Please help to identify the wasp in the enclosed picture. My rough guess is that it can be one of the following Pseudomalus violaceus or Hedychrum chalybaeum or Omalus aeneus (or perhaps something else).
More pictures of this specific insect can be found on my website: http://www.gardensafari.net/en_picpages/pseudomalus_violaceus.htm
Thank you beforehand for your help!
