Thanks for this, I found this site ages ago and then lost it. This is the site that FINALLY put my tongue to rest about how to pronounce POECILOTHERIA!
When I first read the word Poecilotheria, I pronounced it correctly (I have a decent grasp of nomenclature and pronunciation) but when I heard everyone saying that they keep "Pokies" and various youTube video with people pronouncing it Poke-il-otheria - I thought I must be wrong and started saying it that way.
Then when I found this site you just linked for us, I was pleasantly surprised to read that the way I pronounced it in the beginning was correct... pee-suh-luh-THI-ree-uh
All these names are very tricky to get right.
