( Figs. 1–3 View FIGURE 1 View FIGURE 2 View FIGURE 3 )
Adult habitus ( Fig. 1a View FIGURE 1 ). General color brown to dark brown. Head dark brown, antennae uniformly brown to dark brown, palpi lighter; compound eyes black. Thorax brown to blackish; legs brown to dark brown, with yellow brown band on femora, the band on foreleg narrower; tibiae yellow brown, but apex gradually becoming darker, tarsi brown; forewing brown to dark brown with scattered light spots.
Male ( Figs. 1–3 View FIGURE 1 View FIGURE 2 View FIGURE 3 ). Forewing length 6.5–7.1 mm, hindwing length 5.8–6.2 mm (n=20). Tergum IX ( Fig. 2a View FIGURE 2 ) sclerotized, distinctly constricted medially, bearing medially interrupted row of tiny black spines along midposterior margin. Sternum IX basally with claviform vesicle, about half length of hypoproct; hypoproct broad and rectangular at basal half, distal half triangular in outline, distally rounded ( Fig. 2b View FIGURE 2 ). Tergum X mostly sclerotized, with anteromedial portion membranous ( Fig. 2a View FIGURE 2 ). Cercus slightly sclerotized, nearly cylindrical with narrower tip, length ca. 2x width. Epiproct ( Figs. 1b–d View FIGURE 1 , 2c–d View FIGURE 2 , 3a View FIGURE 3 ) long and recurved, nearly parallel-sided, with a weak subapical lateral constriction in dorsal view and a weak apical incision ( Figs. 2d View FIGURE 2 , 3d View FIGURE 3 ); ventral sclerite strongly sclerotized and nearly parallel-sided in lateral aspect, apically extending over dorsal sclerite forming a short upcurved flagellum ( Figs. 2d View FIGURE 2 , 3d View FIGURE 3 ). Paraproct inner lobe triangular and apex projecting near the base of epiproct ( Figs. 1e View FIGURE 1 , 3b View FIGURE 3 ); median lobe forming a sclerotized strip-like structure, mostly fused with inner lobe but with a short, isolated, narrow tip; outer lobe darkly sclerotized, generally adjacent to median lobe and club like; its apex curved dorsally and nipplelike ( Figs. 1e View FIGURE 1 , 2a–b View FIGURE 2 ).
Female ( Figs. 1f View FIGURE 1 , 2e View FIGURE 2 ). Forewing length 6.9–7.8 mm, hindwing length 5.8–6.9 mm (n=10). Sternum VII membranous, posteromedial portion with a darkly sclerotized hexagonal pregenital plate, about ¼ width of the segment. Sternum VIII with large trapezoidal sclerotized subgenital plate covering the entire length and ½ width, posterior margin barely reaching the anterior margin of sternum IX; paired paragenital plate is brown and generally triangular with curved margins, located at the posterolateral corner of the subgenital plate, inner portion fused with center of subgenital plate, which also can be seen through subgenital plate. Sternum IX heavily sclerotized, anteriorly forming a produced trapezoidal extension with a shallow anterior arcuate notch. Sternum X and paraprocts sclerotized and typical.
Type material. Holotype: male ( CAU), China: Xizang, Linzhi, Sejilashan , 4030 m, 29.6167°N, 94.6053°E, Malaise trap, 2017.V.5-VI.5, leg. Qicheng Yang.

Etymology. The name refers to Sejila Mountain, where the types were collected.
Distribution. Presently known only from the type locality, Sejilashan of southeastern Xizang.
Remarks. Indonemoura sejila is most similar to I. nigrihamita concava Li & Yao, 2017 (in Li et al. 2017b) described from Sichuan. However, the new species can be easily separated from I. n. concava by the median lobe of the paraproct that bears a sclerotized strip-like structure ending in a narrow tip and spineless ventral sclerite of the epiproct. For I. n. concava, the paraproct median lobe is spine-like with a hook-like apex and the ventral sclerite of the epiproct bears short black spines along an obscure ventral ridge (figs. 2e–f in Li et al. 2017b).
