Figs 8, 9 , 12–14

Etymology: From Latin largus (bountiful).

Description:

Female.

Body length 2.8 mm.

Head strongly and rather linearly narrowed behind eyes in dorsal view; temple almost 0.6 times as long as eye width. Flagellum with 14 segments; all flagellomeres distinctly elongate ( Fig. 9 ). Upper tooth of mandible longer than lower tooth. Malar space slightly longer than basal width of mandible. Face and frons granulate, sometimes also finely punctate. Vertex very finely granulate, matt. Temple usually smooth and shining, sometimes finely granulate.

Mesonotum granulate and finely punctate. Notaulus absent or weak. Mesopleuron granulate, sometimes also finely punctate. Sternaulus in anterior part of mesopleuron oblique, moderately impressed and transversely wrinkled. Propodeum entirely granulate, impunctate; basal keel about 0.4 times as long as apical area; spiracle separated from pleural carina by about 2.0 diameters of spiracle; apical area rounded ( Fig. 13 ) or slightly pointed (producing angle about 85°) anteriorly, its longitudinal carinae weak anteriorly, usually reaching transverse carina.

Fore wing length 2.3 mm. First section of radial vein much longer than width of pterostigma. Metacarp not reaching apex of fore wing. Second recurrent vein postfurcal ( Fig. 12 ).

First tergite length 0.68 mm, posterior width 0.18 mm; tergite slender, almost entirely smooth, with petiole slightly striate laterally, without glymma. Second tergite length 0.23 mm. Thyridia about 1.5× as long as wide. Ovipositor short, robust, with more or less distinct roundish tooth before dorsal subapical depression ( Fig. 14 ); sheath 0.67 mm, as long as first tergite or slightly shorter.

Body primarily black. Palpi, mandibles (except teeth), lower half of clypeus (upper half reddish below to black above), scape and pedicel of antenna (entirely or only ventrally), tegula and legs brownish yellow (rarely hind coxa brown basally). Flagellum usually brownish yellow basally, evenly darkening towards apex, or rarely entirely darkened. Pterostigma brown. Metasoma behind first segment usually brownish yellow ventrally to brown dorsally, or sometimes entirely brown or dark brown.

Male.

Similar to female. Flagellum of antenna with 14 segments. Malar space about as long as basal width of mandible. Sternaulus sometimes very weak.
