03FA816DFFB4436AFF50FED2425991DE.taxon	diagnosis	Diagnosis. Grismadox resembles Myrmecotypus and Apochinomma by having a recurved PER and narrow carapace (Fig. 1 D – F), but it differs from both by the spiniform second pair of anterior abdominal setae (AS II) (vs. thin and unmodified in Myrmecotypus and Apochinomma) (Figs 2 A – B, 13 E). Grismadox resembles Mazax by having AS II spiniform but differs by the recurved PER (vs. slightly recurved or straight in Mazax), surface of the AS II serrated (vs. smooth in Mazax), and the pedicel collar shorter than the length of the epigastric scutum (vs. longer in Mazax) (Figs 2 B – D, 8 A; Silva-Junior et al. 2024: figs 4 E, 5 A, B). Additionally, Grismadox differs from these three genera by the presence of a branched retrolateral tibial apophysis with ventral and dorsal lobes (vRTA and dRTA), and CD fused anteriorly to the secondary spermatheca (ST II) (vs. RTA absent or unbranched and CD fused laterally to ST II in Mazax, Myrmecotypu s and Apochinomma) (Fig. 3 C – D).	en	Silva-Junior, Cláudio J., Pett, Brogan L., Bonaldo, Alexandre B.

03FA816DFFBD4362FF50FCEB438B9092.taxon	etymology	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.	en	Silva-Junior, Cláudio J., Pett, Brogan L., Bonaldo, Alexandre B.

Males of G. mboitui resemble those G. mazaxoides and G. karugua by the presence of squamose setae with brachia on the abdomen and coxae II and III translucent white. They share with G. mazaxoides tibia I ventral spination 3 - 2 and the straight embolus but differ by the absence of the long pre-embolar base and the embolus with four-and-a-half keels (pre-embolar base present and embolus with three keels in G. mboitui) (cf. Figs 12 C, G and 11 C, G). Differs from G. karugua by the embolus straight and tibia I ventral spination 3 - 2 (embolus curved and tibia I ventral spination 3 - 3 in G. karugua; Figs 12 G and 13 G). Females resemble those of G. mazaxoides by the presence of squamose setae with brachia on the abdomen, tibia I ventral spination 3 - 2 and coxae II and III translucent white but differs by CO anterolateral to ST II (CO far anterior to ST II in G. mazaxoides) and the cephalic area dark and thoracic orange (by carapace color uniformly black in M. mazaxoides) (cf. Figs 12 H, I and 11 H, I).	en	Silva-Junior, Cláudio J., Pett, Brogan L., Bonaldo, Alexandre B.
