Figs 1D-F View Figure 1 , 3 View Figure 3 , 4B View Figure 4 , 6A View Figure 6

Type material.

Holotype ♂ (TRU-XZ-ANY-0004), China: Xizang Autonomous Region, Linzhi City, Bomi County, Gangyunshanlin Scenic Area (29°52.99′N, 95°33.59′E, ca 2680 m), 29 Jun. 2023, C. Wang leg. Paratypes 1♂7♀ (TRU-XZ-ANY-0005-0012), same data as for holotype.

Etymology.

The species name is a noun in apposition and comes from the type locality, Linzhi City.

Diagnosis.

Anyphaena linzhi sp. nov. closely resembles that of A. cibagou sp. nov., but it can be distinguished by the following: 1) the main portion of median apophysis is elongate-oval, more than two times longer than wide in ventral view (Fig. 3B View Figure 3 ), vs almost oval, and slightly longer than wide in A. cibagou sp. nov. (Fig. 2B View Figure 2 ); 2) the conductor is tapered at distal half in retrolateral view (Fig. 4B View Figure 4 ), vs acutely narrowed distally in A. cibagou sp. nov. (Fig. 4A View Figure 4 ); 3) the atrium is longer than wide, and the median septum lacks process (Fig. 3D View Figure 3 ), vs atrium is wider than long, and the median septum has laterally extended lamellar processes in A. cibagou sp. nov. (Fig. 2D View Figure 2 ); 4) the accessory glands are located medially on copulatory ducts (Fig. 3E View Figure 3 ), vs located terminally in A. cibagou sp. nov. (Fig. 2E View Figure 2 ); and 5) the spermathecae are about spherical (Fig. 3E View Figure 3 ), vs elongate-oval in A. cibagou sp. nov. (Fig. 2E View Figure 2 ). The male also somewhat resembles that of A. tibet Lin & Li, 2021 in having very similar palpal structure, but it differs in: 1) the ventral ramus of retrolateral tibial apophysis is anteroventrally extending, and about three times longer than the dorsal ramus in retrolateral view (Fig. 3C View Figure 3 ), vs upward extending, and less than two times longer than the dorsal ramus in A. tibet ( Lin et al. 2021: fig. 7C); 2) the conductor is smooth (Figs 3C View Figure 3 , 4B View Figure 4 ), vs serrated on the inner margin in A. tibet ( Lin et al. 2021: fig. 13B).

Description.

Male (holotype; Figs 1D, E View Figure 1 , 3A-C View Figure 3 , 4B View Figure 4 ). Total length 6.52. Carapace 2.82 long, 2.36 wide. Abdomen 3.76 long, 2.25 wide. Clypeus 0.11 high. Eye sizes: AME 0.12, ALE 0.16, PME 0.15, PLE 0.16. Measurements of legs: I 13.27 (3.42, 1.10, 4.12, 3.09, 1.54), II 11.87 (3.14, 1.06, 3.68, 2.69, 1.30), III 8.54 (2.66, 0.79, 2.24, 2.06, 0.79), IV 12.02 (3.31, 0.94, 3.17, 3.46, 1.14). Carapace almost oval, with elevated cephalon, and big, irregular, brown markings; fovea longitudinal, red-brown. Chelicerae yellow to gray-brown, with four promarginal and eight retromarginal teeth. Endites longer than wide, bearing clusters of dark-brown setae on inner portion of anterior margins. Labium darker than endites. Sternum almost heart-shaped, setose. Legs yellow-brown, with sub-triangular apophyses on the base of coxae. Abdomen elongated, dorsum pale to red-brown, with longitudinal, anteromedian pale band followed by two pairs of muscle depressions and two irregular dark patches medially; venter paler to dark brown.

Palp (Figs 3A-C View Figure 3 , 4B View Figure 4 ): patella slightly longer than wide, with sclerotized, disto-prolateral apophysis; tibia slightly curved medially, with almost half-round ventro-retrolateral apophysis at base and bifurcated disto-retrolateral apophysis, which has straight, bar-shaped ventral ramus directed towards ca 10 o’clock position apically in retrolateral view, and strongly sclerotized, lamellar dorsal ramus; cymbium longer than wide, with two slender, medially curved macrosetea on the distal portion of prolateral margin; bulb almost oval; tegulum swollen; subtegulum elongated, prolaterally located; median apophysis originates from the middle of retrolateral side of bulb, main portion elongated, with somewhat pointed tip; embolus thin, partly visible; conductor retrolateral to the main portion of median apophysis, strongly curved medially, and with tapered distal half extending anteroventrally.

Female (TRU-XZ-ANY-0006; Figs 1F View Figure 1 , 3D-F View Figure 3 ). Total length 8.41. Carapace 3.05 long, 2.50 wide. Abdomen 5.50 long, 3.64 wide. Clypeus 0.12 high. Eye sizes AME 0.10, ALE 0.15, PME 0.14, PLE 0.15. Measurements of legs: I 12.89 (3.26, 1.39, 3.60, 3.06, 1.58), II 11.40 (3.00, 1.22, 3.18, 2.74, 1.26), III 8.85 (2.52, 1.16, 2.05, 2.18, 0.94), IV 11.73 (3.12, 1.20, 2.87, 3.38, 1.16). Habitus (Fig. 1F View Figure 1 ) similar to that of male except having the dorsal abdominal pale band extending the whole surface, seven retromarginal cheliceral teeth, and lacking ventral apophysis on the base of coaxe.

Epigyne and vulva (Fig. 3D-F View Figure 3 ): wider than long; atrium almost hexagonal, anteriorly located; median septum almost linguiform; copulatory ducts curved, gradually thicken, with short, medially located accessory glands less than one-third the largest diameter of copulatory ducts in length; spermathecae sub-spherical, touched; fertilization ducts lamellar.

Distribution.

Known only from the type locality in Xizang, China (Fig. 6A View Figure 6 ).
