Remarks: This ponerine ant is widely distributed throughout sub-Saharan Africa, where it inhabits savannas and open forests; it is also the most common member of the subfamily in southern Arabia. While it is regarded as native at least throughout Africa, it is also notably preferring man-impacted habitats, such as human settlements, rubbish dumps and waste ground. Thus it is in question whether the species is indigenous to the Socotra Archipelago. It is a general scavenger but will attack other insects and has a painful sting. Allergic reactions to the sting, sometimes severe, are a problem locally in Arabia (Dib 1992, Rizk et al. 1998), where it is called the "Samsun ant". Probably because of awareness of the painful sting, Socotri people refer to this ant by a specific denomination ( “dfftim”), as different to the word for ant ( “nimihil”).
