TYPES: Male holotype and female paratype from RPPN Serra do Caraça, 20 ° 059S, 43 ° 299W, Catas Altas, Minas Gerais, Brazil, pitfall (Apr. 24–May 01, 2002, Equipe Biota) deposited in IBSP 136650 (PBI_OON 11845) and IBSP 136349 (PBI_OON 11847), respectively.

ETYMOLOGY: The specific name is a noun and refers to the fictional name by which Predators are known on their planet. The ‘‘yautja’’ live in a matriarchal clan-based society, with the strongest and most skilled of the group as the leader.

DIAGNOSIS: Males of Predatoroonops yautja differ from those of the remaining species by the strong setae on the clypeus (fig. 25); subdistal apophysis long and slender, distal apophysis inconspicuous on chelicerae (fig. 25). Females can be easily distinguished from those of the remaining species by the anterior receptaculum triangular, sulcated medially, truncated at tip, with the posterior receptaculum oval, nose shaped (fig. 282).

MALE (PBI_OON_11845): Total length 1.92. Carapace 0.90 long, 0.75 wide. ALE 0.10, PLE 0.10, PME 0.12, ALE-ALE 0.06. Carapace pale orange, without any pattern, anterolateral corners without slightly sclerotized triangular projections (figs. 343–344). Sternum, chelicerae, endites, and labium yellow. Clypeus with strong distinct needlelike setae (fig. 25). Chelicerae anterior face without median and subdistal furrow, subdistal apophysis long and slender, distal apophysis inconspicuous and condylar projection absent (fig. 25). Abdomen dorsum white. Legs yellow, femur I 0.73 long. Leg spination: femur: I d1-0-1; v1-2-2; II d1-0-1; v0-2-2; III–IV d1-0-1; tibia I v2-2-2-2-2, II v2-2-2-2-2, III–IV d0-1-0; p1-1-0; v0-1-2; r1-1-0; metatarsus I v2-2- 2-2, II v2-2-2-2, III d0-1-0; v0-1-2; r1-1-0; IV d0- 1-0; p1-1-0; v0-1-2; r1-1-0. Male palp proximal segments white; cymbium yellow; bulb white, with distal area elongated, laminar hyaline process short, curved, hyaline process short (figs. 350–352).

FEMALE (PBI_OON_11848): Total length 2.32. Carapace 0.85 long, 0.76 wide. ALE 0.10, PLE 0.10, PME 0.12, ALE-ALE 0.06. Abdomen dorsum pale white. Legs: femur I 0.83 long. Leg spination: femur I d1-0-0; v1- 2-2; II d1-0-0; v0-2-2; III d0-1-1; IV d1-0-1; tibia I v2-2-2-2-2, II v2-2-2-2-2, III d0-1-0; p1-1-0; v0-1-1; r1-1-0; IV d0-1-0; p1-1-0; v0- 1-2; r1-1-0; metatarsus I v2-2-2-2, II v2-2-2-2, III d0-1-0; v0-1-2; r0-0-1; IV d0-1-0; p0-1-1; v0-1-2; r0-1-1. Internal genitalia with anterior receptaculum triangular, sulcated medially and truncated at tip; posterior receptaculum oval, nose shaped ventrally, globose posteriorly; apodema plate short and curved distally, with long transversal and sinuous apodema process (figs. 282–283).
