combfooted spider ID. Latrodectus?

[pandinus]

what is this? i have no idea. i hope it is a latrodectus, but have no clue.

[alex]

It really looks like a Latrodectus.

Does the spider have a red/orange/yellow marking or hourglass on the underside of it's abdomen? Because this spider is large enough for that evident marking to be present. Otherwise I am not entirely sure it's a Widow.

Looks to be a Steatoda species to me. S.triangulosa? Don't think it is a Latrodectus though.

[Stormcrow]

Me neither, only one way to verify, look for a marking.

[pandinus]

do all latros have the marking?

[conway]

when adulthood is reached i believe, although im not sure, some may have them at an early age before adults

[Stormcrow]

There should be L.hesperus and maybe even L.variolus in Oklahoma. But the marking is quite evident in young spiderlings. L.variolus can be a single triangle or square or incomplete hourglass, L.hesperus can have a complete to nearly complete hourglass.

But some foreign species such as Africa's L.indistinctus don't have a marking on the underside of the abdomen but rather on the dorsal near the spinnerets.

John,

It's a common house spider that has spread world-wide through human intervention...these guys are everywhere. Probbaly Achaearanea tepidariorum.

These guys can be found just about world-wide.

Color patternation varies widely. They are related to Latrodectus but are not know to be dangerous.

I have let these guy colonize my bug room. They do an excellent job of catching most flying pests that manage to get in there as well and most pinhead and other small escaped crickets.
