Type material.

Holotype: ♂, China, Jiangxi Province, Ji’an City, Yongxin County, Nanhua Mt., 26°50'22.02"N, 114°15'47.05"E, 1130 m, 3 October 2019, leg. Ke-ke Liu et al. Paratypes: 1 ♂, 2 ♀, with same data as holotype; 1 ♂ (right palp broken in collection), Zhongcun, 26°49'37.77"N, 114°13'14.55"E, 3 October 2019, leg. Ke-ke Liu et al.

Etymology.

The specific name is derived from the type locality, Nanhuashan; adjective.

Diagnosis.

The males of the new species are similar to Otacilia hengshan (Song, 1990) in having a hook-shaped embolus, semi-circular sperm duct and a clavate retrolateral tegular apophysis (see Hu and Zhang 2011: 62, fig. 9-11), but can be separated from it by the embolus with a trapezoid base (Figs 6D View Figure 6 , 7A, B View Figure 7 ) (vs. parallel-sided) and the thin clavate retrolateral tegular apophysis (Figs 6D, E View Figure 6 , 7A, B View Figure 7 ) (vs. thick). The females resemble O. hengshan in having narrow and convergent connecting tubes (see Hu and Zhang 2011: 62, fig. 13, 15), but can be separated from it by the epigyne with a broad sub-trapezoid median septum (Fig. 8C View Figure 8 ) (vs. slender).

Leg spination (Fig. 6A, B View Figure 6 ): femur I with two dorsal spines, femora II-IV with one dorsal spine each; femora I pv1111, II pv11, pv111 (right); tibiae I v22222222, II v2222222; metatarsi I v2222, II pv2222.

Colouration (Fig. 6A, B View Figure 6 ). Carapace yellow-brown, medially with radial, irregular dark brown mottled markings on surface and arc-shaped dark stripes around margin. Fovea distinct, black. Chelicerae yellow-brown. Endites and labium yellow, with abundant setae on surface. Legs yellow. Abdomen dark brown, with pair of large irregular spots on posterior of dorsal scutum, three light chevron-shaped stripes on sub-medial part, and yellowish arc-shaped stripe posteriorly; weak dorsal scutum in anterior half; venter with two pairs of W-shaped markings posteriorly.

Palp (Figs 6C-F View Figure 6 , 7 View Figure 7 ). Femoral apophysis well-developed, width longer than half of its length. Patella unmodified. Retrolateral tibial apophysis less than tibial length, bending inward to base of cymbium, with clear apophysis located retrolaterally at base and blunt apex in dorsal view. Sperm duct C-shaped, strongly sclerotized, around base of retrolateral tegular apophysis, distal tegular apophysis and embolus. Retrolateral tegular apophysis clavate, longer than distal tegular apophysis. Distal tegular apophysis ampulla-like, covering half of retrolateral tegular apophysis. Embolus with trapezoidal base and short hook-like tip.

Female (paratype). Habitus as in Fig. 8A, B View Figure 8 . Total length 3.91, carapace 1.84 long, 1.61 wide. Eye sizes and interdistances: AME 0.1, ALE 0.11, PME 0.09, PLE 0.09, AME-AME 0.06, AME-ALE 0.02, PME-PME 0.12, PME-PLE 0.06, AME-PME 0.10, AME-PLE 0.19, ALE-ALE 0.29, PLE-PLE 0.42, ALE-PLE 0.11. MOA 0.26 long, front width 0.23, posterior width 0.31. Chelicerae (Fig. 8A, B View Figure 8 ) with three promarginal (middle largest, distal smallest) and six retromarginal teeth (distal largest, proximal smallest, second to fourth equal in size, 5th and 6th with a same base). Abdomen (Fig. 14A, B View Figure 14 ) 2.03 long, 1.25 wide. Legs (Fig. 8A, B View Figure 8 ) measurements: I 7.77 (1.94, 0.72, 2.45, 1.84, 0.82); II 6.36 (1.63, 0.63, 1.78, 1.64, 0.68); III 5.31 (1.44, 0.60, 1.15, 1.32, 0.80); IV 8.26 (2.29, 0.69, 1.98, 2.22, 1.08). Leg spination (Fig. 8A, B View Figure 8 ): femora I-IV with one dorsal spine each; femora I p11111, p1111(right), II p111; tibiae I v22222222, II v22222222.

Epigyne (Fig. 8C, D View Figure 8 ). Epigynal plate mask-shaped, sub-medially with pair of oval copulatory openings, posteriorly with sub-trapezoidal median septum. Copulatory ducts, glandular appendages, connecting tubes and spermathecae distinctly visible through integument in intact epigyne. Copulatory ducts relatively broad, located between copulatory openings and glandular appendages, posteriorly with pair of large bean-shaped transparent bursae. Glandular appendages very short, partly covered by bursae, located on anterior of connecting tubes. Connecting tubes longer than copulatory ducts, converging postero-medially, located between glandular appendages and spermathecae. Spermathecae slightly expanded, separated by less width of septum, directed medially. Fertilization duct short, directed anteriorly.
