摘要Ceratovacuna和Pseudoregma是角蚜族（Cerataphidini）的重要类群，它们不仅在第一寄主上的虫瘿中产生兵蚜，而且在草本第二寄主上也产生角兵蚜。然而，由于以往研究中的采样偏差，这两个属的系统发育关系仍然没有定论。在本研究中，我们对Ceratovacuna和Pseudoregma的线粒体（细胞色素c氧化酶亚基I（COI）、细胞色素B（CytB））和细胞核（延伸因子-1 α（EF-1α）、长波视蛋白（LWO））基因进行了更广泛的采样和检测，并重建了它们的系统发育关系。系统发育分析，沿着与形态学证据，表明这两个属属于并系群的物种聚成三个主要组。Ceratovacuna和Pseudoregma作为一个整体的单系性普遍支持所有的分析。也支持Pseudoregma的单系性。估计的分歧时间表明，Ceratovacuna和Pseudoregma的多样化发生在大约10百万年。3个主要分支的基础关系分辨率较低，可能表明这两个属在晚第三纪经历了一次快速的辐射沿着其次级寄主的物种爆发。
Abstract Ceratovacuna and Pseudoregma are important groups in Cerataphidini (Hemiptera, Hormaphidinae) that not only produce soldier aphids in galls on the primary hosts but also produce horned soldiers on the herbaceous secondary hosts. However, due to sampling bias in previous studies, the phylogenetic relationships of these two genera remain inconclusive. In this study, based on more extensive sampling and examination of both mitochondrial (cytochrome c oxidase subunit I (COI); cytochrome b (Cytb)) and nuclear (elongation factor-1α (EF-1α); long-wavelength opsin (LWO)) genes, we reconstructed the phylogenetic relationships of Ceratovacuna and Pseudoregma. Phylogenetic analyses, along with morphological evidence, suggested that these two genera belong to the paraphyletic groups with species clustered into three main groups. The monophyly of Ceratovacuna and Pseudoregma as a whole was generally supported by all analyses. Monophyly of Pseudoregma was also supported. The estimated divergence times demonstrated that diversification of Ceratovacuna and Pseudoregma occurred approximately at 10 mya. The relatively low resolution for the basal relationships of the three main clades may indicate that these two genera have experienced a rapid radiation along with speciation burst of their secondary hosts during the late Tertiary.
