The photomontage is of what appears to be a major worker from Niger, Niamey Airport, 13°28'38"N 02°10'31"E, elev 227 m; 20.viii.2006; David King. Two individuals sighted, one captured; foraging during the day.

This shows the slender form, quite bright red head and appendages, plus a black gaster. The clypeus is quite distinct from that of sericeus, in having no median carina but with the anterior margin with the median part concave and quite prominent denticles between the median arc and the lateral arcuate sectors. The forward pointing hairs on the clypeus margin are noticeably finer than on sericeus
