Howler monkeys ID in Brazil (1 Viewer)

Hello!

These howler monkeys were photographed in south Mato Grosso do Sul state, central Brazil, on two different occasions. I'm having a hard time identifying which Alouatta sp. they are, but my best guess is either A. guariba or A. caraya, or both of them. Can anybody help?

Thanks in advance!
