Description of Female. Fully winged; length 4.5 mm. Head black, except mandible testaceous; antenna brown, except ventral side of segment 1 and segments 5–6 testaceous; mesosoma and metasoma black; legs testaceous, except mesotibia and mesotarsus brown; occasionally legs black, except trochanters and protarsi testaceous. Antenna clavate; antennal segments in following proportions: 28:10:18:11:10:10:10:9:9:14. Head shiny, flat, completely reticulate rugose; frontal line slightly visible; face with two lateral longitudinal keels near orbits directed towards antennal toruli; POL = 9; OL = 4; OOL = 9; OPL = 13; TL = 10; occipital carina complete. Pronotum hairy, shiny, strongly sculptured by transverse keels, except for short smooth area near scutum; pronotal tubercle reaching tegula. Scutum shiny, sculptured by irregular keels, except anterior half of median area smooth, punctate and unsculptured among punctures. Notauli incomplete, reaching approximately 0.5 length of scutum. Scutellum shiny, smooth, punctate, unsculptured among punctures. Metanotum shiny, sculptured by longitudinal keels. Propodeum reticulate rugose, with strong transverse keel between dorsal and posterior surface; posterior surface without longitudinal keels. Fore wing with one dark transverse band beneath pterostigma; distal part of stigmal vein much shorter than proximal part (4:8). Protarsal segments in following proportions: 10:5:8:20:48. Enlarged claw ( Plate 32B ) with proximal prominence bearing one long bristle. Segment 5 of protarsus ( Plate 32B ) with some rows of about 50 lamellae extending continuously to distal apex. Tibial spurs 1/1/2.

Description of Male. Fully winged; length 3.0– 3.3 mm. Head black, except mandible testaceous; antenna testaceous, except segments 4–10 dark; mesosoma and metasoma black; legs testaceous, except coxae partly black. Antenna hairy, filiform; antennal segments in following proportions: 15:8:8:8:8:8:8:8:8:11. Head shiny, completely reticulate rugose; frontal line complete; POL = 9; OL = 8; OOL = 8; OPL = 7; TL = 4; occipital carina complete. Scutum, scutellum and metanotum shiny, punctate, unsculptured among punctures. Notauli incomplete, reaching approximately 0.5 length of scutum. Propodeum reticulate rugose, with strong transverse keel between dorsal and posterior surface; posterior surface reticulate rugose, without longitudinal keels; in specimen from Indonesia, near Tubang, posterior surface partly smooth, shiny, unsculptured. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein shorter than proximal part (4:12). Parameres ( Plate 32C ) without distal inner process. Tibial spurs 1/1/2.
