Description of female ( Plate 64A ). Fully winged; length 3.3–4.2 mm. Head brown-reddish, or black-brown, or reddish, except mandible and clypeus testaceous; occasionally also gena and anterior region of face near clypeus testaceous; antenna testaceous, except segments 4–10, or 9–10, or only 10 darkened; mesosoma black or brown or reddish; metasoma brown or reddish; legs testaceous, partly whitish, mainly on dorsal side of protibia; occasionally metacoxa brownish. Antenna clavate; antennal segments in following proportions: 14:8:8:7:6:7:7:7:5:10. Head shiny, smooth, punctate, unsculptured among punctures; occasionally head more or less dull and more or less granulated; occasionally face more or less sculptured by longitudinal or transverse keels; frontal line complete; occipital carina complete; POL = 1.5; OL = 2; OOL = 7.5; OPL = 9; TL = 7. Pronotum very short, crossed by transverse furrow. Scutum, scutellum and metanotum shiny, smooth, finely punctate, unsculptured among punctures. In specimen from Malaysia, Air Hitam Forest Reserve, scutum sculptured by very weak longitudinal striae. In specimen from Borneo, 00°03'S 113°59'E, scutum completely granulated. Notauli incomplete, reaching approximately 0.4–0.7 length of scutum. Propodeum with strong transverse keel between dorsal and posterior surface, with two lateral pointed apophyses; dorsal surface reticulate rugose; posterior surface with two complete longitudinal keels and median and lateral areas sculptured by transverse keels. Fore wing with two dark transverse bands; stigmal vein with distal part about as long as proximal part. Petiole very long, much shorter than metasoma (6:21). Protarsal segments in following proportions: 15:3:2:13:15. Enlarged claw ( Plate 64B ) with one tooth and one bristle. Segment 5 of protarsus ( Plate 64B ) with one preapical lamella, two bristles and one distinct proximal prominence. Tibial spurs 1/1/2.

Description of Male. Fully winged; length 2.1–2.9 mm. Head black, except mandible, clypeus and anterior margin of face testaceous-reddish; antenna testaceous, except segments 9–10 darkened; mesosoma black; metasoma brown-testaceous; legs testaceous, except metacoxa partly brown. Antenna filiform; antennal segments in following proportions: 12:7:7:9:9:9:8:8:7.5:10. Head dull, completely reticulate rugose; frontal line complete; occipital carina complete; POL = 3.5; OL = 3.5; OOL = 7; OPL = 6; TL = 5. Scutum dull, rugose and sculptured by irregular keels. Notauli almost complete, indistinct near posterior margin of scutum. Scutellum and metanotum shiny, smooth, finely punctate, unsculptured among punctures. Propodeum reticulate rugose, with areolae very large and with two lateral pointed apophyses; posterior surface with median area as rugose as lateral areas. In specimen from Malaysia, Pasoh Forest Reserve, median area of posterior surface of propodeum partly shiny and smooth. Fore wing with two dark transverse bands; stigmal vein strongly curved, with distal part shorter than proximal part (17:20). Petiole very long, shorter than metasoma (11:45). Genitalia in plate 63E. Tibial spurs 1/1/2.
