They do have pedipalps; https://araneae.nmbe.ch/data/1697/Eresus_walckenaeri
That's what I meant ^^
I do think this will be a male, cause on a female they are slim all the way, also in slings.
But yeah this is very strange, I thought it came with the last molt aswell.
@Ungoliant Thanks for the information, I wasn't sure. I'm already planning on getting another E walckenaeri sling, I really wanted a female (not that I don't appreciate the cool colours of the males. :3
