摘　　要：肩花蝽属(Tetraphleps Fieber)是花蝽科中的一个不大的属,世界已知共十余种。该属的已知生物学资料说明此类花蝽喜生活在针叶树上,捕食蚜虫和蓟马等,是这些森林害虫的一类潜在天敌。近年加拿大即曾试从印度和巴基斯坦引入此属的花蝽以防治球蚜Adclges piceae(Clark et al 1971;Kelton 1966,1978)。我国迄今尚无此属的明确记录,仅 Pericart(1972)在 T.aterrimus(J.Sahlberg)的分布记录中提及“天山”,但未注明国别,其分布图则似包括我国新疆天山的范围。在历年来收集的花蝽科标本中,我们共发现此属5个种,其中包括3个新种和一个中国新记录种,现分别记述于下。新种模式标本均存在南开大学生物系。描述中的量度单位为mm。Tetraphleps aterrimas (J.Sahlberg)1878Hebei(Weichang 41°55'N,117°50'E),Jilin(Mt.Changbai 42°10'N,128°10'E,740m.alt.,on Pinus densiflora),Xinjiang(Balikun 43°36'N,93°E)Telraphleps galenanoides Ghauri 1972,new recordSichuan (Lixian 31°40'N,102°54'E,2800-4000m.alt.),Yuman(Kumming 25°N,103°E,on Pinus sp.).Tetraphleps parallelus Bu et Zheng sp.nov.(figs.1,5,7)Body elongate,robust,parallel-sided.Head comparatively small,blackish brown,length 0.56,width 0.46,interocular space 0.26.Antenna blackish brown,seg.II testaceous subbasally,seg.length 0.20:0.62:0.34:0.34.Rostrum attaining to coxa of fore-leg.Pronotum testaceous with collar,callus and antero-lateral area black,length 0.59,collar width 0.40,posterior margin width 1.40,lateral margin slightly concave,flattened antero-lateral margin broad and reflexed,rugosities of posterior lobe extending to hind margin medially.Hemelytron testaceous,membrane greyish brown,exocoriurn length 1.50,cuncus length 1.0.Ostiolar peritreme slender Straight slightly narrowed centrally,apex free from the pleuron,with a fine ridge oa metapleuron in front of the peritreme (fig.5).Legs ferrugineous to piceus with tibia testaceous.Clasper as shown in fig.7.Body tength 4.7-5.0,width 1.6-1.8.Holotype paratypes 1 3 Sichuan (Lixian 32°N,102°50'E,2800m.alt),1963.Ⅷ.7,on Abies sp.Somewhat allied to T.raoi Ghauri,but with larger body,narrower head,longer ostiolar peritreme,lighter coloration and lateral margin of pronotum running a little more laterad.Tetraphleps yulongensis Bu et Zheng sp.nov.(figs.2,4,8)Ferrugineous to black.Head black,length 0.58,width 0.58,interocular space 0.34.Antenna black,seg.length 0.20:0.66:0.40:0.42,0.23:0.68:0.42:0.44,seg.Ⅱ somewhat club-shaped in Rostrum reaching apex of coxa of front leg.Pronotum with collar and callus black,posterior lobe ferrugineous,pronotal length 0.58,collar width 0.48,hind margin width 1.48,lateral margin broadly convex,flattened antero-lateral margin narrow and reflexed,rugosities on posterior lobe reaching hind margin.Hemelytron fer
