(Figs. 2–4)
Male. Forewing length 6.0– 6.3 mm (n=2). Head brown to blackish, slightly wider than pronotum; compound eyes black; antennae brownish to brown, scape darker. Pronotum brown, surface with light brown longitudinal median stripes, corners obtuse, posterior portion slightly widened; wings membrane subhyaline, veins brown; legs brownish to brown. Abdomen brown, terminalia dark brown.
Terminalia. Tergum 9 sclerotized, anterior margin with heavily sclerotized, posteromedial portion produced in darkly sclerotized protrusion which is trilobed with three similarly sized apical triangular sclerites, each covered by dense black scales (Figs. 2a, 3a). Subgenital plate of sternum 9 slightly wider than long and rounded apically, basally with an oval hirsute vesicle (Figs. 2b, 3b). Tergum 10 central plate with three separated sclerites, the mesal sclerite depressed and less sclerotized, posterior portion covered with a few hairs; transverse bars triangular, with a regular row of dense long hairs near outer margin (Figs. 2a, 3a, 3c). Lateral projections of tergum 10 a long and sclerotized spine-like plate which terminates in an acute point in lateral aspect, and the projections appearing as similar outline in dorsal, ventral and lateral views (Figs. 2a, 3a, 3f). Cercus curved upcurved medially in the usual manner, without apical spine (Figs. 2a, 2c). Epiproct flattened, regularly widened to arcuately notched apex (Figs. 2a, 3a, 3c–3e). Subanal lobe of large for genus, distinctly sclerotized, strongly upcurved apically at midlength, dorsal and ventral aspects each with two large curved hooks; the dorsal portion clearly bipartite, with two membranous finger-like apical lobes, in lateral and caudal view, and the mesoventral portion bears a pair of darkly sclerotized nipple-like projection (Figs. 2a–2b, 3a–3b, 4).
Female. Unknown.
Type material. Holotype male (HIST): China, Sichuan Province, Dujiangyan city, Qingchengshan, 1020 m, 30.8283 N, 103.7836 E, 2011.IV.15, leg. Xiaoli Duan. Paratype: 1 male (CAU), China, Sichuan Province, Liangshan Prefecture, Mianning County, Zhilei Nature Reserve, 2544 m, 28.9189 N 102.22300 E, 2019.VII.25, malaise trap, leg. Zhudong Liu and Zhiming Li.
Etymology. This specific name refers to the large spines on the subanal lobe.
Distribution. China: Sichuan Province.
Remarks. Rhopalopsole magnispina sp. nov. is a typical member of R. shaanxiensis group as proposed by Sivec et al. (2008) with strongly ornamental tergum 9 and large and complex subanal lobe. This species can be easily distinguished from other members of the group by the large hook-like spines on subanal lobe, trilobed posteromedial portion of tergum 10, and widened epiproct with arcuately incised apex.
