Predatoroonops schwarzeneggeri Brescovit, Rheims, and Ott , new species Figures 13 , 30–65 ; map 1

TYPES: Male holotype and female paratype from Fazenda Santa Helena, Pinheiral, 22 ° 319120S, 43 ° 599480W, Rio de Janeiro, Brazil (Nov. 5–11, 1999, A.D. Brescovit et al.), deposited in IBSP 66880 (PBI_OON 10909) and IBSP 66878 (PBI_OON 10910), respectively.

ETYMOLOGY: The specific name is a patronym in honor of the main actor in ‘‘Predator’’ movie, Arnold Schwarzenegger, who plays Major Alan ‘‘Dutch’’ Schaefer, the leader of a Special Forces elite team on a mission to rescue hostages from guerrilla territory in Central America.

DIAGNOSIS: Males of Predatoroonops schwarzeneggeri resemble those of P. billy and P. valverde by the long and dorsally curved distal apophysis at the chelicerae (figs. 15–16) but can be distinguished from these species by the larger median furrow, very narrow subdistal furrow, absence of condylar apophysis (fig. 13). Females can be easily distinguished from all other species by the large cordiform anterior receptaculum, with M-shaped apodema plate with lateral apodema process (fig. 64) in the internal genitalia.

MALE (PBI_OON 10909): Total length 1.88. Carapace 0.85 long, 0.68 wide. Eyes: ALE 0.10, PLE 0.10, PME 0.10, ALE-ALE 0.06. Carapace pale orange, with brown stripe along margin of cephalic area (fig. 38), anterolateral corners with sclerotized triangular projection (fig. 39). Chelicerae brown. Sternum, endites, and labium yellow. Clypeus with very small needlelike setae (fig. 13). Chelicerae anterior face with large triangular median furrow, subdistal narrow furrow, lateral subdistal apophysis, dorsally curved distal apophysis and subtriangular condyle apophysis (fig. 13). Abdomen dorsum white. Legs yellow, femur I 0.7 long. Leg spination: femur I v2-2-2; II d1-0-0; v2-2-2; tibia I v2-2- 2-2-2, II v2-2-2-2-2, III, IV d1-0-0; metatarsi: I–II v2-2-2. Male palp proximal segments yellow; cymbium yellow, bulb white, slender hyaline process with large base (fig. 43).

FEMALE (PBI_OON 10910): Total length 2.10. Carapace 0.86 long, 0.77 wide. Eyes: ALE 0.10, PLE 0.10, PME 0.12, ALE-ALE 0.08. Carapace without pattern. Chelicerae, endites, and labium yellow. Abdomen dorsum white. Leg spination: femur I v2-1-2; II v2-2-0; III, IV d1-0-0; tibia I 2-2-2-2-2, II 2-2- 2-2-2, III d0-1-0; p1-1-0; r0-1-0; IV p1-1-0;

v0-0-2; r1-1-0; metatarsus I 2-2-2-2, II 2-2-2- 2, III d0-1-0; v0-0-2; IV p0-1-1; v0-1-2; r0-1- 1. Internal genitalia with cordiform anterior receptaculum and cordiform posterior receptaculum (figs. 56, 64); M-shaped apodema plate with elongated apodema process (figs. 56–57, 64–65).
