摘要揭示外异形蚁亚科和异蚁亚科的进化历史是理解蚂蚁生命树主要分支的关键。尽管它们的多样性和生态重要性，在组中的系统发育关系还没有得到很好的探讨。一个特别合适的工具，解决遗传是使用超保守元件（UCE），已被证明是理想的标记在各种进化的时间尺度。在本研究中，我们富集并测序了2，从135个外异型蚂蚁标本中提取了127个UCE，并使用各种基于模型的基因组学方法研究了后代发生。树分析结果很好地解决了大部分的一致性。2结果与扩展后的外囊蜂亚科概念一致，该亚科现在包括了异囊蜂亚科的新异名和它的单一族异松叶蜂属新组合。11个单系群被确认为属：新的系统发育框架和新的分类将有助于外齿螨亚科的分类和系统学研究，并有助于对外齿螨亚科的分类和系统学研究。以及它所包含的群体的形态演变。
Abstract Uncovering the evolutionary history of the subfamilies Ectatomminae and Heteroponerinae, or ectaheteromorphs, is key to understanding a major branch of the ant tree of life. Despite their diversity and ecological importance, phylogenetic relationships in the group have not been well explored. One particularly suitable tool for resolving phylogeny is the use of ultraconserved elements (UCEs), which have been shown to be ideal markers at a variety of evolutionary time scales. In the present study, we enriched and sequenced 2,127 UCEs from 135 specimens of ectaheteromorph ants and investigated phylogeny using a variety of model-based phylogenomic methods.Trees recovered from partitioned maximum-likelihood and species-tree analyses were well resolved and largely congruent.The results are consistent with an expanded concept of Ectatomminae that now includes the subfamily Heteroponerinae new synonym and its single tribe Heteroponerini new combination. Eleven monophyletic groups are recognized as genera: Acanthoponera, Alfaria status revived, Boltonia Camacho and Feitosa new genus, Ectatomma, Gnamptogenys, Heteroponera, Holcoponera status revived, Poneracantha status revived, Rhytidoponera, Stictoponera status revived, and Typhlomyrmex.The new phylogenetic framework and classification proposed here will shed light on the study of Ectatomminae taxonomy and systematics, as well as on the morphological evolution of the groups that it comprises.
