Etymology. The specific name is taken from the Latin adjective uncatus (hook-shaped), in reference to the shape of the narrow anterior region of the cymbium, especially in retrolateral view.

Diagnosis. The males of Mimetus uncatus n. sp. differ from those of all other Mimetus species by the bicuspid subtegular apophysis and the hook-shaped cymbial apex.
