Yes, it is a male Macquartia, though the vertex is a bit broad.
It would key out to M. chalconota, a rare species.
i need to check my collection.

OK, we need to take a deep breath.
The broad vertex (for a male Macquartia), the very short antenna and numerous discal bristles would indicate M. hystrix, a strictly alpine species.
Now, the Ardennes are hilly, but alpine is a bit steep.
Without specimen and possibility to check the genitalia, I am for obvious reasons reluctant to make this call. There might be something else going on, it could be an intersex (rare, but less rare than you think !).
I notice the record is from 2010, but Christine, if you ever have an opportunity to collect one, please do ! If correct, it would be a most amazing find.
