I scored some L. tredecimguttatus slings finally. After another molt or two I’ll take some pics.

Latrodecrus variolus

Once I receive my next shipment I’ll have 5/6 of the US species.

This brown widow (Latrodectus geometricus) was living in the back of our mailbox and had quite a pile of dead bugs below her. Brown widows are invasive, and we normally kill them, but I didn't have the heart to kill this one, so I am keeping her in a 32-oz. deli cup.

I re-housed my L. hesperus female the other day.
She is webbing it up and settling in nicely. I think I will nix the water dish idea and stick to misting 2-3 times a week, as that has been working for months for me. Also, it would be difficult to maintain with her webbing and thus far she seems to believe it's a flushable toilet - LOL.

These live in the driest places in the United States. There’s no need to do either of these. If you must provide water, lightly misting the web every couple months is fine.

^Yep, I have been lightly misting the web. I mist more frequently than you and it has been successfully working for me.
Removed water dish last evening.
Thanks for your input though.

Misting is important. That’s the way Latrodectus get their water...

Misting is important. That’s the way Latrodectus get their water...

They get the bulk of their moisture through their food. But some species (especially those from more humid climates) certainly won't say no to an occasional drink! Otherwise misting isn't really necessary, just an addition we can give them in captivity.

From what I have read L.mactans generally has the hourglass as one whole marking while L.hesperus generally has it seperated into two triangles as in my pics.

Also L.hesperus is confined to the western US while L.mactans is generally found in the eastern US.

This is incorrect. Latrodectus variolus has the separated hourglass. Hesperus are solid black with the red hourglass. Mactans has the red hourglass, and red at the end of the abdomen where it webs from.
