I thought I would ask for confirmation, or atleast more information about how to separate Hedychridium chloropygum from H. roseum.
I have never collected or seen this species before, but I'm quite sure this is a male Hedychridium chloropygum, from the colouration (the head and mesosoma is more vividly coloured in reality then on the pictures), puncturation of T2 and the fact that I collected it on the same spot as the host, Astata minor, both rare (or atleast uncommon) species in Sweden.
