Redescription:

Female.

Micropterous ( Figs 40, 41 ), with forewing much reduced, approximately as long as scutellum, reaching transverse furrow behind scutellum ( Fig. 40 ); length 3.2–4.0 mm. Head black, except mandible testaceous and gena, clypeus and frontal longitudinal median area yellowish (occasionally only anterior margin of face near clypeus yellowish); antenna brown, except segments 1–2 partly testaceous; mesosoma black, except posterior collar and lateral margins of pronotum testaceous; tegula testaceous; metasoma brown­reddish; legs brown, except trochanters, articulations and tarsi testaceous. Antenna clavate; antennal segments in the following proportions: 8:5:13:9:8:7:5:6:5:9. Head shiny, slightly punctate, unsculptured among punctae; mandible with four teeth progressing larger from anterior one to posterior; occipital carina complete; face usually with long longitudinal median furrow from anterior ocellus to clypeus (occasionally furrow reduced to small impression); POL =3.5; OOL=9; OPL =5; TL =8. Pronotum shiny, smooth, with sides finely punctate; anterior disc of pronotum overly long and humped; posterior transverse impression separating disc from posterior collar narrower than disc; posterior margin of collar almost straight, reaching tegulae, without posterior lobes directed towards tegulae. Scutum hollow, rugose, much reduced, approximately as long as posterior collar of pronotum. Scutellum shiny, smooth, humped, unsculptured, approximately as long and as broad as scutum. Metanotum not visible. Metathorax + propodeum humped, separated from scutellum by transverse hollow impression, transversely carinate; anterior surface of metathorax + propodeum shiny, smooth, unsculptured; posterior surface of metathorax + propodeum dull, reticulate rugose. Meso­metapleural suture distinct, strong, complete. Mesopleuron and metapleuron dull, granulated, with fine transverse keels. Protarsal segments in following proportions: 9:2:5:12:21. Segment 2 of protarsus produced into small hook. Enlarged claw ( Fig. 3 ) with two bristles situated further distally than proximal prominence. Segment 5 of protarsus ( Fig. 3 ) with one row of about 33 lamellae; distal apex with approximately three lamellae. Tibial spurs 1/1/2.
