Description.

Holotype, ♀, length of body 2.3 mm, of fore wing 2.5 mm.

Head. Antenna with 25 segments and 1.1 times as long as fore wing; third segment 1.1 times as long as fourth segment, length of third, fourth and penultimate segments 2.7, 2.5 and 1.8 times their width, respectively (Figs 423, 428); length of maxillary palp unknown, palp submerged in glue; occipital carina widely removed from hypostomal carina and dorsally absent; hypostomal carina narrow; length of eye in dorsal view 3.3 times temple; temples directly narrowed (Fig. 420) and largely smooth; vertex finely punctate, with interspaces mostly wider than punctures; frons slightly depressed behind antennal sockets and with some curved rugulae, remainder slightly convex and setose, largely finely punctate, with interspaces wider than punctures; face medio-dorsally elevated, coarsely punctate, with interspaces slightly wider than punctures and some striae latero-dorsally; width of clypeus 2.8 times its maximum height and 0.6 times width of face (Fig. 424); clypeus flat, smooth and its ventral margin rather thin and medially straight; hypoclypeal depression wide and deep (Fig. 424); labrum flat (including ventral rim); malar suture complete; with punctures between malar suture and clypeus; length of malar space 1.5 times basal width of mandible (Fig. 425); mandible strongly constricted and twisted apically, without distinct ventral carina, second tooth medium-sized.

Mesosoma. Length of mesosoma 1.3 times its height; dorsal pronope absent, pronotum short and nearly vertical anteriorly; pronotal side smooth but oblique groove anteriorly and posterior groove coarsely crenulate (Fig. 419); epicnemial area with few crenulae dorsally; precoxal sulcus distinctly impressed, but posterior 0.4 absent, and coarsely crenulate (Fig. 419); pleural sulcus distinctly crenulate; mesosternal sulcus and postpectal carina not visible because of glue; metapleuron coarsely reticulate ventrally and dorsally largely smooth (except some punctures); notauli impressed and with few crenulae anteriorly, and largely absent on disc; mesoscutum flattened, with large elliptical medio-posterior depression, setose and punctulate; scutellar sulcus wide and with 3 coarse crenulae (Fig. 420); scutellum rather flat and sparsely punctulate; metanotum with weak median carina; propodeum posteriorly largely smooth, with coarse curved transverse carina in front of middle and anteriorly rugose and with rather short median carina (Fig. 420).

Wings. Fore wing (Fig. 418): pterostigma triangular; 1-R1 ending close to wing apex and 1.3 times as long as pterostigma; r:3-SR:SR1 = 5:16:50; 2-SR:3-SR:r-m = 16:16:5; r slender; 1-M and SR1 slightly curved; m-cu just postfurcal; cu-a slightly postfurcal and 1-CU1 hardly widened; first subdiscal cell closed, CU1b medium-sized and shorter than 3-CU1; M+CU1 sclerotized. Hind wing: M+CU:1-M:1r-m = 25:18:12; cu-a straight; m-cu absent.

Legs. Length of femur, tibia and basitarsus of hind leg 3.8, 7.0 and 3.7 times as long as wide, respectively (Fig. 427); hind femur with long setae and tibia densely rather short setose; third and fourth segments of fore tarsus distinctly longer than wide and about as long as wide, respectively.

Metasoma . Length of first tergite 0.8 times its apical width, its surface smooth in front of united dorsal carinae and coarsely punctate-reticulate behind carinae, convex and no median carina posteriorly (Fig. 421); second suture coarsely crenulate, nearly straight, slightly widened medially and distinctly impressed; second tergite with row of punctures between longitudinal striae; median length of second tergite 2.1 times median length of third tergite; third tergite mainly with rows of punctures, but medially and posteriorly smooth; following tergites smooth and largely retracted below carapace; length of setose part of ovipositor sheath 0.22 times fore wing, 0.6 times first-third tergites combined and 0.8 times longer than hind tibia; hypopygium far retracted, truncate apically and about 0.2 times as long as metasomal carapace.

Colour. Dark brown, including pterostigma, veins and antenna (but scapus yellow); head and mandible yellow, but head medio-dorsally and posteriorly infuscate; ovipositor sheath blackish; wing membrane subhyaline.
