Description. Female. Body length 9.8 mm; fore wing length 8.5 mm.

Head width (dorsal view) 1.4 × its median length, 1.3 × maximum width of mesoscutum. Head behind eyes (dorsal view) roundly narrowed. Eye 1.9 × longer than temple (dorsal view). Ocelli medium-sized, arranged in almost equilateral triangle. POL equal to Od, 0.3 × OOL. Frons concave, with fine but distinct and long median longitudinal carina. Eye glabrous, weakly higher than broad. Face width 0.9 × height of eye and 1.1 × height of face and clypeus combined. Malar space 0.3 × height of eye, equal to basal width of mandible. Hypoclypeal depression width 1.1 × the shortest distance between depression and eye and 0.5 × width of face.

Antenna slender, almost filiform, with 51 antennomeres. Scape 1.6 × longer than its maximum width. First flagellomere 5.0 × longer than its apical width, 1.1 × longer than second flagellomere. Submedian flagellomeres about 3.5 × longer than their maximum width.

Mesosoma 1.8 × 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, shallow and entirely smooth. Median length of mesoscutum 1.1 × its maximum width (dorsal view). Prescutellar depression (scutellar sulcus) rather deep, finely crenulated, with five distinct carinae, 0.3 × as long as scutellum medially. Precoxal sulcus (sternaulus) shallow, but distinct, smooth, running along entire length of lower part of mesopleuron.

Wings. Fore wing about 4.0 × longer than maximum width. Vein r (first radial abscissa) arising 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 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) interstitial, subparallel to vein 1M (basal). Vein 1cu- a (nervulus) postfurcal, about 0.7 × longer than distance between veins 1M (basal) and 1cu-a (nervulus). Hind wing vein M+CU (first submedial abscissa) 0.5 × as long as vein 1-M (second submedial abscissa). Vein m-cu (recurrent) almost straight and interstitial.

Legs. Hind femur 4.0 × 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, 2.1 × longer than fifth segment (without pretarsus).

Metasoma as long as mesosoma and head combined. First tergite with basolateral lobes and spiracular tubercles, almost linearly widening from subbase to apex. Length of first tergite equal to its maximum (subapical) width; maximum width 1.3 × its minimum (basal) width. Second tergite with wide, rather shallow and distinctly convergent posteriorly sublateral furrows; median length of second tergite 0.65 × its basal width, 1.2 × median length of third tergite. Suture between second and third tergites entirely shallow, distinctly sinuate, with weak sublateral bends. Third tergite with distinct, wide, weakly crenulated and sinuate transverse furrow at basolateral third. Ovipositor sheath 1.2 × longer than metasoma, 2.2 × longer than mesosoma, 0.9 × as long as fore wing.

Sculpture and pubescence. Vertex smooth; frons partly smooth, with transverse curved striation; face rugose, costate near eyes. Mesoscutum smooth, with very small rugulose medioposterior triangle area. Mesopleuron and metapleuron mainly smooth. Propodeal areas partly delineated by distinct carinae, basolateral areas smooth in anterior half and rugulose in posterior half, with rugosity along carinae; areola undefined and rugulose; basomedian carina about half of propodeum length. Hind coxa and femur mainly smooth. First metasomal tergite entirely rugose; second tergite with semi-circular costate median area; third tergite completely smooth. Remaining tergites entirely smooth. Vertex glabrous on wide median area, with sparse and short setae along eyes. Mesoscutum mostly glabrous. Dorsal side of hind tibia with long, rather sparse and semi-erect pale setae, the longest setae about equal to maximum width of tibia.

Colour. Head black, clypeus light yellow, sides of malar area on border with mandible brownish. Palpi from brownish basally and whitish apically. Antenna entirely black. Mesosoma mainly orange, metapleuron and lower part of pronotum black. Tegula brownish orange. Metasoma orange, light yellow laterally, first tergite and semicircular area of second tergite yellow, last two tergites brown, light brown laterally. Legs mainly yellow to brownish yellow; fore coxa dark brown, mid and hind coxae black; mid tibia whitish basally. Hind leg mainly dark brown. Ovipositor sheath entirely black. Wings faintly and evenly infuscate. Pterostigma brown.

Male. Unknown.

Distribution. Brazil.

Etymology. Named in honour of Haliti-Paresi people, inhabitants of the region were the holotype of this new species was collected.

Comparative diagnosis. This new species belongs to the morphological group with glabrous mesoscutum. Pedinotus haliti sp. nov. resembles P. elongatus sp. nov. and P. avispas sp. nov. This new species differs from P. elongatus in having the notauli anteriorly smooth (crenulated in P. elongatus ), third metasomal tergite completely smooth and polished except for the crenulated transverse sulcus (very dense and small reticulate-areolate in P. elongatus ), and propleuron, parts of pronotum and metapleuron black (entirely orange in P. elongatus ). It is also similar to P. nitidus sp. nov. but differs from it in having the large size of the body (small size in P. nitidus ), mesosoma short and high, 1.8 × longer that its width (long and low, 2.2 time longer that its width in P. nitidus ), nervulus (1cu-a) distinctly postfurcal (weakly postfurcal in P. nitidus ), hind tarsus about as long as hind tibia (distinctly longer in P. nitidus ), second segment of hind tarsus 2.1 × longer than fifth segment (1.4 × in P. nitidus ), length of first metasomal tergite equal to its maximum width (1.2 × longer in P. nitidus ), median length of second metasomal tergite 1.2 × median length of third tergite (0.8 × in P. nitidus ), first metasomal tergite entirely rugose first tergite mainly smooth in P. nitidus ); second tergite with semi-circular costate median area (second tergite striate medially in P. nitidus ), palpi pale apically (entirely brown in P. nitidus ), metasoma orange (mainly black in P. nitidus ), and legs mainly yellow to brownish yellow (mainly black excdpt to fore leg dark reddish brown to reddish brown in P. nitidus ). Morphological differences between P. haliti and P. avispas are shown in the description of the later species.
