Ahh the starter motor heatshield!! It is on there, you just can't see it from that pic. I've also got a nimbus manifold heatshield to protect the brake pipes.
There's a funny story to the starter heatshield though. A few months ago when i first took the starter off as I thought it had packed up, (it actually turned out to be the big fuse to the +ve which i'd totally forgotten to check) I found the starter heatshield on the wrong side of the starter! Not naming any names, but the previous owner must have put the heat shield on between the block and the starter, so it wasn't providing any protection to heat from the manifold Hehe.
I sorted that a while back though.
