We performed molecular and morphological analyses to determine the generic limit of the genus Aulacorthum, including several species with controversial taxonomic histories. The sequences of four mitochondrial genes, COI, COII, srRNA and lrRNA, and one nuclear gene, EF1a, implied that Aulacorthum is not monophyletic, with Aulacorthum magnoliae and Aulacorthum nipponicum forming a clade that is not sister to other currently recognized Aulacorthum species. Morphometric analysis based on 20 morphological characters also showed that A. magnoliae and A. nipponicum exhibited morphological characteristics distinct from congeneric species. Based on these results, we propose a new genus, Neoaulacorthum ge. n., for A. magnoliae and A. nipponicum.
我们进行了分子和形态学分析,以确定短痣蚜属的属级界限,其中包括几个分类历史存在争议的物种。四个线粒体基因COI、COII、srRNA和lrRNA以及一个核基因EF1a的序列表明,短痣蚜属并非单系类群,其中木兰短痣蚜和日本短痣蚜形成一个分支,该分支并非其他目前公认的短痣蚜属物种的姐妹分支。基于20个形态特征的形态测量分析也表明,木兰短痣蚜和日本短痣蚜表现出与同属物种不同的形态特征。基于这些结果,我们为木兰短痣蚜和日本短痣蚜提出一个新属,新短痣蚜属(Neoaulacorthum ge. n.)。
