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. 25–27 , 77 ) and Nops finisfurvus n. sp. ( Figs. 44–46 , 79 ) by having a curved embolus; but it can be distinguished by its middle part strongly curved and a weakly sinuous tip ( Figs. 37–39 , 78 ). Description . Male ( holotype ): Carapace dark orange, elongated oval with a black and slightly elevated ocular tubercle ( Figs. 40, 41 ); pars cephalica not elevated, pars thoracica slightly sloping posteriorly ( Fig. 40 ), 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. 43 ), covered with scattered long setae. Labium orange, broad, fused to sternum along obsolete posterior groove, rounded and reborded in apical part ( Fig. 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. 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. 37–39 ), 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. 37–39 ). Abdomen grayish green dorsally with fine light gray lines forming a pattern ( Fig. 41 ), lighter ventrally, but darker in distal part around spinnerets, with only slightly sclerotized epigastric and postepigastric scuta ( Fig. 42 ). 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. 84 ).
