Type material. Holotype: male, Mojiang county, 1515 m, Puer , Yunnan Prov., 15.vii.2023, leg. Yanqing Hu & Yong Yu. Paratypes: 2 males, with the same data as the holotype .

Diagnosis. Externally, the new species closely resembles Nola pinratanoides Hu, Wang & Han, 2015 , due to the uniform ground color of its forewings. However, the discernible differences are observed in their male genitalia: the new species has a broad tegumen, an apically thick and sharply curved harpe, a relatively narrow sacculus and a short aedeagus with a short spine, while N. pinratanoides has a relatively narrow tegumen, an apically thin and gradually curved harpe, a wide sacculus and a long aedeagus with a long spine.

Description. Adult ( Fig. 11 ). Wingspan 16–17 mm. Head blackish brown; antenna brown, bipectinate in the male; labial palpus short, stretched forward, mostly covered with dark brown scales. Thorax and collar covered with grayish black scales. Abdomen brown. Forewing ground color grayish brown; the basal line undistinguished; the antemedial line brown; the medial line undistinguished; the postmedial line formed by dots, blackish brown at the vein; the subterminal line formed by dots, pale dark brown, wavy; the terminal line undistinguished; cilia brown. Hindwing grayish brown; discal spot grayish black.

Male genitalia ( Figs. 12, 13 ). Uncus degenerated; tegumen relatively broad; valva bilobate near the base, the dorsal arm longer than the ventral arm; the dorsal arm sclerotized at the costal margin, rounded at the apex; the ventral arm sclerotized at the ventral margin; harpe sharply curved apically, pointed at the apex; sacculus slender; saccus V-shaped. Aedeagus short, with a short, anterio-laterally curved spine; vesica without cornuti.
