Head sometimes (holotype) weakly depressed (holotype) or not depressed (paratype), width 1.3–1.5 × its median length, 1.2 × maximum width of mesoscutum. Head behind eyes (dorsal view) roundly narrowed. Eye 2.0 × longer than temple (dorsal view). Ocelli medium-sized, arranged in triangle with base 1.15–1.20 × its sides, anterior round ocellus weakly smaller than lateral oval ocelli. POL 0.8–1.0 × Od, 0.4 × OOL. Frons very weakly concave, with distinct and rather high median longitudinal carina between antennal sockets. Eye glabrous, 1.2 × higher than broad. Face width 0.70–0.75 × height of eye and 0.9–1.1 × height of face and clypeus combined. Malar space 0.2–0.3 × height of eye, 0.5–0.7 × basal width of mandible. Hypoclypeal depression width 1.0–1.1 × the shortest distance between depression and eye and about 0.5 × width of face.

First flagellomere 5.5–6.0 × longer than its apical width, almost as long as second flagellomere. Submedian flagellomeres 4.5–5.0 × longer than their maximum width.

Mesosoma weakly depressed, its length 2.4–2.7 × maximum height. Pronotum distinctly convex dorsally (lateral view), with fine submedian pronotal carina (dorsal view). Median lobe of mesoscutum not highly and roundly elevated above pronotum (lateral view), distinctly protruding forwards and distinctly convex anteriorly (dorsal view), without median longitudinal furrow. Median length of mesoscutum 1.3 × its maximum width. Notauli complete, wide, crenulated, deep anteriorly and shallow posteriorly, fused with large medioposterior sculptured subrectangular area. Prescutellar depression (scutellar sulcus) rather shallow, long, with distinct fiveseven carinae, 0.3 × as long as scutellum medially. Precoxal sulcus (sternaulus) shallow, more or less distinct, rather long, smooth, running along anterior 0.7 of lower part of mesopleuron.

Wings. Fore wing 3.9–4.1 × longer than maximum width. Vein r (first radial abscissa) arising from middle of pterostigma. Vein 3RSa (second radial abscissa) 1.8–1.9 × longer than vein r (first radial abscissa), 0.3 × as long as the almost straight vein 3RSb (third radial abscissa), 1.7–1.8 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell not widened apically, 2.2–2.3 × longer than maximum width, 0.7–0.8 × as long as first subdiscal (brachial) cell. Vein (RS+M)a (first medial abscissa) sinuate. Vein 1m-cu (recurrent) 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). First subdiscal (brachial) cell 4.6–5.3 × longer than maximum width. Hind wing vein M+CU (first submedial abscissa) 0.30–0.35 × as long as vein 1-M (second submedial abscissa). Vein m-cu (recurrent) straight and antefurcal.

Legs. Hind femur 3.2–3.4 × longer than maximum width. Hind tarsus 1.1 × longer than hind tibia. Basitarsus of hind tarsus 0.7 × as long as second-fifth segments of hind tarsus combined. Second segment of hind tarsus 0.5 × as long as basitarsus, 1.6–1.7 × longer than fifth segment (without pretarsus).

Metasoma 1.2–1.3 × as long as mesosoma and head combined. First tergite with short subpointed basolateral lobes, without spiracular tubercles, weakly and almost linearly widened from subbase to apex. Length of first tergite 1.1–1.2 × its maximum (subapical) width; maximum width 1.6–1.7 × its minimum (basal) width. First and second tergites perhaps immovable fused, its suture dorsally shallow. Second tergite with wide, shallow, almost parallel sublateral furrows; median length of second tergite 0.5–0.6 × its basal width, 0.9 × median length of third tergite. Suture between second and third tergites entirely deep, rather narrow, distinctly sinuate, with rather strong sublateral bends. Third tergite with distinct narrow transverse crenulated sulcus in basal 0.4–0.5. Ovipositor sheath 0.8–1.0 × as long as metasoma, 1.5–1.6 × longer than mesosoma, 0.8 × as long as fore wing.

Sculpture and pubescence. Vertex smooth; frons transversely striate in anterior half and almost smooth in posterior half; face coarsely transversely striate with reticulation, rugose-areolate with granulation medially. Mesoscutum mainly smooth, coarsely rugose-reticulate in large medioposterior subrectangular area. Mesopleuron mainly smooth. Metapleuron finely reticulate-punctate, with transverse curved striation posteriorly. Propodeum usually without areas delineated by carinae, basolateral areas entirely distinctly and densely rugulose-punctate; areola not delineated; basomedian carina situated in basal half of propodeum. Hind coxa and femur smooth. First and second metasomal tergites coarsely striate with dense reticulation and granulation. Third to six tergites very densely areolate-rugose with fine and dense granulation in basal 0.7–0.5, sculpture becoming finer toward apex of metasoma, apical part of tergites smooth. Vertex mainly glabrous, with several very sparse long setae laterally. Mesoscutum mainly glabrous, with short, rather dense and semi-erect pale setae arranged widely along notauli and on margins of sculptured medioposterior area and narrow laterally. Dorsal side of hind tibia with long, rather dense and semi-erect pale setae, their length 0.8–1.1 × maximum width of tibia.

Colour. Head and mesosoma brownish yellow to light reddish brown, propodeum distinctly infuscate laterally and posteriorly. Palpi distinctly infuscate, brown. Antenna mainly black, scape and pedicel dark reddish brown. Tegula yellowish brown. Legs mainly brownish yellow or yellow, fore and hind tarsi brownish, apices of all femora distinctly infuscate, hind tibia dark brown, yellow or whitish yellow basally. Metasoma reddish brown, dark reddish brown on three basal tergites. Ovipositor sheath entirely dark brown. Wings entirely faintly infuscate. Pterostigma entirely dark brown.

Male. Unknown.

Distribution. French Guiana.

Etymology. This species is named after its entirely sculptured propodeum.

Comparative diagnosis. This new species belongs to the morphological group with glabrous mesoscutum. Pedinotus propodealis sp. nov. is morphologically similar to P. intermedius sp. nov., but it differs from the latter species by having the basolateral areas of propodeum entirely sculptured (smooth in basal 0.3–0.5 in P. intermedius ), mesosoma rather distinctly depressed (not depressed in P. intermedius ), posteromedian sculptured area on mesoscutum larger and subrectangular (smaller and subtriangular in P. intermedius ), and most part of hind femur brownish yellow (dark reddish brown in P. intermedius ).
