Lioness grabs tail of unlucky antelope (5)

I believe the answer is:

nyala

I'm a little stuck... Click here to teach me more about this clue!

'antelope' is the definition.
(nyala is a kind of antelope)

'lioness grabs tail of unlucky' is the wordplay.
'lioness' becomes 'nala' (I am not sure about this - if you are sure you should believe this answer much more).
'grabs' is an insertion indicator.
'tail of' suggests the final letters.
The last letter of 'unlucky' is 'y'.
'nala' going around 'y' is 'NYALA'.

Can you help me to learn more?

(Other definitions for nyala that I've seen before include "South African resident" , "Spiral-horned antelope" , "South African native" , "wild animal" , "African animal" .)

I've seen this clue in The Independent.
