Description. Female. Body length 8.3–10.5 mm; fore wing length 6.3–7.2 mm.

Head width (dorsal view) 1.5–1.7 × its median length, 1.3–1.4 × maximum width of mesoscutum. Head behind eyes (dorsal view) roundly narrowed. Eye about 2.0 × longer than temple (dorsal view). Ocelli medium-sized, arranged in triangle with base 1.1–1.3 × its sides. POL 0.8–0.9 × Od, 0.3–0.4 × OOL. Frons weakly concave, with fine but distinct and long median longitudinal carina. Eye glabrous, 1.2 × higher than broad. Face width 0.8 × height of eye and 0.9–1.0 × height of face and clypeus combined. Malar space 0.2 × height of eye, 0.4 × basal width of mandible. Hypoclypeal depression width 0.9 × the shortest distance between depression and eye and 0.4 × width of face.

Antenna slender, almost filiform, with more than 52 antennomeres (apical flagellomeres missing). Scape 1.2– 1.4 × as long as its maximum width. First flagellomere 4.2–4.8 × longer than its apical width, 0.9 × longer than second flagellomere. Subapical flagellomeres 4.0–5.0 × longer than their maximum width.

Mesosoma 2.3 × longer than its maximum height. Pronotum distinctly convex dorsally (lateral view) and with fine submedian pronotal carina (dorsal view). Median lobe of mesoscutum distinctly protruding forwards and anteriorly weakly convex, without median longitudinal furrow. Notauli deep anteriorly and shallow posteriorly, crenulated. Median length of mesoscutum 1.1–1.2 × its maximum width. Prescutellar depression (scutellar sulcus) rather deep, finely crenulated, with three distinct carinae, 0.4 × as long as scutellum medially. Precoxal sulcus (sternaulus) absent.

Wings. Fore wing 4.1–4.5 × longer than maximum width. Vein r (first radial abscissa) arising from middle of pterostigma. Vein 3RSa (second radial abscissa) 1.5–1.7 × longer than vein r (first radial abscissa), 0.3 × as long as the straight vein 3RSb (third radial abscissa), 1.1 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell 2.3 × longer than maximum width, 0.6 × as long as first subdiscal (brachial) cell. Vein (RS+M)a (first medial abscissa) weakly sinuate. Vein 1m-cu (recurrent) almost interstitial, subparallel to vein 1M (basal). Vein 1cu-a (nervulus) postfurcal, 0.1–0.2 × as long as distance between veins 1M (basal) and 1cu-a (nervulus). Hind wing vein M+CU (first submedial abscissa) 0.3 × as long as vein 1-M (second submedial abscissa). Vein mcu (recurrent) almost straight and distinctly antefurcal.

Legs. Hind femur 4.0–4.3 × longer than maximum width. Hind tarsus about as long as hind tibia. Basitarsus of hind tarsus 1.0–1.1 × as long as second-fifth segments of hind tarsus combined. Second segment of hind tarsus 0.4 × as long as basitarsus, 1.7 × longer than fifth segment (without pretarsus).

Metasoma 1.5 × longer than mesosoma and head combined. First tergite without basolateral lobes and spiracular tubercles. Length of first tergite 1.1–1.2 × its maximum (subapical) width; maximum width 1.3–1.4 × its minimum (basal) width. Second tergite with distinct long and convergent sublateral furrows; median length of second tergite 0.9–1.0 × its basal width, 1.3–1.4 × median length of third tergite. Suture between second and third tergites entirely deep and rather wide, distinctly sinuate, with not strong sublateral bends. Third tergite with distinct wide transverse crenulated depression in basal third. Ovipositor sheath 1.3 × longer than metasoma, 2.7 × longer than mesosoma, 1.1 × longer than fore wing.

Sculpture and pubescence. Vertex smooth; frons partly smooth, with transverse curved striation; face coarse costate-rugose. Mesoscutum mainly smooth, rugose-reticulate in medioposterior triangle area. Mesopleuron and metapleuron mainly smooth. Propodeal basal areas distinctly delineated by carinae, rugulose-lacunose; areola not delineated by carinae, its area areolate-rugose. Hind coxa and femur mainly smooth. First metasomal tergite rugulose-lacunose; second tergite with semicircular area finely areolate-rugulose. Third tergite distinctly and densely areolate-rugose to areolate in basal 0.3 (medially)—0.6 (laterally) and smooth apically. Fourth-fifth tergites very densely areolate-rugose in basal halves, smooth on remaining parts. Vertex glabrous on wide area, with sparse short setae medioposteriorly. Mesoscutum with median lobe mostly glabrous, lateral lobes covered by dense short setae. Dorsal side of hind tibia with long, rather sparse and semi-erect pale setae, length of longest setae about equal to maximum width of tibia.

Colour. Head mainly black, sides of face and malar area brownish yellow. Palpi light yellow. Antenna black, scape dark brown and yellow apically, pedicel dark brown. Mesosoma orange. Tegula brown. Fore and mid legs mainly yellow, tarsi dark yellow, last tarsi light brown; mid coxa light brown, yellow basally, trochanter and femur light brown on basal third; hind leg dark brown, hind coxa, trochanter and trochantellus black. Metasoma black to brown, white laterally. Ovipositor sheath black. Wings distinctly infuscate. Pterostigma dark brown.

Male. Unknown.

Distribution. Ecuador, Brazil.

Etymology. Named in honour to Bororo people, one of the various indigenous ethnic groups that inhabited the region currently know as the state of Mato Grosso.

Comparative diagnosis. Pedinotus bororo sp. nov. has a mesoscutum mostly smooth with median and lateral lobes mostly glabrous but with rather dense setae along notauli, on postero-median area and laterally. This new species is morphologically similar to P. tundisii Felix et Penteado-Dias , but differs from it by having the precoxal sulcus short and shallow (long and deep in P. tundisii ), mesosoma brownish yellow (mostly dark brown in P. tundisii ), and ovipositor distinctly longer than metasoma (shorter in P. tundisii ). In comparison with P. columbianus Enderlein , its most similar species with densely and widely setose mesoscutum, P. bororo also has an entirely orange mesosoma (partly to mostly dark brown in P. columbianus ), and a median lobe smooth anteriorly (almost entirely punctate in P. columbianus ).
