A.unicolor?

I found a few trapdoor spiders in Pennsylvania, and I believe they are A.unicolor. Is this correct? Thanks!
Thanks, there is a park that I can walk to in 10 minutes, and there are tons there. Also, what does the CF stand for?

CF. is used to label a specimen that is strongly believed to be and highly likely something, but isn't officially confirmed to be just yet. We use it alot in Australia due to the huge numbers of undescribed species we have. Recently we had a big discussion about the labelling of a supposed Teyloides bakeri and ended up using CF. bakeri to solve the dispute

[edit]
It can also stand for "colour form" in some cases but usually the former. Can't remember what words the letters themselves stand for
 
It might be Antrodiaetus unicolor, or it might not be. The picture doesn't provide enough information to make a determination of what it is. One must be careful using pictures found on the internet to identify mygales. Many of the American mygales look the same superficially and have a wide range across the country.

If it is important to get an accurate ID, then I can help. The catch is that I will need a specimen collected from the same site the one pictured comes from, dead or alive, in order to compare the characteristics of its body using a microscope with an identification guide. If you would like to try for yourself, then I recommend the book "Spiders of North America: An Identificatioon Manual, 2nd Edition" published by the American Arachnology Association (www.americanarachnology.org). It is the book I use to make accurate identifications to genus level of the spiders I find.

“cf.” in biology terms means closest fit, or confer, "compare with" in latin.

The reason I think it is A.unicolor is because it is the only species of trapdoor spider found in my area (southwestern Pennsylvania). Please correct me if I am wrong though.
