Etymology.

The specific name refers to the type locality; noun in apposition.

Diagnosis.

The new species can be easily distinguished from all known congeners in the Pholcus phungiformes species group by the following combination of characters: procursus with curved prolatero-subdistal apophysis (arrow 1 in Fig. 9 C View Figure 9 vs. absent) and comb-like, sclerotized prolatero-distal apophysis (arrow 3 in Fig. 9 C View Figure 9 vs. absent), proximal apophysis of uncus on retrolateral part of uncus (arrow 1 in Fig. 10 C View Figure 10 vs. same plane or absent), epigyne with pair of lateral protrusions anterior to epigynal plate (arrow in Fig. 10 A View Figure 10 vs. absent).

Carapace brown, with brown radiating marks and marginal brown bands; ocular area yellowish, with median and lateral brown bands; clypeus and sternum brown. Legs yellowish, dark brown on patellae and whitish on distal parts of femora and tibiae, with darker rings on subdistal parts of femora and proximal and subdistal parts of tibiae. Opisthosoma yellowish, with dorsal and lateral brown spots. Chelicerae with pair of proximo-lateral apophyses (pa in Fig. 10 D View Figure 10 ), pair of distal apophyses (da in Fig. 10 D View Figure 10 ) with two teeth each, and pair of frontal apophyses (fa in Fig. 10 D View Figure 10 ). Palps as in Fig. 9 A, B View Figure 9 ; trochanter with long (6 × longer than wide), retrolaterally strongly bulged ventral apophysis; femur with retrolatero-proximal protrusion (arrow in Fig. 9 B View Figure 9 ) and distinct ventral protrusion; tibia with prolatero-ventral protrusion; procursus simple proximally but complex distally, with raised prolatero-subdistal edge bearing curved apophysis (arrow 1 in Fig. 9 C View Figure 9 ), membranous process (arrow 2 in Fig. 9 C View Figure 9 ) and comb-like sclerotized apophysis (arrow 3 in Fig. 9 C View Figure 9 ), ventro-distal apophysis (arrow 4 in Fig. 9 C View Figure 9 ), dorso-distal apophysis (arrow 5 in Fig. 9 C View Figure 9 ), and two slender dorsal spines (arrows in Fig. 9 D View Figure 9 ); uncus with distinct retrolatero-proximal apophysis (arrow 1 in Fig. 10 C View Figure 10 ) and scaly edge; “ pseudo-appendix ” curved, distally sclerotized (arrow 2 in Fig. 10 C View Figure 10 ); embolus weakly sclerotized, with transparent distal projections (e in Fig. 10 C View Figure 10 ). Retrolateral trichobothrium on tibia I at 3 % proximally; legs with short, vertical setae on tibiae, metatarsi, and tarsi; tarsus I with 35 distinct pseudosegments.
