We examined the above two males from central Africa but are unable to match them to their respective females. They differ markedly from the associated females collected in the same rainforest localities in Central African Republic and Uganda, particularly with respect to presence or absence of banding on the antennae, and relative size of the propodeal apophyses, for both of which they are more typical of the South African species associated with arid habitats. There is clearly sexual dimorphism present in the genus exacerbating reliable matching of the sexes and a barcoding analysis will be required to facilitate resolving conspecifics across the sexes in this genus.
