Figs 12 A–H, 13A–E
Type material. Holotype ♂, China, Sichuan Province, Baoxing County, Fengtongzhai Town, Yanjing Village, 30°32.321′N, 102°55.273′E, 23 May 2015, Zhizhong Gao leg. Paratypes: 2♂, 1♀, same data as for holotype.
Etymology. The species name is derived from the Latin word ‘ ovatus ’, and refers to the oval, egg-shaped bursae; adjective.
Diagnosis. The new species is similar to O. pseudostella (Fu et al. 2014: 488, figs 3A–G, 4A–E), but can be distinguished from the latter by: 1) a short E (longer in O. pseudostella); 2) PEA sharp (relatively blunt in O. pseudostella); 3) oval BU located posteriorly (pear-like and located anteriorly in O. pseudostella); 4) CO located centrally in the concavity (anteriorly, concealed by the margin of concavity in O. pseudostella). The new species is also similar to O. acuta sp. nov. (Figs 14–15), but can be distinguished from the latter by: 1) bulb with a sharp PEA prolaterally, directed to 10 o’clock (pointed ventrally in O. acuta sp. nov.); 2) palpal tibia with one broad RTA (with two distinct, thin apophyses with the same length in O. acuta sp. nov.); 3) BU oval, located posteriorly (relatively round, located anteriorly in O. acuta sp. nov.).
Description. Male (Fig. 12 A). Total length 2.55–3.12 (n=3). Holotype: body 3.12 long; carapace 1.56 long, 1.37 wide; abdomen 1.52 long, 1.14 wide. Carapace yellowish brown. Eyes sizes and interdistances: AME 0.09, ALE 0.11, PME 0.07, PLE 0.09; AME–AME 0.05, AME–ALE 0.01, PME–PME 0.09, PME–PLE 0.07. MOA 0.21 long, front 0.21 wide, back 0.23 wide. Clypeus 0.08 high. Cheliceral promargin with three well-separated teeth and retromargin with two teeth close to each other. Labium and gnathocoxae brown. Legs light brown. Leg measurements: leg I 5.91 (1.78, 0.41, 1.67, 1.42, 0.63), II 4.64 (1.28, 0.42, 1.21, 1.00, 0.73), III 3.97 (1.05, 0.36, 0.89, 1.01, 0.66), IV 6.10 (1.69, 0.48, 1.47, 1.54, 0.92). Abdomen brown, anterior half with a large dorsal scutum, occupying nearly 9/10 of abdomen length; posterior half without distinct chevron-shaped markings dorsally. Venter grey.
Palp (Figs 12 A–H, 13A–E): RTA with broad base bifurcated into thumb-like tip and triangular apophysis. Cymbium ventrally with several hairs around E tip. E beak-like, prolaterally with sharp PEA. SD sclerotized. Conductor membranous, sharp, originating from E base.
Female (Fig. 12 B). Total length 3.74 (n=1). One paratype: body 3.74 long; carapace 1.68 long, 1.54 wide; abdomen 2.02 long, 1.28 wide. Carapace brown. Eyes sizes and interdistances: AME 0.10, ALE 0.11, PME 0.07, PLE 0.08; AME–AME 0.05, AME–ALE 0.02, PME–PME 0.13, PME–PLE 0.07. MOA 0.26 long, front 0.23 wide, back 0.27 wide. Clypeus 0.09 high. Leg measurements: I 6.01 (1.65, 0.49, 1.72, 1.37, 0.78); II 5.10 (1.49, 0.38, 1.29, 1.18, 0.76); III 4.45 (1.26, 0.42, 0.91, 1.19, 0.67); IV 6.59 (1.79, 0.53, 1.57, 1.81, 0.89). Abdomen dark grey dorsally, anterior half without dorsal scutum; posterior half with three chevron-shaped markings dorsally.
Epigyne (Figs 12 C–D, 13D–E): CO small, located in large, shallow concavity anteriorly (Figs 12 C, 13D), widely separated. Concavity with distinct anterior margin. CD thick and short, separated by two transparent BU, oval, located centrally; CD as long as BU. SP small, widely separated, with similar diameter to CD, located posteriorly. FD originating anteriorly from SP.
Distribution. Known only from the type locality, Sichuan, China (Fig. 18).
