I'm going to make you 2 proposals for this taxon! Look at Dyenmonus nuptus Thomson, described from the Cape territory. For me it is clearly not Dyenmonus (Vittatodyenmonus) nigrifrons Aurivillius even if there is a resemblance! On the other hand look at Dyenmonus (Vittatodyenmonus) trivittatus Aurivillius described from the southern DRC (ex Zaire) and I have seen an ex from Cameroon. This is what I can tell from this picture, tell me what you think about it ?
Hi Jérôme, Thanks for the help on this, from your two proposals above: I note that in D. trivittatus Auriv. the mesosternum is yellow, and the meta-sternum largely orange in the middle, where as the meso- and meta- sternum are black in D. nuptus Thomson.
