Margattea producta , sp. nov.

( Figs. 17–22 )

Description. Pronotum length width, 2 3mm; tegmen length, 11 mm; overall length, 13mm. Yellowish brown. Head with a brown band on vertex, frons yellowish white. Antennae dark brown, pronotal disk yellowish brown with dark brown spots and stripes.

Interocular space greater than the distance between the antennal sockets. Maxillary palps with segments 3 and 4 about equal, each distinctly longer than the fifth segment. Pronotum oval. Tegmina and wings fully developed extending well beyond the end of abdomen; wings with costal veins weakly thickened on distal halves, (8–9) bifurcated; median vein simple, cubitus vein with 2 complete branches, apical triangle small. The front femur Type B2, tarsal claws symmetrical with minute teeth on the ventral margins. The eighth tergum unspecialized.

Supra-anal plate with the mid of hind margin strongly concave, two sides produced, distal portion acute, curved downward. Subgenital plate asymmetrical, left side produced almost reaching the end of left style; interstylar margin slightly asymmetrical, not produced beyond the tips of the similar styles, left phallomere with a long, spine-like process, median phallomere slender, distal portion curved; right phallomere with its apical of hook-like portion acute, spine-like.

Female unknown.

Holotype: male, China: Xizang Zang Autonomous Region: Zhangmu, 24.vi.1975, Coll. Wang Zi-Qing.

Paratype: 1male, China: Xizang Zang Autonomous Region: Zhangmu, 14.vi.1980, collector unknown.

Comments: The species is similar to M. contingens with eighth tergum unspecialized, but can be distinguished by greatly concaved supra-anal plate.

Etymology: The Latin word productus meaning stretched or extended, refers to two sides of the supraanal plate produced.
