Description. Female. Body length 5.4–6.4 mm; fore wing length 3.7–5.1 mm.

Head width (dorsal view) 1.3–1.4 × its median length, 1.0–1.2 × maximum width of mesoscutum; Head behind eyes (dorsal view) roundly narrowed. Eye 1.6–1.7 × longer than temple (dorsal view). Ocelli medium-sized, arranged in triangle with base 0.9–1.0 × as long as its sides, arranged in almost equilateral triangle. POL 1.2 × OD, 0.3 × OOL. Frons concave, with fine but distinct and long median longitudinal carina. Eye glabrous, 1.1–1.2 × higher than broad. Face width equal to height of eye and 1.2 × height of face and clypeus combined. Malar space 0.3 × height of eye, 1.5 × basal width of mandible. Hypoclypeal depression width 0.8 × the shortest distance between depression and eye and 0.4 × width of face.

Antenna slender, almost filiform, with more than 37 antennomeres (apical flagellomeres missing). Scape 1.35– 1.55 × longer than its maximum width. First flagellomere 4.0–5.0 × longer than its apical width, 1.2 × longer than second flagellomere. Submedian flagellomeres 3.1–4.6 × longer than their maximum width.

Mesosoma depressed, 2.6 × 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 complete, deep and smooth. Median length of mesoscutum 1.05–1.15 × its maximum width (dorsal view). Prescutellar depression (scutellar sulcus) deep, finely crenulated, with five distinct carinae, 0.4–0.5 × as long as scutellum medially. Precoxal sulcus (sternaulus) absent.

Wings. Fore wing 4.5–5.0 × longer than maximum width. Vein r (first radial abscissa) arising almost from middle of pterostigma. Vein 3RSa (second radial abscissa) 2.0 × longer than vein r (first radial abscissa), 0.3 × as long as the straight vein 3RSb (third radial abscissa), 1.8 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell 3.6 × longer than maximum width, 0.8 × as long as first subdiscal (brachial) cell. Vein (RS+M)a (first medial abscissa) weakly sinuate. Vein 1m-cu (recurrent) weakly antefurcal, subparallel to vein 1M (basal). Vein 1cu-a (nervulus) postfurcal, 0.2–0.3 × as long as distance between veins 1M (basal) and nervulus (1cu-a). Hind wing vein M+CU (first submedial abscissa) 0.3 × as long as vein 1-M (second submedial abscissa). Vein m-cu (recurrent) almost straight and distinctly interstitial to slightly antefurcal.

Legs. Hind femur 3.3–3.5 × longer than maximum width. Hind tarsus about 0.9 × as long as hind tibia. Basitarsus of hind tarsus 0.6–0.7 × as long as second-fifth segments of hind tarsus combined. Second segment of hind tarsus 0.5 × as long as basitarsus, 1.3 × longer than fifth segment (without pretarsus).

Metasoma as long as head and mesosoma combined. First tergite with basolateral lobes and spiracular tubercles, linearly widened from subbase to apex. Length of first tergite about 0.8 × its maximum (subapical) width; maximum width 1.3–1.4 × its minimum (basal) width. Second tergite with rather short parallel sublateral furrows; median length of second tergite 0.3–0.4 × its basal width, about 0.7 × median length of third tergite. Suture between second and third tergites entirely deep and rather wide. Third tergite with distinct transverse crenulated sulcus at basal third. Ovipositor sheath 0.7 × as long as metasoma, 1.0–1.1 × as long as mesosoma, 0.4– 0.5 × as long as fore wing.

Sculpture and pubescence. Vertex smooth; frons partly smooth, with transverse curved striation; face coarsely costate-rugose. Mesoscutum smooth, rugulose in medioposterior triangle area. Mesopleuron almost entirely smooth. Metapleuron mainly smooth, weakly rugose just posteriorly in one paratype. Propodeum with areas distinctly delineated by carinae, areola pentagonal and rugose; basomedian carina about as long as anterior fork of areola. Hind coxa and femur smooth. First and second metasomal tergites rugose; third tergite distinctly scrobiculate in basal 0.3 (medially)–0.6 (laterally) and smooth apically. Remaining tergites punctate basally and smooth apically. Vertex glabrous on wide area, with sparse short setae laterally. Mesoscutum mostly glabrous. Dorsal margin of hind tibia with long, rather sparse and semi-erect pale setae, their length 0.6–0.8 × maximum width of tibia.

Colour. Head mainly orange, vertex and frons black. Palpi pale yellow, last apical segment brownish. Antenna from dark brown to black, brownish apically. Mesosoma mainly black, metapleuron and propodeum reddish brown; propleuron and most of pronotum orange yellow. Tegula yellow. First and second metasomal tergites reddish brown at, black at border of first tergite and semicircular area of second tergite. Remaining tergites black basally and yellowish apically. Legs honey yellow, fore coxa and trochanter, mid trochanter and trochantellus white; fore and mid tarsi dark yellow, hind tarsus light brown; hind coxa black, hind trochanter and trochantellus light yellow, hind tibia marked with light brown. Ovipositor sheath black. Wings faintly and evenly infuscate. Pterostigma brown.

Male. Unknown.

Distribution. Brazil.

Etymology. This new species is named in honour of our hymenopterist colleague Fernando Noll, who collected the holotype.

Comparative diagnosis. This new species belongs to the morphological group with glabrous mesoscutum. Pedinotus nolli sp. nov. is morphologically similar to P. variegatus Marsh , but it differs from the latter species by having the second submarginal cell of fore wing long (short in P. variegatus ), mesosoma mostly dark brown with metapleuron and propodeum medially dark reddish brown (mesosoma mostly yellow or brownish yellow, propodeum usually dark brown or black in P. variegatus ), and precoxal sulcus absent (present but weak in P. variegatus ).
