description: Nola lufengensis Yu & Hu sp. nov.
(Figs. 1–5)
Type material. Holotype: male, Lufeng county, 1851 m, Chuxiong, Yunnan Prov., 13.vii.2023, leg. Yanqing Hu & Yong Yu. Paratypes: 3 males & 6 females, with the same data as the holotype.
Diagnosis. The new species belongs to the Nola angulata (Moore, 1888) species-group. In terms of external appearance, the new species closely resembles N. angulata when compared with two other species of the group (Nola eberti Hacker, 2012 and Nola shandura László, Ronkay & Ronkay, 2014). However, there are distinct diagnostic differences that can be observed as follows. In the forewings, the new species has a relatively short and thin antemedial line and an indistinct postmedial line, while N. angulata has a long and wide antemedial line and a conspicuous postmedial line. In the male genitalia, the new species has a triangular harpe with the sharped apex and a relatively slender aedeagus, while N. angulata has a finger-shaped harpe with the blunt apex and a relatively short and wide aedeagus. In the female genitalia, the new species has a punctiform and sclerotized area on the ductus bursae and an approximately rounded corpus bursae with two signa, while N. angulata has two sclerotized patches on the ductus bursae and a slender corpus bursae without signa.
Description. Adult (Figs. 1, 4). Wingspan 15–17 mm. Head gray; antenna brown, bipectinate in the male, filiform in the female; labial palpus short, stretched forward, mostly covered with gray scales. Thorax and collar covered with grayish brown scales. Abdomen brown. Forewing ground color gray, the costal margin blackish brown from the wing base to the antemedial line; the basal line undistinguished; the antemedial line black, thin, arc-shaped, wide before the cell; the medial line undistinguished, a black and triangular patch at costal margin; the postmedial line indistinct; the subterminal line pale brown, wavy; the terminal line indistinct; cilia gray. Hindwing grayish brown; discal spot undistinguished.
Male genitalia (Figs. 2, 3). Uncus degenerated; tegumen medium size; valva bilobate near the base, the dorsal arm almost as long as the ventral arm; the dorsal arm sclerotized at the costal margin, rounded at the apex; the ventral arm sclerotized at the ventral margin with a tiny spine at the apex; harpe approximately triangular, sharp at the apex; sacculus medium size; saccus U-shaped. Aedeagus moderate, without spine; vesica without cornuti.
Female genitalia (Fig. 5). Papillae anales short and broad; apophyses posteriores longer than apophyses anteriores; ostium rounded, slightly sclerotized at the margin; ductus bursae membranous, with a sclerotized area at the posterior part; corpus bursae slender at the posterior part, approximately rounded at the anterior part, about 3.5x as long as ductus bursae, with two signa, banded with a tiny spine.
Distribution. China (Prov. Yunnan).
Etymology. The species name is derived from the name of the type-locality, the Lufeng county, Prov. Yunnan.
