Guanaco cousin (5)
I believe the answer is:
llama
'guanaco cousin' 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 "South American relative of the camel" , "South American beast of burden" , "Long-necked woolly animal" , "Alpaca-like animal" , "Even-toed camel relative" .)
