Sphaeronemoura campylura Qian & Du View in CoL sp. nov.

( Figs. 13–26 View FIGURES 13–24 View FIGURES 21–26 )

Adult habitus. A large sized species, macropterous. Head black, antennae black, palpi ash black. Pronotum trapezoid, dark brown, wider than long, rugosities scattered. Leg black. Wings ash black, venation black ( Figs. 13– 14 View FIGURES 13–24 ).

Male. Tergite 8 with dark brown rectangle-shaped lobe postmedially and extends to tergite 9 ( Fig. 15 View FIGURES 13–24 ). Tergite 9 medially membranous and sclerotized laterally, covered with setose ( Figs. 15, 19 View FIGURES 13–24 ). Hypoproct of sternite 9 small and rounded, apical projection tapering with slightly upcurved, blunt tip; vesicle elliptical and medially membranous ( Figs. 16, 17 View FIGURES 13–24 ). Tergite 10 medially membranous and sclerotized laterally, both sides of the posterior of medial membranous area with an obvious bluntly protuberant ( Figs. 15, 18, 22 View FIGURES 13–24 ), Paraproct inner lobe strongly sclerotized, apex pointed, almost adhered to the median lobe; median lobe also strongly sclerotized and apex pointed, but longer than the inner lobe; the outer lobe membranous ( Figs. 16, 17, 21 View FIGURES 13–24 ). Epiproct curled upward lightly, short finger-shaped in lateral view, apex indented medially ( Figs. 18, 19 View FIGURES 13–24 ). Dorsal sclerite more sclerotized laterally ( Figs. 17, 18 View FIGURES 13–24 , 25 View FIGURES 21–26 ); Middle of ventral sclerite with two sclerotized stripes ( Figs. 17 View FIGURES 13–24 , 25 View FIGURES 21–26 ); flagellum longer, upward and the apex pointed in dorsal view ( Figs. 15 View FIGURES 13–24 , 25 View FIGURES 21–26 ), strongly bent downwards at the base, apex curved downwards in lateral view ( Figs. 18, 19 View FIGURES 13–24 ). Cercus with dense setae, curved upward, terminal slightly trifurcate ( Figs. 15, 19, 23, 24 View FIGURES 13–24 ).

Female. Sides of anterior of sternum 7 with a sclerotized irregular spot, pregenital plate nearly elliptical and dark brown, covering most of sternite 7, overhanging the sternum 8 and indent semicircle in the middle of the posterior. Subgenital plate yellowish, a triangle-shaped sclerotized spot in the middle and a circular spot on both sides, the vaginal lobes under each of the circular spot that is an approximates teardrop-shaped sclerites. Sternite 9 dark brown, with a narrow trapezoid membranous indentation on the middle of the anterior margin.

Type material. Holotype male, CHINA: Yunnan Province, Zhaotong City, Yongshan County, Xisha Township , 28°18’17” N, 103°59’1” E, 805m, 22 Feb. 2017, Leg. Yu-Han Qian, Qin Huang, Jia Lin ( ICSFU) GoogleMaps . Paratypes: 1 female, same data as holotype ( ICSFU) GoogleMaps , 1 male, CHINA: Yunnan Province, Zhaotong City, Yiliang County, Xiaocaoba Reserve , 27°19’41” N, 104°17’9” E, 1661m, 26 Feb. 2017, Leg. Yu-Han Qian, Qin Huang, Jia Lin ( ICSFU) GoogleMaps .

Etymology. The Latin name “ campylura ” means curving cercus referring to the distinctly shape of cercus.

Remarks. The new species is closely related to S. songshanna Li & Yang, 2009 from Beijing, but the male of S. campylura is distinguished by the apex of the medial lobe acute and longer than inner lobe of the paraproct, outer paraproctal lobe membranous, and the terminal of cercus slightly trifurcate. The male appears also related to S. grandicauda ( Wu, 1973) known from Sichuan Province also of southwestern China, but the new species was a rectangle-shaped lobe on the tergite 8. The female shares some similarities with S. songshana , S. formosana Shimizu & Sivec, 2001 , S. plutonis and S. separata , but the female of S. campylura can be distinguished by the much longer subgenital plate of sternum 8 and the semicircle posterior medial concavity of sternum 7 overlapping sternum 8.
