Indeed very very nice pictures.

Assuming you made these pictures near Berlin, Pterella would be a very nice finding.

But I do not agree on Pterella for several reasons.
The male has rather big claws.
On vertex I do not see any hairs next to the bristles.
On notopleuron I do not see any hairs next to the notopleural bristles.
Tegula seems to be black.
Basic colour of frontal stripe should be yellow in Pterella but is black.

Therefore I think this is a couple of Senotainia albifrons.

Btw: Frons is indeed in male often broader than in female in Pterella as well as in Senotainia.
