    X-Ray microtomography for ant taxonomy: An exploration and case study with two new Terataner (Hymenoptera, Formicidae, Myrmicinae) species from Madagascar
    (Public Library of Science, 2017) Hita Garcia, Francisco; Fischer, Georg; Liu, Cong; Audisio, Tracy L.; Alpert, Gary; Fisher, Brian L.; Economo, Evan P.
    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. and T. nymeria sp. n.. We provide an illustrated worker-based species identification key for all species found on Madagascar, as well as detailed taxonomic descriptions, which include diagnoses, discussions, measurements, natural history data, high-quality montage images and distribution maps for both new species. In addition to conventional morphological examination, we have used virtual reconstructions based on volumetric μCT scanning data for the species descriptions. We also include 3D PDFs, still images of virtual reconstructions, and 3D rotation videos for both holotype workers and one paratype queen. The complete μCT datasets have been made available online (Dryad, https://datadryad.org) and represent the first cybertypes in ants (and insects). We discuss the potential of μCT scanning and critically assess the usefulness of cybertypes for ant taxonomy.

    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
    (Pensoft Publishers, 2014) Hita Garcia, Francisco; Hawkes, Peter G.; Alpert, Gary
    Abstract 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 (Proceratium arnoldi, Proceratium stictum and Proceratium toschii clades) and revise the Proceratium arnoldi clade. Four new species from the Proceratium arnoldi clade are described as new: Proceratium sokoke sp. n. from Kenya, Proceratium carri sp. n. from Mozambique, and Proceratium nilo sp. n. and Proceratium sali sp. n. from Tanzania. In order to integrate the new species into the existing taxonomic system we present an illustrated identification key to distinguish the seven Afrotropical species of the Proceratium arnoldi clade. In addition, we provide accounts for all members of the Proceratium arnoldi clade including detailed descriptions, diagnoses, taxonomic discussions, distribution data and high quality montage images.
