Morphology

Head ( Figure 6B, 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 with narrowly rounded angle, LC 0.8 times as WCB; median carina complete, extending back into frons and straight in full face view, lateral lobes inconspicuous. Malar space granulate with groove, some punctures. Gena mainly smooth with fine punctures except anterior onethird weakly coriaceous. Antenna long, surpassing posterior margin of pronotal disc; scape, pedicel, flagellomere I–III, and XI in ratio of 3.1: 1.0: 1.4: 1.1: 1.2: 1.2 in length and 2.8, 1.5, 2.0, 1.4, 1.4, 2.0 times as long as wide, respectively; flagellar with dense, subappressed, and short pubescence without erect hairs. Antennal scrobe carinate. Compound eye protuberant with sparse erect short hairs. Frons coriaceous with large, shallow punctures, 0.04 mm wide. LE 1.5 times as long as OOL. WF 3.5 times as wide as WOT. WF 1.4 times as long as LE. 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 2.5 times as wide as DAO. Vertex crest broadly rounded. Temple profile distally convergent in dorsal view, with corner convex. Occipital carina absent. WG 1.0 times as wide as LAntI. Ventral surface of head weakly coriaceous with punctures as frons and vertex; median suture present.

Mesosoma ( Figure 6 C–E, G)

Pronotal disc short, 0.4 times as long as wide; pronotal collar coriaceous, short, transversely narrow, longest in middle, narrowing to sides; propleuron elongate anteriorly, outwardly developed, visible in dorsal view; disc weakly coriaceous with anterior three–quarters papillate, unpunctate; lateral margin to anterior corner with granules; posterior one-third concave, posterolateral corner angulated; posterior margin broadly concave. Mesoscutum weakly coriaceous with punctures as frons; median area elevated; parapsidal furrow short, presented one-third distally; one pair of longitudinal carina slightly overlapping parapsidal furrow; lateral margin divergent anteriorly. Scutellum elevated, 1.8 times as wide as long, polished with few fine punctures; anterior margin weakly coriaceous; scutellar pit oval, each pit distant from another by 5.0 times maximum diameter; scutellar groove with indistinct longitudinal carinae. Metanotum narrow medially, median region not elevated. Propodeal disc short, 0.5 times as long as wide; three discal carinae present, reaching transverse carina; sublateral carina absent; lateral carina present, anterior half parallel, posterior half convergent; posterior carina present, slightly concave with obtuse angle medially; basal triangle area not elevated; submedian area rugose, not depressed; sublateral area strigose; posterior margin with distinct transverse groove along with posterior carina. Lateral surface of propodeum finely strigose; transverse carina present at dorsal one-third; dorsolateral surface confused rugose. Propodeal declivity completely coriaceous without median carina; lateral and lower carina conspicuous. Mesopleuron with subtegular fovea large, connecting posterior groove; dentate process developed, sharply projected; mesopleural fovea small, deep, oval; around mesopleural fovea and anterior two-thirds of lateral surface roughly granulate to rugose; posterior one-third of lateral surface distinctly polished, smooth, weakly coriaceous. Fore wing with areolet; Rs vein 2.1 times as long as M vein; prestigma continuous to stigma; posterior stigmal margin slightly convex; 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 one-third weakly coriaceous, posterior two-thirds smooth with sparse fine punctures. Sternites II, VI papillate. Sternites III–V smooth with foveolate-puncticulate.

Distribution

Cambodia, Thailand.

Etymology

The specific Latin name refers to the extended clypeal lobe apically.

Remarks

This species similar to O. cirphi Kurian from India by having legs testaceous; head with large, shallow punctures; frontal angle of ocelli right; dentate process on mesopleuron developed; vertex crest concave; forewing with closed areolet. However, O. prolatus sp. nov. can be distinguished from O. cirphi Kurian by having gena 0.5 times as wide as LE (0.3 times as wide as in O. cirphi ); compound eye with sparse erect hairs (absent in O. cirphi Kurian ); width of gena 2.0 times as wide as LE (3.0 times in O. cirphi ).
