Etymology. This species is named for Guo Zheng, who collected specimens of this species.

Diagnosis. The new species is similar to O. striata Baehr, 2013, but can be distinguished by the scuto-pedicel region without the additional median scutal ridge (compare Fig. 11 H and Baehr et al. 2013: Fig. 26E), by the shape of the distal part of male palpal bulb (compare Fig. 15 B and Baehr et al. 2013: Fig. 25J), and by the small postgynum depression of female genital area.

Description. Male (holotype). Yellowish brown species with yellow legs. Body length 1.41; carapace 0.56 long, 0.46 wide; abdomen 0.78 long, 0.51 wide. Habitus as in Fig. 13 A–C. Carapace: oval in dorsal view, sides with longitudinal streaks; dorsal area smooth with some hairs at lateral edges; pars cephalica slightly elevated in lateral view (Fig. 13 E); lateral margin rebordered. Eyes: six, well developed, ALE largest, PLE smallest; posterior eye row straight from above, procurved from front; ALE separated by less than their radius, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Clypeus margin unmodified; clypeus height about 1.0 time ALE diameter (Fig. 13 G). Sternum longer than wide, uniform, fused to carapace; radial furrows present between coxae I-II, II-III, III-IV, with rows of small pits; surface smooth, without pits, microsculpture only in furrows (Fig. 13 F). Anterior end of endites with a small, sharply pointed projection (Fig. 13 F). Legs short, thick and spineless. Abdomen: dorsal scutum strongly sclerotized, punctate, covering full length of abdomen. Book lung covers small, ovoid, without setae. Pedicel tube short, ribbed, with small, dorsolateral, triangular extensions, scuto-pedicel region lower than diameter of pedicel, with paired curved scutal ridges (Fig. 13 I), scutum not extending far dorsal of pedicel. Sperm pore small, transverse; posterior spiracles connected by groove (Fig. 13 H); posteriorly directed apodemes present. Palp (Fig. 15 A, B, E–H): patella 0.24 long, 0.14 wide, attached to femur at 0.46; cymbium completely fused to bulb, no seam visible; bulb slightly bulging ventrally, distal part with two outgrowths.

Female. As in male except as noted. Habitus as in Fig. 14 A–C. Body length 1.55; carapace 0.57 long, 0.48 wide; abdomen 0.95 long, 0.63 wide (Fig. 14 D, E). Endites without projections (Fig. 14 F). Genitalia (Fig. 15 C, D, I, J): central part of the anterior scutal ridge (asr) of postgynum with a small round projection (srp); paddle-like sclerite (pls) with thin straight arms bent at end; nail-like process (nlp) well separated; globular appendix (ga) small.
