Loading spin-drier, one seen in Madagascar (5)
I believe the answer is:
indri
'one seen in madagascar' is the definition.
(type of lemur native to Madagascar)
'loading spin-drier' is the wordplay.
'loading' says the answer is hidden in the clue (the solution is part of the clue's 'load').
'INDRI' can be found hidden inside 'spin drier'.
(Other definitions for indri that I've seen before include "native of Madagascar" , "large primate" , "Species of lemur" , "Madagascan mammal" , "Animal" .)
