, with distinguishing characters given in the remarks section of the latter species. Among these, the most important are the flat eyes in mamba that do not reach the lateral cephalic outline in full face view. Also, the striae on the vertex in mamba are tranversely bowed, while they are longitudinal in kokoda. One dealate queen was collected foraging with workers on the trunks and branches of freshly felled trees on the edge of a recent rainforest clearing. The second queen was collected with a kokoda worker at Oivi Ridge nr Kokoda.
