Hi D.!
The valid taxon is: caputaureum Trautmann (in Trautmann & Trautmann), 1919.
You can consider it as
- a valid species: Hedychridium caputaureum, following many German authors (i.e. Niehuis, 1998)
- subspecies of: H. roseum (Rossi), following Linsenmaier and Faunaeur
- subspecies of: H. chloropygum du Buysson, following Arens.
I let you decide which is the best combination.
My impression is that this taxon could be the central and Northern form of chloropygum, but it could be also considered as a form of roseum. I hope that in the next future molecular analysis will help in this troubles.
Cheers
Paolo
