Eye weakly concave opposite antennal sockets, 1.20–1.25 × higher than broad. Malar space height 0.20–0.25 × height of eye, 0.45–0.50 × basal width of mandible. Face convex, its width 0.65–0.85 × height of eye and 0.9–1.1 × height of face and clypeus combined. Hypoclypeal depression subround, its width 1.1–1.3 × the shortest distance from edge of depression to eye, 0.5–0.6 × width of face.

Antenna slender, weakly setiform, with more than 33 antennomeres (apical flagellomeres missing in all specimens). Scape 1.3–1.4 × longer than its maximum width. First flagellomere 5.5–7.0 × longer than its apical width, about as long as second flagellomere.

Mesosoma more or less distinctly depressed, its length 2.2–3.0 × maximum height. Median lobe of mesoscutum protruding forward and convex (lateral view), its anterior margin more or less distinctly convex (dorsal view). Median length of mesoscutum 1.2–1.3 × its maximum width. Notauli entirely rugose. Prescutellar depression shallow, crenulate-rugulose, with five carinae, 0.30–0.35 × as long as scutellum. Scutellum almost flat, without lateral carinae. Precoxal sulcus (sternaulus) distinct, but sometimes shallow, usually crenulated, running along anterior 0.5–0.6 of lower part of mesopleuron.

Wings. Fore wing 4.0–4.2 × longer than its maximum width. Vein r (first radial abscissa) arising distinctly before middle of pterostigma. Vein R1a (metacarp) 1.3–1.5 × longer than pterostigma. Vein 3RSa (second radial abscissa) 1.5–2.0 × 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 2.3–2.9 × longer than its maximum width, 0.75 × as long as rather narrow first subdiscal (brachial) cell. Distance from vein cu-a (nervulus) to vein 1M (basal) 0.4–0.6 × vein cu-a (nervulus) length. Hind wing vein M+CU (first abscissa of mediocubital) 0.3 × as long as vein 1M (second abscissa). Vein m-cu (recurrent) distinctly antefurcal, almost straight.

Legs. Hind femur 3.8–4.0 × longer than width. Hind tarsus 1.1–1.2 × longer than hind tibia. Second segment of hind tarsus 0.45–0.50 × as long as basitarsus, 1.45–1.60 × longer than fifth segment (without pretarsus).

Metasoma 1.3–1.4 × longer than head and mesosoma combined. First tergite weakly and almost evenly sublinearly widened towards subapex, weakly narrowed apically. Length of first tergite 1.1–1.2 × its maximum (subapical) width; maximum width 1.6–1.8 × its minimum (basal) width. Median length of second tergite 0.70– 0.75 × its basal width, 1.2–1.4 × median length of third tergite; maximum median length of second tergite 1.3–1.5 (sometimes 1.7) × its minimum sublateral length (at level of breaks). Ovipositor sheath 0.5–0.6 × as long as body, 0.85–1.10 × as long as metasoma, 0.70–0.85 × as long as fore wing.

Sculpture and pubescence. Vertex and temple smooth; frons rugulose at least in anterior half; face coarsely rugose-areolate with striation. Mesoscutum densely and distinctly punctate with reticulation, but rarely punctation laterally and anteriorly fine and sparse, with wide and coarse rugose-reticulate with striation area in medioposterior 0.5–0.7. Mesopleuron in lower half almost entirely smooth. Metapleuron entirely reticulate-punctate, usually finer in anterior half. Propodeum without or with finely delineated areas, entirely densely and small rugulose-reticulate, with median dorsal carina in basal half. First metasomal tergite entirely densely rugose-reticulate, sometimes with undulate longitudinal striation at least laterally. Second tergite entirely and densely small reticulate-areolate. Third tergite in basal 0.6–0.7, fourth to sixth or four to fifth tergites in basal 0.5–0.2 densely or very densely and small areolate-punctate or punctate, smooth on other parts. Vertex mainly glabrous, with sparse setae laterally and posteriorly. Mesoscutum almost entirely or widely in dense or very dense, short and semi-erect white setae, usually glabrous anteriorly on median lobe and rarely medially on lateral lobes. Hind tibia dorsally with sparse, semi-erect and medium length pale setae, length of these setae 0.8–1.2 × maximum width of hind tibia.

Colour. Head mainly dark reddish brown, light reddish brown at least partly laterally and below or widely except almost black the most part of frons and vertex. Palpi yellow. Antenna reddish brown to dark reddish brown or black, scape and pedicel light reddish brown with brown lateral or dossal spots or at least weakly paler. Mesosoma mainly black or dark reddish brown, often light reddish brown to yellow laterally and sometimes anteriorly or posteriorly, usually light brown or reddish brown below. Legs light reddish brown, sometimes with wide dark spots, fore and sometimes mid coxae and trochanters yellow; hind coxa mainly black, femur, tibia and tarsus light reddish brown to dark reddish brown with almost black spots. Metasoma dark reddish brown to black, with pale reddish brown sides and sutures; posterior halves of third-sixth tergites paler. Ovipositor sheath almost entirely black, usually paler basally. Wings faintly and almost evenly infuscate. Pterostigma dark brown or brown, usually faintly paler apically.

Male. Unknown.

Distribution. Colombia, French Guiana, Brazil.

Comparative diagnosis. This species belongs to the morphological group with mainly and densely setose mesoscutum. Pedinotus brasiliensis is very similar to P. columbianus Enderlein ; the differences between these species are shown in the key.

Remarks. One specimen from Colombia (female, CNIN 1465; GenBank accession no. KT851884 ) was correctly determined by E. Samacá-Sáenz as P. brasiliensis Szépligeti (according to label on the pin under specimen), but in Samacá-Sáenz et al.’s the phylogenetic tree (2016: 486) it was erroneously named as P. columbianus .
