I strongly suspect this is in fact Theridiidae, maybe Dipoena in the broad sense.

I agree on Theridiidae, but i dont think this is a Dipoena s.l.
it might be a male juvenile Pholcomma gibbum, since there appears to be a dorsal scutum present on the abdomen, but i am far from 100% sure on that. Best to keep it as Theridiidae sp.

Dipoena has much smaller palp tibiae, as far as I can see.
Groeten, Weia

Right, now I see the granulose surface and I would agree.

This is a subadult, tibiae are swollen in subadults.

Thanks, I'll keep searching for an adult Pholcomma gibbum in our forest garden during the coming season to confirm your ideas.
