本文记载中国花蝽科原花蝽属Anthocoris Fallen新种6个,计为:黑角原花蝽A.atricarnis sp.n.(模式产地:云南),哀牢原花蝽A.ailaoanus sp.n.(模式产地:云南),杨氏原花蝽A.yangi sp.n.(模式产地:云南),刺突原花蝽A.armatus sp.n.(模式产地:云南),萧氏原花蝽A.hsiaoi sp.n.(模式产地:四川、陕西),秀原花蝽A.concinnus sp.n.(模式产地:西藏)。文章并记录此属的3个中国新记录种;并为已被占用的A.elongatus Zheng 1982命以新名:A.longiusculus nom.nov.

Anthocoris atricornis sp. nov. (figs. 1,7)Black, shining, pubescence long and dense. Head comparatively short, length 0.48, width 0.52. Antenna black, seg. length 0.18:0.54:0.34:0.36, seg. Ⅱ distinctly thicker than Ⅲ, hairs dark. Pronotum length 0.52, collar width 0:42, hind margin width 1.22, lateral margin straight, anterior half narrowly carinate, gradually broadened distad, posterior lobe rugulcse. Hemelytra uniformly piceus with basal 3/5 of exocorium pale testaceous, membrane greyish brown, with a pale spot behind the cuneus apical angle; exocorium length 1.20, cuneus length 0.73. Legs piceus. Clasper sickle-shaped (fig. 7). Body length 3.7.Holotype ♂, Yunnan (Lu-shui, 26N°, 98°8'E), 6.Ⅵ.1981. (kept in the Institute of Zoology, Academia Sinica, Beijing).Close to A. thibnanus Poppius and A. yun nanus Zheng, distinguished by shorter head, color and comparative length of antennal segments, more carinate pronotal lateral margin, more strongly curved and thicker clasper. The pubescence is shorter and the body is larger in comparison with yunnanus.Anthocoris ailaoanus sp. nov. (figs. 2, 8)Body elongate, shining, pubescence long and dense. Head black, length 0.46, width 0.46. Antennal seg. Ⅰ piceus, Ⅱ testaceous, gradually darkened distad, Ⅲ piceus, with basal 1/3 testaceous, Ⅳ piceus; seg. lengths 0.16:0.68:0.46:0.44. Pronotum black, length 0.46, collar width 0.37, hind margin width 1.04, lateral margin slightly concave, feebly carinate anteriorly; posterior lobe not rugulose, with shallow and sparse punctures, slightly sunken medially. Clavus brown, medially with a large yellowish spot, corium brown with basal 2/3 of exocorium whitish, cuneus testaceous, with inner half brown; membrane smoky, with white spots as in fig. 2; exocorium length 1.26, cuneus length 0.74. Femur yellow, with a subapical brown ring, tibia brown, gradually darkened distad, tibial hairs twice the tibial diameter or longer. Clasper angulate and slender (fig. 8) Body length 4.0.Holotype ♂, Yunnan (Mt. Ailao, 2450m. alt., 24°30'N, 101°E), 22. Ⅹ. 1982, (kept in Nan-kai University).Resembles to A. longiusculus Bu et Zheng, but body more slender, coloration of antenna and hemelytron differ, tibial hairs longer, outer margin of clasper conspicuously concave bas-ally.Anthocoris yangi sp. nov. (figs. 3, 9)Body elongate, shining. Head black, sometimes paler apically, comparatively narrow, length 0-56, width 0.46. Antenna] seg. Ⅰ, Ⅲ, & Ⅳ piceus, Ⅱ ferrugineous or light brown, darkened gradually toward apex, sometimes the basal 1/4 of Ⅲ light brown; seg. length 0.18:0.58:0.40: 0.40. Pronotum with pubescence sparse and moderately elongate, anterior lobe black, posterior lobe ferrugineous, brown or black, lateral margin nearly straight or slightly concave, callus large, occupying almost the whole anterior lobe, posterior lobe not rugulose, with shallow and sparse punctures. Hemelytral pubescence dense and long, clavus testaceous with apical half brown to picus, or gradually paler proximally and laterally, corium testaceous with apical 1/3-1/2 gradually darkened to brown or piceus, cuneus ferrugineous or piceus, membrane as shown in fig. 3, exocorium length 1.20, cuneus length 0.74.

Ailao, 2450 m. alt., 24°30'N, 101°E), 4. loration and longer pubescence.Anthocoris armatus sp. nov. (figs. 4, 10)Black and shining, pubescence long and dense, semierect. Head length 0.46, width 0.49. Antenna black, or seg. Ⅱ & Ⅲ ochraceous and darkened apically, seg. length 0.15:0.49:0.30: 0.36, hairs shorter or nearly equal to segment's diameter.
