Type material.
Holotype ♂ (TRU - JS 0806), 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 • 2 ♂ 6 ♀ (TRU - JS 0807–0814), same data as for holotype.
Etymology.
The specific name refers to type locality; noun (name) in apposition.
Diagnosis.
Yaginumaella daweishan sp. nov. resembles that of Y. ususudi (Yaginuma, 1972) in the general shape of copulatory organs, but can be distinguished by the following: 1) embolus (E) slightly curved, and with terminal broadened part (Fig. 41 B) vs curved into a C-shape and without similar broadened part (Bohdanowicz and Prószyński 1987: fig. 307); 2) retrolateral tibial apophysis (RTA) tapered into a pointed tip in retrolateral view (Fig. 41 C) vs almost equal in width from the base to the distal portion, and with a blunt tip (Bohdanowicz and Prószyński 1987: fig. 308); 3) epigynal hood (H) slightly longer than wide (Fig. 42 A) vs> 2.5 × wider than long (Bohdanowicz and Prószyński 1987: fig. 309).
Description.
Male (Figs 41, 42 C, D, F, G). Total length 4.46. Carapace 2.18 long, 1.75 wide. Abdomen 2.39 long, 1.36 wide. Eye sizes and interdistances: AME 0.51, ALE 0.30, PLE 0.28, AERW 1.59, PERW 1.54, EFL 0.98. Legs: I 4.76 (1.55, 0.83, 0.88, 0.90, 0.60), II 4.20 (1.25, 0.70, 1.00, 0.75, 0.50), III 4.82 (1.50, 0.63, 1.08, 1.08, 0.53), IV 5.02 (1.55, 0.63, 1.13, 1.18, 0.53). Carapace sub-square, with pair of bilateral pale setal bands and pair of longitudinal, dark brown stripes separated by central pale-yellow stripe on thoracic part. Legs pale except legs I darker, with three and two pairs of ventral spines on tibiae and metatarsi I. Dorsum of abdomen dark brown, with longitudinal, central pale band bearing sparse sliver spots, followed by several arc-shaped transverse pale stripes; venter pale, with central, longitudinal, irregular dark patch.
Palp (Fig. 41 A – C): femur length / width ratio ca 3.4; patella ~ 1.4 × longer than wide in retrolateral view; tibia as long as retrolateral tibial apophysis (RTA); retrolateral tibial apophysis tapering to pointed tip directed anteriorly; cymbium ~ 1.6 × longer than wide; tegulum ca 1.5 × longer than wide, with posteriorly extended posterior lobe (PL); embolus (E) originating at ca 9 o’clock position, slightly curved, and terminating at 12 o’clock position, with broadened terminal part.
Female (Fig. 42 A, B, E). Total length 4.63. Carapace 1.77 long, 1.40 wide. Abdomen 2.80 long, 1.97 wide. Eye sizes and interdistances: AME 0.47, ALE 0.23, PLE 0.20, AERW 1.30, PERW 1.25, EFL 0.90. Legs: I 4.23 (1.30, 0.75, 1.00, 0.70, 0.48), II 3.94 (1.20, 0.68, 0.93, 0.65, 0.48), III 4.84 (1.50, 0.68, 1.05, 1.08, 0.53), IV 5.02 (1.55, 0.63, 1.13, 1.18, 0.53). Habitus (Fig. 42 E) similar to that of male except darker.
Epigyne (Fig. 42 A, B) approximately as long as wide, with pair of hoods (H) posteriorly to copulatory openings (CO), and ~ 1.5 × longer than wide; atrium (At) oval, located anteriorly; copulatory ducts (CD) broad, forming complicated path; spermathecae (S) almost oval.
Distribution.
Known only from the type locality in Yunnan, China (Fig. 47).
