J Wu, B Gao & RT Xu leg., genit. prep. WuJ-1129-1 , in NEFU.

Paratypes • 3 ♂, same data as for holotype, genit. prep. WuJ-806-1 , 1130-1, all in NEFU .

Diagnosis.

The new species is not noticeably different in appearance from F. melkaya (Fig. 3 ), F. ravalba (Fig. 4 ), and the next new species, F. trigonum sp. nov. (Fig. 2 ), but it seems that the overall color of the present new species is lighter compared to the three species mentioned above. It can be clearly distinguished from others by the characteristics of male genitalia.

In the male genitalia, F. qiana sp. nov. (Figs 7 , 8 ) is most similar to F. trigonum sp. nov. (Figs 9 , 10 ), as both have almost flat or beveled cucullus and a large, bristled process at the basal part of the valva. However, F. qiana sp. nov. has a pair of stronger and asymmetrical apical spines on the juxta, with the left (when viewed ventrally) spine usually slightly longer than the right; a more elongated and finger-like saccus; a smaller, claw-like, curved cornutus at the base of the vesica; and lacks the triangular sclerite near the base of the vesica. In contrast, F. trigonum sp. nov. has a pair of thinner, almost equal-length, finger-like spines on the juxta apically; a shorter, wider, triangular saccus; a thicker and slightly curved cornutus at the base of the vesica; and a triangular sclerite near the base of the vesica. Additionally, F. qiana sp. nov. differs from F. melkaya (Fig. 11 ) and F. ravalba (Fig. 12 ) by the latter two having a rounded cucullus on the valva, a small bristled process at the base of the valva, and a shorter, stouter phallus.

Description.

Male. Adult. Forewing length 7.5–8.0 mm, wingspan 16–17 mm (N = 4). Antennae filiform, brown. Labial palpi upcurved, pale brown. Head and thorax grayish-white with a tinge of brown; abdomen grayish-white to pare brown. Forewings grayish-white with a series of serrated reddish-brown transverse lines, among which the antemedial line distinct, brown, zigzag; medial and postmedial areas of forewing, and tornus relatively darker, with two large, white, oval spots with black scales around the edges and a series of indistinct small circular spots near tornus, and a small, white, round dot near distal part of cell; postmedian line distinct, forming a broad, indistinct reddish-brown band extending from c. 3 / 5 of the costal margin from the wing base to tornus. Fringe grayish-white with a tinge of light brown. Hindwings reddish-brown, with dark brown scales mixed in the costal and inner margin areas; fringe light brown.

Male genitalia. Uncus short, pointed apically. Gnathos flat, fish-tail-shaped, comb-like distally. Valva wider at the base; inner side of the cucullus obviously protruding, causing the end of the cucullus to look flat or beveled; basal part of valva with a near-elliptical sclerotized plate, covered with dense, long bristles laterally; sacculus slightly swollen at base. Juxta flat, with a pair of asymmetrical, slender, sclerotized apical spines apically, the left one always slightly longer than the right. Saccus long, broad at the base, gradually narrowing to the middle, then finger-like at distal half part. Phallus slender, tubular, slightly curved, sclerotized at terminal part. Vesica bearing 4–5 cornuti in total, basal one large, hook-shaped; second one small, near the basal cornutus; subapical cornuti 1 or 2 in numbers, apical and subapical cornuti same in size.

Female genitalia. Unknown.

Phenology and habitat.

The type specimens were collected in June at an altitude of c. 1470 m. The collection site is close to a mixed coniferous and broad-leaved forest, with bamboo forest, bushes, and farmland surrounding it (Fig. 16 ). The immature stages are still unknown.

Distribution.

China (Guizhou).

Etymology.

The new species name is derived from the abbreviation of Guizhou Province in China, “ Qian ”, which is the type locality of F. qiana sp. nov.
