The weevil genus Nephius Pascoe is for the first time reported from Vietnam (N. argus sp. nov.) and Taiwan (N. acastus sp. nov.). Until now the genus was attributed to the tribe Stromboscerini and contained nine nominal species and two subspecies known only from the type series. Phylogenetic analysis of one mitochondrial (COI) and two nuclear (ITS2 and 28S) markers strongly rejected monophyly of the tribe by placing the monophyletic Nephius as sister to a clade consisting of reciprocally monophyletic Dryophthorus and the rest of Stromboscerini. All herein used data (localities, DNA sequences, specimen images) are available online in public datasets dx.doi.org/10.5883/DS-NEPHIUS1 and dx.doi.org/10.5883/DS-NEPHIUS2.
象鼻虫属Nephius Pascoe首次在越南（新物种N. argus）和台湾（新物种N. acastus）被发现。在此之前，该属被归为Stromboscerini族，包含九个命名物种和两个仅在模式标本系列中已知的亚种。对一个线粒体（COI）和两个核基因（ITS2和28S）标记的系统发育分析强烈否定了该族的单系性，将单系的Nephius置于一个分支的姐妹位置，该分支由相互单系的Dryophthorus和Stromboscerini族的其他成员组成。本文中使用的所有数据（产地、DNA序列、标本图像）均可在公共数据集dx.doi.org/10.5883/DS-NEPHIUSl和dx.doi.org/10.5883/DS-NEPHIUS2中在线获取。
