Description. Female. Body length 7.8 mm; fore wing length 5.1 mm.

Head width (dorsal view) 1.7 × its median length, 1.2 × maximum width of mesoscutum. Head behind eyes (dorsal view) roundly narrowed. Eye 1.6 × longer than temple (dorsal view). Ocelli medium-sized, arranged in almost equilateral triangle. POL 0.7 × Od, 0.3 × OOL. Frons concave, with fine but distinct and long median longitudinal carina. Eye glabrous, 1.3 × higher than broad. Face width 0.9 × height of eye and equal to height of face and clypeus combined. Malar space 0.3 × height of eye, as long as almost equal tobasal width of mandible. Hypoclypeal depression width 0.6 × the shortest distance between depression and eye and 0.5 × width of face.

Antenna slender, almost filiform, with more than 41 antennomeres (apical antennomeres missing). Scape 1.35 × longer than its maximum width. First flagellomere 5.2 × longer than its apical width, 1.1 × longer than second flagellomere. Submedian flagellomeres about 4.0 × longer than their maximum width.

Mesosoma 2.0 × 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 and anteriorly weakly convex, without median longitudinal furrow. Notauli complete, weakly scrobiculate anteriorly. Median length of mesoscutum 1.1 × its maximum width. Prescutellar depression (scutellar sulcus) rather deep, finely crenulated, with three distinct carinae, about 0.5 × as long as scutellum medially. Precoxal sulcus (sternaulus) absent.

Wings. Fore wing 3.5 × longer than maximum width. Vein r (first radial abscissa) arising almost from middle of pterostigma. Vein 3RSa (second radial abscissa) 2.0 × longer than vein r (first radial abscissa), 0.3 × as long as the straight vein 3RSb (third radial abscissa), 1.3 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell 2.0 × 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 postfurcal, subparallel to vein 1M (basal). Vein 1cu-a (nervulus) postfurcal, about 0.1 × as long as distance between veins 1M (basal) and nervulus (1cu-a). Hind wing vein M+CU (first submedial abscissa) 0.3 × as long as vein 1-M (second submedial abscissa). Vein mcu (recurrent) straight and distinctly antefurcal.

Legs. Hind femur 3.7 × longer than maximum width. Hind tarsus about 1.2 × longer than 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, 2.0 × longer than fifth segment (without pretarsus).

Metasoma 1.1 × longer than mesosoma and head combined. First tergite with basolateral lobes and without spiracular tubercles, distinctly and linearly widened from subbase to apex. Length of first tergite equal to its maximum (subapical) width; maximum width 1.4 × its minimum (basal) width. Second tergite with wide, rather shallow and short, almost parallel sublateral furrows; median length of second tergite 0.45 × its basal width, 0.6 × median length of third tergite. Suture between second and third tergites entirely deep and rather wide, distinctly sinuate. Third tergite with distinct wide transverse crenulated sulcus in basal third. Ovipositor sheath 0.8 × as long as metasoma, 1.3 × longer than mesosoma, 0.6 × as long as fore wing.

Sculpture and pubescence. Vertex smooth; frons partly smooth, with transverse curved striation; face costate, with smooth elevation on central area. Mesoscutum smooth, rugulose in medioposterior triangle area. Mesopleuron mainly smooth. Metapleuron smooth, rugose posteriorly. Propodeal areas distinctly delineated by carinae, basolateral areas rugulose and with rugosity along carinae, areola not distinctly delineated and rugose; basomedian carina longer than anterior fork of areola. Hind coxa and femur mainly smooth. First metasomal tergite ruguloselacunose, second tergite with median rugose semicircular area. Third tergite distinctly and densely ruguloselacunose in basal 0.3 (medially)–0.6 (laterally) and smooth apically. Fourth to sixth tergites very densely areolaterugose in basal halves, smooth apically. Remaining tergites smooth. Vertex glabrous on wide area. Mesoscutum mostly glabrous. Dorsal side of hind tibia with long, rather sparse and semi-erect pale setae, length of the longest setae 1.5 × maximum width of tibia.

Colour. Head mainly black, but yellow in ventral half. Palpi yellow. Antenna black. Mesosoma mainly orange, metapleuron and propodeum mainly light yellow, propodeum with basal and central areas black. Tegula light yellow. Metasoma black dorsally, light yellow laterally. Legs mainly yellow, all tarsi brown except mid tarsus dark yellow; hind coxa black apico-dorsally; trochanter and trochantellus dark brown, hind femur yellow, dark brown apically and basally; hind tibia dark brown, whitish basally. Ovipositor sheath entirely black. Wings faintly and evenly infuscate. Pterostigma mostly brown with yellow basal quarter.

Male. Unknown.

Distribution. Brazil.

Etymology. This new species is named in honour of the Hungarian entomologist Dr Gyözö Szépligeti, one of the most important experts on the Neotropical Braconidae fauna.

Comparative diagnosis. Pedinotus szepligetii sp. nov. belongs to the morphological group with glabrous mesoscutum. This new species is very similar to P. dispar sp. nov., however, it differs from the latter species by having a body mostly yellow or light yellow with less extensive black marking (more extensive markings in P. dispar on a mostly brownish yellow ground colour); hind coxa yellow basally and black apically (entirely black in P. dispar ); pterostigma brown with yellow basal quarter (entirely dark brown in P. dispar ); the first tergite entirely rugose with weak sculpture along lateral borders (its lateral areas distinctly reticulate-rugose and median part of tergite rugose-striate in P. dispar ); the second tergite is entirely rugose in P. szepligetii (striate with reticulation between striae in P. dispar ); width of face 0.9 × height of eye (0.70–0.75 in P. dispar ); the second submarginal cell widened apically and 2.0 × longer than wide (not widened and 2.3–2.6 × longer than wide in P. dispar ); second segments of hind tarsus about 2.0 × longer than fifth segment (1.3–1.5 × in P. dispar ).
