Spininola qianfengensis sp. n.

( Figs 7–9 )

Type material. Holotype. male, Qianfeng District, 445 m, Guang’an , Sichuan Prov., 7.viii.2020, coll. Yanqing Hu & Yong Yu.

Diagnosis. Spininola qianfengensis is similar to S. trilinea ( Marumo, 1923) ( Figs 10–12 ) in the configuration of the male genitalia, but the two species can be easily distinguished by the forewing patterns: qianfengensis has a grayish forewing ground color, a grayish head, a grayish black collar and a pale grayish black stripe along costal margin, while trilinea has a grayish white forewing ground color, a white head and collar and a brown stripe along costal margin from the medial line to the wing base. In the male genitalia, qianfengensis has a shorter harpe, a parallel margin of ventral lobe of the valva, a thick part of sclerotized margin of the valva, a U-shaped saccus, and a straight aedeagus, while trilinea has a longer harpe, a tapered ventral lobe of the valva, a thin part of sclerotized margin of the valva, a V-shaped saccus, and a curved aedeagus.

Description. Adult ( Fig. 7 ). Wingspan 15 mm. Head grayish; antenna grayish brown, bipectinate in male; labial palpus short, stretched forward, mostly covered with grayish brown scales. Thorax brown, collar grayish black. Abdomen brown. Forewing ground color grayish, costal margin pale grayish black from the medial line to the wing base; basal line poorly visible; antemedial line blackish brown, arcuate; medial line poorly visible; postmedial line feeble, sinuous; subterminal line feeble; terminal line grayish brown; cilia blackish brown. Hindwing unicolorous, grayish brown; discal spot unconspicuous.

Male genitalia ( Figs 8 & 9 ). Uncus tapered, pointed at apex, sclerotized, longer than the spine bearing at top of ventral lobe of the valva; tegumen thin, about 3 times as long as uncus; valva divided at base; dorsal lobe broad distally, slender at base, sclerotized at costal margin; ventral lobe with parallel margin, a spine at apex, sclerotized at ventral margin; harpe smaller, S-shaped, sclerotized, sharp at apex; sacculus 2/3 as long as the ventral lobe of the valva; saccus small and U-shaped. Aedeagus straight; vesica without cornuti.

Female. Unknown.

Distribution. China (Sichuan).

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