Janet: You may not be an expert in your own mind but to many of us here, you are our expert. It takes a lot of patience (which you obviously have) to take the time to check leaf shape, size etc. and then go searching for an exact match. I truly appreciate your efforts!
Jonna: I read something like that regarding a spider a few years ago and it turned out to be a hoax. From what I know, the most venomous spider in Guatemala is one we find here in Florida; The Brown Recluse Spider. In Guatemala it's called the Fiddleback Spider ... bad arachnid! We have a friend who was bitten by one years ago and ended up requiring surgery!
