This one is tougher. Would it be possible to take several more pics of this guy......from the side, wo glare, and even after mounting it?
The exposure in the pic hinders some details from showing. May be helpful to see the legs as well.

OK. I'll relax it and come back to this topic with new photos in a few days. Thank you for your help.

Looks like Rhyxiphloea corticina Burmeister.

I relaxed the specimen and took a few additional photos. I hope this can help a bit. This seems to be a female, so no aedeagus for comparison. Please have a look at three photos below. Do these confirm Rhyxiphloea corticina? Thank you beetlemanx for the ID. |

While I'm not sure, I would go with Rhyxiphloea corticina as well. The under part of the specimen throws me off personally.

NO. R. corticina has dense punctures on pronotum and elytra, more prominently raised costae, and a less marginated antescutellar margin. Also, R. corticina is more brilliant, and has long hair on meta-tarsi (very clear diagnostic character).
I'll try to identify your specimen later.
Cheers, M

Probably Heterotephraea marginata (Shurhoff), it resembles the HT. It could also be H. arborescens (Vigors). Both are from West Africa.
Note that yours is a melanic (rare) form, typically these beetles are yellow and black and resemble small Pachnoda. I assume the size is around 15-18 mm.
Also note that these species were previously assigned to Psacadoptera.
It is my best guess, but I'm not 100% sure.
Cheers, M

PS: I just found in my collection a single specimen of H. marginata that is identical to yours (also the underside, pilosity and marks on sternites). From Togo, Missahohe. Only one melanic specimen in a very long series of orange/back specimens.
So, I can now confirm it is H. marginata.
Best, M

Incredible! That was a great find based just on a photo! Thank you, depalma! I am sorry I could not find this myself. I have the normal morph of this species, but did not recognize the melanic form. The reason is probably that I am mainly focused on Cerambycidae, keep some A2 Cetoniinae specimens for reference, but sell others at ebay to release funds for longhorns. I am placing a collage of two specimens below just to show the difference between the two forms. Attachments:
