Sperm duct (SD) O-shaped in ventral view, reaching medial part of tegulum. Retrolateral tegular apophysis (rTA) clavate, thick, directed retrolaterally. Distal tegular apophysis (dTA) sub-triangular, anterior part broader than posterior, membranous, arising from base of embolus and retrolateral part of sperm duct.

Epigyne (Fig. 2 C and D and Fig. 3 G and H). Epigynal plate trident-like through integument, median septum (MS) sub-rectangular, anterior part slightly broader than posterior. Copulatory openings (CO) anteromedially located, oval, separated by almost the width of median septum. Posterior plate (PP) slightly sclerotised, medially concaved, covering spermathecae. Copulatory ducts (CD) relatively broad, posteriorly with pair of bursae laterally. Bursae (Bu) large, soybean-shaped, transparent, slightly touching, nearly covering 2 / 3 of valvae, with a slightly sclerotised base. Glandular appendages (GA) very short, indistinct in ventral view, mastoid-like through integument in ventral view, located on posterior of copulatory ducts. Connecting tubes (CT) thin, convergent from medio-lateral to subposteromedial part of vulva. Spermathecae (Spe) globular, slightly separated. Fertilisation ducts (FD) short, with a small spherical base, located at anterior of spermathecae, directed anterolaterally.
Diagnosis
The male of the new species is similar to Otacilia guizhumao Liu & Li, 2022 in having a hook-shaped embolus and a thick, clavate retrolateral tegular apophysis (see Liu et al. (2022): 354, Suppl. 2: 54, fig. 82), but can be separated from it by the carapace with broad dark yellow mottled markings radially along mid-line (vs. dark brown markings radially on the surface) (cf. Fig. 1 A and Liu et al. (2022): fig. 82 A), the thick (vs. moderate) and very strong (vs. moderate) bending retrolateral tibial apophysis (cf. Fig. 1 E and Liu et al. (2022): fig. 82 E) and the subtriangular distal tegular apophysis (vs. oval) (cf. Fig. 1 D and Liu et al. (2022): fig. 82 D). The females resemble that of O. guizhumao in having the oval copulatory openings, the large, soybean-shaped, slightly separated bursae nearly covering 2 / 3 of vulvae, the thin convergent connecting tubes and the globular, slightly separated spermathecae (see Liu et al. (2022): 354, Suppl. 2: 54, figs. 84 C and D), but can be distinguished from it by the carapace with broad dark yellow mottled markings radially along mid-line (vs. dark brown markings radially on the surface) (cf. Fig. 2 A and Liu et al. (2022): fig. 84 A) and the relative thin median septum (vs. broad) (cf. Fig. 2 C and Liu et al. (2022): fig. 84 C).
Etymology
The species name is derived from the name of the type locality; noun in apposition.
Distribution
Known only from the type locality in Jiangxi Province, China (Fig. 5). This species has a wide distribution in Tongboshan National Nature Reserve, based on fieldwork.
Biology
It was collected from leaf litter by using the seiving method in areas of broad-leaved forests (Fig. 4 A and B) in hilly areas.
