First flagellomere 5.8–6.2 × longer than its apical width, 1.1 × longer than second flagellomere. Submedian flagellomeres about 4.0 × longer than their maximum width.

Mesosoma 2.4–2.5 × longer than its maximum height. Pronotum convex dorsally (lateral view), with distinct and rather high submedian pronotal carina (dorsal view). Median lobe of mesoscutum highly and roundly elevated above pronotum (lateral view), distinctly protruding forwards and anteriorly convex (dorsal view), without median longitudinal furrow; median length of mesoscutum 1.25–1.30 × its maximum width. Notauli complete, rather narrow, crenulated, deep anteriorly and shallow posteriorly, fused with large reticulate-areolate medioposterior subtriangular area. Prescutellar depression (scutellar sulcus) rather deep, long, with high four-six carinae, 0.25– 0.35 × as long as scutellum medially. Precoxal sulcus (sternaulus) very shallow but deeper medially, rather long, smooth, running along anterior 0.7 of lower part of mesopleuron.

Wings. Fore wing 4.3–4.6 × longer than maximum width. Vein r (first radial abscissa) arising almost from middle of pterostigma. Vein 3RSa (second radial abscissa) 1.3–1.5 × longer than vein r (first radial abscissa), 0.20– 0.25 × as long as the very weakly curved vein 3RSb (third radial abscissa), 1.0–1.4 × as long as vein 2RS (first radiomedial). Second submarginal (radiomedial) cell not widened apically, 2.0–2.3 × longer than maximum width, 0.5–0.6 × as long as first subdiscal (brachial) cell. Vein (RS+M)a (first medial abscissa) weakly sinuate. Vein 1mcu (recurrent) antefurcal, subparallel to vein 1M (basal). Vein 1cu-a (nervulus) interstitial or postfurcal, 0.1–0.3 × as long as distance between veins 1M (basal) and nervulus (1cu-a). First subdiscal (brachial) cell 6.0–6.5 × longer than maximum width. Hind wing vein M+CU (first submedial abscissa) 0.35–0.40 × as long as vein 1-M (second submedial abscissa). Vein m-cu (recurrent) straight and antefurcal.

Legs. Hind femur 3.9–4.3 × longer than maximum width. Hind tarsus 1.0–1.1 × longer than hind tibia. Basitarsus of hind tarsus about 0.8 × as long as second-fifth segments of hind tarsus combined. Second segment of hind tarsus 0.45–0.50 × as long as basitarsus, 1.8–1.9 × longer than fifth segment (without pretarsus).

Metasoma 1.45–1.60 × longer than mesosoma and head combined. First tergite with short and narrow basolateral lobes, without spiracular tubercles, weakly and almost linearly widened from subbase to apex. Length of first tergite 1.35–1.60 × its maximum (subapical) width; maximum width 1.4–1.5 × its minimum (basal) width. First and second tergites immovable fused, its suture dorsally rather shallow and narrow. Second tergite with narrow, very shallow, fine and almost parallel sublateral furrows; median length of second tergite almost equal to its basal width, 1.25–1.40 × median length of third tergite. Suture between second and third tergites evenly deep, narrow, weakly sinuate, weakly and widely convex medially, with weak sublateral bends. Third tergite with rather distinct, wide, shallow sinuate crenulated transverse sulcus submedially. Ovipositor sheath (partly broken in holotype and 1 paratype) 1.3 × longer than metasoma, 2.3 × longer than mesosoma, 0.75 × as long as body, 1.25 × longer than fore wing.

Sculpture and pubescence. Vertex smooth; frons striate medially, smooth or almost smooth laterally and posteriorly; face coarsely transverse striate, rugose-reticulate medially, with dense and fine rugosity between striae and rugae. Mesoscutum mainly smooth, coarsely reticulate-rugose in medioposterior subtriangle area. Mesopleuron smooth. Metapleuron mainly smooth, but finely coriaceous-punctate marginally, transverse striate or rugulose posteriorly. Propodeal areas not delineated by carinae, propodeum entirely densely reticulate-areolate, but finer basally, with short basomedian carina in basal quarter or third. Hind coxa and femur mainly smooth, coriaceous dorsally. First metasomal tergite coarsely undulately longitudinally striate with distinct reticulation. Second to sixth tergites mainly very dense and small reticulate-areolate to punctate, second tergite sometimes with additional striation at least medially, fourth to sixth tergites smooth on narrow apical parts; sculpture becoming finer toward apex of metasoma. Vertex with very sparse, long and almost erect pale setae, glabrous in sublateral and anterior parts. Mesoscutum mainly glabrous, with rather long or short, sparse and semi-erect pale setae arranged widely on anterolateral corner of median lobe and narrowly along notauli and laterally. Dorsal side of hind tibia with long, rather dense and semi-erect pale setae, their length 0.6–0.9 × maximum width of tibia.

Colour. Head black. Palpi brownish yellow. Antenna entirely black. Mesosoma light reddish brown to brownish yellow. Tegula brownish yellow or yellow. Metasoma light reddish brown to brownish yellow in basal half and reddish brown to black in apical half. Fore and mid legs brownish yellow; hind leg mainly dark brown to black, hind coxa brownish yellow, hind tibia brownish yellow or yellow on short subbasal distance. Ovipositor sheath dark brown to black. Wings entirely faintly and evenly infuscate. Pterostigma entirely dark brown.

Male. Unknown.

Distribution. French Guiana.

Etymology. This species is named after its elongated body and metasomal tergites.

Comparative diagnosis. This new species belongs to the morphological group with glabrous mesoscutum. Pedinotus elongatus sp. nov. is morphologically similar to P. nigriceps sp. nov., but differs from the latter species by having the suture between second and third tergites less distinctly curved medially and with weak sublateral breaks (more distinctly curved medially and with distinct sublateral breaks in P. nigriceps ), fore wing faintly darkened (distinctly darkened in P. nigriceps ), palpi entirely pale (mainly dark in P. nigriceps ), and notauli crenulated in anterior half (smooth in P. nigriceps ). Also, the new species is similar to P. haliti sp. nov.; the differences between these two species are shown in the description of P. haliti .
