Ctenoneura bawangensis sp. nov.

( Figs. 6 View FIGURE 6 , 18 View FIGURE 18 )

Type material. Holotype: CHINA: Hainan: male ( IZCAS), eastern tree farm No. 2/ Dong’erlinchang (ĒΞήã), Mt. Bawangling , Changjiang County, 1200 m, 10.XII.2007, Jian Yao leg.

Diagnosis. C. bawangensis superficially resembles C. heixuanfeng , but can be distinguished from the latter by the following characters: 1) supra-anal plate with a large transparent area ( Fig. 6 D View FIGURE 6 ), while C. heixuanfeng has a large process ( Fig. 5 D View FIGURE 5 ); 2) apex of subgenital plate blunt ( Fig. 6 F View FIGURE 6 ), while possessing a barb towards left in C. heixuanfeng ( Fig. 5 F View FIGURE 5 ); and 3) the basal segments of cerci with flat expansions directed medially ( Fig. 6 C View FIGURE 6 ), while without expansions in C. heixuanfeng ( Fig. 5 C View FIGURE 5 ).

Description. Male. Body length 6.9 mm; overall length including tegmen 9.2 mm; pronotum length×width 2.1× 2.8 mm.

Coloration: Body dark brown. Head dark brown, antennae from scape to the second subsegment of flagellum and the apex dark brown, the rest flagellum yellow. Pronotum dark brown, with lateral margins of anterior yellow. Tegmina brown, wings hyaline with apex yellowish brown, venation brown. Legs dark brown, tarsi yellow, spines on the legs yellow. Cerci dark brown ( Fig. 6 A–B View FIGURE 6 ).

Head: unexposed ( Fig. 18 View FIGURE 18 A), vertex slightly flat, frons convex widely, eyes wide apart, interocular space greater than the distance between antennal sockets, ocelli small, antennae from the second subsegment of flagellum with much small yellow pubescence. Pronotum: subcircular, anterior margin truncated ( Fig. 18 View FIGURE 18 A). Tegmina and wings: fully developed extending well beyond end of the abdomen; M of tegmen with 4–6 branches, between R and M presents an intercalary vein, CuA with two branches ( Fig. 18 View FIGURE 18 B); wing with intercalary vein present, M bifurcate, CuA with 6 branches, CuP slender ( Fig. 18 View FIGURE 18 C). Legs: front femur type C1, anterior margin with several small setae ( Fig. 18 View FIGURE 18 D). Arolia small, tarsal claws symmetrical, simple. Abdomen: supra-anal plate in dorsal view with median strong protruded, apex with two small processes, the protruding part with median largely hyaline, lateral corners of supra-anal plate acute; cerci long, two basal segments coalesced, with narrow flat protruded part directed medially ( Figs. 6 C–D View FIGURE 6 , 18 View FIGURE 18 E). Subgenital plate asymmetrical, irregularly protruded towards right, apex of the protruding part blunt, the left part largely concave and truncate, the right part enlarged, right lateral margin with one small lobe, while left lateral margin with two ( Figs. 6 F View FIGURE 6 , 18 View FIGURE 18 F–G); in dorsal view, the distal lobe of the left lateral margin plate-formed, one slender stylus originated from the middle ( Fig. 6 E View FIGURE 6 , 18 View FIGURE 18 G), apex of the protruding part with two irregular processes, the basal one shallow, the distal one quite protruded, perpendicular to the horizontal level of the subgenital plate and pointing dorsally ( Fig. 18 View FIGURE 18 H). Genitalia: left phallomere: right margin of the lvp with a large triangular process medially, anterior slightly reduced, posterior margin with two processes, the processes forming a quadrate ring; the ldp with a thick stick-like cvp. Right phallomere: R1M tortuose, R2 with short rop and small slp, elp with basal part flat, distal portion slender and curved, apex round, R3 triangle, anterior round. Transverse sclerite (tvs): right apex sharp, thin, left portion curved, expanded ( Fig. 18 View FIGURE 18 I).

Female. Unknown.

Distribution. China: Hainan Island ( Fig. 4 View FIGURE 4 ).

Etymology. The species epithet is from the type locality Mt. Bawangling, in Hainan Province.

Natural history. Remains unobserved.
