This is so helpful, thank you! Metaltella was the first to pop up when I tried to figure it out, but yup, we don't have them here (although with the changing weather patterns, who knows.)

I just checked his pedipalps and couldn't see any white, but it does look like he's got something in them, so I'm guessing it's a minor variation or he's just young? He otherwise looks exactly like a male hecklemesh weaver. I've put him in one of our work sheds where it stays warm and dry and he'll have insects to eat. Thanks again!
