Etymology.

The species is named after Mr Fu Shu, who helped us with specimens collecting in Linzhi, Xizang; noun (name) in genitive case.

Diagnosis.

Anyphaena shufui sp. nov. closely resembles that of A. rhynchophysa Feng, Ma & Yang, 2012 in epigyne-vulva structure, but it can be easily distinguished by the atrium, which is slit-shaped (Fig. 5E ), vs oval in A. rhynchophysa ( Feng et al. 2012: fig. 8).

Description.

Female (holotype; Fig. 5 A, B, E, F, I ). Total length 8.95. Carapace 3.95 long, 3.19 wide. Abdomen 5.76 long, 3.90 wide. Clypeus 0.30 high. Eye sizes: AME 0.11, ALE 0.20, PME 0.19, PLE 0.20. Legs: I 14.99 (4.14, 1.22, 4.45, 3.40, 1.78); II 13.69 (3.91, 1.21, 3.83, 3.25, 1.49); III 10.61 (3.23, 1.08, 2.65, 2.53, 1.12); IV 14.71 (4.40, 1.24, 3.64, 4.12, 1.31).

Epigyne-vulva (Fig. 5E, F, I ): wider than long; atrium anteriorly located, slit-shaped; copulatory openings located on the lateral sides of atrium; copulatory ducts widened at base, and then folded and acutely narrowed to tube-shaped portions, which curved medially and with oval, terminal accessory glands; spermathecae elongate-oval, touched; fertilization ducts lamellar.
