Thanks for the link, Pong. I see now, the whole genus did not transfer, just this species and perhaps a few others. :) Macracantha arcuata would be the correct scientific name, my mistake. Thanks for the correction, Pong.

PongWira, from my readings, I cannot find anything about a genus transfer of Gasteracantha. They seem to be two definitive genera. Do you have a source?
