Nice ones, thanks for getting the ventral! There are a lot of FL Hognas we're not yet familiar with, hopefully we'll be able to figure these out soon. I heard rumors a revision of the genus was in the works, when that happens that might shed some light on some of these.

 
Can someone please put me in contact
With the people working on this family revision? Thank you!!!

 
Unfortunately I don't know...
who would be working on that. In 2012 some species were removed from Hogna and placed in a new genus Tigrosa, hopefully there's still some work being done on the genus. I shouldn't have mentioned it because I confused it with another genus I'd heard might be getting a revision and had found a page confirming who was doing that one few weeks ago, when I looked the page up again to see who it was I realized my error. If you want to preserve a mature one and send it out to be examined I can ask around as to who would be the best person to send it to.

 
No problem
Yea, I would love to get material to someone.

But please note. The images that I first posted of the Juno- Hogna- Like, and assumed these were juveniles of, are very different. The new animal I got tonight matches the former post, and is much more H. lenta-like, and much darker (tan, brown, white). You'll see in my post when I get to it tomorrow. Please do if you get any leads, I'd be very happy to provide material as I hunt snakes at night. Thank you Laura for you help!!!!

Best,
Kenny

Seems to fit
Arctosa descriptions in part?

 
Yes, A. sanctaerosae

 
This one ...
seems to be lacking the erect leg spines, the carapace has hair on it and a hint of a median carapace stripe, and I think the eye arrangement is a bit boxier. But yeah, similar enough to do a double take.

 
Now that I look on a big screen,
I agree, not sanctaerosae. It's way out of range of that sp also, which I hadn't noticed. I'm going to have to check, but I thought we only had sanctaerosae and littoralis in FL, and that's not littoralis. It does not resemble any of the Arctosa on Bugguide other than sanctaerosae and looks like someone took that species and gave it extra fur.

 
I made ...
a data point map for Arctosa 3 years ago if you haven't seen it ... Hogna is still on my to-do list.

Yeah totally.
There are a bunch of Hogna in Florida though that we don't have examples to compare to though so that's my suspicion.

 
I'd bet
any amount of money that this is Arctosa.

 
That's tempting.
Lol. Seriously, do you dissect and ID them under a microscope? Being in Florida maybe you'll find one. I'd love to have this holding bin sorted! This isn't the only one like this in here, there are several others. I pulled this one out of Arctosa littoralis.

 
I'm pretty familiar with A. sanctaerosae
and the one that started this is more similar to that than any spider I've ever seen.

 
Hang on ...
looking at more I take back what I said about the leg spines being erect as I was just comparing to this one, I wonder why this one is so prickly compared to the others? Any idea what the ventral should look like?:


Edit: part of the diagnosis for A. sanctaerosae includes dorsal macroseta on tibia I, I don't see any on this one.

 
this one?
If you look at the other picture of the one you posted, those hairs are laying down. When you say you don't see dorsal macrosetae, do you mean on the one you posted, or the one of the thread?

 
I meant the one ...
on this thread, sorry.

 
The one I linked ...
to has plenty. Regarding the one I linked to I just thought it odd so many were erect in one image and laying flat in most (all?) of the others.

Sorry it didn't make sense the way I wrote that. In the edit I was pointing to the lack of macrosetae on tibia I as an example of one of the reasons I filed the one on this page here instead of as Arctosa sanctaerosae.

 
pale lycosid
What we need is a lateral view. I would not discount the possibility that this is Geolycosa xera. While known only from the central ridge xeric habitats, it would not be the first time that such a species has been found in a similar coastal habitat.

 
Hi, nice to see ...
you active here! I considered Geolycosa too before making this holding bin. Comparing another here that I think looks to be the same species as the one shown here that includes a nice shot of the eyes to another IDed as Geolycosa xera archboldi I couldn't help but notice the PMEs look significantly bigger on the mystery ones.
.

 
Hi Laura. I usually log in when asked, and Dave asked.
This is tricky, but the dorsal view leads me to believe the cephalic area is elevated, which would be typical of Geolycosa. But a lateral view would be more definitive. Characters like eyes are often helpful, but sometimes there are exceptions. For example, the crab spider eyes can be variable, and even within a genus what is typical for most species can be different for the odd one.

 
Need a specimen
Can anyone get one? To be clear, I mean "we" need a specimen, or a series of really good pics, to find out what this is. To me, this is Arctosa nr. sanctarosae with a hairy abdomen, although I bow to Dr. Edward's assertion that it could be a Geolycosa.

 
hairy abdomen
I agree there is a resemblance to Arctosa sanctaerosae. However, this species is atypical for Arctosa in that the other North American species have a color pattern. Also, Arctosa are noted for being remarkably non-hairy for wolf spiders. That, and proximity to Geolycosa species of similar color, plus the possible elevated cephalic area, led me to an educated guess of Geolycosa. It would, however, be exciting if it turned out to be an undescribed relative of A. sanctaerosae. Or for that matter, undescribed in another genus.

 
Although I still ...
suspect Hogna it wouldn't bother me a bit if these turned out to be an undescribed Arctosa, Geolycosa, Schizocosa, or something else totally unexpected (that would be cool!). I agree without someone sharing the genitalia preferably with an expert it's best to hold off placing them as I know there are other similar things. I spent a lot of time trying to figure these out when I made this bin and accepted that I couldn't do it based on what information was available to me and have been waiting for someone to submit genitalia or confirmed images of them (being that there are likely multiple similar species in this bin). Just want to be sure you know this is just a holding bin placed at family level of things I'd love to see IDed and that these are not placed as Hogna only "Hogna-like". :D

I do IDs in a few other places and try to direct people with these to also submit them here. A new one was added just yesterday that originally turned up on facebook ... unfortunately it looks like the image was taken several years ago so I don't think he can collect it, I did recommend if he were to collect another to have it sent out to be IDed though.

Perhaps start a thread in the forums requesting FL members keep an eye out for these and to obtain either clear genitalia images or have them sent out for identification?

My in-laws are in FL and we're long overdue for a visit, I don't know when that will happen though ... these were always in the back of my mind as something I hoped to see though I doubt I'd even find the time to look. :/

Spider similar to OP's (I think this is the best lateral we have at the moment):
