Sculpture and pubescence. Vertex transverse curved-striate, with rugulosity in anterior half (with ocellar triangle) or sometimes only quarter, rarely almost without striae and rugae, rugulose-punctate or punctate submedially or (rarely) mainly, smooth or almost smooth in posterior third; frons entirely densely coarsely curvedstriate-rugose; face distinctly densely transversely curved-striate, partly with fine rugosity between striae. Mesoscutum entirely densely and distinctly punctate, with wide subrectangular coarsely rugose-areolate medioposterior area, lateral lobes with rather long transverse striae along median area. Scutellum densely and distinctly punctate with fine rugulosity. Mesopleuron mainly striate-rugulose with dense punctation in lower third, almost smooth upper of precoxal sulcus (sternaulus) on narrow stripe. Metapleuron densely punctate, with dense rugulosity in upper half. Propodeum entirely densely punctate-areolate, without delineated areas, baso-median carina in basal half rather distinct or fine. Hind coxa smooth laterally, densely punctate with curved striation dorsally. Hind femur mainly almost smooth, coriaceous dorsally. First and second metasomal tergites coarsely and densely reticulate-areolate, reticulation small on sides of second tergite. Third to six tergites almost entirely very densely and small reticulate-areolate to punctate, sculpture becoming finer toward apex of all tergites. Vertex mainly covered by dense and short golden setae, glabrous on narrow posterior area. Mesoscutum entirely with very dense short yellow setae. Dorsal side of hind tibia with short, sparse and semi-erect pale setae, their length about 0.4 × maximum width of tibia.

Colour. Head yellow to pale yellow, most part of frons and almost all vertex black. Palpi pale yellow. Antenna mainly black, scape and pedicel yellow or brownish yellow with dark brown areas. Mesosoma pale yellow, sometimes faintly darker, mesoscutum and scutellum light reddish brown, propodeum medially and posteriorly black. Metasoma yellow to pale yellow, with large and different shapes spots on all tergites. Tegula yellow. Fore and mid legs mainly pale yellow with a few short or long and narrow dark spots on femora and tibiae. Hind leg mainly dark brown to black, hind coxa in basal half and apically or in ventral 0.2, large submedian spots on femur and baso-dorsal area of hind tibia yellow to pale yellow. Ovipositor sheath entirely black. Wings entirely almost hyaline. Pterostigma entirely black.

Male. Unknown.

Distribution. French Guiana, Colombia.

Etymology. Named after " Guyane francaise" ( French Guiana), the country where the holotype was collected.

Comparative diagnosis. This new species belongs to the morphological group with mainly glabrous mesoscutum. Pedinotus guyanensis sp. nov. is similar to P. niger Marsh , but differs from it in having mesosoma mainly yellow with reddish mesoscutum (black in P. niger ), malar space 0.20–0.25 × height of eye (0.33 × in P. niger ), first flagellomere longer than second one (distinctly shorter in P. niger ), fore and mid legs mainly yellow (mainly black except coxae in P. niger ), tergites behind third one very densely and distinctly punctate apically (smooth in P. niger ), and ovipositor sheath longer than metasoma (not longer in P. niger ).

Remarks. The two examined specimens that were not included as types are morphologically very similar to the types of P. guyanensis , but differ from them by having the first metasomal tergite short with its length about 0.9 × its maximum subapical width. We prefer maintain the former specimens within this new species pendant to further morphological and molecular evidence.
