Miracorizus punctatus Yao, Cai & Ren , sp. nov.

( Figs. 1 – 10 )

Description: Body narrow, about 2.8 times (male) or 3 times (females) as long as wide. Head slightly shorter than pronotum, surface distinctly granulate; antenna slender, slightly longer than head, pronotum, and scutellum combined, second segment about 1.4 times as long as third, 2 times as long as fourth; eyes somewhat prominent. Pronotum moderately transverse, nearly 2 times as wide as long, anterior margin about 0.5 times as long as posterior one, lateral sides convex, both anterior and posterior angles feebly rounded, surface densely punctate. Scutellum shorter than pronotum on median line, surface granulate similar to pronotum. All femora stout, over two times as thick as corresponding tibia, pro­ and mesofemora subequal to corresponding tibiae in length, third tarsomeres longest, almost 1.5 times as long as second; hind legs distinctly longer than fore and mid legs, tibia longer than femur, with densely setae, tarsi similar to fore and mid tarsi. Fore wing long, costal margin nearly straight, clavus and corium relative sparsely punctate; corium with distinctly thickened embolium, basal zone with two longitudinal sulci, nearly 0.8 times of hemelytra in length; clavus sticklike, in females basal of hid margin convex, nearly 6.5 times as long as wide, basal zone with a short longitudinal sulcus; membrane large, membranal suture curved, from which nearly 10 veins arising, these veins at middle forming some cells from which numerous radiating and anastamosing veins arise, basal portion with a distinct black spot. Structure of female genitalia as in Fig. 10 , ovipositor attending through last four abdominal segments, one­fourth as long as body.
