TYPES: Male holotype and female paratype from Fazenda Santa Helena, 22 ° 349S, 44 ° 219W, Pinheiral, Rio de Janeiro, Brazil (Nov. 5–11, 1999, A.D. Brescovit et al.), deposited in IBSP 66861 (PBI_OON 10919) and IBSP 66875 (PBI_OON 10920), respectively.

ETYMOLOGY: The specific name is a patronym in honor of John McTiernan, the director of the first movie in the ‘‘Predator’’ series.

DIAGNOSIS: Males of Predatoroonops mctiernani differ from those of the remaining species by the subdistal apophysis short and distal apophysis with three branches on chelicerae (figs. 27, 403–405). Females can be easily distinguished from those of the remaining species by the epigynum with fused anterior and posterior receptacula, apodema process with curved extremities (figs. 397–398).

MALE (PBI_OON 10919): Total length 1.69. Carapace 0.83 long, 0.64 wide. ALE 0.10, PLE 0.10, PME 0.12, ALE-ALE 0.06. Carapace yellow, without any pattern, anterolateral corners with sclerotized triangular projections (figs. 417–419). Sternum, chelicerae, endites, and labium yellow. Clypeus with very small needlelike setae (fig. 27). Chelicerae anterior face without median and subdistal furrow, subdistal apophysis short, distal apophysis long with three branches; condylar projection absent (figs. 27, 403– 405). Abdomen dorsum white. Legs yellow, femur I 0.65 long. Leg spination: femur I v2- 2-2; II v0-2-2; III d1-0-1; IV d1-0-0; tibia I v2- 2-2-2-2, II v2-2-2-2-2, III d1-0-0; v0-0-2, IV p1-0-1; v0-1-1, metatarsus I v2-2-2-2, II v2-2- 2-2, III v0-0-2; IV p0-0-1; v0-0-2. Male palp proximal segments and cymbium yellow, bulb white, distal area elongated, with long, flattened laminar process, hyaline process slender, sinuous (figs. 411–413, 423–425).

FEMALE (PBI_OON 10920): Total length 2.10. Carapace 0.85 long, 0.75 wide. ALE 0.10, PLE 0.10, PME 0.12, ALE.ALE 0.08. Carapace pale orange. Chelicerae fang with rounded median process. Abdomen dorsum with gray pattern. Legs pale orange, femur I 0.74 long. Leg spination: femur: I–II v2-2-2; III d1-0-1; IV d1-0-0; tibia I v2-2-2-2-2, II v2- 2-2-2-2, III v0-0-2, IV p1-0-1; v0-1-1, metatarsus I v2-2-2-2, II v2-2-2-2, III v0-0-2; IV p1-0-1; v0-0-2. Internal genitalia with fused anterior and posterior receptacula; apodema plate semicircular and flattened, and with long apodema process, which is curved at tip (figs. 397–398).
