Comments & ID Thoughts
This is a female wolf spider carrying its egg sac in its spinnerets. It was taken at MacGregor Point Provincial Park on the forest floor at 12:30 pm. There will be 4 more pictures of the same individual from different angles.
Any help getting it down to genus or further would be appreciated.

Hi, welcome to SpiderID. 🙂 Your spider is a Tigrosa helluo.
Thanks ItsyBitsy. For my own education I looked more closely at Tigrosa and see that there are only 5 species in this genus north of Mexico and only 2 that have been recorded in Ontario – T. aspersa and T. helluo. As I only have dorsal views of this spider it seems to me the best way to distinguish between the 2 is by looking at the median stripe on the carapace. On T. aspersa the stripe is supposed to be restricted to the eye region only (or at least be the most visible there) whereas the stripe on T.… Read more »
Also in addition to my other comments below it looks like T. aspersa would have strongly banded legs unlike the solid leg colour of T. helluo….
Yes, T. aspersa tends to have more striking coloration on the leg bands and carapace stripe. The females can be black with rich yellow accents (the males are straw colored), or at least a darker brown with a more contrasting yellow. T. helluo leans towards being more average brown or sometimes a drab nearly olive brown color with weak or no visible banding on the legs.
