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 View Figure 1 E and Liu et al. (2022): fig. 82 E) and the subtriangular distal tegular apophysis (vs. oval) (cf. Fig. 1 View Figure 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 View Figure 2 A and Liu et al. (2022): fig. 84 A) and the relative thin median septum (vs. broad) (cf. Fig. 2 View Figure 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 View Figure 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 View Figure 4 A and B) in hilly areas.
