Etymology. The specific epithet is derived from the type locality Bamian Mountain National Nature Reserve, noun. Diagnosis. The male of this new species is similar to that of Thiania longapophysis Yu & Zhang, 2022 ( Yu and Zhang 2022 : figs 7 A – D, 8 A, B) in the shape of palpal bulb, sperm duct and embolus, but can be distinguished by: 1) the angle between RTA and cymbium (Fig. 1 A ) smaller than that angle in T. longapophysis (fig. 8 A); and 2) the distal end of RTA bar-shaped (Fig. 1 A ), while barb-shaped in T. longapophysis (fig. 8 A). The female of this new species is similar to that of Thiania luteobrachialis Schenkel, 1963 ( Peng 2020 : fig. 352 a – c) in the shape of the epigynal window and the location of copulatory openings, but can be distinguished by the following characters: 1) proximal portion of copulatory ducts straight and V-shaped (Fig. 1 D ), while curved and U-shaped in T. luteobrachialis (fig. 352 c); and 2) spermathecae overlapping with copulatory ducts (Fig. 1 D ), while not overlapping with copulatory ducts in T. luteobrachialis (fig. 352 c). Figure 1. Thiania bamian sp. nov. A left palp, ventral view B ditto, retrolateral view C epigyne, ventral view D vulva, dorsal view. Scale bars: 0.2 mm. Description. Male ( holotype ) (Fig. 2 A, B ).

Chelicerae dark brown, promargin with one bicuspid tooth, retromargin with one tooth. Endites and labium brown, distal end pale yellow, with dark setae. Sternum yellow brown. Leg pale yellow to brown. Measurements of legs: I 7.27 (2.01, 3.03, 1.51, 0.72), II 5.04 (1.65, 1.76, 1.03, 0.60, 5.04), III 4.91 (1.52, 1.68, 1.22, 0.49), IV 4.82 (1.42, 1.80, 1.07, 0.53).

A male holotype, habitus, dorsal view B ditto, ventral view C female paratype, habitus, dorsal view D ditto, ventral view. Scale bars: 1 mm. Palp (Fig. 1 A, B ). Embolus long and thin, embolic disc distinct; retrolateral tibial apophysis long and thin, distal portion covered with many small granules, terminal end reached the antero-median portion of palpal bulb in retrolateral view; sperm duct obvious. Female ( paratype ) (Fig. 2 C, D ). Total length 5.49; carapace 2.58 long, 2.11 wide; abdomen 2.86 long, 1.51 wide. Clypeus 0.32 high. Carapace yellow brown, with dark eye file and margins. Eye sizes and interdistances: AME 0.44, ALE 0.25, PME 0.05, PLE 0.20, AER 1.56, PER 1.52, EFL 1.14. Leg pale yellow to brown. Measurements of legs: I 5.47 (1.59, 2.29, 0.95, 0.64), II 4.44 (1.40, 1.72, 0.78, 0.54), III 4.51 (1.43, 1.60, 1.02, 0.46), IV 4.71 (1.42, 1.77, 1.09, 0.43). Leg formula: 1432. Abdomen dorsum brown, edges darker and with white hair, median portion with one pair of dark patches, posterior portion with four dark triangular patterns; venter pale yellow, median portion with one pair of gray longitudinal lines. Color paler than that in male. Epigyne (Fig. 1 C, D ). Epigynal window circular. Copulatory openings oval, located on both sides of the epigynal window. Copulatory ducts with straight original portion and coiled terminal portion. Spermathecae shoe-shaped, slightly narrower than the copulatory ducts and overlapping with terminal portion of copulatory ducts. Distribution. Known only from the type locality (Fig. 6 ).
