Sinochlora hainanensis Tinkham 1945, p 241 ; Eades et al. 2006.

Material examined

Two females, China: Hainan Island : Jianfengling , 9 July 1981, coll. Liu Yuanfu ( IZAS); three males, one female, same data as above, but deposited in MSIE; 10 males, at light, China: Hainan Island : Baisa County: Yingeling Nature Reserve , 1100 m, 27 August to 4 September 2005, coll. Liu Chunxiang ( IZAS) .

First description of male (noυ.)

Form and size large for the genus (male length of tegmen: male 48.5 mm; length of posterior femur: male 31.5 mm). Stridulatory file on underside of left tegmen with about 55 teeth ( Figure 3D ). Male tenth abdominal tergum strongly produced, distal quarter deflexed, split into two approximately triangular strongly diverging lateral lobes ( Figure 6A, B ). Male epiproct approximately trapezoid, much longer than wide, dorsal surface strongly concaved symmetrically, and without long black bristles in the ventral surface; basal margin broadly concave, lateral margin strongly constricted towards the apex, and with each posterior lateral corner extending into a long upcurved sharp spine ( Figure 6C, D ). Male cerci rather long, incurved, and conical. Male subgenital plate slightly upcurved, widest at basal third part, then strongly tapering, split from apical third, and both subparallel lateral lobes with minute styli ( Figure 6F ).

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

Measurements (mm)

Length of body: male 30.0, female 35.0; length to apex of ovipositor 40.0–42.5; length to tip of wing: male 61.0, female 67.0–73.0; length of pronotum: male 7.0, female 7.0; length of tegmen: male 48.5, female 56.0–57.0; largest width of tegmen: male 9.6, female 12.0; length of hind wing: male 53.5, female 62.0–63.0; length of anterior femur: male 8.5, female 9.0; length of median femur: male 13.0, female 13.5–14.0; length of posterior femur: male 31.5, female 36.0; ovipositor 12.0.

Variation

One specimen has triangular subgenital plate with straight lateral margin and emaginated apical margin, which is very different from the original description of Sinochlora hainanensis .

Remarks

The species is distinctly distinguished by male tenth abdominal tergum strongly produced, distal quarter deflexed, split into two approximately triangular strongly diverging lateral lobes, and male epiproct approximately conversely trapezoid, much longer than wide, and each posterior lateral corner extending into a long upcurved sharp spine, and without long black bristles in the ventral surface.

Distribution
