Long-haired mammal related to the llama (6)
I believe the answer is:
alpaca
'long-haired mammal related to the llama' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for alpaca that I've seen before include "Fabric from wool of S American llama" , "woollen fabric" , "Andean beast of burden" , "Silky cloth" , "S American mammal related to the llama" .)
