Type material.

Holotype ♂ (TRU - JS 0819), China: • Yunnan Province, Pingbian Miao Autonomous County, Daweishan National Nature Reserve (22°54.81'N, 103°42.02'E, ca 2040 m), 15. V. 2024, C. Wang et al. leg . Paratypes • 3 ♀ (TRU - JS 0820–0822), same data as for holotype .

Etymology.

The species name refers to the type locality: Pingbian Miao Autonomous County; noun in apposition.

Diagnosis.

Yaginumaella pingbian sp. nov. resembles that of Y. erlang Wang, Mi & Li, 2024 in its habitus and general shape of copulatory organs, but can be easily distinguished by the following: 1) male palpal tibia approximately ~ as long as wide in retrolateral view (Fig. 45 C) vs wider than long (Wang et al. 2024: fig. 20 C); 2) central longitudinal band on thoracic part in male ~ 1 / 4 of carapace width (Fig. 46 C) vs <1 / 5 (Wang et al. 2024: fig. 21 C); 3) epigynal hood (H) strongly sclerotized, opened towards 6: 30 o’clock position (Fig. 46 A) vs weakly sclerotized, opened towards ca 7: 30 o’clock position (Wang et al. 2024: fig. 21 A). The female also somewhat resembles that of Y. moinba sp. nov., but can be easily distinguished by the copulatory ducts (CO), which are extending into L-shape at beginning (Fig. 46 B) vs approximately S-shape (Fig. 44 B – D).

Description.

Male (Figs 45, 46 C, E – G). Total length 4.37. Carapace 2.31 long, 1.76 wide. Abdomen 2.20 long, 1.19 wide. Eye sizes and interdistances: AME 0.52, ALE 0.30, PLE 0.28, AERW 1.63, PERW 1.56, EFL 0.98. Legs: I 4.79 (1.50, 0.78, 1.13, 0.85, 0.53), II 4.26 (1.30, 0.75, 0.95, 0.73, 0.53), III 4.56 (1.43, 0.70, 1.00, 0.95, 0.48), IV 5.08 (1.50, 0.65, 1.18, 1.20, 0.55). Carapace mainly orange-yellow, covered with dark and golden setae, with pair of lateral pale bands bearing pale setae and longitudinal, central pale stripe extending across thoracic part. Legs pale, mingled with orange-brown, with lateral dark brown stripes on femora I, and three and two pairs of ventral spines on tibiae and metatarsi I. Dorsum of abdomen brown, with longitudinal, central, broad pale band extending across whole surface and bifurcated at posterior 1 / 3; venter pale, with longitudinal, central inconsecutive green-brown stripes.

Palp (Fig. 45 A – C): femur length / width ratio ca 3.0; patella ~ 1.15 × longer than wide in retrolateral view; tibia almost as long as wide in retrolateral view; retrolateral tibial apophysis (RTA) tapered, longer than tibia, curved distally into pointed tip; cymbium ca 1.2 × longer than wide, with almost horizontal tip; tegulum nearly oval, with posteriorly extending posterior lobe (PL), embolus (E) originating at ca 8: 30 o’clock position of bub, curved into C-shape.

Female (Fig. 46 A, B, D). Total length 5.32. Carapace 2.20 long, 1.64 wide. Abdomen 3.24 long, 2.28 wide. Eye sizes and interdistances: AME 0.52, ALE 0.32, PLE 0.28, AERW 1.60, PERW 1.56, EFL 1.04. Legs: I 4.18 (1.25, 0.75, 1.00, 0.68, 0.50), II 3.94 (1.25, 0.70, 0.88, 0.63, 0.48), III 4.89 (1.58, 0.75, 0.93, 1.03, 0.60), IV 5.22 (1.58, 0.70, 1.18, 1.18, 0.58). Habitus (Fig. 46 D) similar to that of male.

Epigyne (Fig. 46 A, B) ~ 1.3 × wider than long, with pair of sub-triangular, anterior hoods (H) lateral to copulatory openings (CO); copulatory ducts (CD) run into L-shape at beginning, and with complex distal curves; spermathecae (S) without distinct border.
