Description. Female. Body length 5.8 mm; fore wing length 3.9 mm.

Head width (dorsal view) 1.6 × its median length, 1.3 × maximum width of mesoscutum. Head behind eyes (dorsal view) roundly narrowed. Eye 2.3 × longer than temple (dorsal view). Ocelli medium-sized, arranged in almost equilateral triangle. POL 1.1 × Od, 0.5 × OOL. Frons weakly concave, with fine but distinct and long median longitudinal carina. Eye glabrous, 1.2 × higher than broad. Face width 0.6 × height of eye and 1.1 × height of face and clypeus combined. Malar space about 0.3 × height of eye, 1.1 × basal width of mandible. Hypoclypeal depression width 1.3 × the shortest distance between depression and eye and 0.5 × width of face.

Antenna slender, almost filiform, with more than 39 antennomeres (apical segments missing). Scape 1.4 × longer than its maximum width. First flagellomere 7.5 × longer than its apical width, 1.3 × longer than second flagellomere. Submedian flagellomeres about 5.0 × longer than their maximum width.

Mesosoma 2.1 × longer than its maximum height. Pronotum distinctly convex dorsally (lateral view) and with fine submedian pronotal carina (dorsal view). Median lobe of mesoscutum distinctly protruding forwards (lateral view) and anteriorly weakly convex and without median longitudinal furrow. Notauli complete, deep anteriorly and shallow posteriorly, crenulated. Median length of mesoscutum about equal to its maximum width. Prescutellar depression (scutellar sulcus) rather deep, finely crenulated, with three distinct carinae, 0.4 × as long as scutellum medially. Precoxal sulcus (sternaulus) deep, smooth, running along almost entire length of lower part of mesopleuron.

Wings. Fore wing 3.5 × longer than maximum width. Vein r (first radial abscissa) arising before middle of pterostigma. Vein 3RSa (second radial abscissa) 2.7 × longer than vein r (first radial abscissa), 0.45 × as long as the straight vein 3RSb (third radial abscissa), 1.3 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell 1.7 × longer than maximum width, 0.7 × as long as 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, 1.3 × longer than distance between veins 1M (basal) and nervulus (1cu-a). First subdiscal cell 4.5 × longer than maximum width. Hind wing vein M+CU (first submedial abscissa) 0.3 × as long as vein 1-M (second submedial abscissa). Vein m-cu (recurrent) almost straight and distinctly antefurcal.

Legs. Hind femur 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 hind basitarsus, 1.4 × longer than fifth segment (without pretarsus).

Metasoma 1.1 × longer than mesosoma and head combined. First tergite without basolateral lobes and spiracular tubercles, distinctly and linearly widened from subbase to apex. Length of first tergite 0.9 × its maximum (subapical) width; maximum width 1.4 × its minimum (basal) width. Second tergite with short, rather shallow and wide, almost parallel sublateral furrows; median length of second tergite 0.5 × its basal width, 0.75 × median length of third tergite. Suture between second and third tergites entirely shallow and rather wide, distinctly sinuate. Third tergite with distinct wide transverse crenulated sulcus in basal third. Ovipositor sheath about as long as metasoma, 1.5 × longer than mesosoma, 0.7 × as long as fore wing.

Sculpture and pubescence. Vertex smooth; frons partly smooth, with transverse curved striation; face areolaterugose. Mesoscutum smooth, rugulose in medioposterior quadrangular area. Mesopleuron mainly almost smooth. Metapleuron smooth with very fine granulation, rugose posteriorly. Propodeum with rugose basolateral areas distinctly delineated by carinae; areola undefined, areolate-rugose. Hind coxa and femur mainly smooth. First and second metasomal tergites coarsely and sparsely rugose. Third tergites rugose in basal 0.2 (medially)–0.8 (laterally) and smooth apically. Fourth and fifth tergites areolate-rugose basally and smooth apically; sixth tergite punctate basally, smooth apically. Remaining tergites smooth. Vertex mainly glabrous. Mesoscutum mostly glabrous. Dorsal side of hind tibia with long, rather sparse and semi-erect pale setae, length of the longest setae 0.9 × maximum width of tibia.

Colour. Head mainly yellow, frons till ocellar triangle black. Palpi whitish. Antenna mainly black, three basal segments with yellowish tint. Mesosoma mainly yellow, metapleuron light yellow; propodeum anteriorly sometimes light brown. Tegula pale yellow. Metasoma light brown to black, white laterally. Legs mainly light yellow, all hind tarsi brown; fore and mid coxae, trochanter and trochantellus whitish; mid tibia brown apically; hind coxa brown antero-apically, hind trochanter and trochantellus light brown anteriorly, hind femur light brown antero-basally and brown apically, hind tibia white basally. Ovipositor sheath black. Wings faintly and evenly infuscate. Pterostigma brown.

Male. Unknown.

Distribution. Brazil.

Etymology. Named after the character of Greek mythology, Daedalus, father of Icarus.

Comparative diagnosis. This new species belongs to the morphological group with glabrous mesoscutum.

Pedinotus daedalus sp. nov. is similar to P. cerdai sp. nov., but differs from it by having a deeps precoxal sulcus extending over most of the mesopleuron length (very shallow and short in P. cerdai ), head and temple short (long in P. cerdai ), suture between second and third tergites distinctly sinuate (weakly sinuate in P. cerdai ), and the first tergite rugose (striate with reticulation in P. cerdai ).
