Hi Allen I found your question very interesting and found a bit off information on the topic for you on a site, The IUCN Red list of Threatened species. I will post a link to the site where the P. anchietae is discussed.
I extracted the following from the site which I believe is the answer to your question.
"Justification:
Python anchietae has been assessed as Least Concern. This species has a wide distribution in unpopulated areas. While this species is considered rare and is sought for the pet trade, this threat is believed to be under control. Its remote range and presence in protected areas means this species is stable and unlikely to be globally threatened. Further research into harvest levels, particularly into the extent of illegal collecting, is recommended."
Hope this helps.
