The taxonomy of the dolichoderine ants of the genus Technomyrmex Mayr, 1872 is revised for the Arabian Peninsula. Six species are treated, T. albipes (F. Smith, 1861), T. difficilis Forel, 1892, T. briani Sharaf, 2009, T. vexatus (Santschi, 1919), T. montaseri Sharaf, Collingwood & Aldawood, 2011, and T. setosus Collingwood, 1985. The successful tramp species T. difficilis Forel, 1892 is recorded for the first time from the Kingdom of Saudi Arabia (KSA) and Yemen, representing new records for the Palearctic Region. Technomyrmex vexatus (Santschi, 1919) is a new species record for Yemen. The queen caste of the rare endemic species, T. briani Sharaf, 2009 is described for the first time. A neotype for KSA endemic T. setosus Collingwood 1985 is designated based on a specimen collected from the type locality, the Asir Mountains, KSA, including new information on habitats and distribution. A male cast of Technomyrmex, possibly of T. setosus, is also described. An illustrated key based on the worker caste of the Arabian species of Technomyrmex is given. New geographical records and a distribution map for the treated species are presented.
