( Figures 13–15 View FIGURE 13 View FIGURE 14 View FIGURE 15 )

Type material. Holotype: male ( IZCAS Ar-25026), China: Yunnan Province, Mengla County, Menglun Town, XTBG, primary tropical seasonal rainforest (21º55.035′N, 101º16.500′E, Alt: 558 m), fogging, 22 July 2007, leg. G. Z hen g. Paratypes: 1 female, 2 males ( IZCAS Ar-25027), same data as holotype; 3 males ( IZCAS Ar-25028), fogging, secondary tropical seasonal moist forest (21º54.607′N, 101º17. 005′E, Alt: 633 m), 28 July 2007, leg. G. Zheng; 1 female ( IZCAS Ar-25029), searching; 2 females, 1 male ( IZCAS Ar-25031), fogging, secondary tropical seasonal moist forest (21º54.390′N, 101º16. 811′E, Alt: 612 m), 10 August 2007; 1 female ( IZCAS Ar-25032), fogging, secondary tropical seasonal moist forest (21º54.948′N, 101º16. 982′E, Alt: 656 m), 10 August 2007.

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 View FIGURE 11 H and Baehr et al. 2013: Fig. 26E), by the shape of the distal part of male palpal bulb (compare Fig. 15 View FIGURE 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 View FIGURE 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 View FIGURE 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 View FIGURE 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 View FIGURE 13 F). Anterior end of endites with a small, sharply pointed projection ( Fig. 13 View FIGURE 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 View FIGURE 13 I), scutum not extending far dorsal of pedicel. Sperm pore small, transverse; posterior spiracles connected by groove ( Fig. 13 View FIGURE 13 H); posteriorly directed apodemes present. Palp ( Fig. 15 View FIGURE 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 View FIGURE 14 A–C. Body length 1.55; carapace 0.57 long, 0.48 wide; abdomen 0.95 long, 0.63 wide ( Fig. 14 View FIGURE 14 D, E). Endites without projections ( Fig. 14 View FIGURE 14 F). Genitalia ( Fig. 15 View FIGURE 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.
