Nops blandus: Armas, 2010: 60  (misidentification, only male paratype).

Types. Male holotype from Isla Caja de Muertos, Puerto Rico (17 ° 53 ' 15.7 " N, 66 ° 31 ' 37.2 " W); 24.vii. 2010. L.F. Armas & A. Perez–Asso, deposited in IBSPAbout IBSP 166240. Male paratype, same data as holotype, deposited in IBSPAbout IBSP 166241.

Etymology. The specific name is a patronymic in honor of Ingi Agnarsson, for his help and support during fieldwork in Puerto Rico looking for caponiids.

Diagnosis. Males of Nops agnarssoni  n. sp. resemble those of Nops blandus  ( Figs. 25 –27View FIGURES 25 – 31, 77View FIGURES 77 – 80) and Nops finisfurvus  n. sp. ( Figs. 44 –46View FIGURES 44 – 50, 79View FIGURES 77 – 80) by having a curved embolus; but it can be distinguished by its middle part strongly curved and a weakly sinuous tip ( Figs. 37 –39View FIGURES 37 – 43, 78View FIGURES 77 – 80).

Description. Male (holotype): Carapace dark orange, elongated oval with a black and slightly elevated ocular tubercle ( Figs. 40, 41View FIGURES 37 – 43); pars cephalica not elevated, pars thoracica slightly sloping posteriorly ( Fig. 40View FIGURES 37 – 43), thoracic groove absent. Two black, oval eyes of equal size, separated by about two–thirds their diameter. Chelicerae orange. Endites 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. 43View FIGURES 37 – 43), covered with scattered long setae. Labium orange, broad, fused to sternum along obsolete posterior groove, rounded and reborded in apical part ( Fig. 43View FIGURES 37 – 43). Sternum orange, darker at the edge, oval, surface with fine reticular lines with few weak pits and numerous stiff setae around the edge ( Fig. 43View FIGURES 37 – 43). Coxae light orange. Legs 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, paired claws with 5 teeth, unpaired claw elongated and dorsally reflexed in all 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. 37–39View FIGURES 37 – 43), embolus strongly curved at middle part, distinctly shorter than tibial length, on a base of the same size as the width of the tibia, and a weakly sinuous tip ( Figs. 37–39View FIGURES 37 – 43). Abdomen grayish green dorsally with fine light gray lines forming a pattern ( Fig. 41View FIGURES 37 – 43), lighter ventrally, but darker in distal part around spinnerets, with only slightly sclerotized epigastric and postepigastric scuta ( Fig. 42View FIGURES 37 – 43). Spinnerets light gray, six, in typical caponiid arrangement. Total length 6.50. Carapace 3.40 long, 2.80 wide. Eyes 0.10 major diameter, 0.06 minor diameter. Leg measurements: I: femur 8.60 / patella 1.90 / tibia 9.90 / metatarsus 9.90 / tarsus 1.80; II: 8.70 / 1.30 / 10.40 / 10.10 / 1.30; III: 7.80 / 1.50 / 7.60 / 10.80 / 1.20; IV: 8.50 / 1.70 / 9.70 / 9.90 / 1.80. Sternum 1.90 long, 1.60 wide. Palpal tibia 1.40 long, 0.70 wide.

Female: Unknown.

Distribution: Known only from the type locality in Puerto Rico ( Fig. 84View FIGURES 84 – 85).
