摘　　要：Fragments of nuclear ribosomal 28S rDNA D2 divergent domain, mitochondrial 16S rDNA, and COI partial genes of 15 species in the subgenus Singhardina Mahmood from China were amplified and sequenced. Molecular phylogenetic trees were constructed using maximum parsimony, maximum likelihood and Bayesian inference methods. Results from these methods revealed similar topologies with recognizable relationships among subclades. The phylogenetic relationship of four species groups of subgenus Singhardina Mahmood from China is discussed for the first time. The results show that Singhardina Mahmood forms a single lineage representing a monophyletic group. The Eurhadina （Singhardina） rubra species group newly proposed in this study is likely the most basal species group within Singhardina Mahmood. The E. （Singhardina） robusta species group is the sister group of the E. （Singhardina） mamata species group. Molecular evidence supports including the E. （Singhardina） vittata species group in the E. （Singhardina） punjabensis species group.测定了中国Singhardina亚属15个代表种的核糖体28S基因D2区和线粒体16S基因、COI基因部分序列,分别采用最大简约法、最大似然法和贝叶斯法构建分子系统树。系统发育树显示了相似的拓扑结构,明晰了各分支间的关系。首次探讨了中国Singhardina亚属4个种团间的系统发育关系。结果显示,Singhardina亚属构成了1个独立支系,代表1个单系群。本研究首次提出种团Eurhadina(Singhardina)rubra,并推测该种团可能是Singhardina亚属中最原始的种团。种团Eurhadina(Singhardina)robusta和E.(Singhardina)mamata为姐妹群。种团E.(Singhardina)vittata不能从种团E.(Singhardina)punjabensis中分出得到了分子数据的支持。
