Diaea ambara-flower spider

After consulting my spider book this is what I think this little 4mm spider is.
The colouration on the back helps it blend it well in the garden as it ambushes insects. It appeared on the washing trolley when I was hanging out the clothes.When I ran inside yelling spider Trev thought I needed a fly swat or the fly spray but I was after the macro lens.
Certainly the best arachnid I have ever managed.
An extra to show a side view.
Please correct me if I am wrong.
