description: Spininola yuanjiangensis Yu & Hu sp. n.
(Figs 7–9)
Type material. Holotype. male, Yuanjiang county, 724 m, Yuxi, Yunnan Prov., 14.vii.2023, coll. Yan-Qing Hu & Yong Yu., in SWUST. Paratypes. 2 males, with the same data as for the holotype, in SWUST.
Diagnosis. Spininola yuanjiangensis somewhat reminds Manoba fasciatus (Hampson, 1894) (Fig.10) in external appearance. Nevertheless, S. yuanjiangensis has a rather unique external appearance compared with other congeneric species. In the male genitalia, S. yuanjiangensis shows a closer relationship with Spininola maliatthoides László, Ronkay & Ronkay, 2014. The diagnostic characteristics between the two species are as follows: S. yuanjiangensis has a slender uncus, a truncated process of the dorsal lobe of valva, a distally sharp ventral lobe of valva, a big and robust harpe, a slender sacculus and the aedeagus with protuberances, while S. maliatthoides has a short and distally triangular uncus, a sharp process of the dorsal lobe of valva, a distally blunt ventral lobe of valva, a slender harpe, a wider sacculus and the aedeagus without sclerotized markings.
Description. Adult (Fig. 7). Wingspan 15–16 mm. Head white; antenna pale brown, bipectinate in male; labial palpus short, directed forward, mostly covered with white scales. Thorax and collar covered with white scales. Abdomen brown. Forewing ground colour grayish white, the costal margin brown from the postmedial line to the wing base, the terminal area mostly brown; the basal line indistinguishable; the antemedial line blackish brown, visible before vein Sc; the medial line arc-shaped, black, edged inwardly with scales of brown colour; the postmedial line is formed from small black dots, curving outward towards the postmedial line along vein R 3, then curving inward and slightly sinuating towards the inner margin; the subterminal line pale brown, wavy; the terminal line formed from black dots; cilia brown. Hindwing grayish white; the discal spot grayish black.
Male genitalia (Figs 8 & 9). Uncus slender, blunt at apex, almost half the length of tegumen; tegumen short, wider medially; valva bilobate; the dorsal lobe of valva rounded distally, the sclerotized process exceeds the dorsal margin; the ventral lobe of valva short, tapering distally, sharp at apex; harpe S-shaped, big and robust, elongate, sharp at apex; sacculus longer than the ventral lobe of valva; saccus small and U-shaped. Aedeagus cylindrical, concave distally; vesica without cornuti; coecum comprises almost 1/5 of the length of aedeagus.
Female. Unknown.
Distribution. China (Yunnan).
Etymology. The species name is derived from the name of the type locality.
