ETYMOLOGY: The specific name refers to the South/Central American country Val Verde, a fictional country created for ‘‘Predator’’ by Hollywood filmmakers, to avoid getting into legal or diplomatic disputes.
DIAGNOSIS: Males of
Predatoroonops valverde
resemble those of
P. schwartzaneggeri
and
P. billy
by the presence of a long, dorsally curved distal apophysis in the chelicerae (figs. 13, 15) but can be separated from these species by the longer subdistal furrow, short subdistal apophysis (figs. 16, 132). Females can be easily distinguished from those of the remaining species by the triangular anterior receptaculum, cylindrical posterior receptaculum with slender tip (figs. 70–71, 150–152).
MALE (PBI_OON_11077): Total length 1.95. Carapace 0.90 long, 0.75 wide. ALE 0.10, PLE 0.10, PME 0.12, ALE-ALE 0.08. Carapace pale orange, without any pattern, anterolateral corners with slightly sclerotized triangular projections (fig. 134). Sternum, chelicerae, endites, and labium yellow. Clypeus with very small needlelike setae (fig. 16). Chelicerae anterior face with long, recurved triangular median furrow, short subdistal narrow furrow, narrowed lateral subdistal apophysis, long dorsally curved distal apophysis and condylar projection absent (fig. 16). Abdomen dorsum white. Legs yellow, femur I 0.80. Leg spination: femur: I v2-2-1; II v2-2- 0; III d1-1-0, tibia I v2-2-2-2-2, II v2-2-2-2-2, III v0-1-1; IV p1-0-0; v0-1-1; r1-1-0; metatarsi I v2-2-2-2, II v2-2-2-2, III v1-2-2; IV p0-0-1; v0-1-2; r0-0-1. Male palp proximal segments white; cymbium yellow; bulb white; large slender hyaline process (fig. 137).
FEMALE (PBI_OON_11077): Total length 2.10. Carapace 0.95 long, 0.82 wide. ALE 0.10, PLE 0.10, PME 0.12, ALE-ALE 0.06. Abdomen dorsum pale white. Legs: femur I 0.75. Leg spination: femur I v2-2-1; II v2-2-0; III d1-1-0, tibia I v2-2-2-2-2, II v2-2-2-2-2, III–IV v0-1-1; metatarsus I v2-2-2-2, II v2-2- 2-2, III v0-1-2; IV p1-1-0; v0-1-0; r1-1-0. Internal genitalia with triangular anterior receptaculum and posterior receptaculum with slender tip (figs. 70–71, 150–152); elongated apodema plate flattened, not enlarged laterally, with small and globose apodema process (figs. 70–71).
