description: Spininola zhaotongensis Yu & Hu sp. n.
(Figs 1–3)
Type material. Holotype: male, Zhaotong, 2249 m, Yunnan Prov., 11.vii.2023, coll. Yan-Qing Hu & Yong Yu., in SWUST. Paratypes: 3 males, with the same data as for the holotype; 2 males, Nayong county, 1996 m, Bijie, Guizhou Prov., 1.viii.2021, coll. Yan-Qing Hu & Yong Yu, in SWUST.
Diagnosis. Spininola zhaotongensis is similar to Spininola subvesiculalis Hu, Wang & Han, 2012 (Figs 4–6), but is readily distinguishable by the following characteristics: in the forewings, S. zhaotongensis ground colour is gray with intermixed brown and a postmedial line formed from short and black stripes, while S. subvesiculalis has a grayish white ground colour with suffusion of black and a consecutive zigzagging postmedial line; in the male genitalia, S. zhaotongensis has a triangular uncus, a relatively short dorsal lobe of valva with the dorsal margin, sclerotized only till half, a distally straight harpe and the coecum of aedeagus with the wider caudal end, while S. subvesiculalis has a slender uncus, a long dorsal lobe of valva with dorsal margin sclerotized to 2/3, a slightly curved and elongate harpe distally, and a cylindrical coecum of aedeagus.
In addition, Spininola zhaotongensis also resembles Spininola unicata László, Ronkay & Ronkay, 2014. The diagnostic characteristics separating these two species are as follows: in the forewings, S. zhaotongensis has a brown vein Sc at the wing base and a straight postmedial line between vein Sc and vein M 2, while S. unicata has a black vein Sc at the wing base and a zigzagging postmedial line between the veins Sc and M 2; in the male genitalia, S. zhaotongensis has a short dorsal lobe of valva, a distally straight and short harpe and a slender aedeagus with a wider coecum, while S. unicata has a long dorsal lobe of valva, a distally curved and elongate harpe and a relatively broad aedeagus with a cylindrical coecum.
Description. Adult (Fig. 1). Wingspan 21–22 mm. Head white; antenna brown, bipectinate in male; labial palpus short, stretched forward, mostly covered with brown scales. Thorax brown, collar covered with grayish white scales. Abdomen brown. Forewing ground colour gray, the costal margin brown from the antemedial line to the wing base, and the terminal area mostly grayish brown; the basal line indistinguishable; the antemedial line blackish brown, with a big dot on vein Sc; the medial line grayish brown, feeble, with a black brown patch on the costal margin; the postmedial line formed with the small and black lines; the subterminal line grayish brown, feeble; the terminal line with darker brown dots; cilia blackish brown. Hindwing pale blackish brown; the discal spot pale black.
Male genitalia (Figs 2 & 3). Uncus triangular, pointed at apex, almost 2/3× shorter than harpe; tegumen of medium size; valva bilobate; the dorsal lobe of valva broad distally, slender at the base, sclerotized till half at costal margin; the ventral lobe of valva almost as long as the dorsal lobe of valva, with several spines located at the apex; harpe S-shaped, slender, medium sized; sacculus shorter 1/3× than the ventral lobe of valva; saccus small and Ushaped. Aedeagus cylindrical; vesica without cornuti; the length of coecum almost 1/4 of the length of aedeagus, coecum expanded at the end.
Female. Unknown.
Distribution. China (Yunnan).
Etymology. The species name is derived from the name of the type locality.
