Etymology. The specific epithet is derived from the Latin “ curvata ” (curved), referring to the curved retrolateral tibial apophysis, adjective. Diagnosis. The male of this new species is similar to that of Yaginumaella bulbosa Peng, Tang & Li, 2008 ( Peng et al. 2008 : figs 26–28) in habitus and the curved RTA , but can be distinguished by: 1) cymbium longer than wide (Fig. 4 A ), while wider than long in Y. bulbosa (fig. 27); 2) length of RTA is about 1 / 3 of the palpal bulb (Fig. 4 B ), while about 1 / 2 of the palpal bulb in Y. bulbosa (fig. 28); 3) RTA only extended to the basal 1 / 6 position of cymbium in retrolateral view (Fig. 4 B ), while to the basal 1 / 2 position of cymbium in retrolateral view in Y. bulbosa (fig. 28); and 4) embolus originates at about 7: 00 o’clock position (Fig. 4 A ), while originates at about 9: 00 o’clock position in Y. bulbosa (fig. 27). The female of this new species is similar to that of Yaginumaella lushiensis Zhang & Zhu, 2007 ( Zhu and Zhang 2011 : fig. 384 A, D, E) in the short and stout copulatory ducts and the shape of spermathecae, but can be distinguished by the following characters: 1) distance of copulatory openings as wide as the vulva (Fig. 4 C ), while about 1 / 3 width of the vulva in Y. lushiensis (fig. 384 D); 2) epigynal pockets located at the median portion of epigyne (Fig. 4 C ), while located on the anterior portion in Y. lushiensis (fig. 384 D); and 3) fertilisation duct about transverse (Fig. 4 D ), while oblique in Y. lushiensis (fig. 384 E).

Palp (Fig. 4 A, B ). Embolus long and thin, originates at about 7: 00 o’clock position; tegular lobe folds to retrolateral side; retrolateral tibial apophysis curved towards dorsal side at right angle from the middle. Female. ( paratype ) (Fig. 5 C, D ). Total length 4.94; carapace 2.74 long, 2.04 wide; abdomen 2.54 long, 1.63 wide. Eye sizes and interdistances: AME 0.41, ALE 0.27, PME 0.11, PLE 0.23, AER 1.81, PER 1.79, EFL 0.72. Chelicerae promargin with two teeth, retromargin with one tooth. Legs pale yellow. Measurements of legs: I 4.79 (1.63, 1.80, 0.76, 0.60), II 4.44 (1.71, 1.49, 0.69, 0.55), III 5.49 (1.82, 1.94, 1.08, 0.65), IV 5.23 (1.63, 1.87, 1.03, 0.70). Leg formula: 3412. Abdomen oval, dorsum black, with symmetric lighter yellowish central area, posterior portion covered with dense black and white long hairs; venter light yellow, with three longitudinal black stripes. Color darker than that in male. Epigyne (Fig. 4 C, D ). Epigynal window oval, located at anterior portion of epigyne. Copulatory openings slit-shaped, located at the lower lateral margin of the epigynal window. Copulatory ducts short and stout. Spermathecae tubular and intertwined. Distribution. Known only from the type locality (Fig. 6 ). Figure 6. Collection localities of Thiania bamian sp. nov. , Thiania flacata sp. nov. and Yaginumaella curvata sp. nov. GenBank accession number.
