Molecular phylogenetics of the Clupeiformes based on exon-capture data and a new classification of the order

The sequence alignment or 1,165 loci of 66 clupeiform species and five outgroups. The loci were filtered for more than 70% taxa having sequences for each locus. Analyzing the data, we reconstructed a robust phylogeny of the Clupeiformes based on thousands of nuclear coding sequences obtained through target enrichment and curated for phylogenetic informativeness. We confirmed that the Clupeiformes is monophyletic, and Denticeps is sister to the Clupeoidei. Dussumieriids in their former understanding are polyphyletic, as Spratelloididae being sister to all other clupeoids. Sundasalanx belongs to Ehiravidae, but with deep split to other ehiravine species. A time tree of the Clupeiformes was calibrated with new fossil data and an updated classification of the Clupeiformes is provided.

序列比对或66个鲱形目物种及其五个外群中的1,165个位点。经过筛选，确保超过70%的类群在每个位点都有序列。通过对数据进行分析，我们重建了一个基于通过靶基因富集获得的数千个核编码序列的稳健的鲱形目系统发育树，这些序列经过精心挑选，以增强系统发育信息。我们证实了鲱形目的单系性，并确定齿头鲈是鲱形亚目的姐妹群。根据新的化石数据和更新的鲱形目分类，我们校正了鲱形目的时间树，并提供了新的分类系统。
