Female.— Body length 4.55 mm.

Body color ( Fig. 16 View FIGURE 16 A): mainly black. Flagellomeres dark brown. Basal part of scape as well as pedicel dark brown but apex with a light brown hoop. Annellus light brown. Labrum and mandible yellow-brown. Mandibular teeth red-black. Labial and maxillary palps light yellow. All legs yellow-brown except the apex hind tibia and tarsus dark brown and hind femur with a central black stripe. Fore wing ( Fig. 16 View FIGURE 16 F): tegula with a central, round dark brown spot; C+Sc+R, M+CU and 1–1A veins of same color throughout; stigma dark brown. Membrane of both fore and hind wings light brown and with brown microtrichiae. Body slender with long pubescence.

Head ( Figs. 16 View FIGURE 16 A–B). — Subtriangular. Antenna with 14 flagellomeres; first three flagellomeres longer than wide (0.18:0.08; 0.25:0.08; 0.22: 0.08 mm); last five, except the last one, longer than wide (0.10:0.09; 0.10:0.09; 0.12:0.09; 0.14:0.09; 0.15: 0.09 mm); apical flagellomere longer than penultimate segment (0.20: 0.10 mm); scape longer than first flagellomere (0.23: 0.18 mm) and wider than pedicel and first flagellomere (0.13:0.08: 0.08 mm.); pedicel more than half as long as scape (0.15: 0.23 mm). Torulus ( Fig. 16 View FIGURE 16 B) located above midline of the eye. Frons ( Fig. 16 View FIGURE 16 B) with a longitudinal median lamella, in lateral view arched, like a hump; the lamella arising from ventral margin of toruli, crossing the frons and forking Y-shaped before reaching the median ocellus; a deep and circular depression is formed below median ocellus and between the forks, depression with large punctures; only middle basal part of lamella with deep and large punctures and the other parts smooth and shiny; laterally frons with small and dense punctures near toruli, but scarce next to vertex, the same happening with the long and dense pubescence near toruli, that begin to be scarce as they approach the vertex. Scrobes shallow, smooth, shiny, and very wide, not surrounded by a carina; scrobes reach the vertex. Lower face with a round, central and small depression at half length of eye; lower face nearly flat, with small and dense punctures distributed homogeneously; interspaces shiny and smooth. Fronto-clypeal suture strongly impressed, round and with deep and dense punctures. Anterior tentorial pit not embedded within a strong depression. Clypeus convex not on same plane as lower face, with small punctures of different sizes; interspaces smooth and shiny; apical part reflexed, narrow, shiny, smooth; with a defined edge and without carina, medioapical margin of clypeus weakly concave. Labrum with large punctures distributed homogeneously; interspaces wide, smooth and shiny. Mandible long and slender, basal part with carinate-rugose; mandible set with two smooth, shiny teeth; superior teeth longer than inferior; apex of teeth sharp. Maxillary palps longer than labial. Ocelli ( Fig. 16 View FIGURE 16 B) oval; lateral ocelli close to each other, separated by less than the width of lateral ocellus (0.05: 0.07 mm) and not surrounded by carina. Stemmaticum shiny, smooth, but with some sparse punctures; pubescence scarce and short; stemmaticum higher than vertex forming a projection like a plateau, highest point flat. Eyes without preorbital carina. Vertex without carina, shiny and smooth but some small and very sparse punctures. Occiput concave, smooth and shiny with some long pubescence. Occipital carina absent. Temple and gena with small and dense punctures distributed homogeneously; interspaces wide, smooth and shiny.

Mesosoma ( Figs. 16 View FIGURE 16 A, C–E). — Projection of propleuron blunt. Pronotum ( Fig. 16 View FIGURE 16 C) anteriorly with a strong groove throughout the edge, containing punctures; curvature of pronotum with large punctation, although with an expanded smooth and shiny area; dorsally and ventrally with deep punctures of different sizes only throughout the edge. Pronotal lobe at different level than pronotum, sloped toward tegula, point of inflection carinated, apex rounded ( Fig. 16 View FIGURE 16 C). Mesoscutum in dorsal view uneven ( Fig. 16 View FIGURE 16 D), punctures small, sparser in lateral than median mesonotal lobe; interspaces very wide, smooth and shiny; lateral mesonotal lobes flat with a weak slope toward anterior part; throughout the edge with some punctures of different size and other parts without punctation; median mesonotal lobe with one longitudinal median and continuous carina; carina is more than half as long as mesonotal lobe; laterally with a defined and high edge; posteriorly with large punctures nearly of same size; area of convergence of notauli with three large punctures, one of them below longitudinal median carina. Notauli ( Fig. 16 View FIGURE 16 D) strongly impressed, with large punctures along entire length; notauli distant from edge of transscutal articulation and without additional row of punctures along entire length. Scutellum ( Fig. 16 View FIGURE 16 C) slightly more sloped that mesoscutum; central part of scutellum smooth and shiny, but edges with large, heterogeneous punctures; posteriorly not sloped, on same vertical plane as posterior scutellar depression; scutellar sulcus with four deep and homogeneous foveae; posterior scutellar depression smooth, but with some small punctures that do not fill wholly the smooth area. Middle part of metanotum with a weak projection below posterior scutellar depression ( Fig. 16 View FIGURE 16 C). Propodeum ( Fig. 16 View FIGURE 16 D) antero-posteriorly short, symmetrical; MLC high, but without anterior projection or spine; ATC high with a strong invagination and later reaching the same length of MLC; AMA elongates with apex acuminate, triangle-shaped; LLC inclined; posterior wall of propodeum slight convex, with areolae of different sizes. Metapleuron with large, irregular areolae. Mesopleuron ( Fig. 16 View FIGURE 16 C) lacks epicnemial carina and sternaulus; mesopleuron convex with shiny, smooth central area; dorsally, below tegula, with three conspicuous depressions; ventrally with a deep dent which bears large, heterogeneous punctures throughout the edge; anteriorly with elongate, narrow, flat area that bears small, dense punctures throughout the edge; posteriorly scrobiculate. Mesosternum ( Fig. 16 View FIGURE 16 E) slightly convex, with small and sparse punctures, with a complete central row of foveae with similar size and shape and surrounded by carinae; lateral part without carinae; mesosternum near fore coxa with a high lamella with only one sharp and central edge, but near mid coxa carina is semi-arched.

Wings ( Figs. 16 View FIGURE 16 A, F). — Fore wing: vein M+CU markedly curved (sinuate); vein 3RSb tubular, distant from stigma (0.62 mm); subbasal cell as long as basal (1.47: 1.47 mm); stigma elongate. Fore wing: length 3.15 mm, width 1.20 mm; hind wing: length 2.75 mm, width 0.70 mm.

Metasoma ( Fig. 16 View FIGURE 16 A). — Carapace in lateral view elongate, strongly fusiform ( Fig. 16 View FIGURE 16 A); anteriorly with strong substrigulates that cross more than 2/3 of length of the carapace; area between the carinae lacunose. Apex of carapace without tubercles, shiny and with scarce and small punctures. Ovipositor ( Fig. 16 View FIGURE 16 A) length 2.9 mm. Carapace length 2.1 mm.

Male.— Unknown.

Biology.— Unknown.

Comments.— This species differs from U. remotonotaularis because central row of fovea on mesosternum is surrounded by carinae. This species is black and shiny. Body length from 4.25 to 4.75 mm.
