Etymology. The specific name is a noun in apposition taken from Hispaniola  Island where these spiders inhabit.

Diagnosis. Males of Nops hispaniola  n. sp. resemble those of Nops gertschi Chickering  (see Chickering, 1967: figs 7–8) by having a straight embolus with strongly curved tip and a base with same width than tibia, but can be distinguished by having the embolus tip narrower and less sclerotized ( Figs. 57–59View FIGURES 57 – 63). Females can be distinguished by a thin and slightly convex anterior margin of receptaculum, with a median concavity on the posterior wall, and a very small membranous sac ( Figs. 52View FIGURES 51 – 56, 82View FIGURES 81 – 83). Also, males and females of Nops hispaniola  n. sp. with abdomen immaculate, lacking the dorsal pattern of dark transversal bands present in Nops gertschi  .

Description. Male (holotype): Carapace immaculate orange, elongated oval with a black and slightly elevated ocular tubercle ( Fig. 61View FIGURES 57 – 63); pars cephalica not elevated, pars thoracica slight sloping posteriorly ( Fig. 60View FIGURES 57 – 63), thoracic groove absent. Two black, oval eyes of equal size, separated by about two –thirds their diameter. Chelicerae light orange. Endites light orange except for anterior tips due a white membranous projection, wide, convergent but not touching, with middle part wider than the distal and proximal and forming an obtuse angle of about 120 degrees ( Fig. 63View FIGURES 57 – 63), covered with scattered long setae. Labium light orange, broad, fused to sternum along obsolete posterior groove, rounded and reborded in apical part ( Fig. 63View FIGURES 57 – 63). Sternum light orange, darker at the edge, oval, surface with fine reticular lines with few weak pits and numerous stiff setae around the edge ( Fig. 63View FIGURES 57 – 63). Coxae light orange. Legs light orange, formula 4123; metatarsi entire, anteriors with a median translucent ventral longitudinal keel and with a distal, translucent ventral extension of membrane between anterior tarsi and metatarsi; all tarsi subsegmented, with three claws, unpaired claw elongated and dorsally reflexed in anterior legs, without teeth. Trichobothria present on metatarsi and tarsi in a single row. Palp with tibia excavated ventrally; cymbium elongated rounded, ventral surface densely covered with strong setae, with globose oval bulb ( Figs. 57–59View FIGURES 57 – 63); embolus straight, distinctly shorter than tibial length, with curved, narrow and slightly sclerotized tip, and a base with same width than tibia ( Figs. 57, 59View FIGURES 57 – 63). Abdomen immaculate, light gray dorsally, with darker area around spinnerets ( Figs. 61, 62View FIGURES 57 – 63). Spinnerets light gray, six, in typical caponiid arrangement. Total length 6.60, carapace 2.60 long, 1.50 wide. Eyes 0.12 major diameter, 0.07 minor diameter. Leg measurements: I: femur 8.00/ patella 1.60 / tibia 9.70 / metatarsus 9.40 / tarsus 1.50; II: 8.80 / 1.40 / 9.40 / 9.50 / 1.70; III: 7.00/ 1.20 / 7.40 / 9.40 / 1.40; IV: 8.10 / 1.40 / 9.50 / 9.30 / 1.60. Sternum 1.60 long, 1.10 wide. Palpal tibia 1.00 long, 0.60 wide.

Female (paratype IBSP 166394): Carapace ( Fig. 69View FIGURES 64 – 69), chelicerae, labium, legs, coxae, endites and sternum as in the male. Abdomen as in the male ( Figs. 66, 67View FIGURES 64 – 69). Anterior plate (ap) weakly sclerotized, almost reaching proximal part of abdomen ( Fig. 64View FIGURES 64 – 69); external sclerotization of spiracles (ess) darker, large, anteriorly starting from lateral extensions of posterior plate (lep), extending posteriorly more than the width of posterior spiracles (ps), but ending before interior edge of posterior spiracles ( Figs 64View FIGURES 64 – 69, 82View FIGURES 81 – 83). Internal genitalia with a thin, slightly convex and sclerotized anterior margin of receptaculum (amr), and a very short membranous sac (ms) ( Figs. 65View FIGURES 64 – 69, 82View FIGURES 81 – 83). Spinnerets light gray, six, in typical caponiid arrangement. Total length 6.90. Carapace 3.00 long, 2.10 wide. Eyes 0.10 major diameter, 0.08 minor diameter. Leg measurements: I: femur 8.30 / patella 1.80 / tibia 9.80 / metatarsus 9.90 / tarsus 1.90; II: 8.90 / 1.40 / 7.40 / 7.20 / 1.80; III: 7.60 / 1.40 / 7.50 / 7.20 / 1.60; IV: 8.20 / 1.40 / 9.60 / 9.30 / 1.70. Sternum 1.80 long, 1.40 wide. Palpal tibia 1.30 long, 0.80 wide.

Variation. Male (n= 2): Total length 6.00− 6.60, carapace 2.30−2.60 long, femur I 7.60 −8.00 long. Palpal tibia 0.80 −1.00 long, 0.40−0.60 wide. Female (n= 2): Total length 5.90−6.90, carapace 2.20 −3.00 long, femur I 7.60−8.30. Palpal tibia 1.00− 1.30 long, 0.60−0.80 wide.

Distribution. Hispaniola  ( Fig. 85View FIGURES 84 – 85).
