Morphology

Head ( Figure 2B, F ). Wider than long, 0.9 times as long as wide. Mandible with four apical teeth, uppermost one smallest, following two of same size, lowermost one sharpest and downward pointing. Clypeus coriaceous; median lobe narrowly rounded, LC 0.6 times as long as WCB; median carina complete, extending back into frons and straight in full face view, lateral lobes smooth, inconspicuous. Malar groove present. Antenna short, not surpassing posterior margin of pronotal disc; scape, pedicel, flagellomere I–III, and XI in ratio of 2.4: 1.1: 1.4: 1.1: 1.0: 1.2 in length and 2.3, 1.7, 1.9, 1.6, 1.3 and 2.4 times as long as wide, respectively; flagellar with dense, subappressed, and short pubescence without distinct erect setae. Antennal scrobe carinate. Compound eye protuberant with sparse short hairs. Frons coriaceous with large, shallow punctures, up to 0.03 mm wide. LE 1.5 times as long as OOL. WF 4.0 times as wide as WOT. WF 1.3 times as long as LE. WH 1.6 times as wide as WF. Ocelli small, anterior ocellus completely surpassing imaginary to eye line; frontal angle of ocellar triangle right; distance from posterior ocelli to vertex crest 2.0 times as wide as DAO. Vertex crest broadly concave. Temple profile distally convergent in dorsal view, with corner convex. Occipital carina absent. WG 1.1 times as wide LAntI. Ventral surface of head coriaceous with punctures as frons and vertex; median suture present.

Mesosoma ( Figure 2 C–E, G)

Pronotal disc 0.4 times as long as wide; pronotal collar short, transversely narrow, longest in middle, narrowing to sides; disc coriaceous, papillate; lateral margin to anterolateral margin with granules; posterior margin straight. Mesoscutum granulate with punctures as frons; parapsidal furrow complete, conspicuous; lateral margin parallel. Scutellum polished weakly coriaceous with fewer punctures than frons and mesoscutum; scutellar pit oval, each pit distant from another by 2.5 times the maximum diameter; scutellar groove with indistinct longitudinal carinae. Metanotum narrow medially, median region not elevate. Propodeal disc short, 0.5 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, slightly angulate medially; basal triangle area not elevate; submedian area rugose, not depressed; sublateral area strigose; posterior margin without distinct transverse groove. Lateral surface of propodeum mainly imbricate, dorsal and anterior area rugulose. Propodeal declivity completely imbricate without median carina; lateral and lower carina conspicuous. Mesopleuron with subtegular groove thin; dentate process probuberant; mesopleural fovea large, deep, circular; anterior half with granules, posterior half coriaceous. Fore wing without closed areolet; Rs vein 1.5 times as long as M vein; prestigma continuous to stigma; posterior stigmal margin straight; 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. Sternites II and VI papillate.

Distribution

Cambodia.

Etymology

The specific name refers to the name of type locality, Cardamom Forest in Cambodia .

Remarks

This species is similar to O. ventralis Krombein from Sri Lanka by having antennal scrobe carinate; frons with large, shallow punctures; propodeal disc with three discal carinae, reaching transverse carina; dentate process on mesopleuron probuberant; sternites II and VI papillate. However, O. cardamomensis sp. nov. can be distinguished from O. ventralis by vertex crest broadly concave (straight in O. ventralis ); frontal angle of ocelli right (acute in O. ventralis ); OOL 1.8 times as wide as WOT (1.3 times in O. ventralis ); having rs vein + M vein without apical stub (with short stub in O. ventralis ).
