摘要

象鼻虫亚科(Ceutorhynchinae Gistel)是一个种类繁多的象鼻虫亚科,几乎分布于世界各地,具有相当重要的经济价值。然而,Ceutorhynchinae 的分类及其系统发育关系尚未完全确定。在这里,我们对 54 个ceutorhynchine 种类的有丝分裂基因组进行了测序。通过最大似然法和贝叶斯推断法对 13 个蛋白编码基因和 2 个核糖体基因数据集进行了系统发生分析。所有分析都得出了 A-C 三个支持度较高的支系。主成分分析表明,这些支系之间的密码子使用情况有很大差异,这表明栗鼠有丝分裂基因组的组成不对称。这增加了解决三个支系之间早期关系的挑战。对后期分化的解析更为稳健,所得出的拓扑结构基本上相互兼容,并与当前的分类学分类相一致。例外的是 Micrelus Thomson 属,它从 Ceutorhynchini 属转入 Egriini Pajni 和 Kohli 属(新位置),以及 Amalus Schoenherr 属,它转入 Phytobiini Gistel 属(新位置)。Amalini Wagner 1936 是 Phytobiini Gistel 1848 (syn. n.) 的初级异名。Coeliodini Lacordaire(新地位),一个以前被认为是 Ceutorhynchini 的初级异名的部落,被重新确立。我们的分析还澄清了将分类群归入 Scleropterini Schultze 和 Phytobiini 的困难。所有具有成虫跳跃能力的类群都属于 B 支系,该支系由 Cnemogonini Colonnelli、Hypurini Schultze、Mecysmoderini Wagner 和 Phytobiini 支系组成。通过密集的分类群取样和适当的分析方法,有丝分裂基因组数据提供了一个非常适合改进这一被忽视且物种丰富的分类群传统分类的系统发生学。

The phylogeny of ceutorhynchine weevils (Ceutorhynchinae, Curculionidae): Mitogenome data improve the resolution of tribal relationships

Ceutorhynchinae Gistel are a diverse weevil subfamily of almost worldwide distribution and considerable economic importance. Nevertheless, the classification of Ceutorhynchinae and their phylogenetic relationships are not yet fully resolved. Here, we sequenced the mitogenomes of 54 ceutorhynchine species. Phylogenetic analyses by maximum likelihood and Bayesian inference were performed on a dataset of 13 protein-coding and two ribosomal genes. All analyses recovered three well supported clades A–C. A principal component analysis shows that codon usage differs considerably between these clades, indicating a compositional asymmetry in ceutorhynchine mitogenomes. This increased the challenge of resolving the early relationships among the three clades. The resolution of the later diversification was more robust, and the resulting topologies were largely compatible with each other and with the current taxonomic classification. Exceptions are the genera Micrelus Thomson, which is transferred from the tribe Ceutorhynchini to Egriini Pajni and Kohli (new position) and Amalus Schoenherr, which is transferred to Phytobiini Gistel (new position). Amalini Wagner 1936 is a junior synonym of Phytobiini Gistel 1848 (syn. n.). Coeliodini Lacordaire (new status), a tribe previously regarded as junior synonym of Ceutorhynchini, is re-established. Our analyses also clarified the difficult assignments of taxa to the tribes Scleropterini Schultze and Phytobiini. All taxa with the ability to jump as adult beetles belong to clade B, which comprises the tribes Cnemogonini Colonnelli, Hypurini Schultze, Mecysmoderini Wagner and Phytobiini. With dense taxon sampling and appropriate analytical methods, mitogenome data provide a phylogeny well suited to improve the traditional classification of this neglected and species-rich taxon.
