Psalmopoeus cambridgei and irminia slings difference

[Denxak]

Hello, I have a question regarding the way of determination of p. cambridgei and irminia slings. What is the outward difference between them? There are photos of my (presumably) p. cambridgei sling

 

[Rozwyrazowana]

My p.cambridgei has less visible markings on his abdomen. I think that my sling is also smaller than yours so it maybe just because of its size.

You'll know for sure when they reach around 2", the slings do look quite similar.

Got it, thanks for your reply

IME they're pretty much identical as slings so you'll need to wait until they hit juvie sizes to tell them apart.

Are those pictures of one you own or at a local pet store?
