Etymology: The species epithet, a noun in apposition, from the Latin unguis (nail, claw), refers to the three claw-like structures found in the male palp PTV.

Diagnosis: Male pedipalp of W. unguis spec. nov. differ from W. luisi spec. nov. by having the PTV distal “claws” decreasing regularly in size and a narrower posterior lobe of the PTP ( Figs 15 View FIGURE 15 a–b). Female genitalia of W. unguis spec. nov. differ from W. sublestus Chickering, 1940 and W. pulverulentus Chickering, 1937 ( Chickering 1940: figs 61, 63) by having a bigger atrium, the detail of the Cd and having small AB ( Figs 11 View FIGURES 11 e–f).

Description: Male: Total length 4.37. Cephalothorax: length 1.87; width 1.37. Carapace glabrous, without pattern, lighter near the lateral and posterior edges, thoracic groove very difficult to see ( Fig. 9a View FIGURES 9 ). Sternum glossy, color pale yellow. Precoxal triangles present, more visible on coxae III–IV, slightly darker than the sternum ( Fig. 9c View FIGURES 9 ). Coxa II with two ventral projections, coxae III–IV with one ( Fig. 9b View FIGURES 9 ). Endites almost square-shaped labium length ca. 1/2 of endites, same color as sternum. Chelicera: width 0.32, length 0.77; frontally with stout macrosetae ( Fig. 9a View FIGURES 9 ); four promarginal and eight retromarginal teeth; fang length 0.47. Eyes: AER and PER straight in dorsal view ( Fig. 9a View FIGURES 9 ); ALE diameter almost twice as big as AME; posterior eyes subequal in size. Clypeus about 2 times the diameter of AME.Abdomen: pale yellow; dorsal, lateral and ventral surfaces covered without small gray patches ( Fig. 9 View FIGURES 9 a–c). Legs: light yellow; leg I and II with two pairs of ventral macrosetae on tibiae and metatarsi; length I 14.0; II 6.87; III 4.13; IV 8.12; formula I–IV–II–III. Pedipalp: light yellow, bulb and bRTA brown ( Figs 9 View FIGURES 9 d–f); length 2.70. Distal portion of the bRTA harp-shaped, flattened and transparent ( Fig. 11d View FIGURES 11 ). Bulb: PTV elongated, tip with three teeth increasing posteriorly in size; PTP flat and wide, with two lobes; PTs long and semi-transparent ( Fig. 14a View FIGURES 14 ); MA semi-cylindrical and projecting retrolaterally ( Fig. 11a View FIGURES 11 ).

Female: as in male except as noted ( Figs 10 View FIGURES 10 a–e, 11e–f). Total length 4.87. Cephalothorax: length 1.87; width 1.12. Chelicera: width 0.30, length 0.77; three promarginal and six retromarginal teeth; fang 0.357. Coxae II–IV with dark prolateral markings. Abdomen without lateral spots ( Fig. 10b View FIGURES 10 ). Leg length: I 11.87; II 7.0; III 3.87; IV 8.12; Pedipalp 2.70, with a row of eight retrolateral macrosetae ( Fig. 10a View FIGURES 10 ). Epigyne dark, with semi-transparent cuticle; Co on the base of a big atrium ( Fig. 10d, e View FIGURES 10 ; 11f View FIGURES 11 ). Vulva: Cd long and narrow with small AB before the spermatheca; S sub-spherical; Fd long and thin, projecting anteriorly ( Fig. 11e, f View FIGURES 11 ).

Variation: Males: total length mean 4.37 (range: 4.12 to 4.62), carapace length mean 1.92 (range: 1.87 to 2.0); width mean 1.32 (non variable). Females: total length mean 4.71 (range: 4.62 to 4.75), carapace length mean 1.84 (range: 1.75 to 1.87); width mean 1.25 (non variable).

Distribution: Known only from the type locality ( Fig. 15b View FIGURE 15 ).

Biology: All specimens were collected in a Quercus forest with secondary plant growth. Adult specimens were found in May and October 2012. Specimens were caught by beating and direct collecting over vegetation.
