Figures 13 –24, 70– 76

Type. Male holotype from Pico del Este, Luquillo  , Puerto Rico (18 ° 16 ' 06.0" N, 65 ° 45 ' 32.0" W), 7–9.x. 1996, A. J. Vargas, deposited in IBSP 166242.

Additional material examined. 1 ♀ imm., same data as holotype, deposited in IBSP 166243.

Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Easily distinguished from other known congeners by having the carapace and dorsal part of abdomen immaculate, lacking the distinctly pattern ( Figs. 73, 75View FIGURES 70 – 76), translucent ventral keel on the anterior metatarsi occupying only about half the length of the metatarsus ( Figs. 17, 20View FIGURES 17 – 24). Also, males can be distinguished by a pear – shaped bulb and straight large embolus on a distinctively strongly curved base ( Figs. 70–72View FIGURES 70 – 76).

Description. Male (holotype): Carapace immaculate yellowish orange, broadly oval, with a slightly elevated black ocular tubercle, pars cephalica slightly depressed, pars thoracica short, sloping posteriorly ( Fig. 73View FIGURES 70 – 76); thoracic groove short ( Fig. 75View FIGURES 70 – 76). Two black, oval eyes of equal size separated by about two –thirds their diameter. Chelicerae, labium and endites yellowish orange, lighter than carapace. Endites broadly convergent, but not touching, distally rounded, medially narrowed, covered with scattered long setae ( Fig. 76View FIGURES 70 – 76). Labium much wider than long ( Fig. 76View FIGURES 70 – 76), separated from sternum by depressed groove, with distinct medial invagination at tip. Sternum yellowish orange, darker at the edge, about as wide as long, with few weak pits and numerous stiff setae around the edge ( Fig. 76View FIGURES 70 – 76). Coxae yellowish white. Legs pale yellow, femur I elongate, almost four times longer than wide ( Fig. 18View FIGURES 17 – 24); anterior legs with ventral translucent keel occupying only about half the length of the anterior metatarsi ( Figs. 17, 20View FIGURES 17 – 24), and a translucent fan –shaped extension of the membrane between the anterior metatarsi and tarsi ( Fig. 20View FIGURES 17 – 24); metatarsi I – III entire, metatarsus IV and tarsi divided into two subsegments (Figs. 13, 16); tarsi with three claws, inferior claw shorter than paired ones (Figs. 14, 19), anterior paired claws with 12 teeth ( Fig. 19View FIGURES 17 – 24) and posterior with 8 (Fig. 14). Tarsal organ exposed, large, with five pronounced, concentric marginal ridges and three large proprioreceptors ( Figs. 21, 22View FIGURES 17 – 24). Trichobothria present on metatarsi and tarsi in a single row, bases with semicircular rim bearing two slight longitudinal ridges ( Figs. 23, 24View FIGURES 17 – 24). Palp pale yellow, with tibia excavated ventrally; cymbium elongated pointed, prolateral surface densely covered with strong setae; with a pear shaped bulb ( Figs. 70–72View FIGURES 70 – 76); embolus straight and large, on a distinctively strongly curved base ( Figs. 70–72View FIGURES 70 – 76); tip of embolus with a fine and long extension. Abdomen immaculate light gray ( Figs. 74, 75View FIGURES 70 – 76). Spinnerets light gray, six, in typical caponiid arrangement. Total length 3.9. Carapace 1.8 long, 1.4 wide. Eyes 0.15 major diameter, 0.08 minor diameter. Leg measurements: I: femur 3.23 / patella 1.84 / tibia 2.72 / metatarsus 2.72 / tarsus 1.2; II: 3.4 / 1.22 / 2.96 / 2.96 / 1.73; III: 2.82 / 1.43 / 2.39 / 2.7 / 1.7; IV: 3.71 / 1.63 / 3.23 / 3.24 / 2.25. Leg formula: 4213. Sternum 2.23 long, 1.95 wide. Palpal tibia 1.05 long, 0.85 wide.

Female: Adult females unknown.

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