Lileg.  Paratypes: 3 malesand 3 females( Ar29640–29645), same data as holotype.   Etymology.The specific name refers to the typelocality; adjective.   Diagnosis.This species resembles  P. bicornutusSimon, 1892(see Huber 2011b: 315, figs 1509–1513, 1539– 1540, 1560–1573) with similar male chelicerae ( Fig. 2D) and female genitalia ( Figs 2A–B) but can be distinguished by the wider and dorsally bent prolatero-dorsal process on the procursus (arrow in Fig. 1A), by the procursus less protruding ventro-medially (arrow 2 in Fig. 1B), by the presence of a large curved rigid process proximally on the uncus (arrow in Fig. 2C), and by the presence of appendix ( Fig. 2C).   Description.

Pedipalps as in Figs 1A–B; trochanter with a retrolateral apophysis provided with a pointed apophysis distally (arrow 1 in Fig. 1B); femur with a small retrolateral apophysis proximally and a distinct ventral hump (arrow 3 in Fig. 1B); procursus complex and hinged, with a large, long prolatero-dorsal process medially (arrow in Fig. 1A); bulbal apophyses as in Fig. 2C; 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.   FIGURE 1.  Pholcus bulacanensisYao & Li  sp. nov., holotype male. A–B. Pedipalp (A. Prolateral view, arrow points at wide prolatero-dorsal process on procursus; B. Retrolateral view, arrow 1 points at pointed apophysis on trochanteral apophysis distally, arrow 2 points at procursus ventro-medially, arrow 3 points at ventral hump on femur); C–D. Distal part of procursus (C. Prolateral view; D. Retrolateral view). a = appendix, b = bulb, e = embolus, pr = procursus, u = uncus.
