Tigrosa grandis

Hi Laura,
No apologies needed. :)

Why was it moved to Tigrosa grandis?

The help I receive on BugGuide always makes my day! :)

Hi, your spider closely resembles

those in the genus Tigrosa and given the range this is more likely Tigrosa grandis than other species in that genus. The light patches on the cheeks fit well with the illustration for T. grandis in Brady's 2012 description of the genus. She looks very similar to spiders another member (Chao "Jimmy" Wu) has been finding in Kansas that we also think are T. grandis. It's not an ideal image but he did manage to get a picture of the epigynum, what is visible in the image also seems to be consistent with diagrams for the species.

See how similar Tigrosa aspersa appears but lacks the yellow patches on the face:

There are also differences in how the ventrals appear with T. aspersa having a bolder arrangement of spots that converge into a median black line. At this time I'm unaware of anything else these could be.

Moved

Moved from Tigrosa.
Sorry about all the picture moving. I'm trying to get these sorted out. :)

Moved

Moved from Wolf Spiders.
Some species of Hogna were moved to a new genus, Tigrosa.

Wolf Spider

Thanks for the i.d.! and for the advice to photograph the ventral. as it was, i had chilled her for half an hour and it slowed her down for about five seconds.
as for the measurements, i don't think it will come as a shock that i am not Mrs. Arithmatic. :) Here are the real measurements provided by my husband who knows how to read a ruler. And I couldn't find one with mm. sorry.
The whole body is 12/16ths. The cephalothorax is 5/16ths. Does that make more sense????

… S. Carter, 24 June, 2012 - 8:58pm

Sure

12/16ths is 19 mm. That's pretty big, so something in the genus Hogna is likely. You can usually get a ventral shot pretty easily if you seal the spider in a plastic baggie then just turn the spider over. Just keep the camera at an angle so the flash doesn't reflect off the plastic.

Moved from ID Request.

This is a wolf spider. I'd guess it's a Hogna species which get pretty large. If you could measure the spider with a ruler in mm that would be helpful. Also a ventral view is helpful with this genus.

Please check

your measurements. The cephalothorax cannot be longer than the whole body. My best guess is a Fishing/Nursery Web Spider but I am far from an expert.
