Hi, I hope some of you can read this message after 4 years of the last publication.
I am from Chile, and we are having a big issue with our monkey tree, they are dying with the same characteristic that you are presenting. We found several insects in the branches but not in the main stem. No fungus related and no problems with water. I belief is a reaction of the tree to multiple insect attack on the branches.
The problem is really urgent, we have 2% of the entire population already dead, and 80% with the same symptoms.
Did you see insects on the branches, is the plant still alive? Any other had seen something similar on this specie (Araucaria araucana)?
Cheers
