Mimumesa sp of wasp (Garden)

A small, black sphecid wasp, formerly placed within the genus Psen. It is one of ten species currently placed within the genus Mimumesa to be found in Europe.

There isn’t much information on this genus of wasp, I tried to find out what type of wasp it was by using the Wing cells/veins and the solitary wasp field guide and got it to Psen , wrong now of course but after speaking to a friend he showed me where i had gone wrong … its al a learning curve
