Figs. 11 A–G Female.— Body length 2.75 mm . Body color ( Fig. 11 A): mainly black. Scape apically with a light brown ring, basally dark brown. Labrum and mandible light brown. Labial and maxillary palps yellow-brown. All legs yellow-brown except last apical third of hind femur, two apical thirds of hind tibia and hind tarsus brown. Fore wing ( Fig. 11 G): basally C+Sc+R veins darker than apically; tegula yellow-brown, stigma light brown. Membrane and microtrichiae of fore wings light brown, but hind wings hyaline. Pubescence over the body scarce. Head ( Figs. 11 A–B). Subtriangular ( Fig. 11 B). Scape longer than wide (0.18:0.08). Torulus located at midline of the eye. Frons sloped laterally and crossed by a longitudinal median carina the central part of which is higher than both the posterior and anterior ends, carina does not reach ventral part of median ocellus; frons with small punctures around carina that disappear when approaching to median ocellus; below median ocellus with a small, deep depression with sculpture. Scrobes shallow, wide, not surrounded by carina; ventrally smooth, shiny; laterally with small and sparse punctures; scrobes reach the dorsal part of lateral ocelli. Lower face ( Fig. 11 B) strongly convex with a small drop-like fovea aligned with medial carina of frons, lower face with small and dense punctures; interspaces shiny and smooth. Fronto-clypeal suture strongly impressed, round, with sculpture. Anterior tentorial pit not embedded within a strong depression. Clypeus convex, with small and dense punctures; interspaces shiny and smooth; apical part reflexed, wide, smooth, shiny, with a defined edge, but not surrounded by carina. Labrum with small and sparse punctures; interspaces smooth. Mandible long, slender, basally with transverse strigae; mandible set with two long, slender teeth; inferior teeth as long as superior; all teeth sharp. Maxillary palps much longer than labial ( Fig. 11 B). Ocelli round; lateral ocelli without carina, separated by more than diameter of lateral ocellus (0.08: 0.05 mm ). Stemmaticum elevated into a weak projection ( Fig. 11 B), slightly higher than vertex, with a shallow, longitudinal median depression, with sparse and small punctures; interspaces wide and shiny; highest point of stemmaticum convex. Eyes without preorbital carina. Vertex without carina and with small and sparse punctures. Occiput concave, smooth and shiny. Occipital carina complete ( Fig. 11 C). Temple and gena with small, sparse and homogeneous punctures; interspaces smooth and shiny. FIGURE 11 . Urosigalphus macarenaensis n. sp. (A) habitus; (B) head, frontal view; (C) head and mesosoma, dorsal view; (D) propodeum and carapace, dorsal view; (E) mesosoma, lateral view; (F) mesosternum; and (G) fore wing. Mesosoma ( Figs. 11 A, C, E–F). Projection of propleuron blunt. Pronotum ( Fig. 11 E) dorsally and posteriorly with heterogeneous areolae; curvature of pronotum with large areolae; middle part smooth and shiny; anteriorly distinctive longitudinal groove with small and deep punctures; ventrally with large, deep areolae. Pronotal lobe sloped toward tegula; point of inflection carinated; apex truncate. Mesoscutum ( Figs. 11 C,E) uneven; lateral mesonotal lobes with small and sparse punctures, but edge with deep and irregular areolae; anteriorly with wavy transverse carina; lateral lobes anteriorly slightly sloped, but posteriorly convex; median mesonotal lobe higher than lateral lobes, with a continuous longitudinal median carina which is less than half as long as median mesonotal lobe; lateral edges defined by a strong edge, with small and sparse punctures; area of convergence of notauli without defined shape and with deep, large foveae. Notauli strongly impressed with large and elongate foveae throughout, without additional row of foveae and near edge of transscutal articulation. Scutellum convex, medially higher than mesoscutum ( Fig. 11 E), with heterogeneous, deep and carinated areolae; middle part convex; posteriorly not sloped, on same vertical plane as posterior scutellar depression; scutellar sulcus with four deep and uneven foveae; posterior scutellar depression with two square foveae that fill the whole smooth area. Middle part of metanotum, below posterior scutellar depression, with a strong anterior projection conspicuous in lateral view ( Fig. 11 E). Propodeum antero-posteriorly short, symmetrical; MLC short; ATC diagonal upward and later reaches the height of MLC; AMA irregular without defined shape; LLC slightly inclined; posterior wall of propodeum flat, with areolae of different sizes. Metapleuron with areolae of different sizes. Mesopleuron ( Fig. 11 E) with epicnemial carina, but lacks of sternaulus; mesopleuron convex; dorsally with three rows of punctures, one of them below tegula; ventrally with a dent with foveae of different sizes; anteriorly with an area of small, dense punctures throughout, with deep, small areolae forming a semicircle; posteriorly scrobiculate. Mesosternum ( Fig. 11 F) convex with a complete central row of foveae, not surrounded by carina; laterally with small and sparse punctures and with strong and almost straight carina; mesosternum near fore coxa with a sharp transverse edge of same height along the edge; mesosternum near mid coxa with wavy, transverse carina and a semicircular area above mid coxa, middle part of semicircular carina intercepted by lateral carina. Wings ( Figs. 11 A, G). Fore wing ( Fig. 11 G): vein M+CU markedly curved (sinuate); vein 3RSb tubular, distant from stigma ( 0.38 mm ). Subbasal cell longer than basal (0.92: 0.87 mm ); stigma short and round. Fore wing: length 2.00 mm, width 0.85 mm ; hind wing: length 1.75 mm , width 0.47 mm . Metasoma ( Figs. 11 A, D). Carapace in lateral view teardrop-shaped ( Fig. 11 A); anteriorly with strong substrigulae that cross more than half the length of the carapace ( Fig. 11 D). Apex of carapace smooth, shiny and without tubercles. Ovipositor ( Fig. 11 A) length 0.97 mm . Carapace length 1.25 mm . Male.— Unknown. Biology.— Unknown.
