Head width (dorsal view) 1.4 × its median length, 1.4 × maximum width of mesoscutum. Head behind eyes (dorsal view) roundly narrowed. Eye 1.5 × longer than temple (dorsal view). Ocelli medium-sized, arranged in triangle with base 1.3 × its sides, arranged in almost equilateral triangle. POL 0.8 × Od, 0.5 × OOL. Frons weakly concave, without median longitudinal carina. Eye glabrous, 1.3 × higher than broad. Face width 08 × height of eye and 0.8 × height of face and clypeus combined. Malar space 0.4 × height of eye, about equal to basal width of mandible. Hypoclypeal depression width almost equal to the shortest distance between depression and eye and 0.5 × width of face.

Antenna slender, almost filiform, with more than 20 antennomeres (apical flagellomeres missing). Scape 1.3 × as long as its maximum width. First flagellomere 5.5 × longer than its apical width, 0.8 × longer than second flagellomere. Submedian flagellomeres 3.5 × longer than their maximum width.

Mesosoma 2.2 × longer than its maximum height. Pronotum distinctly convex dorsally (lateral view) and without submedian pronotal carina (dorsal view). Median lobe of mesoscutum distinctly protruding forwards and anteriorly weakly convex, without median longitudinal furrow. Notauli deep anteriorly and shallow posteriorly, crenulated. Median length of mesoscutum 1.1 × its maximum width. Prescutellar depression (scutellar sulcus) rather deep, finely crenulated, with four distinct carinae, 0.4 × as long as scutellum medially. Precoxal sulcus (sternaulus) present, running along most of length of lower part of mesopleuron.

Wings. Fore wing 4.7 × longer than maximum width. Vein r (first radial abscissa) arising from middle of pterostigma. Vein 3RSa (second radial abscissa) 1.5 × longer than vein r (first radial abscissa), 0.4 × as long as the straight vein 3RSb (third radial abscissa), 1.7 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell 3.15 × longer than maximum width, 0.8 × as long as first subdiscal (brachial) cell. Vein (RS+M)a (first medial abscissa) weakly sinuate. Vein 1m-cu (recurrent) almost interstitial, subparallel to vein 1M (basal). Vein 1cu-a (nervulus) postfurcal, 0.1 × as long as distance between veins 1M (basal) and 1cu-a (nervulus). Hind wing vein M+CU (first submedial abscissa) 0.35 × as long as vein 1-M (second submedial abscissa). Vein mcu (recurrent) almost straight and distinctly antefurcal.

Legs. Hind femur 3.2 × longer than maximum width. Hind tarsus about as long as hind tibia. Basitarsus of hind tarsus 0.8 × as long as second-fifth segments of hind tarsus combined. Second segment of hind tarsus 0.5 × as long as basitarsus, 1.7 × longer than fifth segment (without pretarsus).

Metasoma 1.2 × longer than mesosoma and head combined. First tergite without basolateral lobes and spiracular tubercles. Length of first tergite 1.2 × its maximum (subapical) width; maximum width 1.3–1.4 × its minimum (basal) width. Second tergite with distinct long and convergent sublateral furrows; median length of second tergite 0.6 × its basal width, 0.8 × median length of third tergite. Suture between second and third tergites entirely deep and rather wide, distinctly sinuate, with not strong sublateral bends. Third tergite with distinct wide transverse crenulated sulcus in basal 0.4. Ovipositor sheath 0.9 × longer than metasoma, 1.8 × longer than mesosoma, 0.65 × longer than fore wing.

Sculpture and pubescence. Vertex smooth; frons partly smooth, with weak transverse striation; face coarse costate-rugose, with an elevate rugose area centrally. Mesoscutum mainly smooth, rugose-reticulate in medioposterior quadrangular area. Mesopleuron mainly smooth. Metapleuron smooth. Propodeal areas distinctly delineated by carinae, areolate-rugose, areola not delineated by carinae, its area areolate-rugose. Hind coxa and femur mainly smooth. First metasomal tergite rugulose-lacunose; second tergite with semicircular area finely areolate-rugulose. Third tergite distinctly and densely areolate-rugose to areolate in basal 0.7 (medially)–0.6 (laterally) and smooth apically. Fourth-sixth tergites very densely areolate-rugose in basal halves, smooth on remaining parts. Vertex glabrous on wide area, with sparse short setae medio-posteriorly. Mesoscutum with median lobe with setae, lateral lobes mainly glabrous. Dorsal side of hind tibia with long, rather sparse and semi-erect pale setae, length of longest setae equal to maximum width of tibia.

Colour. Head mainly yellow, with a black stripe from upper face to occipital carina. Palpi light yellow. Antenna black. Mesosoma black except propleuron and pronotum ventrally yellow; mesoscutum with quadrangular area yellow medio-posteriorly. Tegula yellow. Metasoma black to brown, second to seventh tergites light yellow laterally. Fore and mid legs mainly yellow, tarsi dark yellow. Mid coxa dark brown. Hind leg dark brown, hind coxa black, trochanter and trochantellus dark brown, femur yellow, basal two thirds of hind femur light to dark brown; hind tibia and tarsi dark brown. Ovipositor sheath black. Wings distinctly infuscate. Pterostigma dark brown.

Male. Unknown.

Distribution. Brazil.

Comparative diagnosis. Pedinotus tundisii Felix et Penteado-Dias has a pronotum and mesopleuron distinctly covered by white setae and the mesoscutum is mostly glabrous and devoid of setae at lateral lobes. This species is similar to P. daedalus sp. nov., from which it differs in the black frons and vertex and mostly dark brown mesosoma (head and mesosoma mostly yellow in P. daedalus), mid and hind coxae black (mostly yellow, but not for a ventral dark brown spot in P. daedalus), and mesopleuron above precoxal sulcus covered be a dense long white setae (only sparsely partly setose in P. daedalus).
