Ballarin and Y. Li leg. Paratypes: 3 males and 3 females (Ar 29640–29645), same data as holotype. GoogleMaps
Etymology. The specific name refers to the type locality; adjective.
Diagnosis. This species resembles P. bicornutus Simon, 1892 (see Huber 2011b: 315, figs 1509–1513, 1539– 1540, 1560–1573) with similar male chelicerae ( Fig. 2 View FIGURE 2 D) and female genitalia ( Figs 2 View FIGURE 2 A–B) but can be distinguished by the wider and dorsally bent prolatero-dorsal process on the procursus (arrow in Fig. 1 View FIGURE 1 A), by the procursus less protruding ventro-medially (arrow 2 in Fig. 1 View FIGURE 1 B), by the presence of a large curved rigid process proximally on the uncus (arrow in Fig. 2 View FIGURE 2 C), and by the presence of appendix ( Fig. 2 View FIGURE 2 C).
Description. Male (holotype): Total length 6.22 (6.54 with clypeus), carapace 1.41 long, 1.88 wide, opisthosoma 4.81 long, 1.54 wide. Leg I: 61.6 (14.55 + 0.88 + 15.38 + 27.31 + 2.97), leg II: 40.71 (10.64 + 0.82 + 10.38 + 16.99 + 1.88), leg III: 26.21 (7.56 + 0.75 + 6.73 + 9.87 + 1.30), leg IV: – (10.00 + 0.75 + 8.72 + – + –); tibia I L/d: 83. Distance PME-PME 0.60; diameter PME 0.14; distance PME-ALE 0.04; distance AME-AME 0.05; diameter AME 0.09. Sternum wider than long (1.20/0.88). Habitus as in Figs 2 View FIGURE 2 E–F. Carapace yellowish, with brown marks medially and marginally; ocular area brownish, with two brown bands medially; clypeus yellowish; sternum brown. Legs brownish, distal parts of femur and tibiae yellowish, darker rings absent. Opisthosoma yellowish, with brown spots posteriorly and laterally. Ocular area elevated, each eye triad on top of a laterally directed eye-stalk, with a pair of long processes between eye triads, each with distal brush of setae, setae separated. Thoracic furrow absent. Chelicerae as in Fig. 2 View FIGURE 2 D, with a pair of large proximo-lateral apophyses, a pair of black distal apophyses, each with two cone-shaped teeth, and a pair of indistinct frontal apophyses. Pedipalps as in Figs 1 View FIGURE 1 A–B; trochanter with a retrolateral apophysis provided with a pointed apophysis distally (arrow 1 in Fig. 1 View FIGURE 1 B); femur with a small retrolateral apophysis proximally and a distinct ventral hump (arrow 3 in Fig. 1 View FIGURE 1 B); procursus complex and hinged, with a large, long prolatero-dorsal process medially (arrow in Fig. 1 View FIGURE 1 A); bulbal apophyses as in Fig. 2 View FIGURE 2 C; uncus with scales distally; appendix short and weakly sclerotized, with a small branch medially; embolus weakly sclerotized, with some nearly transparent projections distally. Retrolateral trichobothrium of tibia I at 6%; legs with short vertical setae on tibiae, metatarsi and tarsi; without spines and curved setae; tarsus I with 24 distinct pseudosegments.
Female: Similar to male, habitus as in Figs 2 View FIGURE 2 G–H. Total length 6.31 (6.73 with clypeus), carapace 1.63 long, 1.88 wide, opisthosoma 4.68 long, 1.50 wide; tibia I: 14.55; tibia I L/d: 86. Distance PME-PME 0.31; diameter PME 0.14; distance PME-ALE 0.05; distance AME-AME 0.04; diameter AME 0.08. Sternum wider than long (1.16/0.94). Ocular area without eye-stalks. Epigynum ( Fig. 2 View FIGURE 2 A) with a knob. Vulva ( Fig. 2 View FIGURE 2 B) with a sclerotized anterior arch and two rounded pore plates.
Variation: Tibia I in male paratypes (n=3): 13.14, 13.46, 8.33. Tibia I in another female paratype (leg I lost in the other specimens): 14.10.
Distribution. Philippines (Bulacan, type locality; Fig. 21 View FIGURE 21 ).
Natural History. The species was found in the entrance zone of the cave.
