Etymology
Etymology. The species name is derived from the Latin word ‘ papilion ’, and refers to the butterfly-shaped epigyne; noun.
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).
Description
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.
