Antelope found in many a land (5)
I believe the answer is:
nyala
'antelope' is the definition.
(nyala is a kind of antelope)
'in many a land' is the wordplay.
'in' indicates the answer is hidden within the clue.
'NYALA' is hidden in the letters of 'many a land'.
'found' acts as a link.
(Other definitions for nyala that I've seen before include "wild animal" , "Ruminant" , "Antelope of southern Africa" , "Large African antelope" , "crested antelope" .)
