Sinochlora trapezialis sp. n.

( Figures 1C, D , 3B , 4 G–M)

Type material

Holotype: male, China: Guangxi Prov.: Long’an, Longhushan Mt. , 29 August to 1 September 1995, coll. Liu Xianwei, Jin Xingbao, and Zhang Weinian ( MSIE).

Description

Male (holotype). Form and size moderate for the genus (length of male: tegmina 43.5 mm, posterior femora 29.0 mm). Stridulatory file on underside of left tegmen with about 65 teeth ( Figure 3B ). Male tenth abdominal tergum with central process strongly produced, distal half strongly deflexed, apical margin emarginated, and lateral processes indistinct ( Figure 4 G–I). Male epiproct approximately trapeziform, slightly wider than long, with dorsal surface strongly concave towards the inside symmetrically, without long black heavy bristles in the ventral surface; basal margin broadly concave, lateral margin gradually constricted towards the apex, and each posterior lateral corner extending into an upcurved sharp spine. Male cerci rather long, incurved, and conical ( Figure 4 J–L). Male subgenital plate slightly upcurved, split from apical half, and with small styli ( Figure 4M ).

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

Female. Unknown.

Measurements of male (mm)

Length of body 29.0, length to tip of wing 55.5, length of pronotum 6.3, length of tegmen 43.5, largest width of tegmen 8.5, length of hind wing 48.5, length of anterior femur 8.5, length of median femur 11.0, length of posterior femur 29.0.

Remarks

In having elongated deflexed central process and indistinct lateral lobes of male tenth abdominal tergum, the new species closely resembles S. stylosa from Guizhou Province in southwestern China. It differs from S. stylosa by the male epiproct being trapezoid with each lateral apex formed into an upcurved spine (not triangular with apex formed into a spine).

Distribution

China.
