Monomorium Mayr是一种奇特的，世界性的蚁属，具有挑战性的系统历史，包括许多谱系，其关系是有问题的。这项研究采用了广泛的采样，主要是澳大利亚的分类群，沿着与其他属的Solenopsidini的范例，研究大陆的Monomorium动物群之间的关系。使用贝叶斯和最大似然法分析了延伸因子1 α F2、无翅和细胞色素氧化酶亚基1（COI）的序列。由此产生的进化树将澳大利亚的Monomorium分解为两个主要的分支，由来自其他属的样本分开;一个主要由具有11节触角的物种组成（对应于Monomorium s。str.在最近的一项研究Myrmicinae）沿着与三个古热带种。第二个分支包括有12节触角的澳大利亚物种，两个新西兰物种和两个来自新喀里多尼亚。两个澳大利亚隐生物物种被解析为进化枝2的姐妹。COI分析表明，部分物种（M. fieldi Forel，M.离开迈尔和M。Leae Forel）可能代表了隐种复合体。新西兰M。antipodum Forel被恢复为有效种，与澳大利亚东部种群密切相关。我们复活属Chelaner金刚砂的物种在第二支（与12节触角）和轮廓形态特征，以区分Chelaner从Monomorium s。53种Chelaner被视为任一统计。nov.或stat.

Monomorium Mayr is a speciose, cosmopolitan genus of myrmicine ants that has had a challenging systematic history, comprising numerous lineages whose relationships are problematic. This study employed an extensive sampling of mostly Australian taxa, along with exemplars of other genera of Solenopsidini, to examine relationships among the continent's Monomorium fauna. Sequences from elongation factor 1 alpha F2, wingless and cytochrome oxidase subunit 1 (COI) were analysed using Bayesian and maximum likelihood methods. The resultant phylogeny resolved Australian Monomorium into two major clades separated by exemplars from other genera; one comprised predominantly species with 11-segmented antennae (corresponding to Monomorium s. str. in a recent study of Myrmicinae) along with three Paleotropical species. The second clade included Australian species with 12-segmented antennae, two New Zealand species and two from New Caledonia. Two Australian cryptobiotic species were resolved as sister to Clade 2. COI analysis indicated that some species (M. fieldi Forel, M. leave Mayr and M. leae Forel) possibly represent cryptic species complexes. The New Zealand M. antipodum Forel was recovered as a valid species, and is closely related to an eastern Australian population. We resurrect the genus Chelaner Emery for species in the second clade (with 12-segmented antennae) and outline morphological characters to separate Chelaner from Monomorium s. str. Fifty-three species of Chelaner are treated as either stat. nov. or stat. rev.
