C35B7839F2D262ED82FE5A9B68A91580.taxon	distribution	Distribution. As already pointed out by Hita Garcia et al. (2017), this species has the widest distribution of any species of the N. angulatus group, and is certainly the most widespread Nesomyrmex species worldwide. Nesomyrmex angulatus has been reported from most African countries, as well as on the Arabian Peninsula and most of the Malagasy Region. The species seems to prefer comparatively arid environments and is predominantly found in cavities of dead wood, trunk of trees, lower vegetation and rarely on the ground (Bolton 1982; Mbanyana and Robertson 2008).	en	Sharaf, Mostafa R., Akbar, Shahid Ali, Aldawood, Abdulrahman S., Garcia, Francisco Hita (2017): Review of the ant genus Nesomyrmex Wheeler, 1910 (Hymenoptera, Formicidae, Myrmicinae) from the Arabian Peninsula.
