Type material.

Holotype ♀ (TRU-XZ-ANY-00016), China: Xizang Autonomous Region, Linzhi City, Chayu County, Cibagou National Nature Reserve (28°46.62′N, 97°0.86′E, ca 2880 m), 24 Jun. 2023, C. Wang et al. leg. Paratypes 4♀ (TRU-XZ-ANY-0017-0020), same data as for holotype; 2♀ (TRU-XZ-ANY-0021-0022), Cibagou National Nature Reserve (28°41.43′N, 97°2.86′E, ca 2570 m), 25 Jun. 2023, C. Wang leg.

Etymology.

The species is named after Mr Yejie Lin, who contributed to the taxonomic study of Chinese Anyphaena species and helped with species identification; noun (name) in genitive case.

Diagnosis.

Anyphaena yejiei sp. nov. is similar to that of A. shenzhen Lin & Li, 2021 in having a very long, distorted copulatory duct, but it can be easily distinguished by the medially located atrium and medially originated copulatory duct (Fig. 5G, H ), vs anteriorly located atrium and anteriorly originated copulatory duct in A. shenzhen ( Lin et al. 2021: fig. 6A, B). It also resembles that of A. cibagou sp. nov. in having a similar median septum, but it can be easily distinguished by the medially located atrium and much thinner and coiled copulatory ducts (Fig. 5G, H ), vs anteriorly located atrium and much thicken, and not coiled copulatory ducts in A. cibagou sp. nov. (Fig. 2D, E ).

Description.

Female (Fig. 5C, D, G, H, J ). Total length 7.84. Carapace 3.00 long, 2.44 wide. Abdomen 4.72 long, 3.00 wide. Clypeus height 0.17. Eye sizes: AME 0.11, ALE 0.16, PME 0.15, PLE 0.17. Measurements of legs: I 7.92 (2.12, 0.75, 2.10, 1.94, 1.01); II 7.18 (1.95, 0.78, 1.77, 1.72, 0.96); III 5.15 (1.36, 0.60, 1.14, 1.46, 0.59); IV 7.39 (2.05, 0.70, 1.77, 2.23, 0.64). Carapace pale yellow to brown, with sub-oval thorax and elevated cephalon bearing big, brown markings; fovea longitudinal, dark red. Chelicerae red-brown, with four promarginal and seven retromarginal teeth. Endites dark yellow, almost paralleled. Labium dark brown, with pale distal portion bearing dense dark setae. Sternum yellow, almost heart-shaped, with small dark-brown spots. Legs pale to brown. Abdomen elongated, dorsum fuchsia, with irregular yellow and fuchsia markings; venter pale, covered with brown spots laterally.

Epigyne-vulva (Fig. 5G, H, J ): longer than wide, with oval, medially located atrium separated by the sub-oval septum; copulatory openings beneath the lateral margin of atrium; copulatory ducts long, forming complicated coils and with medially located, bar-shaped accessory glands extending downward; spermathecae elongated, touched, with two sub-spherical portions; fertilization ducts lamellar, originate at the anterior portions of the outside spherical potions of spermathecae.

Male. Unknown.

Distribution.

Known only from the type locality in Xizang, China (Fig. 6B ).
