Hi,
I can't think of any specific MIDI files but I suggest you search for a bunch of bossa novas on MIDI search engine: http://www.midisite.co.uk/midi_search/

Generally, standard MIDi files (GM) aren't that great for drums and percussion tracks but you never know. You might find something usable. Lots of creative copy pasting to do but you might end up with something reasonable enough to sound like latin drums/percussion.

good luck,

-ED-
