Fore wing ( Fig. 15 View FIGURE 15 G): tegula black with brown central spot; basal parts of C+Sc+R, M+CU and 1 – 1 A veins lighter than apical part; stigma dark brown; membrane of both fore and hind wings light brown and with brown microtrichiae. Body slender with light, long, dense pubescence.

Antenna with 14 flagellomeres; first three flagellomeres longer than wide (0.25: 0.12; 0.32: 0.12; 0.27: 0.12 mm); last five, except the last one, longer than wide (0.15: 0.09; 0.16: 0.09; 0.17: 0.09; 0.18: 0.09; 0.20: 0.09 mm); apical flagellomere longer than penultimate (0.30: 0.17 mm); scape longer than first flagellomere (0.4: 0.25 mm), and wider than pedicel and first flagellomere (0.15: 0.10: 0.12 mm); pedicel less than half as long as scape (0.40: 0.15 mm). Torulus located at midline of the eye. Frons ( Fig. 15 View FIGURE 15 B) with a high longitudinal median lamella, in lateral view arched and hump-like; lamella crosses the frons and forks into Y before reaching the median ocellus; each branch of Y runs to lateral parts of median ocellus, a deep, circular depression is formed below median ocellus and between the forks; lamella shiny, smooth although with some sparse punctures; laterally frons with small, dense punctures near toruli, but scarce near vertex. Scrobes ( Fig. 15 View FIGURE 15 B) deep, smooth, shiny, not surrounded by a carina and very wide that extends great part of frons; scrobes reaching vertex. Lower face slightly flat, with small, dense punctures distributed homogeneously, interspaces shiny and smooth. Fronto-clypeal suture strongly impressed, round and with small, dense punctures. Anterior tentorial pit not embedded within a strong depression. Clypeus convex, not on same plane as lower face, with small, dense and homogeneously distributed punctures; interspaces shiny and smooth; apical part reflexed, narrow, smooth, and shiny with a defined edge, but without carina. Labrum with dense and small punctures. Mandible long and slender, basally carinate-rugose; mandible set with two long, sharp teeth; superior teeth longer and wider than inferior. Maxillary palps longer than labial palps. Ocelli oval not surrounded by carina; lateral ocelli distant from each other, separated by the width of lateral ocellus (0.009 mm). Stemmaticum ( Fig. 15 View FIGURE 15 B) with scarce, small, sparse punctures; interspaces wide, shiny; stemmaticum more elevated than vertex, forming a projection like a plateau, highest point flat. Eyes without preorbital carina ( Fig. 15 View FIGURE 15 B). Vertex with small, very sparse punctures, without longitudinal median carina. Occiput concave, smooth, shiny and with pubescence only ventrally. Occipital carina absent. Temple and gena with small, homogeneous and dense punctures; interspaces narrow, smooth and shiny.

Mesosoma ( Figs. 15 View FIGURE 15 A, D –F). — Projection of propleuron blunt. Pronotum with sparse, large punctures; interspaces wide, shiny and smooth; curvature of pronotum smooth and shiny; dorsally scrobiculate along edge. Pronotal lobe ( Fig. 15 View FIGURE 15 E) on same plane as pronotum and with rounded apex. Mesoscutum ( Fig. 15 View FIGURE 15 D) uneven with small, homogeneous punctation, but sparser in lateral mesonotal lobes than in median; lateral mesonotal lobes slightly sloped anteriorly with punctures of different sizes, some parts smooth throughout lateral edge; median mesonotal lobe flat with one continuous longitudinal median carina more than half as long as mesonotal lobe; median mesonotal lobe edges well defined, so each side with a continuous longitudinal lateral carina ( Fig. 15 View FIGURE 15 D); area of convergence of notauli with four large foveolae, one of these at end of longitudinal median carina. Notauli with large, heterogeneous and deep areolation throughout; notauli far away from edge of transscutal articulation and without additional row of punctates ( Fig. 15 View FIGURE 15 D). Scutellum, flat, triangular, on same plane as mesoscutum ( Fig. 15 View FIGURE 15 E); region near scutellar sulcus with small, sparse punctures; posteriorly strongly sloped and reaches the posterior scutellar depression; with central carina crossing the scutellum from scutellar sulcus to posterior scutellar depression; apex of scutellum with two deep and wide depressions at each side which are separated by a central carina; scutellar sulcus with four deep and homogeneous foveae; posterior scutellar depression with two large and triangular foveae that fill the whole smooth area, foveae separated by the central carina that comes from scutellum. Middle part of metanotum with a high carina below posterior scutellar depression, but without projection. Propodeum antero-posteriorly short ( Fig. 15 View FIGURE 15 D), symmetrical; MLC short, but does not forming a conspicuous anterior projection (spine); ATC high, wavy, on same plane as MLC; AMA triangle-shaped ( Fig. 15 View FIGURE 15 D); LLC inclined; posterior wall of propodeum convex, with large areolate-rugose. Metapleuron with large, irregular areolate-rugose sculpture. Mesopleuron ( Fig. 15 View FIGURE 15 E) without epicnemial carina and sternaulus; mesopleuron convex; shiny central area with scarce, small punctures; dorsally, below tegula, mesopleuron with depressions of different sizes and depths, each depression with large areolae; ventrally with a wide, deep dent, crossing antero-posteriorly, depression in its great part smooth, but with some foveolae of different sizes; anteriorly with small, dense, homogeneous punctures; posteriorly scrobiculate throughout. Mesosternum ( Fig. 15 View FIGURE 15 F) convex, with a complete central row of foveae with similar size and shape not surrounded by carinae; lateral parts of mesosternum not delimited by carinae and with small and sparse punctures; mesosternum near fore coxa with a high lamella with two higher ridges, but near mid coxa without carina and with punctures of different sizes.

Wings ( Figs. 15 View FIGURE 15 A,G). — Fore wing: vein M+CU markedly curved (sinuate); vein 3 RSb tubular, distant from stigma (0.83 mm); subbasal cell as long as basal (1.83: 1.85 mm); stigma elongate. Fore wing: length 4.25 mm, width 1.28 mm; hind wing: length 3.30 mm, width 0.77 mm.

Metasoma ( Figs. 15 View FIGURE 15 A, C). — Carapace in lateral view elongate ( Fig. 15 View FIGURE 15 A), more fusiform; anteriorly with strong substrigulae ( Fig. 15 View FIGURE 15 C) that cross more than half the length of the carapace; area between the carinae lacunose. Apex of carapace without tubercles (teeth); ventrally with a medial groove, each side of the groove with large, sparse punctures; interspaces smooth and shiny. Ovipositor ( Fig. 15 View FIGURE 15 A) length 5.20 mm. Carapace length 2.70 mm.



Comments.—The number and shape of foveolae in the apical part of median mesonotal lobe are variable. This species has homogeneous sculpture, body with long and dense pubescence. This species has body shiny, smooth, slim and darker. Body length from 5.20 to 6.05 mm.

Etymology.— From notauli and remotus (Latin, adjective) = distant, far off, remote. The name refers to the location of the notauli, which are distant from the transscutal articulation.
