on some South African specimens I could examine and which are very similar to some Somalian specimens at MSNM. All of them well fit Bolton’s description, except that the Somalian specimens are slightly smaller, have a lower SI, and lack proximal hairs on the clypeal dorsum (a few ones occur in South African specimens) and on tergites II-III. South African and Somalian specimens look inseparable on the basis of all main features: head shape, mesosomal shape and proportions, propodeal spines and ridge, petiolar structure, sculpturation, pubescence length and density, and I consider them as conspecific. The measurements below refer to Somalian specimens for comparison with South African ones already given by Bolton (1973) (n=3).
