Figures 22 , 278–279 , 284–302 ; map 2

TYPES: Male holotype and female paratype from Estação Ecológica de Murici, 09 ° 159S, 35 ° 510W, pitfall, Murici, Alagoas, Brazil (Sept. 13–20, 2003; Equipe Biota) deposited in IBSP 68121 (PBI_OON 10991) and ( IBSP 68120 (PBI_10993), respectively.

ETYMOLOGY: The specific name refers to the character George Dillon, a former teammate of Dutch and current CIA agent, played by Carl Weathers in the movie ‘‘Predator.’’

DIAGNOSIS: Males of Predatoroonops dillon differ from those of the remaining species by the very long subdistal apophysis, concave at tip, with large base and by the conical, short and curved distal apophysis (fig. 22). Females can be easily distinguished from those of the remaining species by the short anterior receptaculum, squared and massive posterior receptaculum and very long apodema plate (figs. 278–279).

MALE (PBI_OON 10991): Total length 2.00. Carapace 1.0 long, 0.6 wide. ALE 0.12, PLE 0.10, PME 0.14, ALE-ALE 0.06. Carapace orange, without any pattern, anterolateral corners with sclerotized triangular projections (figs. 286–288). Sternum yellow. Chelicerae, endites, and labium pale orange. Clypeus with very small needlelike setae (fig. 22). Chelicerae anterior face with median furrow short, subdistal furrow inconspicuous with median group of 3–4 setae, subdistal apophysis very long, concave at tip and with large base; distal apophysis short; conical and condylar projection absent (fig. 22). Abdomen dorsum pale orange. Legs yellow, femur I 0.9 long. Leg spination: femora: I–II v2-2-1, III–IV d1-0-1; tibia I v2-2-2-2-2, II v2-2-2-2-2, III d0-1-0; p0-0-1; v0-1-1; r0-0-1; IV d0-1-0; p0-1-1; v0-1-1; r0-1- 1; metatarsus I v2-2-2-2, II v2-2-2-2, III d0-0- 1; v0-1-1; r0-0-1; IV d1-0-1; p0-1-1; v0-1-2; r0-1-1. Male palp proximal segments white; cymbium yellow, bulb white, with elongated distal area, slender hyaline process very large and short laminar hyaline process (figs. 291– 293).

FEMALE (PBI_OON 10993): Total length 2.10. Carapace 1.0 long, 0.70 wide. ALE 0.12, PLE 0.12, PME 0.14, ALE-ALE 0.06. Female palp prolateral tibia with a prolateral, longitudinally oblique row of 3–4 very long setae (fig. 301). Abdomen dorsum orange. Legs: femur I 0.9 long. Leg spination: femora I–II v2-2-1; III d1-0-0; v0-0-1; IV d1-0-1; v0-0-1; tibia I v2-2-2-2-2, II v2-2-2-2- 2, III d0-1-0; p0-0-1; v0-1-2; r0-0-1; IV d0-1-0; p1-0-0; v0-1-2; r1-0-1; metatarsus I v2-2-2-2, II v2-2-2-2, III d0-0-1; v0-1-2; r0-1-1; IV d0-0- 1; p0-1-1; v0-1-2; r0-1-1. Internal genitalia with short, folded anterior receptaculum and squared, solid posterior receptaculum that appears globose in posterior view; apodema plate very long, flattened at basis with slender and curved apodema process (figs. 278–279).

OTHER MATERIAL EXAMINED: BRAZIL: Alagoas: Murici, Estação Ecológica de Murici, 09 ° 159S, 35 ° 510W, Sept. 13–20, 2003, pitfall (Equipe Biota, IBSP 68119, PBI_OON 10992), 18.

DISTRIBUTION: Known only from the type locality, in the state of Alagoas, Brazil. This is the northernmost record of the genus (map 2).
