Description

Female. Body robust, its length 6.8–9.0 mm. Fore wing length 5.4–6.5 mm.

Head 0.6 times as long as wide; clypeus 0.6–0.7 times as long as wide. Anterior tentorial pit small. Face densely punctate, slightly convex medially, 0.6–0.7 times as long as wide. MSL 0.7 times as long as BWM. Frons narrowly smooth above antennal sockets, punctate upper 0.7. OOL 1.5 times as long as OD; IOD 0.8–1.0 times as long as OD; interocellar area without pit. Vertex punctate and gena shiny and with a few punctures. Occipital carina distinct dorsally, roundly arched in dorsal part. Antenna with 40–45 flagellomeres. F 1 1.9–2.0 times longer than F 2.

Mesosoma punctate. Lateral area of pronotum largely smooth in ventral part. Distal abscissa of vein CU of hind wing present (Fig. 4 C). Anterior projection of submetapleural carina rounded at posterior angle. Posterior transverse carina, pleural carina and anterior transverse carina of propodeum complete (Fig. 4 E). Area basalis of propodeum with dense punctures (Fig. 4 E). Punctures on propodeal area superomedia as dense as on area externa and area dentipara (Fig. 4 E). Latero-median longitudinal carina on propodeum present, its part between anterior and posterior transverse carinae of propodeum weaker than part before anterior transverse carina. Latero-longitudinal carina on propodeum partly present. Hind femur 4.6–5.0 times as long as maximum width in lateral view. Hind tibia 8.2–12.6 times as long as maximum width in lateral view. Hind basitarsus 2.1–2.4 times as long as second hind tarsal segment.

Metasoma. Metasomal tergite 1 densely punctate. Metasomal tergites 2–4 densely punctate, except for posterior narrow margins (Fig. 4 F). Oblique grooves on tergites 2–3 deeply impressed (Fig. 4 F). Metasomal tergite 1 1.5–1.6 times as long as maximum width, latero-median carina present and inner area between latero-median carinae with dense punctures. Metasomal tergite 2 1.0–1.1 times as long as maximum width. Metasomal tergites 2 and 3 each without a pair of short latero-longitudinal keels. Ovipositor sheath 1.3–1.9 times as long as hind tibia.

Colour. Body (excluding wings and legs) black, except for: clypeus, mandible, except tip, ovipositor, yellowish-brown; antenna, except for yellowish-brown outer spot of scape and pedicel, dark brown; membranous part of sternites, whitish-yellow; small spot of pronotum before tegula, tegula, posterior narrow margins of tergites 2–3, brown; wings hyaline; veins and pterostigma brown. Legs: hind coxa, femur and tibia, black or blackish-brown, fore and mid-coxae whitish-yellow.

Male. Unknown.

Diagnosis

Area basalis of propodeum not narrowed posteriorly, sub-rectangular, with dense punctures (Fig. 4 E). Body robust (Fig. 4 A). Hind femur and tibia black or blackish-brown (Fig. 4 A). Oblique grooves on tergites 2–3 deeply impressed (Fig. 4 F). Body almost entirely covered with dense and coarse punctures. Antenna with 40–45 flagellomeres.

Etymology

Named after its densely punctate body: “ densus ” is Latin for dense and “ punctum ” is Latin for puncture.

Distribution

China ( Fujian).

Biology

Unknown.

Notes

This species resembles O. lota , but it can be distinguished by the following character states: hind femur and tibia black or blackish- brown (hind femur and tibia yellow, except for its brown apex and base in O. lota ); dorsal part of occipital carina almost roundly arched (dorsal part of occipital carina reverse V-shaped, strongly angled); area basalis of propodeum with dense punctures (area basalis of propodeum smooth in O. lota ); oblique grooves on tergites 2–3 deeply impressed (oblique grooves on tergites 2–3 moderately impressed in O. lota ).
