Type material examined. Holotype (Figs 11, 43): China • ♂, “ STS- 40065 | Sejila Mountain, Linzhi City, | Xizang, China, | N: 29°37'5" | E: 94°39'38" | 5 - X- 2020 | h [Altitude] 4500 m (coll.

China • 5 ♂♂, 1 ♀, Sejila Mountain, Linzhi City, Xizang, China, 29°37'2"N, 94°38'30"E, 4-X-2020, h [Altitude] 4500 m (Pan Zhaohui and Chen Enyong leg.), unique IDs: STS- 32784, 32786, 32789 to 32792 (TAAHU). Diagnosis. The forewing length is 11.0–12.0 mm in males and 13.0 mm in the female. Dasypolia sejilaensis is externally reminiscent of D. vignai but is distinguished by its forewing shape, which has a straight costal margin and a more elongate apex, and the more diffuse forewing pattern in males, and the longer hindwing discal spot in both sexes. Additionally, compared to D. vignai, the reniform stigma of D. sejilaensis is situated closer to the forewing costa, and the pale suffusion on the transverse lines and stigmata is grey whereas it is brown in the congener. The male genital capsule of D. sejilaensis differs from D. vignai in the broader valva with a broader and less downcurved cucullus, the shorter but markedly thicker and upcurved ampulla (it is downcurved in D. vignai), the broader sacculus, and the less prominent and triangular valvula, which is more rounded in D. vignai. Additionally, the uncus, penicular lobe and juxta of D. sejilaensis are broader than in D. vignai. The phallus of D. sejilaensis is shorter and broader than in D. vignai (in proportion to the genital capsule). The vesicae of the two species are similar but the cornuti are more or less equal in size in D. sejilaensis whereas the distal cornuti of D. vignai are markedly longer and thicker than the proximal ones. In the female genitalia, D. sejilaensis can be distinguished from D. vignai in the longer apophysis anterior (in proportion to the ovipositor length), the narrower, more asymmetrically sclerotised and sideways curved ductus bursae (it is nearly straight in D. vignai), and the straight posterior section of the corpus bursae, which is sideways curved in D. vignai. A detailed comparison with another similar species, the sympatric D. cerritula is provided above in the diagnosis of the latter. Distribution. The species is currently known only from its type locality in southern Xizang province of China.
