Red-thigh Chalcid Wasp

Animal is small. About 4mm. Found in our garden near peas and rasberry. Very mobile. It showed a explosive flight response similar to a few Long Legged Flies. Just when I thought I had the perfect frame. The identification is speculative. It is very similar but different to Tetragonia carbonaria, formerly Trigona carbonaria which is also called Carbonaria Stingless Bee or Sugarbag Bee. I doubt that it is the same species as what I present as Sugarbag Bee on my website. However, we have some callistemon flowering at the moment which used to be attracting this bee. You can clearly see three oculi on top of head. Antennae are not bent though. Wings attached at the front thorax, covering but not hiding the second segment of it. There. The colourful, extremely long hind legs were inspiring my choice of made-up name. ALA can not be used at the moment and there are hardly any photo documentations on the web. Update 20/10/2016: So great to get some feedback from Deb Yarrow pointing out that this is rather a Chalcid wasp. I had come across a picture of a similar looking wasp when hunting for a different identification. This species is being renamed from Red-thigh Stingless Bee into Red-thigh Chalcid Wasp.
