title: 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.
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 (Proceratiumarnoldi, Proceratiumstictum and Proceratiumtoschii clades) and revise the Proceratiumarnoldi clade. Four new species from the Proceratiumarnoldi clade are described as new: Proceratiumsokoke sp. n. from Kenya, Proceratiumcarri sp. n. from Mozambique, and Proceratiumnilo sp. n. and Proceratiumsali 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 Proceratiumarnoldi clade. In addition, we provide accounts for all members of the Proceratiumarnoldi clade including detailed descriptions, diagnoses, taxonomic discussions, distribution data and high quality montage images.
