Sesiidae, and what a species!!
Not seen anything like this before, though it is a clear mimic of a spider hunting wasp (Sphecidae?) that is quite common locally.
I have no idea on even the genus for this one, will take me a while (probably) to trace it.
back sometime later once I've a moment to do a bit of research.
