Reprint a new reptile (8)
I believe the answer is:
terrapin
'reptile' is the definition.
(I know that Testudinata parent taxon reptile)
'reprint a new' is the wordplay.
'new' is an anagram indicator.
'reprint'+'a'='reprinta'
'reprinta' with letters rearranged gives 'TERRAPIN'.
(Other definitions for terrapin that I've seen before include "Water tortoise" , "Partner I found for freshwater tortoise" , "Aquatic tortoise" , "Web-footed turtle" , "Hardback" .)
