摘  要:Pentatomomorpha is one of the most biodiverse infraorders among the true bugs(Hemiptera: Heteroptera). Phylogenetic relationships among the superfamilies within this infraorder have been uncertain, especially for the Eutrichophora. The previous studies were based on morphological characters, or just mitochondrial or nuclear genes, or only partial 18 S rDNA and COI. In this study, we used maximum likelihood(ML) and Bayesian inference(BI) based on massive molecular datasets(18S rDNA, 28 S rDNA, Hox and mitochondrial genes totaling 21 loci and 12,538 characters) to infer a robust phylogeny for this terrestrial group. Results strongly support the monophyly of all superfamilies; the superfamily status of Aradoidea and the following relationships:(Aradoidea +(Pentatomoidea +(Coreoidea +(Lygaeoidea + Pyrrhocoroidea)))) in Pentatomomorpha, and(Coreoidea +(Lygaeoidea + Pyrrhocoroidea)) in Eutrichophora. Our results suggest that sampling greater numbers of genes is an effective tool for resolving phylogenetic problems.蝽次目是蝽类昆虫(半翅目:异翅亚目)中物种多样性最为丰富的次目之一,其总科之间的系统发育关系尚未确定,尤其对于真毛点类。以往对于蝽次目系统发育关系的研究基于形态数据,或仅基于线粒体或核基因,或为18S r DNA和COI基因片段。本研究选取了大量分子数据(18S r DNA、28S rD NA、Hox和线粒体基因,共21个基因位点,12538 bp),利用最大似然法和贝叶斯方法推断蝽次目总科间的系统发育关系。研究结果支持各总科的单系性,扁蝽总科的总科级地位,蝽次目各总科系统发育关系(扁蝽总科+(蝽总科+(缘蝽总科+(长蝽总科+红蝽总科))))和真毛点类系统发育关系(缘蝽总科+(长蝽总科+红蝽总科))。研究表明选取多个基因作为分子标记为解决系统发育问题的有效途径。
