description: Ctenoneura helicata sp. nov.
(Figs. 11, 13 A, 16 H, 23)
Type material. Holotype: CHINA: Yunnan: male (BJFU), Menglong Town, Jinghong City, 14.V.1978, no collector recorded. Paratype: CHINA: Yunnan: 1 male (BJFU), same data as holotype.
Diagnosis. This species can be distinguished from other Chinese simulans -group species by the peculiar deep and narrow emargination on the left side of the subgenital plate (Fig. 16 H).
Description. Body length 6.5–7.0 mm; overall length including tegmen 11.0– 11.5 mm; pronotum length × width 1.9–2.3 × 2.6–3.0 mm, holotype is distinctly bigger than the paratype.
Coloration. Body brownish yellow. Head dark brown, antennae yellowish brown. Pronotal disk dark brown, lateral areas yellow, subtransparent. Tegmina brownish yellow, wings transparent, with RP brownish yellow; venations of both tegmina and wings dark brown. Legs, abdomen, cerci light brown (Figs. 11 A–B).
Head: slightly exposed (Fig. 23 A), vertex round, eyes wide apart, interocular space greater than the distance between antennal sockets, ocelli small, face with a Y-shaped convex, antennae with much small yellow pubescence. Pronotum: subcircular (Fig. 23 A). Tegmina and wings: fully developed extending well beyond end of the abdomen; tegmen with branches of R oblique, Sc slightly thickened, M with 5–6 branches, between R and M presents an intercalary vein, CuA minute, short, not bifurcate (Fig. 23 B); wing with intercalary vein present, interrupted, M bifurcate, one branch rebifurcate, CuA with 5–6 branches, CuP long and thin (Fig. 23 C). Legs: front femur type C1, with many spinules on the surface, one process appearing on the base of the hind margin (Fig.
23 D). Pulvilli absent, arolia small, tarsal claws symmetrical, simple. Abdomen: supra-anal plate in dorsal view transverse, simple, median with a transparent area; cerci long, pubescent, three segments of the base rounded (Fig. 11 C–D, 23 E). Subgenital plate asymmetrical, when observing it in the specimen, left with an deep emargination, with one small stylus on the left side (Fig. 16 H); when observing it separately, right with an small eds (Fig. 11 F, 23 F–G) and the stylus is clearly observed situate on a process (Figs. 11 E–F, 23 F–G); in dorsal view, the eds forming a groove towards right (Fig. 23 G); sgs present, slender and curved, basal portion expanded, flat and round, near the basal portion bent acutely, the rest slender, heliciform and the apex portion nested in the eds (Fig. 13 A, 23 H). Genitalia: left phallomere: right margin straight, with a small process, rectangular with the right margin; lvp with irregular extending process towards left, ldp with narrow but well-sclerotized cvp. Right phallomere: R1M with one elongated process near the apex and one small bent process near the base; R2 with rop very inflated and stout, slp quite strong and short, elp short, with membrane, apex round; R3 large, anterior apex round. Transverse sclerite (tvs): right apex sharpened, near the right bent obtusely, the bent point with one blunt process; left portion with two neighboring processes, one bigger than the other (Fig. 23 I).
Female. Unknown.
Distribution. China: South Yunnan (Fig. 3).
Etymology. The specific epithet “ helicata ” expresses the character that the distal portion of the sgs is quite spiral.
