Median lobe of mesoscutum highly and roundly elevated above pronotum (lateral view), distinctly protruding forwards, anteriorly convex (dorsal view), without median longitudinal furrow but with shallow medioanterior depression. Median length of mesoscutum 1.0–1.1 × its maximum width. Notauli complete, deep anteriorly and shallow posteriorly, crenulated. Prescutellar depression (scutellar sulcus) rather deep, finely crenulated, with distinct six to eight carinae, 0.3–0.4 × as long as scutellum medially. Precoxal sulcus (sternaulus) shallow and smooth, weakly impressed to virtually absent, running along anterior 0.5 of lower part of mesopleuron.

Wings. Fore wing 3.2–4.1 × longer than maximum width. Vein r (first radial abscissa) arising from or near middle of pterostigma. Vein 3RSa (second radial abscissa) 1.7–2.1 × longer than vein r (first radial abscissa), about 0.3 × as long as the straight vein 3RSb (third radial abscissa), 1.2–1.5 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell not widened apically, 1.6–2.6 × longer than maximum width, 0.6–0.8 × as long as first subdiscal (brachial) cell. Vein (RS+M)a (first medial abscissa) weakly sinuate. Vein 1m-cu (recurrent) almost interstitial to antefurcal, subparallel to vein 1M (basal). Vein 1cu-a (nervulus) postfurcal, 0.1–0.2 × as long as distance between veins 1M (basal) and nervulus (1cu-a). Hind wing vein M+CU (first submedial abscissa) 0.4 × as long as vein 1-M (second submedial abscissa). Vein m-cu (recurrent) almost straight and antefurcal.

Legs. Hind femur 3.3–4.2 × longer than maximum width. Hind tarsus about as long as hind tibia. Basitarsus of hind tarsus 0.8–0.9 × as long as second-fifth segments of hind tarsus combined. Second segment of hind tarsus 0.5 × as long as basitarsus, 1.8–2.0 × longer than fifth segment (without pretarsus).

Metasoma 1.4–1.5 × longer than mesosoma and head combined. First tergite with basolateral lobes and spiracular tubercles, almost parallel-sided or weakly curvedly widened from subbase to apex. Length of first tergite 1.0–1.1 × its maximum (subapical) width; maximum width 1.4–1.6 × its minimum (basal) width. First and second tergites perhaps immovable and fused. Second tergite with rather long, wide, convergent sublateral furrows. Median length of second tergite 0.5–0.7 × its basal width, nearly equal to median length of third tergite. Suture between second and third tergites deep laterally and shallow medially, rather narrow, strongly sinuate, distinctly and rather narrowly convex medially, with strong sublateral bends. Third tergite with distinct wide transverse crenulated sulcus in basal 0.3 (medially)–0.5 (laterally). Ovipositor sheath 1.55–1.90 × longer than metasoma, 3.0– 3.6 × longer than mesosoma, 0.9–1.0 × as long as body, 1.3 × longer than fore wing.

Sculpture and pubescence. Vertex smooth; frons partly smooth and partly with transverse curved striation laterally and medially; face coarsely rugose and with dense transverse striation. Mesoscutum mainly smooth, coarsely transversely striate in medioposterior subquadrangular area. Mesopleuron mainly smooth. Metapleuron smooth, rugose posteriorly. Basolateral areas of propodeum distinctly delineated by carinae, smooth, but rugose along carinae; areola pentagonal and rugulose; basomedian carina 0.7–0.8 × as long as anterior fork of areola. Hind coxa and femur smooth. First metasomal tergites rugulose-lacunose or coarsely and densely reticulate-areolate, with oblique striation in posterolateral corners. Second tergite with costate semicircular area. Third tergite with distinct, smooth and polished midio-basal area covered by distinctly and densely rugose-reticulate sculpture in basal 0.3 (medially)–0.6 (laterally), smooth apically. Fourth to sixth tergites rugulose-lacunose in basal 0.5, smooth on remaining parts. Vertex glabrous on wide area, with sparse setae medioposteriorly and laterally. Mesoscutum mostly glabrous, with short and semi-erect pale setae laterally, along notauli and on medioposterior area. Dorsal side of hind tibia with long, rather dense and semi-erect pale setae, their length 0.8–1.5 × maximum width of tibia.

Colour. Head mainly black, with brownish yellow malar space, lower half of temple, clypeus and two small spots on sides of frons. Palpi pale yellow. Antenna black. Mesosoma mainly black, mesopleuron ventrally, metapleuron dorsally and propodeum orange, pronotum yellow ventrally. Tegula yellow. Metasoma with first and second tergites dark brown, remaining tergites dark brown basally and light brown apically. Legs mainly dark brown to black, all tarsi brown; fore coxa honey yellow, trochanter and trochantellus light yellow or light reddish brown, femur apically light brown; mid coxa light brown basally, trochanter and trochantellus pale brown, femur yellowish apically, bases of all tibiae almost white in specimen from French Guiana. Ovipositor sheath entirely black. Wings distinctly evenly infuscate. Pterostigma dark brown.

Male. Unknown.

Distribution., French Guiana, Brazil.

Etymology. Named in honour of the German entomologist Fritz Plaumann, who collected most of the type specimens.

Comparative diagnosis. This new species belongs to the morphological group with glabrous mesoscutum. Pedinotus plaumanni sp. nov. differs from other species with glabrous mesoscutum by very long ovipositor (which is about as long as body and more than 3.0 × longer than mesosoma), the presence of subquadrate yellow spot in medio-posterior strongly transversely costate half of mesoscutum, and the presence of a smooth and polished midbasal area on third metasomal tergite.
