Metanotum shiny, unsculptured, not transversely striate, not hollow behind scutellum. Mesopleuron and metapleuron transversely striate. Metathorax + propodeum shiny, smooth, unsculptured, with posterior surface transversely striate. Meso-metapleural suture obsolete. Protarsal segments in following proportions: 13:2:4:13:19. Enlarged claw ( Plate 133B ) with one large subapical tooth and one row of six–seven lamellae. Segment 5 of protarsus ( Plate 133B ) with two rows of about 14–24 lamellae; distal apex with about 8–15 lamellae. Tibial spurs 1/0/1.

Description of Male. Fully winged; length 1.7 mm. Head yellow-testaceous, except an ocellar brown spot and two brown spots on temple; antenna yellow-testaceous; mesosoma yellow-testaceous; metasoma browntestaceous; legs yellow. Antenna filiform; antennal segments in following proportions: 4:4.5:8:7:7:7:6:7:6:9.5; antennal segment 3 more than four times as long as broad (8:1.5). Head shiny, finely punctate, unsculptured among punctures; frontal line absent; occipital carina absent; temple distinct; POL = 5; OL = 2; OOL = 2.5; greatest breadth of posterior ocelli about as long as OL; region between posterior ocelli and eyes with an oval shiny and smooth area. Palpal formula 5/2. Scutum shiny, finely punctate, unsculptured among punctures. Notauli complete, posteriorly joint. Scutellum and metanotum shiny, smooth, unsculptured. Propodeum with dorsal surface shiny, smooth, unsculptured, except two median parallel longitudinal keels; posterior surface dull, reticulate rugose, without longitudinal or transverse keels. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein much longer than proximal part. Dorsal process of paramere ( Plate 131C ) short and transverse, with distal apex pointed. Tibial spurs 1/1/2.
