description: Putaoa huaping new species (Figs. 1-11)
Etymology. The species epithet is a noun in apposition, taken from the type locality.
Types. Male holotype, Cujiang Station, Huaping National Nature Reserve, Guangxi Prov., alt. 850 m, N25.60338°, E109.90554°, coll. L. Tu, 3 Nov. 2007 (#1386; Deposited in California Academy of Sciences, San Francisco, CAS). Paratypes: 1 female (same data as holotype, CAS); 1 male, 8 females, Longtangjie Village, Cujiang Station, Huaping National Nature Reserve, Guangxi Prov., alt. 802 m, N25.60405°, E109.90138°, coll. K. Liu, 6 Nov. 2007 (#1372; Deposited in Capital Normal University, Beijing); 1 male, 1 female, Xietangwan Village, Cujiang Station, Huaping National Nature Reserve, Guangxi Prov., alt. 804 m, N25.60235°, E109.90889°, coll. K. Liu, 4 Nov.2007 (#1354; deposited at Museum of Comparative Zoology, Harvard University); 2 females, Xietangwan Village, Cujiang Station, Huaping National Nature Reserve, Guangxi Prov., alt. 804 m, N25.60235°, E109.90889°, coll. K. Liu, 4 Nov. 2007 (#1354; deposited at American Museum of Natural History, New York).
Diagnosis: Males of P. huaping can be most easily distinguished from other pimoid species by a series of extremely large and robust macrosetae on the pedipalpal tibia (Figs. 3 A, 5B, C, E); these macrosetae are thicker and more numerous than those of its sister species, P. megacanthus. The unique shape of the PEP, highly bifurcated, is also diagnostic (Fig. 3 B, 6A-C, F). Females of P. huaping are diagnosed by the rather flat epigynum with lateral openings (Figs. 4 A-C).
Description.
Male (holotype; Figs. 1 A-D; see also genus description). Total length 3.82. Cephalothorax 2.00 long, 1.7 wide, 1.15 high. Sternum 1.03 long, 1.00 wide. Abdomen 2.00 long, 1.68 wide. AME diameter 0.15. Clypeus height 1.48 times one AME diameter. Carapace with deep longitudinal fovea (Figs. 1 A, D). Chelicerae with three prolateral and four retrolateral teeth; stridulatory striae absent (Fig. 8 D). Legs annulated. Femur I 2.33 long, 1.17 times the length of cephalothorax. Metatarsus I trichobothrium 0.25. Metatarsus IV trichobothrium present. Pedipalp as in Figs. 3, 4, 5, 6, 8 A, B. Pedipalpal tibia with one prolateral and two retrolateral trichobothria.
Female (paratype, same locality as male; Figs. 2 B, C). Total length 3.92. Cephalothorax 2.00 long, 1.43 wide, 1.13 high. Sternum 1.00 long, 0.93 wide. Abdomen 2.45 long, 1.90 wide. AME diameter 0.16. Clypeus height 1.30 times one AME diameter. Chelicerae with five prolateral and four retrolateral teeth; stridulatory striae absent (Fig. 9 B). Legs annulated. Femur I 2.13 long, 1.07 times the length of cephalothorax. Metatarsus I trichobothrium 0.26. Epigynum as in Figs. 2 D, E, 4A-C and 8E, F.
Variation. Male cephalothorax length ranges from 1.95 to 2.35 (n = 4). Female cephalothorax length ranges from 1.60 to 2.40 (n = 23). Male total length ranges from 3.70 to 4.25 (n = 4). Female total length ranges from 3.15 to 5.10 (n = 23).
Natural History. Putaoa huaping has been collected in native forests in China at altitudes between 700 and 1,000 m. Their webs are horizontal, thin and flat, built on the rock walls found on the side of mountain’s roads, usually covered by mosses. During day time the spiders normally hide under the adjacent mosses. Distribution. Known from the Guangxi province, in south China.
