摘要Rasopone Schmidt和Shattuck是生活在新热带森林中的一个鲜为人知的蚂蚁谱系。根据数千个超保护元素(UCES)和线粒体DNA条形码的系统发育结果，我们对该属进行了修订，提供了新的形态诊断和物种水平的治疗。对许多Rasopone样品和部分外群的UCE数据进行分析，发现该属的非单系性。通过将几个种转移到不相关的Mayaponera、Schmidt和Shattuck属，恢复了Rasopone的单叶性。在Rasopone内部，物种在形态上非常相似，我们提供了一种“鸟类指南”方法来识别，而不是传统的二分法。物种在表格中按大小排列，以及地理范围和标准图像。然后，在个别物种账户中提供额外的诊断信息。我们共识别了15个命名种，其中包括被描述为新种的新种：R.costaricensis、R.cryptergate、R.cubitalis、R.guatealensis、R.Mesoamericana、R.storviselva、R.politognatha、R.subcubitaris和R.titiis。另有12个形态种被描述，但由于材料不足而未正式命名。Rasopone panamensis(Forel，1899)被从异名中删除并提升到种。以下种被从Rasopone中移除并在Mayaponera中进行新组合：M.arhuaca(Forel，1901)、M.becculata(Mackay和Mackay，2010)、M.cernua(Mackay和Mackay，2010)、M.conrula(Mackay和Mackay，2010)、M.Longidentata(Mackay和Mackay，2010)和M.pergandei(Forel，1909)。
Abstract Rasopone Schmidt and Shattuck is a poorly known lineage of ants that live in Neotropical forests. Informed by phylogenetic results from thousands of ultraconserved elements (UCEs) and mitochondrial DNA barcodes, we revise the genus, providing a new morphological diagnosis and a species-level treatment. Analysis of UCE data from many Rasopone samples and select outgroups revealed non-monophyly of the genus. Monophyly of Rasopone was restored by transferring several species to the unrelated genus Mayaponera Schmidt and Shattuck. Within Rasopone, species are morphologically very similar, and we provide a ‘bird guide’ approach to identification rather than the traditional dichotomous key. Species are arranged by size in a table, along with geographic range and standard images. Additional diagnostic information is then provided in individual species accounts. We recognize a total of 15 named species, of which the following are described as new species: R. costaricensis, R. cryptergates, R. cubitalis, R. guatemalensis, R. mesoamericana, R. pluviselva, R. politognatha, R. subcubitalis, and R. titanis. An additional 12 morphospecies are described but not formally named due to insufficient material. Rasopone panamensis (Forel, 1899) is removed from synonymy and elevated to species. The following species are removed from Rasopone and made new combinations in Mayaponera: M. arhuaca (Forel, 1901), M. becculata (Mackay and Mackay, 2010), M. cernua (Mackay and Mackay, 2010), M. conicula (Mackay and Mackay, 2010), M. longidentata (Mackay and Mackay, 2010), and M. pergandei (Forel, 1909).
