(Figs. 2–5, Fig. 15)

Color: Body brown, with yellowish patterns; transverse bands on pronotum yellow; corium and membrane separated by a pale line; male’s basal 3 segments of abdominal ventral dark whereas female’s body ventral yellowish.
Structural Characteristics: Head rounded and broad in both sexes and vertex slightly produced in male, face flat; pronotum rugulose, with 8–9 transverse yellow bands, bands a little wider than dark interspaces and often bifurcate; lateral angle of pronotum rounded; lateral lobe of prothorax long and apex rounded (Fig. 2 -a); metaxyphus triangular and its length almost equal to width of base; pala of male broad, middle obliquely raised as a ridge, with a curving peg row consisting of 29–31 pegs; upper palmar bristles continuous (Fig. 3); front femur with two rows of spines, 5–6 spines tending forward and 2 backward; strigil subrounded, consisting of 4–5 combs (Fig. 4); median setiferous lobe of 7th abdominal tergite narrow and triangular, a little curved, apical margin rounded; male genital capsule as in Fig. 5; right paramere of male acinaciform, gradually narrow from base to apex (Fig. 2 -b); left paramere of male as shown in Figs. 2 -c and 2-d.
Etymology: Named for Dr. Wenjun Bu, an entomologist specializing in Heteroptera.
Types: Holotype: 3, CHINA Yunnan (Yuanjiang), 2010m, 2007. VII.17, Xu Zhang leg.; paratype: Ƥ, CHINA Yunnan (Yuanjiang), 2010m, 2007. VII.17, Pengzhi Dong leg.; 2 3, CHINA Yunnan (Mt. Shizi Wuding), 1986. VIII.7–9, Leyi Zheng leg.; 33 2ƤƤ, CHINA Yunnan (Baoshan), 1979. VIII.22, Huanguang Zou & Jianxin Cui leg.. All types were deposited in NKUM.
Discussion: The new species is similar to Cenocorixa blaisdelli (Hungerford) in its male pala, but the shape of right paramere, shape of the median setiferous lobe of the 7th abdominal tergite, and the feature of strigil are obviously different.
