The new dwarf boa was named after an Indigenous activist by scientists.
The previously unknown snake was up to 20 centimeters long and had a skin color similar to the boa constrictor.
The second part of the name pays homage to an Indigenous rights activist.
The finders reported that two specimen were found in the national reserve and private park.
"These snakes are a relic of time, they are animals so old that finding or bumping into one of them is a privilege," said MarioYanez of theINABIO.
The species has a vestigial pelvis, a characteristic of primitive snakes, and is taken as proof that snakes descended from lizards that lost limbs over millions of years.
The findings were published in a journal.
According to the ministry, the discovery brings to six the number of known species.
