Name for word (rather than letter) "palindromes"?

Some among you must know. What’s the name for a phrase where the words repeat like a palindrome (but the words themselves aren’t palindromic)? For example, the species and subspecies “sapiens sapiens,” but with more words on both ends (“X Y sapiens sapiens Y X”). Thanks!

You mean like Deadbeat Dad Beat Dead?

Exactly.

Word-unit palindromes.
