Why Mono Grande and Mono Rey Are Different

[Mono Grande From Internet Art Site]
There is some confusion as to exactly how many large unknown primates there are in South America, going by the information as given in standard cryptozoological sources. Two of the reported forms are Mono Grande (Big Monkey) commonly reported in Colombia, Venezuela, north-western Brazil and then the Eastern jungles of Ecuador and Peru; and then again Mono Rey (King Monkey) as reported in the border area of Peru and Bolivia, the Bolivian Lowlands, and then on towards the Mato Grosso in Brazil.

Mono Grannde from Karl Shuker's blog. He does nt see the obvious similartity to DeLoy's photograph. This is a
 pretty good drawing and it is similar to other witness' drawings that I have seen before from the same area (Venezuela)
 The muzzle is shown too small here, in contrast to the other photo, and it is probably not drawn big enough here.
I would suggest the other drawing represents a male and this one a female.

The idea generally seems to be that the Mono Grande [=?Sylvestre or "Forest-Dweller"=Sacharuna] is a smaller, more lightly built ape and it is frequently compared to the photo of DeLoy's Ape. It might weigh 100 to 150 pounds.

On the other Hand, the Mono Rey is a larger, more heavily-built ape with a weight estimated as over 200 pounds, minimum. Both types are mentioned in Harold Wilkins's book Secret Cities of Old South America, going on older traditions and old Spanish manuscripts. In the case of the Mono Rey, Wilkins calls it "King Kong" and equates it with the Sisimite in Mesoamerica and the Mapinguari in Mato Grosso. In the more recent book, Monster of the Madidi, it is described as looking like a large red howler monkey without a tail.

[The fact that Wilkins refers to it as "King Kong" is a clue as to why it is called the "King Monkey"]

 (Removing the tail which is specifically stated NOT to be there)
 This one is good in that is shows the implied throat pouches which helps it make loud calls

Found contradictory references to bears as "Ucu", confusing the matter, but still some core of unexplained descriptions remained. The "Unexplained" ones are as depicted here]


  1. Actually- I said the Mono Rey was like a large tail-less spider monkey (marimono) not a howler monkey. I'm pretty sure now the stories were just confused with the Ucamari, the Spectacled bear of the Andean ridges. The Mapinguari if it exists is said to be a ground sloth- Simon Chapman

  2. I am sorry, I have your book. You categorically and specifically stated the Mono Rey was like a large tailless howler and not a spider monkey at all: if not you then the sources you state said so. And the basic reports of the Mapinguari are nothing like a ground sloth, for which see the other listings on this blog. You are free to have your own opinion and you are free to change your mind. What was stated in print was what I quoted. I believe i have every reason to stick with my statements made here and subsequent facts I have learned tend to bear the construction out. Thank you for writing.

    Best Wishes, Dale D.
