Who knows?

"There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns – the ones we don't know we don't know."

This is a known unknown. I know it is Gelis spp. (thanks to Gavin Broad's help), but I don't know which species - they are one of the more difficult groups of Ichneumons.
