蚁属NylanderiaEmery具有世界性分布，包括150个现存描述的物种和亚种，可能还有数百个未描述的物种。由于种内和种间形态变异强烈、诊断特征数量有限以及依赖不常收集的雄性标本进行物种描述和鉴定，全球分类学修订长期以来一直停滞不前。Nylanderiabe是全球入境口岸最常截获的蚂蚁属之一，分类学进一步复杂化，至少有15种环球旅行物种具有广泛和不断扩大的范围，使得物种水平的诊断变得困难。三个物种复合体（'bourboniccomplex'，'fulvaccomplex'和'guatemalensiscomplex'）包括环球旅行物种。为了阐明这三个复合物的系统发育位置，并划定物种边界内的每一个，我们使用了目标富集的ultraconserved元素（UCEs）从165个标本代表98Nylanderiamorphopropecies全球。我们还分阶段进行了UCE，有效地将样本量增加了一倍，并增加了人口水平的抽样。在恢复了对每个复合体的单系性的强有力支持后，我们从UCE数据中提取了COI条形码和SNP，并使用三种分子划界方法（SODA，bPTP和STACEY）测试了复合体内形态种假说。这种比较表明，大多数方法倾向于过度分裂类群，但从STACEY的结果是最符合我们的形态种假说。使用这些结果，我们建议物种边界是保守的，最一致的所有方法。这项工作强调了入侵物种管理的综合分类学的重要性，因为环球旅行独立地发生在至少九个不同的谱系acrosnylanderia。
The ant genusNylanderiaEmery has a cosmopolitan distribution and includes 150 extant described species and subspecies, with potentially hundreds more undescribed. Global taxonomic revision has long been stalled by strong intra- and interspecific morphological variation, limited numbers of diagnostic characters, and dependence on infrequently collected male specimens for species description and identification. Taxonomy is further complicated byNylanderiabeing one of the most frequently intercepted ant genera at ports of entry worldwide, and at least 15 globetrotting species have widespread and expanding ranges, making species-level diagnoses difficult. Three species complexes (‘bourbonicacomplex’, ‘fulvacomplex’, and ‘guatemalensiscomplex’) include globetrotting species. To elucidate the phylogenetic positions of these three complexes and delimit species boundaries within each, we used target enrichment of ultraconserved elements (UCEs) from 165 specimens representing 98Nylanderiamorphospecies worldwide. We also phased the UCEs, effectively doubling sample size and increasing population-level sampling. After recovering strong support for the monophyly of each complex, we extracted COI barcodes and SNPs from the UCE data and tested within-complex morphospecies hypotheses using three molecular delimitation methods (SODA, bPTP, and STACEY). This comparison revealed that most methods tended to over-split taxa, but results from STACEY were most consistent with our morphospecies hypotheses. Using these results, we recommend species boundaries that are conservative and most congruent across all methods. This work emphasizes the importance of integrative taxonomy for invasive species management, as globetrotting occurs independently across at least nine different lineages acrossNylanderia.
