Description of Female. Fully winged; length 2.3–3.3 mm. Head black, except mandible testaceous; antenna black; mesosoma and metasoma black; legs brown, except tarsi and articulations testaceous. Antenna short, clavate, with segment 1 approximately twice as long as 4; antennal segments in following proportions: 12.6:5:4.5:4.5:4.5:4:4:4:7. Head dull, smooth, granulated; frontal line absent; occipital carina complete; POL = 6; OL = 3; OOL = 7; OPL = 2.5; TL = 4; greatest breadth of posterior ocelli about as long as OL. Pronotum short, with posterior surface shiny, smooth, unsculptured, much shorter than scutum (3:18); pronotal tubercle reaching tegula. Scutum shiny, smooth, punctate. Notauli incomplete, reaching approximately 0.4–0.5 length of scutum. Scutellum and metanotum shiny, smooth, unsculptured. Propodeum reticulate rugose, with strong transverse keel between dorsal and posterior surface; posterior surface with two longitudinal keels and median area very shiny, almost completely smooth and slightly rugose. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein shorter than proximal part. Segment 1 of protarsus much longer than segment 4; segment 3 of protarsus produced into hook. Enlarged claw (Plate 20D) with proximal prominence bearing one long bristle. Segment 5 of protarsus (Plate 20D) with 10–13 bristles; distal apex with about four lamellae. Tibial spurs 1/1/2.
