Redescription:

Female.

Macropterous; length 5.0– 5.6 mm. Testaceous­reddish, except ocellar triangle black, petiole black, metasoma partly brown and antennal segments 8–10 darkened. Antenna clavate; antennal segments in the following proportions: 18:5:18:10:8:8:9:9:9:11. Head shiny, strongly reticulate rugose; frontal line present; ocellar triangle convex, with keels among ocelli; occipital carina complete; POL=5; OL =3; OOL= 10; OPL =10; TL=8. Pronotum ( Figs 9, 10 ) shiny, strongly punctate, with transverse keels, crossed by transverse impression separating anterior collar from posterior disc; lateral margins of posterior surface of pronotum sharp; pronotal tubercle reaching tegula. Scutum shiny, smooth, strongly punctate, unsculptured among punctae. Notauli incomplete, reaching approximately 0.65× length of scutum. Scutellum shiny, smooth, finely punctate, unsculptured among punctae. Metanotum shiny, smooth, unsculptured, with anterior margin strongly convex and raised into carina. Mesopleuron and metapleuron rugose, with fine keels; occasionally mesopleuron and metapleuron shiny, punctate, unsculptured among punctae; occasionally anterior half of mesopleuron quite hairy. Propodeum with dorsal surface reticulate rugose, without transverse keel between dorsal and posterior surface; posterior surface without longitudinal keels, reticulate rugose, except for central smooth area. Forewing entirely darkened, or with two dark transverse bands; distal part of stigmal vein longer than proximal part (11:7). Protarsal segments in following proportions: 10:4:6:11:26. Segment 2 of protarsus produced into hook. Enlarged claw ( Fig. 11 ) with one bristle situated further distally than proximal prominence. Segment 5 of protarsus ( Fig. 11 ) with 2–3 rows of approximately 27 lamellae (all about same length); distal apex with about six lamellae, among which one much longer than others. Tibial spurs 1/1/2.
