Urostylis westwoodii Scott, 1874: 362 .

Urostylis atrostigma Maa, 1947: 133 , 143 (syn. Hsiao 1977: 195).

DIAGNOSIS: Pronotum, scutellum, and hemelytra with dark punctures; anterior part of pronotum with slightly dark punctures, humeral angle with densely dark punctures; hemelytra with densely dark punctures; membrane transparent with dark marking ( Figure 1F View FIGURE 1 ); abdomen with dark spiracles; lateral margin of genital capsule strongly rounded, apex thin apically with short and long setae in dorsal view, ( Figure 2F View FIGURE 2 ); median process of genital capsule reaching to dorsal wall of capsule in lateral view, bifurcated laterally ( Figure 2F View FIGURE 2 ), the proximal branch of process swollen and tapering to the apex, the other branch of cylinder shaped ( Figure 3L View FIGURE 3 ); paramere relatively thick basally, especially projected in middle part, apex sharp and curved subapically, with hook-like process laterally ( Figure 4F View FIGURE 4 ).

DESCRIPTION: Male: Body oval and elongated, length 11.19–13.52. 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 dark punctures, anterior part with slightly dark punctures, poterior part with relatively densely dark punctures, humeral angle with densely dark punctures; scutellum with entirely dark punctures; hemelytra with entirely dark punctures; membrane transparent with dark marking; legs almost green, sometimes reddish; base of tibia with dark band, apical part brown; third tarsal segment brown. Abdomen: entirely green except for dark spiracles. SURFACE AND VESTITURE: Body slightly 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 margin 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 strongly rounded, apex thin apically with setae in dorsal view ( Figure 2F View FIGURE 2 ); median process of genital capsule reaching to the dorsal wall of capsule in lateral view, bifurcated laterally ( Figure 2F View FIGURE 2 ), the proximal branch of process swollen and tapering to the apex, the other branch of cylinder shaped ( Figure 3L View FIGURE 3 ); paramere relatively thick in basal part, especially middle part of paramere projected distinctly, apex sharp and curved subapically, with hook-like process laterally ( Figure 4F View FIGURE 4 ).

Female: Body oval and elongated, length 14.05. COLOR: as in male. SURFACE AND VESTITURE: as in male. STRUCTURE: as in male except for genital segment. GENITALIA: lateral seventh abdominal segment right angled, not prominent, central seventh abdominal segment slightly convex and flat; gonocoxites 8 large, triangular and not touching at apex, not reaching laterotergite 9; laterotergites 8 robust and wide, its apices thin and covered by laterotergite 9; laterotergites 9 elongated, with sinuose profile, apex spatulate and in contact ( Figure 5E View FIGURE 5 ); spermatheca semi coiled, simple widened at base of sclerotized area ( Figure 5J View FIGURE 5 ).
