An update to the taxonomy and distribution of the Arabian Tapinoma Foerster, 1850 (Hymenoptera: Formicidae) with an illustrated key and remarks on habitats.

Ants of the genus Tapinoma of the Arabian Peninsula are reviewed, keyed and illustrated, based on the worker caste. Three species are diagnosed, T. melanocephalum (Fabricius, 1793), T. simrothi Krausse, 1911 and T. wilsoni Sharaf & Aldawood, 2012. We present the first illustrated key to the Arabian Tapinoma, enhanced by automontage images to facilitate species recognition. New distributional data for species are presented, based on recently-collected material from the region and literature records. Information on habitats' preference and biology of species are given.
