摘要
对水螨群 9总科进行了系统发育分析 ,支序分析选用了 2 3个形态学特征和 3个生物学特征。据分析结果所揭示的 9总科间的系统发育关系和姐妹群关系 ,将水螨群 9总科划分为 5类 :拟水螨类 ,含冥绒螨总科 ;始水螨类 ,含溪螨总科 ;真水螨类 ,含古水螨类和新水螨类 ;古水螨类 ,含水螨总科、盾水螨总科和皱喙螨总科 ;新水螨类 ,含刺触螨总科、腺水螨总科、湿螨总科和雄尾螨总科。类间姐妹群关系为 :拟水螨类与始水螨类 +真水螨类为姐妹群 ,始水螨类与真水螨类 (古水螨类 +新水螨类 )为姐妹群 ,古水螨类与新水螨类为姐妹群。该文还就所提出的水螨群 5类 9总科的阶元排列建议与已有的观点进行了比较。
The phylogenetic relationships of 9 superfamilies of Hydrachnellae (=Hydrachnidia)were studied.The cladistic analyses were made using 23 morphological characters and 3 biological characters.A classification scheme,based on the phylogenetic relationships within Hydrachnellae,is proposed for 5 groups with 9 superfamilies.Pseudohydrachnidia is the most primitive group containing one superfamily (Stygothrombioidea);Protohydrachnidia contains one superfamily(Hydrovolzioidea);Euhydrachnidia consists of 2 groups Achihydrachnidia and Neohydrachnidia;the Achihydrachnidia contains three superfamilies(Hydrachnoidea,Hydraphantoidea,Eylaoidea)and Neohydrachnidia four superfamilies(Sperchontoidea,Lebertioidea,Hygrobatoidea,Arrenuroidea).Following sister groups are suggested:Pseudohydrachnidia and Protohydrachnidia+Euhydrachnidia;Protohydrachnidia and Euhydrachnidia(Achihydrachnidia+Neohydrachnidia);Achihydrachnidia and Neohydrachnidia.Comparisons with hypotheses by other authors are given.
