Redescription.

Head without occipital carina. Gena without hollow at mouth corner; gena lamina absent. Lower margin of clypeus protruding and emarginate in the middle; tentorial pits indistinct (Fig. 11 ). Antennal formula 11354; anelli small, F1-F6 transverse, antennal clava not large, micropilosity area small and occupies the lower part of 2 last claval segments (Fig. 11 ). Antennal toruli situated above level of lower edges of eyes., Right mandible with 3 teeth, left with 4 teeth.

Mesosoma moderately depressed (Fig. 8 ). Pronotum little narrower than mesoscutum, with collar margin carinate. Notauli complete and shallow (Fig. 10 ). Scutellum depressed, without conspicuous sublateral grooves, with distinct reticulate frenal area, but without frenal groove. Metapleuron entirely reticulate (Fig. 8 ). Propodeum without plicae, costula and median carina; nucha subglobose and reticulate; propodeal spiracles near to front margin of sclerite (Fig. 10 ). Prepectus distinct, triangular, shorter than tegula. Fore wing hyaline, without speculum; M widened proximally and tapering in distal part; M much longer than S (Fig. 12 ). Hind coxa dorsally bare; hind tibia with one spur.

Metasoma on distinct transverse petiole. Metasoma short ovate, flattened laterally, shorter than combined length of mesosoma and head (Fig. 8 ); Mt2 and Mt3 large, hind margin Mt2 arched in middle (Fig. 10 ). Cerci with setae subequal in length. Hypopygium situated at 0.6 length of metasoma. Ovipositor not much protruding.
