膜翅目扁蜂科各属间支序系统分析

为了探索膜翅目Hymenoptera扁蜂科Pamphiliidae各属之间的系统关系,利用支序分析的原理和方法对扁蜂科的9个属进行属间支序分析,结果表明将扁蜂科划分为腮扁蜂亚科Cephalciinae和扁蜂亚科Pamphilii-nae是合理的。现有的分类系统中将扁蜂亚科分为扁蜂族Pamphiliini和脉扁蜂族Neurotomini是合理的,各族的单系性得到证实。扁蜂族是一个单系群,由扁蜂属Pamphilius 齿扁蜂属Onycholyda (丝扁蜂属Pseudo-cephaleia 克扁蜂属Kelidoptera)构成;脉扁蜂族只含一个属,独自构成一个单系。现有的腮扁蜂亚科中各族的划分也得到支序分析的证实,腮扁蜂亚科这个单系群由直扁蜂族Caenolydiani (华扁蜂族Chinolydini 腮扁蜂族Cephalciliini)组成,华扁蜂族与腮扁蜂族是姐妹群,共同构成一个单系群。腮扁蜂族是由阿扁蜂属Acan-tholyda和腮扁蜂属Cephalcia构成的一个单系群。

Cladistic Analysis Base on Genera of Pamphiliidae (Hymenoptera)

The generic relationship of the family Pamphiliidae which is divided into 9 genera is analyzed by means of cladistic analysis.The results of cladistic analysis indicate that it is reasonable to divide Pamphiliidae into two subfamilies: Cephalciinae and Pamphiliinae.Subdividing Pamphiliinae into Pamphiliini and Neurotomini is supported by cladistic analysis.Pamphiliini is a monophyletic group,it consists of Pamphilius Onycholyda (Pseudocephaleia Kelidoptera);Neurotomini is another monophyletic group,which includes only one genus: Neurotoma.At the same time,the present system of Cephalciinae is supported by cladistic analysis,Cephalciinae is a monophyletic group too,which includes Caenolydiani (Chinolydini Cephalciliini).Monophyletic group of Cephalciliini consists of Acantholyda Cephalcia.
