Median lobe of mesoscutum not highly but distinctly and roundly elevated above pronotum (lateral view), distinctly protruding forwards and weakly convex anteriorly (dorsal view), without median longitudinal furrow. Median length of mesoscutum 1.10– 1.15 × its maximum width. Notauli complete, wide, crenulated, deep anteriorly and shallow posteriorly, fused with rather large medioposterior sculptured subtriangular area. Prescutellar depression (scutellar sulcus) rather deep, long, with three distinct carinae, 0.3–0.4 × as long as scutellum medially. Precoxal sulcus (sternaulus) shallow, more or less distinct, short, smooth, running along anterior 0.5 of lower part of mesopleuron.

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) 1.8–2.3 × longer than vein r (first radial abscissa), 0.30–0.35 × as long as the weakly curved or almost straight vein 3RSb (third radial abscissa), 1.5–1.7 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell not widened apically, 2.5–2.9 × longer than maximum width, 0.8–0.9 × 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 5.1–5.3 × longer than maximum width. Hind wing vein M+CU (first submedial abscissa) 0.3–0.4 × as long as vein 1-M (second submedial abscissa). Vein m-cu (recurrent) straight and weakly antefurcal.

Legs. Hind femur 3.4–3.7 × longer than maximum width. Hind tarsus 1.15 × longer than 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, 1.5 × longer than fifth segment (without pretarsus).

Metasoma 1.1 × as long as mesosoma and head combined. First tergite with very short rounded basolateral lobes, without spiracular tubercles, weakly and almost linearly widened from subbase to apex. Length of first tergite 1.10–1.15 × its maximum (subapical) width; maximum width 1.5–1.6 × its minimum (basal) width. First and second tergites perhaps immovable fused, its suture dorsally shallow. Second tergite with narrow, shallow, almost parallel sublateral furrows; median length of second tergite 0.45–0.50 × its basal width, 0.8 × median length of third tergite. Suture between second and third tergites entirely deep, rather wide, distinctly sinuate, with rather strong sublateral bends. Third tergite with distinct wide transverse crenulated sulcus in basal 0.4–0.5. Ovipositor sheath 1.10–1.15 × longer than metasoma, 1.8–1.9 × longer than mesosoma, 0.9 × as long as fore wing.

Sculpture and pubescence. Vertex smooth; frons transverse or oblique striate near ocelli and medially, smooth on wide lateral or sublateral areas; face coarsely transversely striate, rugose-areolate medially, only granulate on narrow median stripe, with dense fine rugulosity between striae. Mesoscutum mainly smooth, coarsely rugosereticulate in large medioposterior subtriangular area. Mesopleuron mainly smooth. Metapleuron very finely reticulate-punctate, with transverse curved striation posteriorly. Propodeum with areas more or less distinctly delineated by carinae, basolateral areas smooth in latero-anterior 0.3–0.5, distinctly and densely rugulose-punctate or rugose-punctate with additional short striation along carinae in latero-posterior halves; areola pentagonal and entirely areolate-reticulate; basomedian carina 0.8–1.0 × as long as anterior fork of areola. Hind coxa and femur smooth. First metasomal tergite coarsely and densely reticulate-areolate, sometimes with additional undulate curved striation postero-laterally. Second tergite striate with dense reticulation between striae, only very dense and small reticulate-areolate laterally. Third to six tergites very densely and small areolate-punctate in basal 0.4–0.6, but sculpture becoming finer toward apex of metasoma, rest apical parts of tergites smooth. Vertex mainly glabrous, with several very sparse long setae laterally and posteriorly. Mesoscutum mainly glabrous, with short or partly very short, rather dense and semi-erect pale setae arranged widely along notauli and on sculptured medioposterior area and narrowly laterally. Dorsal side of hind tibia with long, rather dense and semi-erect pale setae, their length 0.8–1.0 × maximum width of tibia.

Colour. Head brownish yellow, faintly darker dorsally. Palpi brownish yellow or yellow. Antenna dark brown to black, scape and pedicel brown. Mesosoma brownish yellow to yellow, entirely or widely reddish brown to dark reddish brown dorsally. Metasoma brown to reddish brown in basal half and pale brown to brownish yellow in apical half, sometimes mainly dark reddish brown to black and paler apically, tergites laterally whitish yellow or almost white, apical margins of third-seventh tergites paler, furrows and sutures in basal half of metasoma yellow. Tegula yellow. Fore and mid legs brownish yellow or yellow, femora brown in basal half and apically, tibiae mainly light reddish brown. Hind leg mainly brown, hind coxa, middle part of femur and narrow subbasal short ring of hind tibia brownish yellow to pale yellow, middle segments of hind tarsus paler. Ovipositor sheath entirely dark brown. Wings entirely faintly or very faintly infuscate. Pterostigma entirely dark brown.

Male. Unknown.

Distribution. French Guiana.

Etymology. Named after its intermediate combination of morphological characters.

Comparative diagnosis. This new species belongs to the morphological group with glabrous mesoscutum. Pedinotus intermedius sp. nov. is morphologically similar to P. dispar sp. nov., but it differs from the latter species by having the lateral bends of second suture less strong with maximum median length of second tergite 1.4–1.5 × its minimum sublateral length (lateral bends of second suture more strong with maximum median length of second tergite 2.0–2.3 × its minimum sublateral length in P. dispar ), hind coxa of female yellow (black in P. dispar ), and subbasal yellow area on hind tibia rather long (very short or indistinct in P. dispar ).
