Description. Male (Fig. 5 A). Total length 2.44 – 2.82 (n = 11). Holotype: body 2.69 long; carapace 1.34 long, 1.17 wide; abdomen 1.37 long, 0.90 wide. Carapace dark brown. Eyes sizes and interdistances: AME 0.07, ALE 0.09, PME 0.07, PLE 0.08; AME – AME 0.04, AME – ALE 0.02, PME – PME 0.12, PME – PLE 0.05. MOA 0.22 long, front 0.18 wide, back 0.27 wide. Clypeus 0.10 high. Cheliceral promargin with three well-separated teeth, retromargin with six teeth close to each other. Labium and gnathocoxae yellow. Legs light yellow. Leg measurements: leg I 4.57 (1.16, 0.32, 1.42, 1.13, 0.54), II 3.76 (1.04, 0.33, 1.05, 0.86, 0.48), III 3.21 (0.91, 0.29, 0.64, 0.88, 0.49), IV 4.85 (1.29, 0.38, 1.07, 1.37, 0.74). Abdomen dark grey, anterior half with a grey, dorsal scutum, occupying nearly 1 / 5 of abdomen length; posterior half with five bright chevron-shaped markings dorsally. Venter yellowish brown. Palp (Figs 5 E – G, 6 A – C): RTA with wide base extending dorsally, tip finger-shaped. E short, sickle-shaped, tip pointed, with a membranous part retrolaterally. SD relatively thick, sclerotized. TA small, with sharp tip, originating antero-retrolaterally. Tegulum widest in middle part, its posterior margin almost reaching ventral apex of tibia retrolaterally. Female (Fig. 5 B). Total length 2.67 – 3.26 (n = 8). One paratype: body 2.98 long; carapace 1.39 long, 1.29 wide; abdomen 1.63 long, 1.08 wide. Carapace dark brown anteriorly. Eyes sizes and interdistances: AME 0.06, ALE 0.09, PME 0.08, PLE 0.08; AME – AME 0.04, AME – ALE 0.01, PME – PME 0.11, PME – PLE 0.05. MOA 0.24 long, front 0.21 wide, back 0.28 wide. Clypeus 0.10 high. Leg measurements: I 5.00 (1.28, 0.36, 1.58, 1.23, 0.55); II 4.33 (1.14, 0.38, 1.17, 1.08, 0.56); III 3.49 (0.89, 0.32, 0.76, 0.98, 0.54); IV 5.24 (1.36, 0.38, 1.22, 1.49, 0.79). Abdomen dark grey, without dorsal scutum dorsally, markings as in male. Epigyne (Figs 5 C – D, 6 D – E): CO small, located in oval concavity. CD thick, anteriorly connected to two large transparent BU, with sclerotized “ bubbles ” interpreted as remnants of fused furrows. SP oval, located posteriorly, close to each other. FD originating anteriorly from SP. Epigyne butterfly-shaped ventrally.
diagnosis
Diagnosis. The new species is similar to O. komurai (Kamura 2005: 90, figs 7 – 11), but can be distinguished by: 1) sickle-shaped E (hook-shaped E in O. komurai); 2) sclerotized “ bubbles ” interpreted to be remnants of fused furrows near the FD (absent in O. komurai); 3) epigastric furrow with a bulge in the new species (absent in O. komurai); 4) MP absent (present in O. komurai).
distribution
Distribution. Known only from the type locality, Guizhou, China (Fig. 18).
etymology
Etymology. The species name is derived from the Latin word ‘ papilion ’, and refers to the butterfly-shaped epigyne; noun.
