Rhopalopsole magnispina Li, Yang & Li View in CoL , sp. nov.

( Figs. 2–4 View FIGURE 2 View FIGURE 3 View FIGURE 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 View FIGURE 2 , 3a View FIGURE 3 ). Subgenital plate of sternum 9 slightly wider than long and rounded apically, basally with an oval hirsute vesicle ( Figs. 2b View FIGURE 2 , 3b View FIGURE 3 ). 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 View FIGURE 2 , 3a, 3c View FIGURE 3 ). 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 View FIGURE 2 , 3a, 3f View FIGURE 3 ). Cercus curved upcurved medially in the usual manner, without apical spine ( Figs. 2a, 2c View FIGURE 2 ). Epiproct flattened, regularly widened to arcuately notched apex ( Figs. 2a View FIGURE 2 , 3a, 3c–3e View FIGURE 3 ). 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 View FIGURE 2 , 3a–3b View FIGURE 3 , 4 View FIGURE 4 ).

Female. Unknown.

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.
