Paralouatta is a platyrrhine genus that currently contains two extinct species of small primates that lived on the island of Cuba.

The initial description of the cranium included a proposal that Paralouatta varonai was a close Caribbean relative of the extant Alouatta (howler monkeys) of Central and South America,[1] but this taxonomic placement was called into question with the analysis of the dental remains.

[4] The postcranial morphology of Paralouatta suggests that it was partly terrestrial,[5] and a likely example of island gigantism.

[6] A second species of Paralouatta (P. marianae) has also been described from the Burdigalian (~18 million years old) Lagunitas Formation and is the largest Neotropic primate known of that epoch.

[4] Analysis of postcranial morphology suggests that Paralouatta was at least somewhat semi-terrestrial, making it the most terrestrial platyrrhine genus known.
