( Figures 4 View FIGURE 4 , 12 View FIGURE 12 C, D, I, J)

Type material. Holotype: female ( IZCAS Ar-25060), China: Yunnan Province, Mengla County, Menglun Town, XTBG, Secondary tropical montane evergreen broad-leaved forest (21º54.813′N, 101º12.634′E, Alt: 876 m), fogging, 5 August 2007, leg. G. Zheng. Paratypes: 2 females ( IZCAS Ar-25060), same data as holotype; 1 female ( IZCAS Ar-25061), same data as holotype, pitfall traps, 16–31 February 2007; 2 females ( IZCAS Ar-25062), same data as holotype, fogging, 4 August 2007; 2 females ( IZCAS Ar-25063), same data as holotype; 1 female ( IZCAS Ar-25064), same data as holotype, fogging, 6 August 2007.

Etymology. The specific name is Latin, meaning fan-shaped, referring to the short extension in female genital area ( Fig. 12 View FIGURE 12 C, I); adjective.

Diagnosis. The new species is similar to O. tuberculata Baehr, 2013 , but can be distinguished by the scutopedicel region lower than diameter of pedicel (compare Fig. 4 View FIGURE 4 H and Baehr et al. 2013: Fig. 30E) and by the middle of epigastric furrow with a fan-shaped extension (compare Fig. 12 View FIGURE 12 C and Baehr et al. 2013: Fig. 30F).

Description. Female (holotype). Yellowish brown species with pale yellow legs. Body length 1.52; carapace 0.58 long, 0.46 wide; abdomen 0.87 long, 0.56 wide. Habitus as in Fig. 4 View FIGURE 4 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. 4 View FIGURE 4 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 of the same as ALE diameter ( Fig. 4 View FIGURE 4 G). Sternum longer than wide, uniform, fused to carapace; radial furrows present between coxae I-II, II-III, III-IV; surface smooth, without pits ( Fig. 4 View FIGURE 4 F). Endites unmodified. 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. 4 View FIGURE 4 H, I), scutum not extending far dorsal of pedicel. Posterior spiracles connected by groove; posteriorly directed apodemes present. Genitalia ( Fig. 12 View FIGURE 12 C, D, I, J): middle of the epigastric furrow with short fan-shaped extension (fse); in dorsal view there is a paddle-like sclerite (pls) with thin straight arms; nail-like process (nlp) well separated; globular appendix (ga) small.
