NC/TN lines
Can I get some clarification on the wiggly bits in NC/TN? I lived and worked in spider research in the western NC grey range for a decade and only ever saw recluses in the homes of recent TN transplants. Also in that range is the esteemed Highlands spider class, which has trained arachnologists for many years and has collection records each year for the area. Between 1999 and 2021 at least, no recluses have been found in western NC as part of that course. I suspect that the weird lines on this map better reflect the true range in NC and are closer to the UCR map, so I'm curious why so much more of NC is shaded in here, especially in a region that has had active arachnological research for decades and no compelling evidence I can find of having ever had recluses.

Can anyone tell me wha this spider is???
The spider is slightly furry and it is a medium size. It has only red legs and the rest is grayish brown check out my profile to see the picture

Hi Chris,
on my monitor the area you say is brown for reclusa looks grey, which is confusing since kaiba is listed as grey.

I think the L. kaiba region (light grey) is on the northwest tip of Arizona, which is slightly lighter than that of L. reclusa.

(edit) Just saw your comments below, please disregard my comment.

Ditto, and also....
My monitor shows the same. Also, just curious if you had later planned on adding range maps for laeta and rufescens. Thanks! -j

not ranging per se
I believe laeta and rufescens are occasionally found here and there, in isolated buildings, but I don't know of anywhere in NA they are established over a significant area. If I am mistaken, I too would like a map of where they can be found.

L. rufescens is absolutely es
L. rufescens is absolutely established across south Louisiana, but yes...mostly confined to buildings, as you have said. All specimens I have collected have been rufescens. I have been working on this for over two years now and have been corroborating with Dr. Rick Vetter, as well as have specimens confirmed by Tulane and University of Louisiana at Lafayette.

Confusing map colors
I've been thinking the same thing, too. I hope no one minds, but I just went ahead and changed the colors a bit in the key (forgive me, Chris, if you're still active here). I made reclusa dark grey and kaiba light grey. Not sure if that was the best, but at least that confusing brown is gone for reclusa.

Dark Grey - light Grey
Nice easy solution. Good thinking.

Looks good
on the Info page for the genus.
One minor comment: either, put the species names first, alphabetically, followed by their colour code; or, rearrange the colour codes from west to east (or vice versa), e.g., orange - , olive green - , red - , etc.
If it was my choice I would put the most important part first followed by colour code; that would be species names followed by colour.

I will move the names around. Thanks for your help!
