Length of first tergite 0.8–1.0 × its maximum (subapical) width; maximum width 1.4–1.5 × its minimum (basal) width. Second tergite with rather short and wide sublateral furrows; median length of second tergite 0.6–0.7 × its basal width, about equal to median median length of third tergite.

Ovipositor sheath 1.0–1.1 × as long as metasoma, 1.4–1.5 × longer than mesosoma, 0.6–0.8 × as long as fore wing.

Sculpture and pubescence. Vertex smooth; frons finely transversely striate, with almost smooth lateral stripes; face coarsely areolate-rugose with striae near clypeus. Mesoscutum densely and distinctly punctate, with wide and coarsely rugose area in medioposterior half. Mesopleuron polished below, dorsally punctate to coarsely punctatereticulate anteriorly. Metapleuron smooth to weakly reticulate-punctate, posteriorly rugulose. Propodeum without delineated areas, entirely areolate-rugulose, with median carina in basal half. First metasomal tergite entirely areolate-rugulose. Second tergite coarsely areolate-rugose. its lateral areas almost smooth. Third tergite crenulated before and just apical to sulcus, smooth posteriorly. Fourth to sixth tergites very densely and small reticulateareolate in basal 0.5–0.3, smooth on other parts. Vertex mainly glabrous. Mesoscutum almost entirely in very dense, short and semi-erect white setae, mesosoma laterally covered by dense white setae. Hind tibia dorsally with sparse, semi-erect and medium length pale setae, length of these setae slightly shorter than width of hind tibia.

Colour. Head yellow, ocelli black. Scape and pedicel light yellow to light brown; flagellum black, but dark brown basally. Mesosoma black, except subalar groove light brown. Tegula light yellow. Legs mainly light brown, except a whitish stripe on femora; fore and mid coxae, trochanters and trochantelli whitish; hind coxa black, but white apically, mid and hind tibia white basally. Metasoma black, white laterally. Ovipositor sheath entirely dark brown.

Eye 1.3–1.4 × longer than temple (dorsal view). Frons weakly concave. Antenna with 33 antennomeres. Length of mesosoma 2.4–2.6 × its maximum height. Precoxal sulcus (sternaulus) present and almost complete, rather shallow and weakly crenulated. Propodeum with median and lateral longitudinal carinae present partly. Fore wing vein 3RSa (second radial abscissa) about 2.0 × longer than vein r (first radial abscissa), 0.3 × as long as vein 3RSb (third radial abscissa), 1.3 × longer than vein 2RS (first radiomedial). Hind femur 3.5 × longer than maximum width. Metasoma narrow, with fourth to sixth tergites moderately convex. First tergite subparallel-sided. Length of first tergite 1.5–1.6 × its maximum (subapical) width; its maximum width 1.2–1.3 × minimum (basal) width. Suture between second and third tergites almost without sublateral bends. Second tergite without sublateral furrows, its median length 1.2 × basal width, 1.2 × median length of third tergite. First, second and most part of third tergites entirely coarsely and densely reticulate. Third to fifth tergites with distinct wide transverse crenulated sulcus basally. Fourth to sixth tergite mainly dense and small granulate-punctate, third to fifth tergites smooth on narrow apical transverse stripes. Frons weakly curvedly striate; mesoscutum mostly rugose except median lobe anteriorly. Vertex mainly glabrous with a few scattered setae; mesoscutum mostly covered by short and rather dense setae. Body almost entirely orange yellow, except for apex of metasoma dark brown; antenna mostly dark brown but yellowish orange basally; wings hyaline, veins and pterostigma dark brown.

Distribution. Ecuador, Peru, Brazil.

Etymology. Named after country where the holotype was collected.

Comparative diagnosis. This new species belongs to the morphological group with widely setose mesoscutum. Pedinotus peruanus sp. nov. is similar to P. brasiliensis Szépligeti ; however, it differs from the latter species by having a distinct medio-longitudinal furrow anteriorly on median lobe of mesoscutum (absent in P. brasiliensis ), distinctly sinuate vein (RS+M)a on fore wing (weakly curved in P. brasiliensis ), mesosoma not depressed (more or less distinctly depressed in P. brasiliensis ), and wings distinctly infuscate (wings faintly infuscate in P. brasiliensis ).
