Andean ruminant (5)
I believe the answer is:
'andean ruminant' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for llama that I've seen before include "S.American animal" , "This could carry your stuff" , "Andean 'camel'" , "South-American cud-chewing animal" , "A mall (anag.)" .)
