类似于 Camponotus maculatus (Fabricius, 1782) 的蚂蚁提供了一个机会来检验太平洋岛屿动物群起源主要是新几内亚、菲律宾和印度-马来群岛（统称为马来西亚）的假设。我们对来自太平洋岛屿、澳大利亚和马来西亚的 146 个样本的两个线粒体标记和四个核标记进行了测序。我们还添加了代表更大全球样本的 211 个标本，并进行了一系列系统发育分析和祖先区域重建。结果表明，该群体的太平洋成员由几个具有明显不同的生物地理历史的强大分支组成，这表明澳大利亚作为太平洋殖民来源地发挥着重要作用。马来地区主要在派生位置恢复，其中一个谱系似乎是新热带地区。系统发育假说表明，通常被鉴定为 C. Chloroticus Emery 1897 的橙色泛太平洋形式实际上由两个关系较远的谱系组成。此外，夏威夷的谱系被称为 C.variegatus（Smith，1858 年），似乎与佛罗里达州的 C.tortuganus Emery（1895 年）和新世界的其他谱系密切相关。在密克罗尼西亚和波利尼西亚，类似绿藻的物种支持分类单元循环假说的预测，并且可能是人类介导的扩散的候选者。 (C) 威利亨尼格协会 2014 年。
Ants that resemble Camponotus maculatus (Fabricius, 1782) present an opportunity to test the hypothesis that the origin of the Pacific island fauna was primarily New Guinea, the Philippines, and the Indo-Malay archipelago (collectively known as Malesia). We sequenced two mitochondrial and four nuclear markers from 146 specimens from Pacific islands, Australia, and Malesia. We also added 211 specimens representing a larger worldwide sample and performed a series of phylogenetic analyses and ancestral area reconstructions. Results indicate that the Pacific members of this group comprise several robust clades that have distinctly different biogeographical histories, and they suggest an important role for Australia as a source of Pacific colonizations. Malesian areas were recovered mostly in derived positions, and one lineage appears to be Neotropical. Phylogenetic hypotheses indicate that the orange, pan-Pacific form commonly identified as C.chloroticus Emery 1897 actually consists of two distantly related lineages. Also, the lineage on Hawai?i, which has been called C.variegatus (Smith, 1858), appears to be closely related to C.tortuganus Emery, 1895 in Florida and other lineages in the New World. In Micronesia and Polynesia the C.chloroticus-like species support predictions of the taxon-cycle hypothesis and could be candidates for human-mediated dispersal. (C) The Willi Hennig Society 2014.
