摘　　要：选用寄生红蜡蚧的扁角跳小蜂属 (Anicetus) 6个种的 14个形态特征和 2个其他特征 (寄主种数和是否寄生软蚧 )作为内群性状 ,以柯氏花翅跳小蜂 (Microterysclauseni)作为外群 ,运用PAUP (Version4 0b10 )程序做了支序分析。所得支序树状图有如下参数 :树长 =2 8;一致性指数 =0 6 786 ;稳定性指数 =0 4 375。 6种扁角跳小蜂中 ,亲缘关系表示为 :(A annulatus ,((A rubensi,(A beneficus,A rarisetus) ) ,(A howardi,A ohgushii) ) )。软蚧扁角跳小蜂 (A annulatus)与其他 5个种的亲缘关系相对较远 ,与传统分类学观点一致。Fourteen morphological features,and other two traits (the number of hosts,and whether or not parasitic in soft scales) were selected as characters of in-group,those of Microterys clauseni as out-group,a cladistic analysis of phylogenetic relationships among six Anicetus species parasitic on pink wax scales was made with PAUP (version 4.0b10).This analysis resulted in a tree of,that is,(A.annulatus,((A.rubensi,(A.beneficus,A.rarisetus)),(A.howardi,A.ohgushii))).It has following parameters:length=28,consistency index=0.6786,retention index=0.4375.That A.annulatus is far away from other 5 species is in keeping with the traditional observation of taxonomy.
