In your map, let $is_spider be empty if is not a spider ("default",
presumably), and be something else if it is a spider (possibly
$binary_remote_addr if every client should be counted individually,
or something else if you want to group some spiders together.)

Then define

  limit_req_zone $is_spider zone=slow:10m ...;

instead of what you currently have.
