Figs. 5 View FIGURE 5 A–G

Female.— Body length 4.1 mm.

Body color ( Fig. 5 View FIGURE 5 A): mainly black. Flagellomeres, scape, pedicel and labrum dark brown. Annellus light brown. Mandible red-brown. Labial and maxillary palps yellow-brown. All legs yellow-orange except two apical thirds of hind tibia and hind tarsus dark brown. Fore wing ( Fig. 5 View FIGURE 5 G): M+CU and 1–1A veins lighter basally than apically; tegula black with brown central spot; stigma dark brown. Membrane of both fore and hind wings light brown; microtrichiae of hind wings hyaline, but fore wings brown.

Head ( Figs. 5 View FIGURE 5 A, D). — Subquadrate. Antenna ( Fig. 5 View FIGURE 5 A) with 14 flagellomeres; first three flagellomeres longer than wide (0.20:0.07; 0.25:0.07; 0.21: 0.07 mm); last five, except the last one, as long as wide (0.09:0.10; 0.09:0.10; 0.10:0.10; 0.10:0.10; 0.11: 0.10 mm); apical flagellomere longer than penultimate segment (0.20: 0.10 mm); scape longer than first flagellomere (0.28: 0.20 mm), and wider than pedicel and first flagellomere (0.12:0.08: 0.07 mm); pedicel less than half as long as scape (0.12: 0.28 mm). Torulus ( Fig. 5 View FIGURE 5 A) located at midline of the eye. Frons with three carinae: two lateral, one longitudinal median carina; lateral carinae ventrally narrower than anteriorly, there tilted and running toward both sides of the median ocellus forming obcordate (heart) shape; inside this shape a longitudinal median carina reaching ventral margin of median ocellus, longitudinal median carina intercepted with several, short transverse carinae. Scrobes deep, narrow, smooth, shiny, not surrounded by carina and reaching the vertex ( Fig. 5 View FIGURE 5 D). Lower face strongly convex with small, dense punctates. Fronto-clypeal suture not conspicuous although some fold present there. Anterior tentorial pits not evident externally. Clypeus flat, on same plane as lower face, punctates small, irregular; interspaces shiny although apically some areas with short longitudinal folds; apical part reflexed, narrow, shiny, with carinated edge, longitudinal strigae throughout the surface. Labrum scabrous. Mandible short, slender, base with transverse strigae; mandible set with two teeth, superior teeth much longer than inferior; teeth long, slender with sharp apexes. Maxillary palps longer than labial. Ocelli oval, not surrounded by carina, lateral ocelli distant from each other, separated by the width of lateral ocellus (0.07: 0.08 mm). Stemmaticum flat, slightly more elevated than vertex-deep scrobes ( Fig. 5 View FIGURE 5 D); elevation flat; stemmaticum mostly smooth, but with scarce, small punctures. Eyes without preorbital carina. Vertex with sparse, small punctures ( Fig. 5 View FIGURE 5 D), without longitudinal median carina. Occiput concave, smooth and shiny. Occipital carina absent throughout. Temple and gena with small, sparse punctures.

Mesosoma ( Figs. 5 View FIGURE 5 A–B, E–F). — Projection of propleuron blunt. Pronotum anteriorly with small punctures; dorsally with a large area with small punctures and some small depressions; posteriorly scrobiculate; curvature of pronotum with large punctures, the rest of pronotum smooth. Pronotal lobe sloped toward tegula; point of inflexion carinated; apex truncate. Mesoscutum uneven ( Fig. 5 View FIGURE 5 B), with small, sparse punctures; posteriorly both lateral and medial mesonotal lobes on same plane; anteriorly lateral mesonotal lobes sloped, but posteriorly convex, edge of lateral mesonotal lobes with deep foveae, but not throughout; anteriorly median mesonotal lobe with discontinuous antero-transverse carina that runs from one end to the other with three elevations: one medial and two lateral ones; area of convergence of notauli with a single median and elongate fovea. Notauli strongly impressed with large, elongate foveae throughout, without additional row of foveae throughout; notauli near edge of transscutal articulation ( Fig. 5 View FIGURE 5 B). Scutellum flat, triangular, on same plane as mesoscutum; anteriorly smooth and shiny; posteriorly with two longitudinal and lateral depressions filled with lacunose sculpture, interspaces wide and smooth; posteriorly sloped, on same vertical plane as posterior scutellar depression; scutellar sulcus with four deep subequal foveae; posterior scutellar depression with two small areolae that do not completely fill the smooth area. Middle part of metanotum, below posterior scutellar depression, with a strong projection conspicuous in lateral view. Propodeum antero-posteriorly short, asymmetrical ( Fig. 5 View FIGURE 5 B); MLC high and strong, but without anterior projection (spine); ATC high with strong invagination and later reaching the same length as MLC; AMA irregularshaped ( Fig. 5 View FIGURE 5 B); LLC wavy; posterior wall of propodeum flat, with areolae of different sizes. Metapleuron with large, irregular areolae. Mesopleuron with epicnemial carina ( Fig. 5 View FIGURE 5 E), without sternaulus; mesopleuron convex with shiny, smooth central area; dorsally with one deep, transverse depression below tegula and another depression forming a semicircular area; ventrally a dent with a row of large, deep punctures forming a wavy, L-shaped carina; anteriorly with elongate, narrow, flat area that bears small, dense punctures throughout the edge; posteriorly scrobiculate although with some large foveae ( Fig. 5 View FIGURE 5 E). Mesosternum convex with a complete central row of foveae not surrounded by carinae ( Fig. 5 View FIGURE 5 F); lateral parts with small and sparse punctures, not delimited by carinae, although with a conspicuous edge; mesosternum near fore coxa forming sharp edge only in the middle part, mesosternum near mid coxa with elongated, large areolae.

Wings ( Figs. 5 View FIGURE 5 A, G). — Fore wing ( Fig. 5 View FIGURE 5 G): vein M+CU markedly curved (sinuate); vein 3RSb tubular, distant from stigma (0.63 mm); subbasal cell longer than basal (1.38: 1.27 mm); stigma short and relatively rounded. Fore wing: length 3.25 mm, width 1.15 mm; hind wing: length 2.50 mm, width 0.70 mm.

Metasoma ( Figs. 5 View FIGURE 5 A, C). — Carapace in lateral view elongate, more fusiform ( Fig. 5 View FIGURE 5 A); anteriorly with strong substrigulae that cross more than half the length of the carapace; area between carina with some punctates, but mostly smooth ( Fig. 5 View FIGURE 5 C). Apex of carapace with a medial protuberance with rounded apex ( Fig. 5 View FIGURE 5 A); region above protuberance sloped. Apically carapace smooth and shiny. Ovipositor ( Fig. 5 View FIGURE 5 A) length 1.85 mm. Carapace length 2.4 mm.
