Female.— Body length 3.3 mm.

Body color ( Fig. 23 View FIGURE 23 A): mainly black. Flagellomeres, scape dark brown. Pedicel dark brown, but with a slender light brown stripe in the apex. Annellus, labrum, mandible, labial and maxillary palps light brown. Mandibular teeth red-brown. Projection of metapleuron with dark brown apex. Fore and mid legs yellow except coxa and the fifth tarsomeres light brown. Hind legs dark brown except trochanter, trochantellus and basal third of tibia light brown. Fore wing ( Fig. 23 View FIGURE 23 G): tegula black with central brown spot; stigma dark brown. Membrane of both fore and hind wings light brown and with brown microtrichiae.

Head ( Fig. 23 View FIGURE 23 A–B).—Subquadrate. Antenna with 12 flagellomeres; first three flagellomeres longer than wide (0.20:0.07; 0.20:0.07; 0.20: 0.07 mm); last five, except the last one, longer than wide (0.11:0.07; 0.12:0.07; 0.13:0.07; 0.14:0.07; 0.15: 0.07 mm); apical flagellomere longer than penultimate (0.20: 0.11 mm); scape shorter than first flagellomere (0.18: 0.20 mm) and wider than pedicel and first flagellomere (0.09:0.06: 0.07 mm); pedicel less than half as long than scape (0.08: 0.17 mm). Torulus ( Fig. 23 View FIGURE 23 B) located above midline of the eye. Frons with a deep longitudinal median groove surrounded by high lateral carinae which reach the lateral region of ventral margin of lateral ocelli; groove narrower ventrally than dorsally; inside groove with irregular rugose areolae and some conspicuous semicircular carinae; laterally frons with deep, small punctures and wavy interspaces. Scrobes shallow, wide, not surrounded by carina, with small, sparse, homogeneous punctures; scrobes reaching the dorsal part of median ocellus. Lower face ( Fig. 23 View FIGURE 23 B) strongly convex, without protuberance, and with dense punctures distributed heterogeneously. Fronto-clypeal suture smooth, rounded, strongly impressed. Anterior tentorial pit not embedded within a strong depression. Clypeus convex with some scarce and small punctures; apical part reflexed, shiny and with a strong and wavy carina that runs from one end to the other. Labrum with small and sparse punctures, interspaces smooth. Mandible long, slender, basally with transverse strigae; mandible set with two short, stout teeth; inferior teeth as long as superior; teeth with sharp apex. Maxillary palps much longer than labial ( Fig. 23 View FIGURE 23 B). Ocelli oval; lateral ocelli distant from each other, separated by more than the width of lateral ocellus (0.007: 0.005 mm); surrounded by a dorsal carina. Stemmaticum with a deep longitudinal median groove, laterally elevated; groove with conspicuous semicircular carinae; stemmaticum strongly, higher than vertex, elevated into a conspicuous projection; highest point concave. Eyes ( Fig. 23 View FIGURE 23 B) without preorbital carina. Vertex with deep punctates, but medially larger than laterally, interspaces wavy, shiny, smooth; vertex without longitudinal median carina. Occiput concave, smooth, shiny. Occipital carina present completely. Temple and gena with small, sparse punctures distributed homogeneously.

Mesosoma ( Figs. 23 View FIGURE 23 A, C–E). — Projection of propleuron blunt. Pronotum anteriorly and curvature of pronotum with heterogeneous areolae which are larger than posteriorly. Pronotal lobe ( Fig. 23 View FIGURE 23 E) sloped toward tegula with rounded apex; point of inflection carinated. Mesoscutum ( Fig. 23 View FIGURE 23 C) uneven; lateral mesonotal lobes with small, homogeneously distributed punctures; anteriorly sloped; posteriorly convex; edge with deep areolae of different sizes throughout; median mesonotal lobe convex and distinctively higher than lateral lobes, with longitudinal median carina, which is less than half the length of median mesonotal lobe, carina with highest point at anterior end, posterior end with an elongate fovea; area of convergence of notauli with large, irregular areolae forming an inverted triangle. Notauli strongly impressed with large foveae, round anteriorly, but posteriorly elongate; notauli near edge of transscutal articulation, without additional row of foveae along the entire length. Scutellum triangular, medially convex, projected, higher than mesoscutum ( Fig. 23 View FIGURE 23 E), apex concave, deep and with a carinated depression that bears punctures; scutellum with sparse, small punctures, but laterally lacunose; posteriorly on different vertical plane than posterior scutellar depression, it stands out in profile ( Fig. 23 View FIGURE 23 E); scutellar sulcus with four deep, subequal foveae; posterior scutellar depression smooth with two rounded, large foveae that fill most of the smooth area. Middle part of metanotum, below posterior scutellar depression, with a strong projection conspicuous in lateral view ( Fig. 23 View FIGURE 23 E). Propodeum antero-posteriorly short, symmetrical; crossed by high MLC conspicuous in lateral view ( Fig. 23 View FIGURE 23 E); ATC high, strong, oblique throughout; AMA absent; posterior wall of propodeum flat with small areolates. Metapleuron with large areolates of different sizes. Mesopleuron with epicnemial carina, but lacks sternaulus; mesopleuron convex with shiny, smooth central area; dorsally with foveae, one of them deep, large below the tegula and the other small below the large one; ventrally delimited by the lateral carina of mesosternum, but also with a dent that bears small punctures throughout; anteriorly with sparse, small punctures; posteriorly scrobiculate. Mesosternum ( Fig. 23 View FIGURE 23 D) flat, with small, sparse punctures, with a complete central row of foveae not surrounded by carinae; each lateral part delimited by a strong carina that turns inward in posterior third of mesosternum; mesosternum near fore coxa with a high transverse lamella with two elevations below each coxa; mesosternum near mid coxa with large, deep foveae that form a diamond-like shape.

Wings ( Figs. 23 View FIGURE 23 A, G). — Fore wing ( Fig. 23 View FIGURE 23 G): veins M+CU and markedly curved (sinuate); vein 3RSb tubular, distant from stigma (0.45 mm); subbasal cell longer than basal (1.08: 1.02 mm); stigma short, relatively round. Fore wing: length 2.25 mm, width 0.72 mm; hind wing: length 2.00 mm, width 0.48 mm.

Metasoma ( Figs. 23 View FIGURE 23 A, F). — Carapace in lateral view elongate, fusiform ( Fig. 23 View FIGURE 23 A); anteriorly with strong substrigulae that cross more than half the length of the carapace; area between carinae lacunose. Ventrally apex of carapace with a deep, longitudinal groove with low lateral ridges that form two insconspicuous tubercles ( Fig. 23 View FIGURE 23 F); apex of carapace convex. Ovipositor ( Fig. 23 View FIGURE 23 A) length 0.78mm. Carapace length 1.55 mm.
