Sinochlora nonspinosa sp. n.

( Figures 1E, F , 3C , 5 A–D)

Type material

Holotype: male, China: Guangxi Prov.: Napo, Defu , 1300 m, 16 August 1998, coll. Huang Fusheng ( IZAS).

Description

Male (holotype). Form and size smaller for the genus (length of male: tegmina 42.0 mm, posterior femora 27.0 mm). Stridulatory file on underside of left tegmen transversely split from the middle, with about 70 teeth ( Figure 3C ). Male tenth abdominal tergum with central process produced, gradually narrowed, apical margin rounded, and each lateral one distinctly present as a small round lobe ( Figure 5A, B ). Male epiproct triangular, dorsally strongly concaved entad, and with long black heavy bristles in apical part of ventral surface, and apical part upcurved, gradually tapering into an obtuse finger-shaped process at apex. Male cerci rather long, incurved, and conical ( Figure 5C ). Male subgenital plate strongly upcurved, split from apical third, and with small styli ( Figure 5D ).

Color. Deep foliage-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 25.0, length to tip of wing 52.0, length of pronotum 5.5, length of tegmen 42.0, largest width of tegmen 7.5, length of hind wing 47.0, length of anterior femur 7.0, length of median femur 10.5, length of posterior femur 27.0.

Remarks

The new species closely resembles S. υoluptaria in male tenth abdominal tergum with central process strongly produced far beyond the somewhat distinct lateral lobes, but distinctly distinguished from the latter in the small size, the shape of the male subgenital plate and male epiproct triangular with apex obtuse and upcurved.

Sinochlora tibetensis sp. n. ( Figures 3I, J , 5I, J , 11A , C–H)

Type material

Holotype: female, China: Tibet: Motuo , 1550 m, 30 October 1982, coll. Han Yinheng ( IZAS) . Paratypes: one female, same data as in holotype but coll. Lin Zai ( IZAS) ; China: Tibet: Motuo, one female, Miri , 800 m, 16 November 1998, coll. Yao Jian ( IZAS) ; one female, Zhucun , 16 November 1998, coll. Yao Jian ( IZAS) ; five males, at light, China: Tibet: Motuo, Aniqiao , 1080 m, 29.32874 ° N, 95.14866 ° E, 13 August to 1 September 2006, coll. Liu Chunxiang ( IZAS) .

Description

Female (holotype). Size larger for the genus (length of tegmen: male 55 mm, female 56.0– 57.0 mm; length of posterior femur: male 33.5 mm, female 36.0 mm). Form, coloration, fastigum verticis, and pronotum also similar to the congenera. Tegmen with Rs bifurcate and given off slightly after the middle, and R stem also with three other lateral branches.

Female tenth abdominal tergum approximately trapeziform, with apical margin slightly obtuse. Cerci short, conical, suddenly sharpened into a spine at apex. Subgenital plate triangular, wider than long, with slightly convex lateral margin and obtuse emarginated apical margin ( Figure 5I ). Ovipositor similar to other congener ( Figure 5J ).

Male. Stridulatory file on underside of left tegmen with about 74 stridulatory teeth ( Figure 11A ). Tenth abdominal tergum with each lateral lobe rather long and strongly inclined downwards, the median process large, declined from base to center on the dorsal surface, gradually constricted toward both swollen lateral apices, and extending beyond the apices of the lateral lobes ( Figure 11C, D ). Epiproct smaller, approximately trapezoid, slightly wider than long, dorsally concave entad, with numerous black bristles in the ventral surface, and just bearing three small round lobes at apex, among which the middle one is distinctly smaller than both the lateral ones ( Figure 11F, G ). Male subgenital plate with apical two-fifths incised, and the forked processes gently recurved ( Figure 11H ).

Color. Deep foliage-green. Costal vein white and black, each tegmen with a black spot at the base of the green subcostal vein. Apical half lateral lobes of male tenth abdominal tergum black. Male epiproct marginalized black lateral stripes, and also with black half apical part.

Measurements (mm)

Length of body: male 32.0, female 35.0; length of pronotum: male 6.2, female 7.0; length to apex of ovipositor: 34.5–39.0; length to tip of wing: male 66.0, female 66.5–70.0; length of tegmen: male 55, female 56.0–57.0; largest width of tegmen: male 7.0, female 12.0; length of hind wing: male 60.0, female 62.0–63.0; length of anterior femur: male 7.5, female 10.0–10.5; length of median femur: male 13.5, female 14.0–15.0; length of posterior femur: male 33.5, female 36.0; length of ovipositor 12.0.

Remarks

The new species differs from other Sinochlora species by the larger size, structure of male tenth abdominal tergum, male epiproct, and female widely triangular subgenital plate. It slightly resembles S. longifissa in the shape of female subgenital plate, but differs by the larger size, male abdominal apex and the female subgenital plate with obtuse emarginated apical margin (not angular emarginated). It resembles S. hainanensis in size but differs by the male abdominal apex and the shape of female subgenital plate.

Distribution

China.
