description: Nola nayongensis sp. nov.
(Figs 1–3)
Type material. Holotype: male, Nayong county, 2109 m, Bijie, Guizhou Prov., 1.viii.2021, leg. Yanqing Hu & Yong Yu.
Paratypes: 1 male, with the same data as the holotype; 1 male, Nayong county, 1731 m, Bijie, Guizhou Prov., 2.viii.2021, leg. Yanqing Hu & Yong Yu. The type specimens are deposited in Southwest University of Science and Technology (SWUST).
Diagnosis. Externally, the new species closely resembles Nola pinratanoides Hu, Wang & Han, 2015 (Figs 4–6), but the main diagnostic differences are found as follows: ground color of the forewing of the new species is pale brown with the white patches along the costal margin and a punctiform postmedial line. The forewing of Nola pinratanoides has a brown ground color, the diffused grayish white pattern at costal margin and wing base with a filiform postmedial line. In male genitalia, the new species can be separated by the combination of the following characters: a distally divided valva, a basally wide ventral lobe of valva, a bigger and wider sacculus, an apically rounded saccus and a shorter spine on the aedeagus. The male genitalia of Nola pinratanoides has a medially divided valva, a basally narrower ventral lobe of valva, a smaller sacculus, an apically pointed saccus and a longer spine on the aedeagus.
Description. Adult (Fig. 1). Wingspan 14–15 mm.
Head white; collar brown; antenna brown, white at the base, bipectinate in male; labial palpi white.
Thorax with blackish brown scales. Forewing ground color pale brown; costal margin with the white patches; vein Sc black at the base; basal line undistinguishable; antemedial line dark brown, arc-shaped; medial line undistinguishable; postmedial line consists of double lines, punctiform, wavy; subterminal line undistinguishable, but veins armed with dark and short lines; terminal line blackish brown; cilia pale blackish brown. Hind wing ground color pale grayish; discal spot pale black; cilia gray.
Abdomen brown.
Male genitalia. (Figs 2 & 3). Uncus not developed; tegumen of moderate size; valva divided distally; dorsal lobe of valva rounded apically, longer than ventral lobe of valva, costal margin sclerotized slightly; ventral valva relatively short, a small spine located at apex of valva, ventral margin sclerotized; harpe slender, incurved, tapering and pointed apically; sacculus elliptic, almost as long as the ventral lobe of valva; saccus V-shaped, rounded apically. Aedeagus cylindrical, with a short and curved spine apically; vesica without cornuti.
Female. Unknown.
Distribution. China (Guizhou).
Etymology. The specific name is derived from the name of type-locality.
