Ecological and biological notes

This species was observed ascending the trunk of a tree of Vachellia Wight & Arn. (Fabaceae) .

Geographic range

This species was described from Ethiopia and has been recorded from Eritrea and Sudan (AntWeb 2022). Although our collected major worker is ~20% larger, and perhaps darker, than the type major worker, the identification seems secure. This species is a new record for Dhofar and Oman.
