Etymology
The specific name honours the former US Secretary of Defense Donald Rumsfeld, because his quote “there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns – the ones we don’t know we don’t know” applies to the describers view on what is known about mesophotic fish species. [2]
