Etymology.

The specific name refers to the type locality, Ziyaoshan; adjective.

Diagnosis.

The female of this species is similar to Otacilia acutangula Liu, 2020 and O. macrospora Fu, Zhang & Zhang, 2016 in having a M-shaped epigynal margin and concave anterior epigynal part (see Liu et al. 2020: 13, fig. 8C, D; Fu et al. 2016: 138, fig. 20, 21), but can be separated from them by the chelicerae with three retromarginal teeth (Fig. 21B) (vs. five in O. acutangula and O. macrospora) and the widely separated spermathecae (Fig. 21D) (vs. slightly separated in O. acutangula and O. macrospora).

Female. Habitus as in Fig. 21A, B. Total length 3.45, carapace 1.60 long, 1.31 wide. Eye sizes and interdistances: AME 0.1, ALE 0.08, PME 0.06, PLE 0.08, AME-AME 0.05, AME-ALE 0.02, PME-PME 0.12, PME-PLE 0.06, AME-PME 0.08, AME-PLE 0.16, ALE-ALE 0.25, PLE-PLE 0.37, ALE-PLE 0.1. MOA 0.23 long, frontal width 0.23, posterior width 0.25. Chelicerae (Fig. 21A, B) with three promarginal (proximal largest, distal smallest) and three retromarginal teeth (distal largest, third smallest). Sternum (Fig. 21B), posteriorly proper blunt. Pedicel 0.14 long. Abdomen (Fig. 18A, B) 1.73 long, 1.20 wide. Leg measurements: I 6.20 (1.41, 0.57, 1.96, 1.50, 0.76); II 4.98 (1.07, 0.55, 1.51, 1.10, 0.75); III 4.39 (1.17, 0.39, 0.97, 1.17, 0.69); IV 6.63 (1.76, 0.59, 1.68, 1.64, 0.96). Leg spination (Fig. 18A, B): femora I-IV with 1 dorsal spine each; femora I p11111, p1111 (right), II p11; tibiae I v22222222, II v22222222; metatarsi I v2222, II v2222.

Colouration (Fig. 21A, B). Carapace yellow, with radial, irregular dark stripes mediolaterally. Sternum yellow, with yellow-brown margin. Legs yellow, without annulations on tibiae and distal part of femora, patellae and metatarsi. Abdomen brown, with abundant yellowish spots in dorsal view.

Epigyne (Fig. 21C, D). Epigynal plate mushroom like, anteriorly with M-shaped sclerotized margin, medially with pair of slit-like copulatory openings covered by epigynal plug, posteromedially with trapezoidal median septum. Copulatory ducts, glandular appendages, connecting tubes and spermathecae distinctly visible through integument in intact epigyne. Copulatory ducts short and broad, posteriorly with pair of large, oval, transparent bursae. Glandular appendages short, located on anterior of connecting tubes, near base of bursae. Connecting tubes longer than copulatory ducts, convergent. Spermathecae slightly expanded, separated by approximately 1/2 of median septum width. Fertilization ducts short, directed antero-laterally.

Male unknown.
