Type material. BRAZIL: ♂ holotype, Santa Catarina: Criciúma [ 28°41'23.4"S, 49°21'29.1"W], 16.III.2017, L. Minotto leg. (MCTP-41580) GoogleMaps .

Etymology. The specific epithet is to be treated as a noun in apposition and refers to one of the forms and names taken by J.R.R. Tolkien’s arch villain ‘Sauron’ in the Lord of the Rings universe. Annatar is a pseudonym used by the Dark Lord Sauron to deceive the Elves into crafting the Rings of Power, ultimately leading to their downfall. Reference is made to the fact that species of Grismadox are mimetic and use mimicry to trick potential predators and prey alike.

Diagnosis. Males of Grismadox annatar sp. nov. can be distinguished from the males of all other known Grismadox species by the long embolus having almost the same length as the tegular neck ( vs. short in other species, less than 1/3 of the tegular neck length) and the embolus with seven keels ( vs. three, four or five in other species) ( Fig. 10D, E View FIGURE 10 ).
