Description:

Female.

Body length 3.1 mm.

Head strongly and moderately roundly narrowed behind eyes in dorsal view; temple 0.57 times as long as eye width.Antenna with 14-segmented flagellum; all flagellomeres distinctly elongate ( Fig. 22 ). Upper tooth of mandible longer than lower tooth. Malar space subequal to or slightly longer than basal width of mandible (distinctly shorter in female from Dikbome). Face and frons granulate. Vertex finely granulate, matt. Temple finely granulate and matt to smooth and shining.

Mesonotum granulate and indistinctly punctate. Notaulus substituted by a short, strong carina. Mesopleuron granulate, sometimes almost smooth and finely punctate centrally. Sternaulus in anterior part of mesopleuron oblique, slightly impressed, usually with more or less developed transverse wrinkles. Propodeum entirely granulate, impunctate; basal keel very short, 0.24–0.29 times as long as apical area; spiracle separated from pleural carina by about 2.0 diameters of spiracle; apical area strongly acute anteriorly ( Fig. 23 ), its longitudinal carinae weaker anteriorly, reaching or not reaching transverse carina.

Fore wing length 2.33 mm. First section of radial vein much longer than width of pterostigma. Metacarp not reaching apex of fore wing. Second recurrent vein postfurcal.

First tergite length 0.68 mm, posterior width 0.19 mm; tergite slender, smooth, usually with small glymma. Second tergite length 0.28 mm. Thyridia 1.5–2.0 times as long as wide, sometimes very shallow. Ovipositor short ( Fig. 24 ); sheath 1.28 mm, almost 1.9 times as long as first tergite.

Body primarily black. Palpi, mandibles (except teeth), lower 2/3 of clypeus (upper third reddish blackish), scape and pedicel of antenna, tegula and legs (apical tarsomeres more or less infuscate) brownish yellow. Flagellum yellowish basally, evenly darkening towards apex. Pterostigma brown, with pallid marks basally and apically. Metasoma with segment 1 brown to black with brownish hue, following segments brownish yellow ventrally to brown or dark brown dorsally.

Male.

Similar to female. Flagellum of antenna with 14 segments. Malar space distinctly shorter than basal width of mandible.
