Saltuarius kateae or Saltuarius wyberba

Thanks. Educate me, how can you tell the difference?

@ralph The butterfly-like spots on the back of the animal. It's like two circles that touch each other. This pattern is absent in S. kateae

Ok, the other Saltarius was a no-show, so I couldn't compare them in real life, therefor I had to base my guess on internet images. I saw some pretty similar patterns on a few of the photo's that show up in my search results when I search for S. kateae. On further inspection, only the first few pictures are actually of S. kateae, while the remainder of the search results are just of the genus. I guess only a couple of photo's of this species excists online.

@ralph There are several breeders of this species. You can find a lot more pictures on other platforms than Google.
