( Figs 1–3 )

Type material. Holotype. male, Yuqing county, 876 m, Zunyi , Guizhou Prov., 23–24.vii.2021, coll. Yan-Qing Hu & Yong Yu. Paratypes. 3 males, with the same data as the holotype ; 2 males, Yuqing county, 777 m, Zunyi , Guizhou Prov., 31.vii.2021, coll. Yan-Qing Hu & Yong Yu ; 4 males, Yuqing county, 876 m, Zunyi , Guizhou Prov., 29.vii.2021, coll. YanQing Hu & Yong Yu.

Diagnosis. The new species resembles Spininola nepali László, Ronkay & Ronkay, 2014 by the forewing patterns, but the two species can be easily distinguished by the configurations of the male genitalia. Compared with S. nepali , the new species has a slender uncus, a wide distally and long dorsal lobe of valva and a slightly sclerotized ventral lobe of valva. Spininola nepali has a short and pointed uncus, a short dorsal lobe of valva with a parallel margin distally and a short ventral lobe of valva with a strongly sclerotized and curved margin.

Description. Adult ( Fig. 1 ). Wingspan 14–17 mm. Head grayish white; antenna brown, bipectinate in male; labial palpus short, stretched forward, mostly covered with grayish scales. Thorax brown, collar gray. Abdomen brown. Forewing ground color grayish brown, costal margin brown from medial line to wing base, vein Sc black from antemedial line to wing base, terminal area pale brown; basal line undistinguished; antemedial line blackish brown; medial line poorly visible; postmedial line wavy, formed with black dots; subterminal line wavy, formed with black and short lines; terminal line blackish brown; cilia reddish brown. Hindwing unicolorous, grayish brown; discal spot gray.

Male genitalia ( Figs 2 & 3 ). Uncus slender, pointed at apex, almost as long as the spines located at top of ventral lobe of valva; tegumen thin, about 3x as long as uncus; valva divided at base; dorsal lobe broad distally, slender at base, two thirds sclerotized at costal margin; ventral lobe slightly sclerotized with parallel margin, a spine located at apex; harpe slender, S-shaped, sclerotized; sacculus 1/3x as long as the ventral lobe of valva; saccus small and V-shaped. Aedeagus long, slightly twisted; vesica without cornuti; coecum almost 1/5 × as long as aedeagus.

Female. Unknown.

Distribution. China (Guizhou).

Etymology. The species name is derived from the name of the type-locality.
