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.

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.
