( Figures. 1E , 2E, K , 3E , 4E )

Urostylis trullata Kerzhner, 1966: 46 , 50.

DIAGNOSIS: Pronotum and scutellum with pale punctures partly; hemelytra with slightly dark punctures; membrane transparent with V-shaped dark marking ( Figure 1E ); lateral margin of genital capsule slightly rounded, apex relatively thick with setae in dorsal view ( Figure 2E ); process of genital capsule not exceeding dorsal wall of capsule and bifurcated in lateral view ( Figure 2K ), process broadly developed, convex apically ( Figure 3E ); stem of paramere rounded and relatively thick, curved subapically, with small protuberance laterally ( Figure 4E ).

DESCRIPTION: Male: Body oval and elongated, length 11.69–13.31. COLOR. mostly greenish. Head: generally greenish, sometimes reddish; antennae almost brown, apex of third, fourth and fifth segment dark brown; rostrum green, apex of fourth rostral segment dark brown. Thorax: pronotum with pale and dark punctures, sometimes with pale punctures entirely; anterior part of scutellum with pale punctures, posterior part with dark punctures, sometimes with pale punctures entirely; hemelytra with slightly dark punctures; membrane transparent with V-shaped brownish marking; legs almost green, sometimes reddish; base of tibia with dark band, apical part brown; third tarsal segment brown. Abdomen: entirely green. SURFACE AND VESTITURE: Body slgithly glossy, covered with silvery short pubescences; antenna with densely short pubescences; legs with setae. STRUCTURE. Head: width of head longer than length mandibular plate projected as long as clypeus dorsally; length of antennae longer than length of body, first segment longer than 2 times length of head; rostrum not reaching to midcoxae. Thorax: anterior and posterior margin of pronotum rounded; mesal length of scutellum longer than width; lateral margkin of hemelytra rounded; legs generally long; femur distinctly thick; first tarsal segment as long as third segment. Abdomen: margin rounded, not reaching to apex of membrane. GENITALIA: lateral margin of genital capsule slightly rounded, apex relatively thick with setae in dorsal view ( Figure 2E ); process of genital capsule not exceeding height of capsule, bifurcated in lateral view ( Figure 2K ), process broadly developed, its upper margin sinuate ( Figure 3E ); paramere rounded and relatively thick, curved subapically, with small protuberance laterally ( Figure 4E ).

Female: No females examined in this study.
