It is with considerable reluctance that I have confirmed this identity. Leioproctus amabilis is much more common and comes in a wide range of colours including greeny bronze. Females of L. amabilis, L. clarki and L. cupreus are separated by features that can't be seen in photos. On balance, I would think that this is a little more likely to be clarki than amabilis, with the proviso that the colour of the abdomen is not definitive.
Thanks Michael, I thought it looked more like existing images of L. clarki, but I’m aware these online IDs can be self referencing and end up reinforcing errors. That said an expert can sometimes also just “see” a difference that can’t be (or hasn’t been ) used in key - a bit like sexing chickens or a sophisticated AI algorithm - nobody knows how it works. I did see one reference to L. clarki having orange leg hair, which my specimen doesn’t but I wasn’t sure if that was definative
Glynn Maynard's key uses the colour of the leg hair to separate L. clarki ("whitish") from L. carinatus ("black"), but only after eliminating everything else using the shape of the pygidial plate. Male terminalia may be the only unambiguous way to separate some of these species.
