Ecological and biological notes

This species nests in soil under stones or in leaf litter ( Bolton 1980). It is abundant in areas where Vachellia and Calotropis procera (Aiton) W.T.Aiton ( Apocynaceae Juss. ) plants occur (Sharaf et al. 2013). Workers are predators on other ants ( Lévieux 1972). This species is basically found wherever it is comparatively hot and there is sandy soil and no closed canopy ( Bolton 1980). This explains the broad geographic distribution in the vast areas of the Arabian deserts.

Geographic range

Originally described from Eritrea, it is known from the Afrotropical, the Malagasy, and the Southern Palaearctic Regions ( Hita Garcia & Fisher 2011). Sharaf et al. (2013) pointed out the remarkable wide geographic distribution of this species in the Arabian Peninsula, as previously mentioned by Collingwood (1985), Collingwood & Agosti (1996), and Collingwood et al. (2011). This species is recorded for the first time in Dhofar.
