Redescriptions:

Female. Macropterous; length 3.0–5.0 mm. Reddish­darkened; mandible testaceous, with teeth brown; antenna testaceous, except segments 7–10 brown; propodeum black; metasoma brown. Antenna clavate; antennal segments in the following proportions: 11:5: 11:6:6:6:6:6:5:7. Head shiny, strongly punctate, especially anterior region, unsculptured among punctae; occipital carina complete; POL =7; OL =5; OOL=9; OPL=7; TL=7. Pronotum shiny, smooth, strongly punctate, unsculptured among punctae, crossed by transverse impression separating anterior collar from posterior disc; lateral margins of posterior surface rounded; pronotal tubercle reaching tegula. Scutum shiny, smooth, finely punctate, unsculptured among punctae. Notauli incomplete, reaching approximately 0.65× length of scutum. Scutellum and metanotum shiny, smooth, finely punctate, unsculptured among punctae; anterior margin of metanotum shiny, smooth, unsculptured, with anterior margin strongly convex and raised into carina. Mesopleuron shiny, strongly punctate, with tuft of hairs on anterior third. Metapleuron partly smooth and unsculptured. Propodeum with dorsal surface reticulate rugose, without transverse keel between dorsal and posterior surface; posterior surface without longitudinal keels, reticulate rugose, except central smooth area. Forewing hyaline, with two dark transverse bands; distal part of stigmal vein longer than proximal part (14:8). Protarsal segments in following proportions: 8:3:4:8:19. Protarsus without segments produced into hook. Enlarged claw ( Fig. 16 ) with one bristle situated further distally than proximal prominence. Segment 5 of protarsus ( Fig. 16 ) with two rows of lamellae (about eight longer and 21 shorter); distal apex with about seven lamellae, among which one much longer than others. Tibial spurs 1/1/2.

Male. (tentatively associated, not reared).

Macropterous; length 2.4 mm. Head black; mandible testaceous, with teeth brown; antenna brown, except segments 1–2 or only 1 testaceous; mesosoma black; tegula testaceous; metasoma brown; legs brown, except tarsi and meso­ and metatibia testaceous; occasionally legs totally brown.Antenna filiform, with hairs at most as long as breadth of segments; antennal segments in the following proportions: 8:4:7:5:5:5:5:5:5:8. Head shiny, strongly punctate, unsculptured among punctae; frontal line incomplete, not present in front of anterior ocellus; occipital carina complete; POL=8; OL= 4; OOL=6; OPL=5; TL= 4. Scutum shiny, finely punctate, unsculptured among punctae. Notauli incomplete, reaching approximately 0.5–0.6× length of scutum. Scutellum shiny, punctate, unsculpured among punctae. Metanotum shiny, smooth, finely punctate, unsculptured among punctae. Propodeum dull, reticulate rugose, without transverse keel between dorsal and posterior surface; posterior surface completely reticulate rugose, or with more or less large central smooth area, occasionally situated near distal extremity. Forewing hyaline, without dark transverse bands; distal part of stigmal vein slightly longer than proximal part (10:9). Paramere ( Fig. 17 ) about as long as penis, with large hatchet blade distal branch wrapping penis, without dorsal proximal membranous process. Tibial spurs 1/1/2.
