Type material. Holotype ♂, China, Chongqing Municipality, Wanzhou Region, Wangerbao Natural Reserve, 30°39.363′N, 108°43.999′E, 19 September 2012, Luyu Wang & Xuankong Jiang leg. Paratypes: 8♂, 5♀, same data as holotype; 9♂, 10♀, same data as holotype, but collected on 15 March 2013; 1♀, Guizhou Province, Chishui City, Wuzhufeng scenic area, 28°23.448′N, 105°58.690′E, 2 October 2012, Luyu Wang leg.
Etymology. The species name is derived from the Latin word ‘ mirus ’, meaning strange, and refers to the unique structure of the epigyne; adjective.
Diagnosis. This new species is similar to O. longituba (Wang et al. 2012: 41, figs 4A–E, 5A–I), but can be distinguished by: 1) large CO, widely separated, located centrally (relative close and located posteriorly in O. longituba); 2) epigastric furrow with a medial notch (lacking a notch in O. longituba); 3) DTA long, S-shaped, with relatively sharp apex (shorter, with a blunt apex in O. longituba); 4) tegulum inflated in the new species (uninflated in O. longituba). The new species is also similar to O. simianshan (Zhou et al. 2013: 1, figs 2A–E, 3A–G), but can be distinguished by: 1) large CO, located centrally and widely separated (smaller, relatively posterior, and close to each other in O. simianshan); 2) BU hilt-like in the new species (oval in O. simianshan); 3) DTA longer in the new species (relatively short in O. simianshan).
Description. Male (Fig. 1 A). Total length 3.08–3.86 (n=8). Holotype: body 3.18 long; carapace 1.54 long, 1.31 wide; abdomen 1.52 long, 0.93 wide. Carapace light yellowish. Eyes sizes and interdistances: AME 0.07, ALE 0.09, PME 0.07, PLE 0.08; AME–AME 0.05, AME–ALE 0.02, PME–PME 0.12, PME–PLE 0.08. MOA 0.25 long, front 0.19 wide, back 0.28 wide. Clypeus 0.11 high. Cheliceral promargin with three well-separated teeth and retromargin with five teeth near each other. Labium and gnathocoxae yellow. Legs light yellow. Leg measurements: leg I 6.02 (1.64, 0.38, 1.87, 1.45, 0.68), II 4.91 (1.34, 0.35, 0.37, 1.13, 0.72), III 4.14 (1.15, 0.32, 0.89, 1.12, 0.66), IV 6.47 (1.84, 0.38, 1.64, 1.75, 0.86). Abdomen light grey, anterior half with a small, grey dorsal scutum, occupying nearly 1/10 of abdomen length; posterior half light grey with five bright chevron-shaped markings dorsally. Venter light yellow.
Palp (Figs 1 E–H, 2A–C): DTA long, relatively curved, S-shaped, extending along the cymbium retrolaterally, its tip tapering. E gradually tapering, needle-like, tegulum membranous near base of E, without PEA. SD very short, strongly sclerotized.
Female (Fig. 1 B). Total length 3.44–4.12 (n=6). One paratype: body 3.54 long; carapace 1.65 long, 1.46 wide; abdomen 1.88 long, 1.11 wide. Carapace light yellowish anteriorly. Eyes sizes and interdistances: AME 0.08, ALE 0.09, PME 0.07, PLE 0.08; AME–AME 0.05, AME–ALE 0.02, PME–PME 0.12, PME–PLE 0.07. MOA 0.26 long, front 0.21 wide, back 0.29 wide. Clypeus 0.12 high.
