Species named after Tolkien's works

From Tolkien Gateway

Many species and even entire genera have been named after elements of J.R.R. Tolkien's legendarium. Some items on the list are junior synonyms, i.e. they were coined for a taxon that had an earlier published name and thus are not official according to the rules of zoological nomenclature. These are marked in the footnotes accordingly.
