Holotype (Figs 1, 14): male, “STS-88896, Beibeng Township, Motuo County, Linzhi City, Xizang, China, N: 29°24.351′, E: 95°16.974′, 12-Ⅴ-2017, h [Altitude] 781 m (coll. Pan Zhaohui)” gen. prep.

In male genitalia, the new species is distinguished by the tripartite sclerotized distal valvae structure. Nygmia wui sp. nov. resembles N. inornata (Wileman, 1910) externally, with nearly identical forewings and hindwings patterns, and the male genitalia share the following characteristics: Uncus digitiform and sclerotized; Valvae bifurcate, with sclerotized branches; Phallus constricted medially, broader at both base and apex; Vesica bearing a recurved, sclerotized spine basally (Wang 2010). But differs in the male genitalia: i) valvae distally trifurcated with dorsal branch markedly stouter, middle branch slender with its tip bent outward, ventral branch shorter and triangular or spiniform, while in N. inornata, the distal end of the valvae is four-branched, with one branch from the ventral margin further splitting into two small processes, the other three branches are distally acuminate; and ii) saccus is triangular, while in N. inornata it is bilobed with a medial emargination.</p><p>Description. Adults. Male. Forewing length 32–39 mm.</p><p>Head: Antennae with brown rami; frons pale yellow.</p><p>Thorax: Pale yellow. Abdomen dorsally with brown transverse stripes between segments.

Phallus narrow medially, thickened at both basal and distal ends; vesica with hook-like sclerotised spine at base.</p><p>Female. Similar to male. Forewing length 52–53 mm.</p><p>Head: Antennae rami brown. Frons yellowish-brown.</p><p>Thorax: Abdomen dorsally dark brownish-yellow, ventrally light brownish-yellow. Anal tufts dark yellow. Venter of both wings brown. Forewings venter with six irregular yellow spots along outer margin; hindwings venter with yellow marginal band.</p><p>Female genitalia: Anal papillae elongate, ear-like. Anterior apophysis ≈2 × length of posterior apophysis. Length of eighth abdominal segment equal to 0.5× anal papillae length. Sterigma elongate-labiate in shape, and strongly sclerotised. Ductus bursae broad and approximately 0.7× the length of corpus bursae. Corpus bursae pyriform. Signum heavily sclerotised, filiform-labiate.</p><p>Distribution. The new species is known only from Linzhi, Xizang, China.</p><p>Etymology.

No. STS-86106 (XAAHU).</p><p>Diagnosis: Nygmia damuensis sp. nov. is reminiscent of N. quadrangularis, N. marginata, and N. insulata, but it can be clearly distinguished from its congeners by possessing a single black spot on the outer margin of the forewing (vs. five spots in N. quadrangularis, seven in N. marginata, and eight in N. insulata). The male genitalia capsules are similar, but the new species can be differentiated by the narrow uncus with an elongated base, with a small, central, ridged protuberance at its base. In N. quadrangularis, the uncus base is semicircular and slightly broader, featuring a larger triangular central ridge at the base. Nygmia marginata exhibits a broadly rounded uncus base with a smaller triangular central ridge, while in N. insulata, the uncus base is wider, with prominently convex and enlarged lateral sides, and the central ridged protuberance is nearly bell-shaped at its base. In the new species, the cornuti cluster on the middle of the vesica are elliptical, and the sclerotized plates are semi-elliptical located at the distal end and upturned. The vesica of N. quadrangularis bears a pyramidal spinule cluster and a semi-oblong sclerotized plate, both connected at the middle portion, while in N. marginata bears a semi-elliptical spinule cluster in the middle portion and a tongue-like membranous structure at the distal end containing a semi-elliptical sclerotized plate and in N. insulata bears a single semicircular spine cluster distally at the phallus membrane, followed by a semicircular sclerotized plate.</p><p>Description. Adult. Male. Forewing length 51 mm.</p><p>Head: Antennae bipectinate, yellow with brown rami; Frons yellow (slightly brownish).</p><p>Thorax: yellow. Abdomen dorsally black; venter of abdomen dark yellow. Anal tufts yellow, slightly elongated. Forewing has a brown groundcolour with median portion, an irregular round spot, and marginal area pale yellow. A brown spot presented between veins M 1 and M 2, accompanied by a black punctate spot near marginal scales and parallel to the brown spot. Cilia yellow, interspersed with black scales between M 1 and M 2. Hindwings yellow, sparsely speckled with pale blackish-brown scales; marginal scales yellow.</p><p>Male genitalia: Uncus beak-shaped, broad at base, with a carinate ventrally. Valva rectangular tapering to apex, slightly longer than phallus, densely covered with long bristles; sacculus triangular and prominent. Saccus welldeveloped, tongue-shaped. Phallus with ventroapical depression. Vesica sack-like, with an upturned semi-elliptical sclerotized plate distally, a sub-oval cluster of dense cornuti medially, and a broad rectangular cluster of dense cornuti basally.</p><p>Female. Unknown.</p><p>Distribution. The new species is known only in Linzhi, Xizang, China.</p><p>Etymology. The specific epithet damuensis is derived from the type locality, Damu.
