Figures 12–13, 14d
Type material: Holotype ♂: MEXICO: Xamaticpac, (19°07’30.1’’N, 97°04’0.1’’W, 1700 m), Feb. 9–17, 2014, L. Pérez-Miguel leg. (CNAN-T01358).
Etymology: The species epithet, a noun in apposition, from the Greak phantasma (phantom, apparition, ghost) refers to the common name under which Anyphaenidae are known.
Diagnosis: Male pedipalp of W. phantasma spec. nov. differs from that of W. imacullelus (Platnick 1974: fig. 87) by having a much wider PTV and ticker MA (Figs 12f; 13a); and from W. conchamonile spec. nov. by having a longer PTV with a triangular tip on a ventral view (Figs 3a; 13a), a shorter bifurcate MA and thicker PTP (Figs 14 c–d).
Description: Male: Total length 4.0. Cephalothorax: length 1.62; width 1.25. Carapace glabrous, without pattern, slightly darker in ocular area, thoracic groove very difficult to see (Fig. 12a). Sternum glossy, color pale yellow. Precoxal triangles present, more visible on coxae III–IV, slightly darker than the sternum (Fig. 12c). Coxae without spurs, coxae III−IV with dark marks on the prolateral surface. Endites same color as sternum, labium almost black, longer than wide, labium length ca. 1/2 of endites. Chelicera: width 0.30, length 0.77; same color as the cephalic region; four promarginal and one retromarginal teeth; fang length 0.57. Eyes: AER straight, PER slightly procurved in dorsal view (Fig. 12a); ALE diameter almost twice as big as AME; posterior eyes subequal in size. Clypeus about 1 time the diameter of AME. Abdomen: pale yellow; dorsal surface with small grey patches; lateral surface with three elongated black spots (Fig. 12b); ventral surface with three black spots: near the pedicel, over the epigastric furrow and anterior of the tracheal spiracle (Fig. 12c). Legs: light yellow, tibiae and metatarsi with dark rings distally; leg I and II with two pairs of ventral macrosetae on tibiae and metatarsi; length: I 14.25; II 7.65; III 5.25; IV 8.75; formula I–IV–II–III. Pedipalp: light yellow, bulb pale brown (Figs 12 d–f); length 2.70. Distal portion of the bRTA flattened and transparent, bifurcated on the tip (Fig. 13d). Bulb: PTV semi-triangular, long flat and transparent on a ventral view (Fig. 13a); PTP conical, almost as wide and long as the MA; PTs semitransparent, slightly longer than the PTP (Fig. 14d); MA bifurcated at its tip (Fig. 14d), projecting retrolaterally (Fig. 13a).
Female. Unknown.
Distribution: Known only from the type locality (Fig. 15b).
Biology: The only known specimen was collected on vegetation in a Quercus mixed forest with secondary plant growth in February 2014
