Here's an etude I wrote out for a student a while back. We were exploring Latin Rhythms on the vibes. It's a little tricky.
Here are comping examples based over the tune 'Quet Nights'. There are 3 examples. Each one varies a little bit. The last 2 especially work well with no accompaniment. For example if you comping in duo with only a flute.
Check out the rhythms and the consistency of the rhythms. They repeat over and over to create a groove.
Check out these little snippets of comping based on a Brazilian feel. I basically took the guitar and bass parts and put them together. I added seconds to the bass line to add a percussive sound to the rhythm. The guitar more so than the piano plays a very rhythmic part in this music. Also that fact that I grew up playing guitar, I was drawn to this instrument. Listen to real Brazilian music and check out the guitar. You'll hear these rhythms. Try and recreate them with the feel that you hear.
