康蚖群的系统发生和生物地理学的研究(原尾目:始蚖科)(英文)

应用HENNIG86系统发生分析程序,选择出成虫的有代表性的16个共同衍征,分析了与康蚖属相关各属的各个种类,得出了该类群的相关系统树。同时对特征的演化以及其扩散途径等也进行了讨论。文中还应用Page 1993的COMPONENT程序进行了生物地理学的分析;得到种类—地区支序图。其中康蚖属表现为典型的印度—太平洋分布型,而其姐妹群新康蚖属则兼有东洋区和全北区的分布型。至于分布地区的相互关系和在这些地区的分衍替代事件的发生等问题也作了初步的假想。

PHYLOGENY AND BIOGEOGRAPHY OF CONDEELUM GROUP (PROTURA:PROTENTOMIDAE)

Using the Hennig 86 phylogenetic analysis program to analyse the taxa in genera related to Condeellum, the phylogenetic relationships among the species are schemed on the basis of potential synapomorphies of the adults, represented by 16 characters. The character evolution and the route of dis-persal are also discussed. The cladistic biogeographic analysis is performed. The basal taxon Condeellum exhibits an Indo-Pacific distribution and the sister group Neocondeellum species exhibit a collective Oriental and Holarctic distribution. The distribution patterns and the vicariance events occurred in those areas are hypothesized.
