Wesleybrouwer to the rescue once again! Thanks a lot for the answers. So, basically it's just that Wikipedia/Wikispecies/Amphibanweb are all unupdated (which I've figured out already), and on top of that, the research is not yet completely supported. But right now it's most accurate to consider Agalychnis a genus of 14 species.
Thanks for the paper about it, I'm going to read it. Also, someone with a lot better English (and general understanding of the subject) than me should update Wikipedia... Hint hint, Wesleybrouwer![]()
