Wolf Spider Identification - Tigrosa georgicola - female

Wolf Spider Identification - Tigrosa georgicola - Female
Topeka, Shawnee County, Kansas, USA
June 24, 2013
Size: 1 inch body length.
Found her hiding under some vegetation. I have kept other species of wolf spiders before of the Hogna and Tigrosa genus. This individual is identified by me as a Tigrosa helluo or possibly another species of Tigrosa (Possibly Tigrosa georgicola). I didn't want to put her in a glass jar just to take a picture of her underside for she is carrying an eggsac. Please confirm/revoke my guess if possible. Thanks!

Image of Dorsal of Epigynum
Unfortunately, I've donated this specimen. However, I still have a single T. georgicola in alcohol for later use. I've posted this image of a dorsal of the molt of another individual's epigynum:

Moved to Tigrosa georgicola
Moved from Wolf Spiders. I think this is likely. However, I'd like to point out that the leg banding is light and that it appears to have 5 dark stripes on the venter instead of 3. Of course, there is almost always variation within a species, so I think that's what we're seeing here. Also, I wouldn't rule out the possibility of cross breeding either since I haven't studied these very much.

 
Range
Do T. georgicola normally make it this far into Kansas? This is my first year spotting this species so I'm still questioning the range. Within the T. georgicola page, it mentions how it is distributed within the Southeast.

 
Sort of
They are recorded from that far west and from farther north in the east. I think you're easily in its range. I'll list the states on the info page.

 
Thanks
Thanks for the quick reply...I guess I missed this species with the plagues of T. helluos in the area. Plus, T. georgicola is more restricted to grassy deciduous forest clearings unlike T. helluo. Helluo can be found almost everywhere there is suitable food and large patches of grass.

Moved
Moved from ID Request. Leg banding isn't quite as dark as I'm used to seeing. I'm going to move here for now.

 
I would say georgicola as well
the venter is right. the stripe on the carapace gradually narrows between the eyes. An examination of the epigynum is the only way to know for sure what species this is.

 
Leg banding
That was what drew me away from it being a T. georgicola. Is there a possibility for different hybridization within the genus? The area I found this individual is also home to T. helluo and H. caroliensis. Or is it just a slight coloration difference? Will update with ventral shot once she stops being defensive with her eggsac.

 
Ventral shot
would be awesome. I'm not sure about your other questions.

 
Update
Her young have hatched, should be two or three weeks before I will try and get the ventral. I do have a question though, do T. georgicola usually make it this far up into NE Kansas? I thought its population was more or less restricted to the southeast.

Tigrosa georgicola?
There is some banding on the legs and the carapace stripe is long, so I'd say T. georgicola. Nice one.

 
Difference?
Would you mind elaborating the main differences between T. helluo and T. georgicola?

 
...
For dorsal-only images, I've been going primarily by leg banding. When absent, I guess T. helluo. When present, either T. aspersa or T. georgicola depending on the carapace stripe. There are ventral differences as well, which the info pages for the species elaborate on. Some of our other members know these better than I do, maybe they can tell you more.
