(Figs 8–12, 14)
Material examined. Holotype, ♂, pinned (deposited in SCAU), “ CHINA, Guangdong, Nanling National Nature Reserve (24°55'43"N, 113°1'1"E), 5–7.VI.2010, Zaifu Xu, No. 201301038”.
Diagnosis. This species can be distinguished from known species of genus Okinawepipona by following combination of features: body covered with very coarse punctures; mesoscutum, scutellum and metanotum strongly convex; propodeum with dorsal surface produced, posterior surface dull, rugose and forming week striae, dorsal and posterior surfaces bordered by sharp edge; tergum I in dorsal view about twice as wide as long. Metasomal terga black with wide yellow bands at apical margin of terga I and II (about 1/3 length of tergum I).
Description. Male. Body length 9.5 mm; fore wing length 10 mm. Head in frontal view about 1.2 × as wide as high (Fig. 8). Vertex without cephalic fovea. Distance from posterior ocelli to apical margin of vertex about 1.6 × distance from posterior ocelli to inner eye margin. Gena much narrower than eye, in lateral view about 0.7 × as wide as eye. Occipital carina complete, present along entire length of gena, but dorsally somewhat weak. Inner eye margins in frontal view about 1.5 × further apart from each other at vertex than at clypeus. Clypeus in frontal view about as wide as high, apical margin deeply emarginate medially, forming sharp triangle tooth on each lateral side (Fig. 8), width of emargination about 1/3 width of clypeus between inner eye margins; in lateral view disc of clypeus gradually and prominently convex to near apical margin, then slightly bent backward. Mandibular teeth quite short, with two longitudinal carinae running parallel, one of them about half as long as other (closer to mandible teeth) (Fig. 8). Antennal scape about 2.7 × as long as its maximum width; flagellomere I about 1.7 × as long as its maximum width, II–IX longer than wide, X small, as long as wide, terminal flagellomere slightly curved, slightly more than 2.5 × as long as its basal width (Fig. 9).
Mesosoma longer than wide in dorsal view. Pronotal carina slightly raised, produced at humeral angles, reaching ventral corner of pronotum. Mesoscutum strongly convex, about as long as wide between tegulae; anterior margin broadly rounded. Disc of scutellum convex, in profile not at the same level as mesoscutum (Fig. 10). Disc of metanotum angled. Propodeum excavated medially, posterior surface dull, basal fovea about 1/4 of length of median carina; medial carina developed for entire length of propodeum; dorsal surface of propodeum rugose, convex (Fig. 11); dorsal and posterior surfaces bordered by sharp edge.
Metasomal tergum I narrower than II, truncate at base (Fig. 12); anterior vertical surface of tergum I weekly convex, with some large and deep punctures, clearly separable from posterior horizontal surface, but not by carina; tergum I laterally divided by sharp carina into upper and lower parts. Tergum I in dorsal view about twice as wide as long (Fig. 12); tergum II about as wide as long; sternum II gradually and slightly convex to apical margin. Hind coxa with distinct carina, which is elevated to form triangular process.
Body covered with longer hairs and coarser punctures than those in Okinawepipona nigra sp. nov. Clypeus covered with shallow and small punctures. Frons densely covered with very coarse punctures, interspaces between punctures raised to form reticulation. Vertex and gena with punctures similar to those on frons. Pronotum with punctures coarser than punctures in vertex and gena, spaces between punctures narrow, strongly raised to form reticulation. Mesocutum densely covered with very coarse punctures. Punctures on scutellum similar to those on mesoscutum. Puncture on metanotum denser and smaller than those on scutellum. Mesepisternum with dense, and very coarse punctures posterodorsally, barely punctured anteroventrally; border between posterodorsal and anteroventral parts indistinct. Dorsal metapleuron with strong striae, area between striae smooth; ventral metapleuron with scattered shallow punctures. Propodeum with punctures on dorsal surface larger than those on mesopleuron, punctures on lateral parts shallower and arranged into weak striae, posterior surface dull, slightly rugose with weak striae. Metasomal terga I–II densely covered with coarse punctures, punctures on tergum I coarser and denser than those on tergum II, punctures on terga III–V much smaller and weaker than those on terga I–II; tergum VI with minute punctures; punctures on sternum II less coarse and smaller than those on basal half and similar to those on apical half of tergum II.
Color. Black; following parts orange-yellow: clypeus except apical margin, spot on frons between antennal sockets, mandible except margins, antennal scape beneath, narrow band along pronotal carina in dorsal part of pronotum, apical bands on metasomal terga I and II (bands incised medially), two spots laterally on apical margin of sternum II. Legs black except spots on apical margin of fore and mid femora, outer surface of fore femur and that of fore tibia basally yellow. Propodeal valvulae light brown. Wings brown, slightly infuscate, veins dark brown.
Female. Unknown.
Distribution. China (Guangdong).
Etymology. The specific name refers to the coarse (curcus in Latin) punctures in this species.
