I think I recall seeing something similar in the guide once upon a time but I can't remember where. I think this is an orb weaver of some sort, but quite unsure. Do adults come this small or is this an immature? I found this crawling along in my lawn and moved it to the concrete to take pictures so as not to lose it in the grass. These are all the pics I was able to get before it got away in the lawn again. Please feel free to frass.
