X-Ray microtomography for ant taxonomy: An exploration and case study with two new Terataner (Hymenoptera, Formicidae, Myrmicinae) species from Madagascar.

We explore the potential of x-ray micro computed tomography (μCT) for the field of ant taxonomy by using it to enhance the descriptions of two remarkable new species of the ant genus Terataner: T. balrog sp. n.

The myrmicine ant genus Metapone Forel (Hymenoptera: Formicidae): a global taxonomic review with descriptions of twelve new species.

The 28 known species of Metapone are monographed and illustrated. Twelve are described as new: M. africana, Gabon; M.

Molecular phylogeny of Indo-Pacific carpenter ants (Hymenoptera: Formicidae, Camponotus) reveals waves of dispersal and colonization from diverse source areas.

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.

Taxonomy of the ant genus Proceratium Roger (Hymenoptera, Formicidae) in the Afrotropical region with a revision of the P.arnoldi clade and description of four new species.

The taxonomy of the genus Proceratium Roger is updated for the Afrotropical region. We give an overview of the genus in the region, provide an illustrated identification key to the three clades (Proceratiumarnoldi, Proceratiumstictum and Proceratiumtoschii clades) and revise the Proceratiumarnoldi clade. Four new species from the Proceratiumarnoldi clade are described as new: Proceratiumsokoke sp.

A new species of Tyrannomyrmex (Hymenoptera: Formicidae) from Sri Lanka.

Tyrannomyrmex legatus sp. nov. is described based on a single worker collected from leaf litter in dipterocarp forest in southern Sri Lanka.

A synoptic review of the ant genera (Hymenoptera, Formicidae) of the Philippines.

An overview of the history of myrmecology in the Philippine archipelago is presented. Keys are provided to the 11 ant subfamilies and the 92 ant genera known from the Philippines. Eleven ant genera (12%), including 3 undescribed genera, are recorded for the first time from the Philippines.

Gamergates in the myrmicine genus Metapone (Hymenoptera: Formicidae).

Gamergates (i.e. mated reproductive workers) are mostly known from ant species within the Ponerinae.
