Description of Female. Fully winged; length 3.0– 4.7 mm. Head black, except mandible testaceous; antenna testaceous, except segments 4–10 brown; mesosoma and metasoma black; legs testaceous, occasionally darkened. Antenna clavate; antennal segments in following proportions: 9:5:6:4.5:5:5:5:5:5:7. Head shiny, hairy, completely reticulate rugose; frontal line present, but hardly visible; occipital carina complete; POL = 6; OL = 4; OOL = 5; OPL = 5; TL = 3. Pronotum dull, hairy, completely reticulate rugose, approximately twice as broad as long; posterior surface shorter than scutum (5:13); pronotal tubercle reaching tegula. Scutum shiny, smooth, strongly punctate, with punctures very broad, similar to areolae, unsculptured among punctures; occasionally scutum finely punctate (in specimens from China, Taiwan, Sungkang, and China, Mt. Baishanzu). Notauli incomplete, reaching approximately 0.3 length of scutum; in specimens from Taiwan, Sungkang, notauli slightly visible near anterior margin of scutum. Scutellum as sculptured as scutum. Metanotum shiny, smooth, unsculptured, with some areolae near anterior margin. Propodeum with strong transverse keel between dorsal and posterior surface; dorsal surface reticulate rugose; posterior surface with two complete longitudinal keels, lateral areas rugose and median area rugose and with some transverse keels. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein much shorter than proximal part (5:18). Protarsal segments in following proportions: 50:11:10:16:45. Enlarged claw ( Plate 47C ) with proximal prominence bearing one long bristle. Segment 5 of protarsus ( Plate 47C ) with basal part longer than distal part (37:8), with one row of about 2–8 lamellae; distal apex with two lamellae. Tibial spurs 1/1/2.

Description of Male. Fully winged; length 1.7–2.9 mm. Head black, except mandible testaceous; antenna usually testaceous; occasionally antenna brown, except segment 1 testaceous; mesosoma and metasoma black; legs testaceous, except proximal region of metacoxa black; occasionally legs brown. Antenna filiform; antennal segments in following proportions: 10:7:6:5:5:5:5:4:5:9. Head shiny or dull, completely reticulate rugose, or granulated and rugose; frontal line complete; face with two lateral longitudinal keels near orbits directed towards antennal toruli; POL = 7; OL = 4; OOL = 7; OPL = 4; TL = 4; occipital carina complete. Scutum, scutellum and metanotum shiny, slightly punctate, unsculptured among punctures. Notauli incomplete, reaching approximately 0.3–0.4 length of scutum. Propodeum with strong transverse keel between dorsal and posterior surface; dorsal surface reticulate rugose; posterior surface with two complete longitudinal keels and median area as rugose as lateral areas; occasionally posterior surface without longitudinal keels, or with two very slight (almost invisible) longitudinal keels. In specimen from Brunei, 04°34'N 115°07'E, posterior surface of propodeum without longitudinal keels and with central area shiny, smooth and unsculptured. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein shorter than proximal part (3.5:9). Paramere much shorter than penis (Plate 48A) or about as long as penis, without distal inner process, without or with proximal membranous process; in specimen from China, Shanghe County, inner side of paramere with numerous folds (Plate 48B). Tibial spurs 1/1/2.
