( Figures 1K, L , 3G , 9 A–G)

Type material

Holotype: male, China: Hunan Prov.: Dayong, Zhangjiajie , 10 September 1988, coll. Liu Xianwei ( MSIE).

Description

Male (holotype). Stridulatory file on the underside of left tegmen with about 68 teeth ( Figure 3G ). Tenth abdominal tergum produced backwards, basal half triangularly sulcate in the middle, lateral forcipate processes gently decurved in the apical half, and apical margin approximately flat in the middle ( Figure 9A, B ). Epriproct dorsally concaved, with black bristles in the middle and both lateral sides in ventral surface, basal part widest, gradually constricted and shaped into three upcurved spines at apex, among which the middle one is smaller than the lateral ones, directing caudad at the base, and curved craniad apically, and both lateral symmetrical ones directing caudad ( Figure 9 D–G). Cerci conical, rather long, slender, and slightly curved. Subgenital plate broad at the base and very deeply cleft at the basal third, and the long arms strongly recurved and terminated with minute apical styli ( Figure 9C ).

Color. Brownish green. Costal vein white and black, each tegmen with a black spot at the base of the green subcostal vein.

Female. Unknown.

Measurements of male (mm)

Length of body 28.0, length to tip of wing 58.0, length of pronotum 6.5, length of tegmen 46.5, largest width of tegmen 9.0, length of hind wing 51.5, length of anterior femur 8.0, length of median femur 12.0, length of posterior femur 29.0.

Remarks

The new species most closely resembles S. trispinosa except that its male epiproct has a smaller middle spine than two lateral ones at apex.

Distribution

China.
