Morphology

Head ( Figure 3B, F ). Wider than long, 0.9 times as long as wide. Mandible with four apical teeth, uppermost one smallest, following two same size, lowermost one largest and sharpened downward. Clypeus coriaceous; median lobe narrowly rounded; LC 0.7 times as long as WCB; median carina complete, extending back into frons and straight in full face view, lateral lobes inconspicuous. Malar space granulate with groove. Antenna short, not surpassing posterior margin of pronotal disc; scape, pedicel, flagellomere I–III, and XI in ratio of 2.6: 1.0: 1.3: 1.2: 1.0: 1.1 in length and 2.8, 1.7, 2.1, 1.5, 1.3, 2.2 times as long as wide, respectively; flagellar with dense, subappressed, short pubescence, erect hairs absent. Antennal scrobe carinate. Compound eye protuberant with sparse erect hairs. Frons coriaceous with large, shallow punctures, up to 0.02 mm wide. LE 1.5 times as long as OOL. WF 3.7 times as wide as WOT. WF 1.3 times as long as LE. WH 1.7 times as long as WF. Ocelli small, anterior ocellus completely surpassing imaginary top eye line, posterior ocelli not surpassing imaginary top eye line; frontal angle of ocellar triangle right; posterior ocelli distant from vertex crest by 2.5 times as wide as DAO. Vertex crest broadly concave. Temple profile distally convergent, corner convex in dorsal view. Occipital carina absent. WG 0.8 times as wide as LAntI. Ventral surface of head weakly coriaceous with punctures as frons and vertex; median suture present.

Mesosoma ( Figure 3 C–E, G)

Pronotal disc 0.5 times as long as wide; pronotal collar rugulose, short, transversely narrow, longest in middle, narrowing to sides; propleuron outwardly developed, visible in dorsal view; disc coriaceous with anterior half papillate; lateral margin to anterior corner with granules; posterior margin straight. Mesoscutum granulate with punctures as frons; parapsidal furrow complete, conspicuous; lateral margin divergent anteriorly. Scutellum coriaceous with punctures as mesoscutum; scutellar pit oval, each pit distant from another by 3.0 times as wide as maximum diameter; scutellar groove with three short longitudinal carinae. Metanotum narrow medially, median region not elevate. Propodeal disc short, 0.6 times as long as wide; three discal carinae present, reaching transverse carina; sublateral carina absent; lateral carina present, parallel laterally and slightly narrowing at distal one-eighth; posterior carina present, concave with obtuse angle medially; basal triangle area elevate; submedian area rugose, not depressed; sublateral area strigose; posterior margin without distinct transverse groove. Lateral surface of propodeum mainly granulate, dorsal area strigose, narrowing posteriorly. Propodeal declivity completely coriaceous without median carina; lateral and lower carina conspicuous. Mesopleuron with subtegular fovea large, connecting posterior groove; dentate process developed, projected; mesopleural fovea large, deep, oval; around mesopleural fovea and anterior half of lateral surface roughly granulate to rugose; posterior half of lateral surface distinctly polished, smooth, weakly coriaceous. Fore wing without closed areolet; M vein short, Rs vein 3.0 times as long as M vein; prestigma continuous to stigma; posterior stigmal margin slightly concave; R vein slightly curved at apex. Hind wing with five hamuli. Tibia with one tibial spur; claws bifid.

Metasoma

Petiolate. Tergite I smooth without distinct punctures. Tergites II–IV with anterior half weakly coriaceous, posterior half smooth with hairs laterally. Sternites II and VI papillate.

Distribution

Cambodia.

Etymology

The specific Latin name refers to the deeply concave crest of vertex in dorsal view.

Remarks

This species is similar to O. liukueiensis Terayama from Taiwan by having mandible and femora dark castaneous; mandible with four apical teeth; anterolateral corner of pronotal disc carinate. However, O. concavus sp. nov. can be distinguished from O. liukueiensis Terayama by tibia, tarsi yellow (dark castaneous in O. liukueiensis ); having clypeal lobe narrow (with obtuse angle in O. liukueiensis ); sternites II and VI papillate (smooth without fine punctures in O. liukueiensis ); vertex crest broadly concave (straight in O. liukueiensis ); frontal angle of ocelli right (acute in O. liukueiensis ).
