First flagellomere 5.5–5.7 × longer than its apical width, 1.1–1.2 × longer than second flagellomere. Submedian flagellomeres 3.8 × longer than their width.

Mesosoma not depressed, its length 2.1 × its maximum height. Pronotum distinctly convex dorsally (lateral view) and with fine submedian pronotal carina (dorsal view). Median lobe of mesoscutum protruding forward (lateral view), its anterior margin weakly convex (dorsal view), without median longitudinal furrow. Median length of mesoscutum 1.0–1.1 × its maximum width. Notauli complete, deep anteriorly and shallow posteriorly, entirely crenulated. Prescutellar depression (scutellar sulcus) rather deep, almost smooth or weakly sculptured, with threefive distinct, coarse carinae, 0.3–0.4 × as long as scutellum medially. Precoxal sulcus (sternaulus) shallow but distinct, smooth, rather short, running along anterior 0.4–0.5 of lower part of mesopleuron.

Wings. Fore wing 3.8 × longer than its maximum width. Vein r (first radial abscissa) arising almost from middle of pterostigma. Vein 3RSa (second radial abscissa) 2.0–2.3 × longer than vein r (first radial abscissa), 0.3– 0.4 × as long as the straight vein 3RSb (third radial abscissa), 1.3–1.4 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell 2.3–2.4 × longer than its maximum width, 0.85 × as long as the rather wide first subdiscal (brachial) cell. Vein (RS+M)a (first medial abscissa) weakly sinuate. Vein 1m-cu (recurrent) weakly antefurcal, subparallel to vein 1M (basal). Vein 1cu-a (nervulus) postfurcal, 0.4–0.5 × as long as distance between veins 1M (basal) and nervulus (1cu-a). First subdiscal (brachial) cell 5.5 × longer than maximum width. Hind wing vein M+CU (first abscissa of mediocubital) 0.35–0.40 × as long as vein 1M (second abscissa). Vein m-cu (recurrent) almost straight and distinctly antefurcal.

Legs. Hind femur 3.4–3.7 × longer than maximum width. Hind tarsus about as long as 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, 1.4 × longer than fifth segment (without pretarsus).

Metasoma (missing in holotype) 1.1 × longer than mesosoma and head combined. First tergite without basolateral lobes lobes and spiracular tubercles, distinctly and linearly widened from subbase to apex. Length of first tergite 0.85 × its maximum (subapical) width; maximum width 1.7 × its minimum (basal) width. First and second tergites perhaps immovable fused, its suture dorsally rather deep and wide. Second tergite with wide, rather deep, almost parallel sublateral furrows. Median length of second tergite 0.3 × its basal width, 0.7 × median length of third tergite. Suture between second and third tergites entirely deep and rather wide, distinctly sinuate, with strong sublateral bends. Third tergite with distinct, wide and crenulated transverse sulcus in basal third. Ovipositor sheath 0.8 × as long as metasoma, 1.15 × longer than mesosoma, 0.5 × as long as fore wing.

Sculpture and pubescence. Vertex mainly smooth, sometimes with fine striations antero-laterally; frons finely curvedly transverse striate with reticulation laterally, almost smooth medio-anteriorly or latero-anteriorly; face coarsely rugose-striate, partly with dense granulation. Mesoscutum mainly smooth, sometimes very finely coriaceous on lateral lobes, with rather wide and coarse rugose-reticulate subtriangular area in medioposterior half. Mesopleuron mainly smooth, partly with very fine punctation. Metapleuron finely coriaceous or punctulate, rugulose-striate posteriorly on narrow area. Propodeal areas more or less distinctly delineated by carinae, basolateral areas at least partly smooth to almost smooth in anterior half and reticulate-areolate in posterior half or only densely punctate with rugosity along carinae; areola pentagonal, rugulose, about 1.5 × longer than wide; dorsal carina 0.6–1.0 × as long as anterior fork of areola. Hind coxa and femur mainly smooth, coriaceous dorsally. First and second metasomal tergites coarsely and sparsely striate-rugose. Third tergite distinctly and densely rugose-reticulate or reticulate-punctate in basal 0.3 (medially)–0.6 (laterally) and smooth apically. Fourth to sixth tergites very densely and small reticulate-punctate in basal halves, smooth on remaining parts. Vertex mainly glabrous, with a few sparse, short and semi-erect pale setae arranged on narrow lines laterally and posteriorly. Mesoscutum mainly glabrous, with short or very short, rather sparse and semi-erect pale setae arranged along notauli, on medioposterior sculptured area and laterally. Dorsal side of hind tibia with long, rather sparse and semierect pale setae, their length 0.5–0.9 × maximum width of tibia.

Colour. Head entirely yellow to brownish yellow (holotype) or mainly black, brownish yellow or light reddish brown in dorso-anterior ring of eye (non-type specimen), sides of face and on malar area. Palpi brownish, two-three apical segments yellow. Antennae black, two basal segments with brownish tint or scape brown in ventral half. Mesosoma entirely yellow to brownish yellow (holotype) or mainly black with mesopleuron, metapleuron and propodeum light reddish brown, pronotum brownish yellow on anterior and lateral narrow margins (non-type specimen). Tegula light reddish brown (holotype) or dark brown (non-type specimen). Legs in holotype mainly dark reddish brown, mid trochanter, two middle segments of fore tarsus and most segments (except dark fifth segment) of middle and hind tarsi yellow to brownish yellow; middle tibia basally yellow; legs in non-type specimen mainly black or almost black, all tarsi brown; subbasal belts of fore and hind tibiae paler, brown, but on middle leg whitish yellow. Metasoma light reddish brown to orange brown, darkened apically. Ovipositor sheath black. Wings faintly or very faintly and almost evenly infuscate. Pterostigma dark brown or almost black, very faintly pale basally and apically.

Male. Unknown.

Distribution. USA, Mexico, Costa Rica.

Comparative diagnosis. This new species belongs to the morphological group with glabrous mesoscutum. Pedinotus ferrugineus (Enderlein) is very similar to P. variegatus Marsh and P. cerdai sp. nov.; the differences between these species are shown after descriptions of the latter species.

Remarks. Discussion about relation of Pedinotus ferrugineus and P. variegatus is given after redescription of the latter species.
