Fignya samkosa Wu & Han, 2024, sp. nov.

Fignya samkosa sp. nov. Figs 5, 13, 14 Type material. Holotype: Cambodia • ♂, Samkos, 7–8. ii. 2015, YS Bae leg., genit. prep. WuJ-1132-1, in NEFU. Paratypes • 2 ♂, same data as for holotype, genit. prep. WuJ-1131-1, all in NEFU. Diagnosis. The new species (Fig. 5) is most similar to the newly combined species, F. brachygnatha comb. nov. (Fig. 6), described in this paper. There is no obvious difference in appearance between these two species, but the male genitalia can be clearly distinguished: F. samkosa sp. nov. (Figs 13, 14) has a relatively straight valva, a small triangular hairy flap at the base of the valva, and a slender phallus; whereas the valva of F. brachygnatha comb. nov. (Fig. 15) is slightly curved inward, lacks the hairy flap at the base of the valva, and has a thicker phallus. The differences between F. samkosa sp. nov. and the other four Fignya species are provided in the remarks section of F. brachygnatha comb. nov. Description. Male. Adult. Forewing length 6.0– 6.5 mm, wingspan 14–15 mm (N = 3). Antennae filiform, brown. Labial palpi upcurved, brown. Head and thorax grayish-white with a tinge of pale brown; abdomen grayish-white to pale brown. Forewings grayish-brown with a series of serrated, golden and reddish-brown transverse lines, among which the antemedial line distinct, golden, zigzag; medial and postmedial lines fuzzy, reddish-brown; discal cell and tornus bear a total of three obvious white spots with black edges. Apex area white, brown on outer edge. Fringe golden. Hindwing reddish-brown; fringe long, pale yellow. Male genitalia. Uncus narrow and long, pointed apically. Gnathos spoon-shaped, slightly sclerotized and nearly membranous at the end, with densely packed small granular scobination on the surface. Tegument wide. Valva straight, lateral margins nearly parallel; valva with a hairy, small, triangular flap near the base; cucullus rounded. Juxta flat, shield-shaped, upper margin slightly concave in the middle. Saccus long, wide at base, then finger-like. Phallus slender, slightly curved, bifurcated from near the middle, each with a claw-like spine apically. Female genitalia. Unknown. Phenology and habitat. The type specimens were collected in February in the Phnom Samkos Wildlife Sanctuary of western Cambodia. The region has a typical tropical monsoon climate, characterized by distinct wet and dry seasons. The sanctuary’s vegetation includes a mix of evergreen forests, montane forests, and bamboo groves. The immature stages are still unknown. Distribution. Cambodia (Samkos). Etymology. The new species is named after its type locality, the Phnom Samkos Wildlife Sanctuary in western Cambodia.
