Gold jaguars Inca regularly displayed (5)
I believe the answer is:
auric
'gold' is the definition.
(thesaurus)
'jaguars inca regularly displayed' is the wordplay.
'regularly displayed' means one should take alternating letters (letters selected on a regular basis).
'jaguars'+'inca'='jaguarsinca'
The alternate letters of 'jaguarsinca' are 'AURIC'.
(Other definitions for auric that I've seen before include "Hugh -, Labour party leader" , "Golden" , "Pertaining to gold" , "French composer" , "- Goldfinger (Bond)" .)
