The specific name refers to the type locality, Xiaoxi Forest Farm; adjective.
Differential diagnosis.
The female of this species differs from these of O. fujiana and O. taiwanica (Hayashi & Yoshida, 1993) by the chelicerae with three retromarginal teeth (Fig. 21B View Figure 21 ) (vs. five in O. fujiana and two, three or four in O. taiwanica ) and the broad spermathecae medially with indistinct curved (Fig. 21D View Figure 21 ) (vs. the thin connecting tubes in O. fujiana and O. taiwanica , medially with distinct curve in O. taiwanica ). Male unknown.
Description.
Female. Habitus as in Fig. 21A, B View Figure 21 . Total length 4.79, carapace 1.97 long, 1.68 wide. Eye sizes and interdistances: AME 0.12, ALE 0.12, PME 0.10, PLE 0.12; ALE-AME 0.03, AME-AME 0.06, PLE-PME 0.07, PME-PME 0.12, ALE-ALE 0.36, PLE-PLE 0.45, ALE-PLE 0.12, AME-PME 0.10, ALE-PME 0.15. MOA 0.31 long, front width 0.30, back width 0.32. Chelicerae (Fig. 21A, B View Figure 21 ) with three promarginal (middle largest, distal smallest) and three retromarginal teeth (distal largest, proximal smallest). Sternum (Fig. 21B View Figure 21 ), posteriorly proper blunt. Abdomen (Fig. 21A, B View Figure 21 ) 2.69 long, 1.91 wide. Sternum longer than wide. Leg measurements: I 10.15 (2.41, 0.71, 3.12, 2.22, 1.63); II 7.95 (2.05, 0.63, 2.43, 1.63, 1.21); III 6.70 (1.76, 0.61, 1.58, 1.73, 1.02); IV broken. Leg spination: femora I-IV with one dorsal spine each; femora I pv111111, II pv11111; patella I rv1; tibiae I v2222222222, II v22222222; metatarsi I v2222, II pv1222.
Colouration (Fig. 21A, B View Figure 21 ). 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 View Figure 21 ). Epigynal plate sub-square, anterolaterally with pair of crescent-shaped copulatory openings, medially with broad bar-shaped median septum, copulatory ducts and connecting tubes distinctly visible through integument in intact epigyne. Copulatory ducts broad, curved, posteriorly with pair of large, oval, transparent bursae. Glandular appendages relatively long, located on the anterior of connecting tubes. Connecting tube very short, posteriorly almost fused with spermathecae. Spermathecae broad, slightly separated at their apex. Fertilisation duct short, directed antero-laterally.
