( 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.
