perhaps you know, what kind of spider this is. I found it near Andasibe in Madagaskar. I think it looks really interesting. Thank you very much.
This spider closely resembles a Crablike Spiny Orb Weaver found in the U.S. in the genus Gasterocantha. Your spider is probably closely related.
Another try: Gasteracantha versicolor formosa ??? I hope, i don’t steal too much of your time.
Gasteracantha versicolor formosa, or the Thorn Spider looks correct, according to this site.
