Advertisement After reading this thread, I did a search and found a reference to an article: Rudloff J.-P. & D. Weinmann. 2010. A new giant tarantula from Guyana. Arthropoda Scientia 1 (1): 20-38. Apparently this article describes a new Theraphosa species called Theraphosa stirmi, and supposedly this is Theraphosa sp. "Burgundy." Edit: Martin H. informed me that this article (or rather, the journal issue) is hot off the printing machine and may technically not be published yet as it's in the process of being sent to the subscribers. Edit 2: Another person (author of the post in the link Draychen posted) told me this journal issue is available since Wednesday, so it looks like this is published information after all.
