This paper targets the nearly cosmopolitan weevil subfamily Lixinae. A phylogenetic analysis of one mitochondrial and two nuclear DNA fragments obtained from 87 Lixinae and 49 outgroup terminals strongly supports the monophyly of the subfamily. The molytine tribe Mecysolobini is the likeliest sister group of Lixinae; adults of both taxa share the likely synapomorphic condition of the greatly shortened labial palpi. Phylogenetic relationships within the subfamily are poorly resolved. None of three Lixinae tribes is recovered as monophyletic. The subfamilys oldest dichotomy is formed by a clade of two genera Rhabdorrhynchus plus Pachycerus sister to the rest of the subfamily. The genera Chromonotus, Larinus, Lixus, and Stephanocleonus are recovered as non-monophyletic. The genera Asproparthenis, Chromonotus, and Maximus form a strongly supported clade. The genus Eumecops is the likeliest sister to the clade formed by the genera Stephanocleonus plus Coniocleonus. The cleonine genus Scaphomorphus is a sister to a subset of externally most similar species of the genus Lixus; the same clade likely includes the genus Lixoglyptus not represented in the analysis. As an aside we provide a short summary of active flight in adult Cleonini.
本文针对近世界性象鼻虫亚科 Lixinae。对从 87 种象鼻虫亚科和 49 个外群末端获得的一个线粒体和两个核 DNA 片段进行的系统发育分析强烈支持该亚科的单系性。莫利蒂族 Mecysolobini 最有可能是象鼻虫亚科的姐妹群；这两个分类单元的成虫都具有缩短的下唇须的可能同源特征。该亚科内部的系统发育关系解析度较差。没有一个象鼻虫亚科部落被恢复为单系。该亚科最古老的二分法是由两个属 Rhabdorrhynchus 和 Pachycerus 组成的一个分支，与亚科的其余部分形成姐妹群。属 Chromonotus、Larinus、Lixus 和 Stephanocleonus 被恢复为非单系。属 Asproparthenis、Chromonotus 和 Maximus 形成一个强烈支持的分支。属 Eumecops 最有可能是与属 Stephanocleonus 和 Coniocleonus 形成的分支的姐妹群。Cleonine 属 Scaphomorphus 是与属 Lixus 中外部最相似的物种的一个分支的姐妹群；同一分支可能还包括未在分析中代表的属 Lixoglyptus。顺便说一句，我们提供了关于成年 Cleonini 主动飞行的简短总结。
