Nice pictures!
Its a Hedychrum sp., malei, ts either H. nobile or H. niemelai, although the size makes the latter more probable. Potentially it could also be H. gerstaeckeri but the punctures on tergite 3 seem far too fine for that species.
They cant really be told apart from pictures like these, need to see the small pit/depression on the inner side of the middle tibia to get a reliable ID, which is very hard to photograph adequately on living animals.
