Hello,

I captured this specimen on September 01, 2020 at the level of a wetland (marsh) in the North of France. According to the key of robberblies.info I arrive at the genus Tolmerus. With the ovipositor of this form I think of Tolmerus strandi. But the species is not present neither in France nor in Belgium. Any idea?
