Found one image from that book on a friends page.

Not a common spider, but a Mygalomorph, or tarantula/birdeating spider/Earthtiger or whatever local name that are used.
If you are a beginner, a more bulkier spider would be easier to model.
Edit: bout the 7 segments, some say that there are 6, but other count for the first part where the leg meats the body, not seeable on this image.
