利用遗传学、形态学和地理学的证据,我们研究了从美国西南部到哥斯达黎加分布的一支蚂蚁--细长假眼蚁群的种级分类和进化史。通过对2,524个UCE(超冷藏元素)基因座的定向浓缩,我们生成了一个系统发育数据集,并阐明了这些蚂蚁的系统发育关系和生物地理历史。据估计,该冠群起源于约8 Ma,在墨西哥和/或中美洲北部,随后扩展到中美洲南部和新北区西南部。塞普。细长石龙组包含低海拔和高海拔物种的混合体,显然在这些生境类型之间有多次过渡。我们发现了三个一个物种--有限的或边缘的地理分布--在系统发育上嵌入另一个物种的例子,使后者变得形影不离。其中一个病例涉及一种明显的无工作人员的社会寄生虫,它与其亲本物种共生,后者是宿主。这表明寄生虫物种在其宿主的分布范围内是同域起源的。用三种分子定界方法(SODA、BPTP、BPP)测试物种边界,但这些方法产生夸大的物种估计(26-46个物种),显然是因为未能区分种群结构和物种差异。在一份正式的分类修订本中。根据来自大约625个地点的近3,000个标本,我们考虑到物种内的地理差异,并使用共性中的区分性标准来检验关于物种限制的假设。在这些指导方针下,我们识别了13种,其中9种为新种:P.arcanus,sp.Nov.(墨西哥西部);Nov.(墨西哥西部);Nov.(墨西哥恰帕斯至尼加拉瓜);Nov.(墨西哥恰帕斯);Nov.(Veracruz,墨西哥);Nov.(墨西哥东南部,洪都拉斯);Nov.(墨西哥恰帕斯至哥斯达黎加);Nov.(哥斯达黎加);和P.Veracruzens,sp.11月(墨西哥韦拉克鲁斯)。我们的研究强调了结合系统基因组、表型和地理数据来解决分类学和进化问题的价值。
Using genetic, morphological, and geographical evidence, we investigate the species-level taxonomy and evolutionary history of thePseudomyrmex elongatulusgroup, a clade of ants distributed from southwestern United States to Costa Rica. Through targeted enrichment of 2,524 UCE (ultraconserved element) loci we generate a phylogenomic data set and clarify the phylogenetic relationships and biogeographic history of these ants. The crown group is estimated to have originated ~8 Ma, in Mexico and/or northern Central America, and subsequently expanded into southern Central America and the southwestern Nearctic. TheP. elongatulusgroup contains a mix of low- and high-elevation species, and there were apparently multiple transitions between these habitat types. We uncover three examples of one species—of restricted or marginal geographical distribution—being embedded phylogenetically in another species, rendering the latter paraphyletic. One of these cases involves an apparent workerless social parasite that occurs sympatrically with its parent species, with the latter serving as host. This suggests a sympatric origin of the parasite species within the distribution range of its host. Species boundaries are tested using three molecular delimitation approaches (SODA, bPTP, BPP) but these methods generate inflated species estimates (26–46 species), evidently because of a failure to distinguish population structure from species differences. In a formal taxonomic revision of theP. elongatulusgroup, based on almost 3,000 specimens from ~625 localities, we allow for geographic variation within species and we employ distinctness-in-sympatry criteria for testing hypotheses about species limits. Under these guidelines we recognize 13 species, of which nine are new:P. arcanus,sp. nov.(western Mexico);P. capillatus,sp. nov.(western Mexico);P. cognatus,sp. nov.(Chiapas, Mexico to Nicaragua);P. comitator,sp. nov.(Chiapas, Mexico);P. ereptor,sp. nov.(Veracruz, Mexico);P. exoratus,sp. nov.(southeastern Mexico, Honduras);P. fasciatus,sp. nov.(Chiapas, Mexico to Costa Rica);P. nimbus,sp. nov.(Costa Rica); andP. veracruzensis,sp. nov.(Veracruz, Mexico). Our study highlights the value of combining phylogenomic, phenotypic, and geographical data to resolve taxonomic and evolutionary questions.
