( Fig. 19 )

Pholcus jixianensis Zhu & Yu, 1983 , in Zhu, Mao & Yu 1983: 136, f. 2a–h.

Diagnosis. Similar to P. suizhongicus , but can be distinguished from it by the shape of the tip of the procursus ( Figs. 19E–F ), by the short thumb-shaped appendix ( Fig. 19E ); and by the longer ventral apophysis of the trochanter ( Fig. 19C ).

Redescription. Male: A specimen measured (‘allotype’, data copied from Zhu, Mao and Yu 1983), total length 5.0: cephalothorax 1.6 long, 1.6 wide; abdomen 3.4 long, 1.6 wide. Leg I: 40.9 (9.4+12.5+16.5+2.5). Carapace short, broad and almost circular, ochre, with brown mark broadly connecting to ocular area. Cephalic region raised, with brown central marks, ocular area dark yellow. Clypeus slightly ochre, with yellow marks. Chelicerae with pair of black apophyses distally and pair of unsclerotized rounded apophyses proximolaterally. Labium and endites yellow. Sternum slightly ochre, with some regular yellow marks on it. Femora, patellae and tibiae ochre, with dark rings, metatarsi and tarsi brown. Abdomen cylindrical, pale ochre, dorsum with pairs of brown spots on it. Venter pale brown, without marks. Palps as in Figs. 19E and 19F , bulb with ear-shaped uncus and a small thumb-shaped appendix. Procursus as in Fig. 19D .

Female: in general very similar to male. A specimen measured (holotype, data copied from Zhu, Mao and Yu 1983), total length 5.3: cephalothorax 1.8 long, 1.8 wide; abdomen 3.5 long, 1.45 wide. Epigynum roughly rectangular as in Fig. 19A , with a small knob-shaped apophysis centrally. Dorsal view as in Fig. 19B , with a door-like sclerotized arch anteriorly and a pair of pine-cone pore plates.

Distribution. Known from type locality only.

Material. Types. Female holotype, male ‘allotype’ (labeled 82001), collected under a stone near the river, Lianhe Village , Ji County, Tianjin Municipality, China, July 30, 1982, leg. Z. X. Yu ( BMU); 4♂, 3♀ paratypes, same data as holotype ( TPPS) .

Material examined. CHINA: Tianjin: Ji County, July 30, 1982, leg. Z. X. Yu, only right palp of male and epigynum (from female holotype and male ‘allotype’) .
