Salticidae NJ ID confirm?

[Ghoulsnake]

I collected four jumping spiders this morning, three of which I hadn't seen in my area before (Passaic County NJ) so I was having trouble IDing. I believe they're all Naphrys pulex, would anyone be able to verify that? I believe two are males and one is female but I have no idea if they are mature because they're so small.

The two I believe are males:

The one on the right is the first one I found. That one has a very dark carapace and a significantly lighter abdomen so that was the one throwing me off.

The one I believe to be female:

Just something I noticed with her is she has stripes on the sides of her carapace. I didn't notice that with the other two.

Thank you in advance!

All look good for N. pulex. Depth of colouration is somewhat variable - a bit lighter or darker from one specimen to the next is common. From what I can tell the stripe on the side of the cephalothorax seems to be a female trait, whereas males seem to have a tan or orange colour there without a stripe.

Thank you so much for verifying! That is very helpful and I had no idea the stripes were a female trait. Does that apply solely to N. pulex or do other species display stripes as well? Does it have anything to do with maturity?
