黄斑蜂族的系统学研究:几何形态测量方法 (膜翅目:切叶蜂科)

摘要

利用采集于土耳其安纳托利亚中部(Middle Anatolia)的切叶蜂科6个种92头标本,选取虫体上的30个特征点(1andmarks)(其中前翅16个,后翅6个,头部8个),利用UPGMA等数值分类方法对不同属和种的亲缘关系进行了探讨.据此对一些种的归属和一些属的划分提出了一些与传统分类观点相同或不同的见解,但各种分析方法的结果都支持切叶蜂族Megachilini起源的单系性.%The classificatory schema in some groups of Megachilidae reorganized by means of shape differences in terms of the inter- and intra-specific and inter- and intra-generic and subgeneric deformations. The relative warps,UPGMA trees and PCA graphs obtained from 30 landmarks were shown. Both Anthidium cingulatum Latreille and A.florentinum (Fabricius) should better classify in the same subgenus Anthidium s. str. In the other case under the results of shape variation our results supported the hypothesis that Paraanthidium as a subgenus of Anthidium Fabricius. On the other hand Icteranthidium Michener and Paraanthidiellum Michener showed enough dissimilarity to be kept as separate genera. Our analysis also supported the monophyletic origin of Megachilini which was clustered as a separate group by all methods used.
