Ocelli medium-sized, arranged in triangle with base 1.15–1.25 × its sides, anterior ocellus round and smaller than oval lateral ocelli. POL 0.7 × Od, 0.3 × OOL. Frons weakly concave, with fine but distinct median longitudinal carina between antennal sockets. Eye glabrous, 1.15–1.20 × higher than broad. Face width 0.8 × height of eye and 0.95 × height of face and clypeus combined. Malar space 0.3 × height of eye, 0.7 × basal width of mandible. Hypoclypeal depression width almost equal to the shortest distance between depression and eye and about 0.5 × width of face.
Antenna slender, almost filiform, with more than 37 antennomeres (apical flagellomeres missing). Scape 1.6– 1.7 × longer than its maximum width. First flagellomere 5.8–6.0 × longer than its apical width, 1.1 × longer than second flagellomere. Submedian and subapical flagellomeres 4.0–4.7 × longer than their maximum width.
Mesosoma 2.1 × longer than its maximum height. Pronotum distinctly convex dorsally (lateral view) and with distinct submedian pronotal carina (dorsal view). Median lobe of mesoscutum not highly and roundly elevated above pronotum (lateral view), distinctly protruding forwards and convex anteriorly (dorsal view), without median longitudinal furrow; median length of mesoscutum 1.15 × its maximum width. Notauli complete, wide, crenulated, deep anteriorly and shallow posteriorly, fused with large medioposterior sculptured subrectangular area. Prescutellar depression (scutellar sulcus) rather deep, long, with three distinct carinae, 0.25–0.30 × as long as scutellum medially. Precoxal sulcus (sternaulus) shallow, but distinct or almost distinct, rather short, smooth, running along anterior 0.5–0.6 of lower part of mesopleuron.
Wings. Fore wing 3.9–4.0 × longer than maximum width. Vein r (first radial abscissa) arising almost from middle of pterostigma. Vein 3RSa (second radial abscissa) 1.7–1.8 × longer than vein r (first radial abscissa), about 0.3 × as long as the weakly curved vein 3RSb (third radial abscissa), 1.3 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell weakly widened apically, 2.2 × longer than maximum width, 0.7–0.8 × as long as first subdiscal (brachial) cell. Vein (RS+M)a (first medial abscissa) weakly sinuate. Vein 1m-cu (recurrent) antefurcal, subparallel to vein 1M (basal). Vein 1cu-a (nervulus) postfurcal, 0.3–0.6 × as long as distance between veins 1M (basal) and nervulus (1cu-a). First subdiscal (brachial) cell 4.8–5.5 × longer than maximum width. Hind wing vein M+CU (first submedial abscissa) 0.4 × as long as vein 1-M (second submedial abscissa). Vein m-cu (recurrent) straight and weakly antefurcal.
Legs. Hind femur 3.4–3.5 × longer than maximum width. Hind tarsus 1.1 × 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, 1.4 × longer than fifth segment (without pretarsus).
Metasoma 1.0–1.1 × as long as mesosoma and head combined. First tergite with short subround basolateral lobes, without spiracular tubercles, distinctly and almost linearly widened from subbase to apex. Length of first tergite 0.8–0.9 × its maximum (subapical) width; maximum width 1.7–1.8 × its minimum (basal) width. First and second tergites immovable fused, its suture dorsally shallow. Second tergite with rather narrow, shallow, almost parallel sublateral furrows; median length of second tergite 0.45–0.50 × its basal width, 0.8–0.9 × median length of third tergite. Suture between second and third tergites entirely deep and rather wide, weakly sinuate, with weak sublateral bends. Third tergite with distinct wide transverse crenulated sulcus in basal 0.4. Ovipositor sheath almost 0.8 × as long as metasoma, 1.0–1.2 × as long as mesosoma, 0.5–0.6 × as long as fore wing.
Sculpture and pubescence. Vertex smooth; frons entirely transversely striate with reticulation, sometimes striation weak; face coarsely transversely curvedly striate, with dense rugosity between striae and medially. Mesoscutum mainly smooth, sometimes very finely coriaceous on lateral lobes, coarsely rugose-reticulate with striation in large medioposterior subrectangular area. Mesopleuron mainly smooth. Metapleuron finely coriaceous, with subtransverse striation and reticulation posteriorly. Propodeal areas rather distinctly delineated by carinae, basolateral areas densely rugulose-punctate with additional short striation along carinae, areola pentagonal and areolate; basomedian carina about as long as anterior fork of areola. Hind coxa and femur mainly almost smooth, coriaceous dorsally. First metasomal tergite coarsely and densely reticulate-areolate, striate at short area posteriorly. Second tergite densely striate with dense reticulation between striae. Third to sixth tergites almost entirely very densely and small reticulate-areolate to punctate, but sculpture finer toward apex of all tergites and almost smooth just along posterior margins. Vertex mainly glabrous on wide area, with sparse short setae medioposteriorly. Mesoscutum mainly glabrous, with short, rather dense and semi-erect pale setae arranged along notauli and on sculptured medioposterior area. Dorsal side of hind tibia with long, rather sparse and semi-erect pale setae, their length 0.8–1.0 × maximum width of tibia.
Colour. Body brownish yellow, faintly darker dorsally. Palpi brownish yellow. Antenna mainly black, scape reddish brown, with pale spot. Tegula yellow. Legs mainly brownish yellow or pale brown, all tarsi (except sometimes mainly yellow fore one) brown to dark brown with distinctly pale third and fourth segments; hind tibia dark brown, faintly paler apically, pale yellow in short basal area; fore tibia more or less distinctly dark basally, mid tibia pale basally. Ovipositor sheath entirely black. Wings entirely faintly and evenly infuscate. Pterostigma entirely black.
Male. Unknown.
Distribution. Colombia, French Guiana.
Etymology. Named after Mr J.A. Cerda, the collector of the holotype.
Comparative diagnosis. This new species belongs to the morphological group with glabrous mesoscutum. Pedinotus cerdai sp. nov. distinctly differs from the morphologically similar P. ferrugineus (Enderlein) and P. variegatus Marsh by having the suture between second and third tergites weakly sinuate with its sublateral bands widely separated from the anterior margin of tergite (strongly sinuate and with sublateral bands closely situated to anterior margin of tergite in P. ferrugineus and P. variegatus), the first tergite longer (shorter in P. ferrugineus and P. variegatus), and the fourth-sixth tergites almost entirely sculptured (smooth on posterior 0.25–0.30 in P. ferrugineus and P. variegatus).
