Anyphaena wuyi sp. nov. ( Figs. 1–10 )

Type material. Holotype male, CHINA: Fujian Province, Wuyi Mountain, N 26°32’ E 116°25’, 25 May 2004, F. Zhang leg. (HU). Paratypes: two females and one male, same data as holotype (HU).

Additional material. CHINA, Guizhou Province, Daozhen, Dashahe Nature Reserve, 644m, N 29°04’ E 107°24’, one female, 25 August 2004, Z.S. Zhang leg. (HU).

Diagnosis. The new species resembles Anyphaena gertschi Platnick, 1974 ( Platnick, 1974: 239, figs. 65, 69, 72, 76) through the possession of round ventral knobs on all male coxae, elongated median apophysis, hooked conductor, long and coiled copulatory tubes, and epigyne without a hood, but differs from the latter by: (1) retrolateral tibial apophysis long, with a serrate lateral edge and short dorsal process located proximally; (2) kidneyshaped spermathecae large; (3) atrium situated anteriorly, nearly quadrate.

spiracle. Scale bar: 1, 2.0 mm; 4–5, 1.0 mm; 2–3, 0.5 mm.

Etymology. The species name is a noun in apposition, derived from the type locality. Description.

Male (holotype): Total length 6.40. Cephalothorax 2.90 long, 2.25 wide; abdomen 3.69 long, 2.16 wide. Carapace ovoid in dorsal view, widest between coxae II and III, abruptly narrowed anteriad at level of coxa I, posterior margin truncate, highest at level of dorsal groove, with sparse covering of short pale recumbent setae and with few long erect setae on front and eye area; with short pale distinct dorsal groove; surface of carapace yellow orange, with two longitudinal bands marked by black strikes running above lateral edges ( Fig.1 ). Clypeus height slightly less than AME diameter. Eyes round, narrowly ringed with black, arranged in two transverse rows; AER slightly recurved, PER slightly wider than AER and procurved when seen from above; AME dark, others pearly white. Diameter AME 0.12, ALE 0.16, PME 0.15, PLE 0.16. Distance AME­AME 0.02, AME­ ALE 0.01, PME­PME 0.10, PME­PLE 0.09, ALE­PLE 0.07. MOA 0.39 long, front width 0.28, back width 0.40. Chelicerae rather short, slender, setaceous; orange brown; with 3 promarginal teeth and 6 retromarginal minute teeth ( Fig. 2 ). Endites yellowish brown; longer than wide, somewhat convex ventrally, convex along lateral margins ( Fig. 3 ); anterior edge with clearly distinct serrula. Labium yellowish brown, slightly longer than wide, anteriorly truncate ( Fig. 3 ). Sternum pale brown, heart­shaped, widest point behind coxae II, front margin truncate, posterior margin abruptly narrowed and extending between coxae IV ( Fig. 4 ).

Abdomen elongate, ovoid ( Fig. 1 ), widest near middle, with sparse covering of short pale setae and with cluster of long curved erect setae at anterior end; with two pairs of indistinct muscle impressions; dark brown, with numerous small gray spots, those on posterior half forming five short thick chevrons; venter with median dark band, tracheal spiracle located approximately one­third the distance from genital groove to spinnerets ( Fig. 5 ). Six spinnerets.

Legs rather long, stout, dark brown, with sparse covering of short pale setae; all coxae with round knobs ventrally ( Fig. 4 ), the tips of knobs point to the sternum and covered with cusp­like short setae; all trochanters with distal deep notches on ventral surface; tarsi with two dentate claws, and sparse claw tufts composed of two rows of lamilliform setae that are greatly expanded at their distal ends. Leg spination: femora: I d1­1­1, p 0­2­1, r 0­ 1­1; II­IV d1­1­1, p 0­1­1, r 0­1­1; patellae: I­IV d1­0­1, r 0­1­0; tibiae: I­II d1­0­1, p 1­1­ 1, r 1­1­1, v 2­2 ­0; III­IV d1­0­1, p 0­1­1, r 0­1­1, v 1­2 ­2; metatarsi: I­II d2­2­2, v 2­2 ­0; III d0­1­0, p 1­1­1, r 1­1­1, v 2­2 ­2; IV d0­1­0, p 1­1­1, r 1­1­1, v 2­2 ­2. Leg formula: 1423.

Male palp as illustrated ( Figs. 6–8 ), tibia approximately twice as long as wide, somewhat flattened on ventral side, with a small blunt process near the tibial base ( Figs. 7–8 ); retrolateral tibial apophysis long, with a round tip, a serrated lateral edge and a short process dorsally, a cluster of long sinuous pale setae arise from the base of apophysis. Median apophysis elongated, racket­shaped, truncate tip, with two tiny pointed process near the tip. Conductor enlarged and hooked, narrowing gradually towards tip. Embolus short, slender, hidden by tegulum.

Female. Total length 6.12. Cephalothorax 3.33 long, 1.80 wide; abdomen 2.88 long, 1.44 wide. Eye diameters: AME 0.14, ALE 0.21, PME 0.17, PLE 0.20.

Distribution. China: Fujian, Guizhou.
