its a Holopyga, the sharp temples in the last image is rules out Hedychridiumand Hedychrum. No idea what species though, I find the genus hard to get a grip on
interesting finding. I'm not sure, but this could be the male of Holopyga merceti Kimsey or H. duplicata Linsenmaier. However, not even Linsenmaier (1997) was able to separate males of these two species.
