斑潜蝇属(双翅目：斑潜蝇科)是一种广泛分布于全球的有翅类蝇类。美洲斑潜蝇属物种之间的系统发育关系一直没有得到完全的研究，也从未利用分子数据进行过充分的研究。在这里，我们使用各种系统发育方法(最大似然、贝叶斯推断和基因树合并)在锚定杂交浓缩(AHE)获得的基于目标捕获的系统发育数据集(核苷酸和氨基酸)上重建美洲斑潜蝇属的系统发育。我们已经恢复了在所有数据类型和方法中几乎一致的树拓扑，并且在所有系统发育分析中都有强大的个体分支支持。此外，明确的形态物种群和分支在我们对分子系统发育的最佳估计中得到了很好的支持。美洲斑潜蝇[L.huidobrensis(Blanchard)，L.Langei Frick，L.bryoniae]是已知的杂食性蔬菜害虫[L.huidobrensis(Blanchard)，L.Langei Frick，L.bryoniae]的姐妹群。(Kaltenbach)、三叶乳杆菌(L.trifolii(Burgess))、三叶乳杆菌(L.sativae Blanchard)和甘蓝乳杆菌(L.brassicae(Riley))。属于树上亲缘关系不是特别密切的多个支系。通常，近缘美洲斑潜蝇以远亲寄主植物为食。我们拒绝认为美洲斑潜蝇与其寄主植物之间的共生发育过程推动了该属的多样性。相反，美洲斑潜蝇表现出一种广泛的寄主跨植物类群转移的模式。我们对斑潜蝇的新的系统发育估计为该属寄主利用模式的进化提供了相当多的新信息。此外，它还为进一步研究这些重要苍蝇的形态、生态学和多样性提供了一个框架。
The genus Liriomyza Mik (Diptera: Agromyzidae) is a diverse and globally distributed group of acalyptrate flies. Phylogenetic relationships among Liriomyza species have remained incompletely investigated and have never been fully addressed using molecular data. Here, we reconstruct the phylogeny of the genus Liriomyza using various phylogenetic methods (maximum likelihood, Bayesian inference, and gene tree coalescence) on target‐capture‐based phylogenomic datasets (nucleotides and amino acids) obtained from anchored hybrid enrichment (AHE). We have recovered tree topologies that are nearly congruent across all data types and methods, and individual clade support is strong across all phylogenetic analyses. Moreover, defined morphological species groups and clades are well‐supported in our best estimates of the molecular phylogeny. Liriomyza violivora (Spencer) is a sister group to all remaining sampled Liriomyza species, and the well‐known polyphagous vegetable pests [L. huidobrensis (Blanchard), L. langei Frick, L. bryoniae. (Kaltenbach), L. trifolii (Burgess), L. sativae Blanchard, and L. brassicae (Riley)]. belong to multiple clades that are not particularly closely related on the trees. Often, closely related Liriomyza species feed on distantly related host plants. We reject the hypothesis that cophylogenetic processes between Liriomyza species and their host plants drive diversification in this genus. Instead, Liriomyza exhibits a widespread pattern of major host shifts across plant taxa. Our new phylogenetic estimate for Liriomyza species provides considerable new information on the evolution of host‐use patterns in this genus. In addition, it provides a framework for further study of the morphology, ecology, and diversification of these important flies.
