Pholcus huberi View in CoL sp. nov.

( Figs. 17–18 View FIGURE 17 View FIGURE 18 )

Types. Male holotype, 4♂, 10♀ paratypes, CHINA: Henan Province, Xinyang County, Mt. Jigong [31°48’N, 114°6’E], July 11, 2005, leg. Z. S. Zhang ( MHBU) GoogleMaps .

Diagnosis. Among its Pholcus relatives (see the remark of P. clavatus ), this species is very similar to P. harveyi sp. nov., P. songxian sp. nov., P. parayichengicus sp. nov. and P. yichengicus (Henan Province except P. yichengicus , Shanxi Province) in the shapes of the palpal bulb and epigynum, all with a biforked ventral apophysis of the trochanter ( Figs. 15I View FIGURE 15 , 17I View FIGURE 17 , 33I View FIGURE 33 , 46I View FIGURE 46 and 60I View FIGURE 60 ) and a long teat-shaped epigynal apophysis ( Figs. 15A View FIGURE 15 , 17A View FIGURE 17 , 33I View FIGURE 33 , 46A View FIGURE 46 and 60A View FIGURE 60 ). P. huberi sp. nov. can be distinguished from them by the shape of the tip of the procursus ( Figs. 17G–I View FIGURE 17 ), by the appendix without branched apophysis centrally ( Fig. 17H View FIGURE 17 ), also from P. harveyi sp. nov. and P. yichengicus by the cephalic region with brown central marks ( Fig. 17C View FIGURE 17 ).

Etymology. The specific name is a patronym in honor of Dr. B. A. Huber, a well-known arachnologist from Austria.

Description. Male (holotype): total body length 5.4: cephalothorax 1.7 long, 1.8 wide; abdomen 3.7 long, 1.8 wide. Prosoma shape as in Fig. 17C View FIGURE 17 . Leg I: 41.7 (10.7+0.7+10.1+17.5+2.7), tibia II: 7.6, tibia III: 5.0, tibia IV: 7.0; tibia I L/D: 67. Carapace short, broad and almost circular, ochre, with brown marks broadly connecting to ocular area. Cephalic region raised, without brown central marks, ocular area dark yellow. Clypeus 0.48, ochre, without marks. Distance AME–AME 0.05. Diameter AME 0.10, ALE 0.19, PME 0.17, PLE 0.17. Chelicerae as in Fig. 17E View FIGURE 17 , with pair of black distal apophyses carrying two modified hairs each ( Fig. 18D and 18E View FIGURE 18 ), pair of unsclerotized thumb-shaped apophyses proximolaterally and pair of unsclerotized rounded apophyses proximocentrally. Labium and endites light yellow. Sternum dark gray, with yellow patches centrally as in Fig. 17F View FIGURE 17 . Femora, patellae and tibiae ochre, with dark rings, metatarsi and tarsi ochre. Tarsal organ of tarsus 1 capsulate ( Fig. 18B View FIGURE 18 ). Abdomen cylindrical, pale ochre, dorsum with small brown patterns as in Fig. 17C View FIGURE 17 . Venter pale brown. Male gonopore with four epiandrous spigots as in Fig. 18C View FIGURE 18 . Six spinnerets ( Fig. 18I View FIGURE 18 ), ALS with six piriform gland spigots ( Fig. 18J View FIGURE 18 ), PMS with two spigots ( Fig. 18K View FIGURE 18 ) and PLS without any spigot ( Fig. 18L View FIGURE 18 ). Palps as in Figs. 17H and 17I View FIGURE 17 , bulb with brush-like uncus and long curved appendix. Procursus as in Fig. 17G View FIGURE 17 .

Variation. Tibia I in four other males: 9.4, 9.6, 9.6, 10.0. Body length in four other males 4.8–5.5.

Female: in general very similar to male. Total length of bodies 4.3–4.7. Female (one paratype, from Mt. Jigong), total length 4.3: cephalothorax 1.4 long, 1.6 wide; abdomen 2.9 long, 1.4 wide. Tibia I: 7.4. Distance AME–AME 0.05. Diameter AME 0.09, ALE 0.14, PME 0.12, PLE 0.13. Epigynum roughly triangular as in Fig. 17A View FIGURE 17 and 18A View FIGURE 18 , with a large teat-shaped apophysis on the top. Dorsal view as in Fig. 17B View FIGURE 17 , with a rainbowshaped sclerotized arch anteriorly and a pair of oval pore plates.
