Mesosoma 2.0–2.3 × longer than its maximum height. Pronotum distinctly convex dorsally (lateral view), with fine submedian pronotal carina (dorsal view). Median lobe of mesoscutum distinctly protruding forwards, anteriorly weakly convex, with distinct narrow median longitudinal furrow anteriorly. Notauli complete, deep and crenulated anteriorly, shallow posteriorly. Median length of mesoscutum about 1.2 × its maximum width. Prescutellar depression (scutellar sulcus) rather deep, finely crenulated, with five distinct carinae, 0.4 × as long as scutellum medially. Precoxal sulcus (sternaulus) deep and scrobiculate anteriorly, running along anterior 0.6–0.7 × of lower part of mesopleuron.

Wings. Fore wing 3.8–4.1 × longer than maximum width. Vein r (first radial abscissa) arising from middle of pterostigma. Vein 3RSa (second radial abscissa) 2.0–2.3 × longer than vein r (first radial abscissa), 0.4 × as long as the straight vein 3RSb (third radial abscissa), 1.5–1.6 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell about 2.0 × longer than maximum width, 0.8–0.9 × as long as first subdiscal (brachial) cell. Vein (RS+M)a (first medial abscissa) weakly sinuate. Vein 1m-cu (recurrent) weakly antefurcal or interstitial, subparallel to vein 1M (basal). Vein 1cu-a (nervulus) postfurcal, 2.1–2.5 × longer than distance between veins 1M (basal) and nervulus (1cu-a). Hind wing vein M+CU (first submedial abscissa) 0.2–0.3 × as long as vein 1-M (second submedial abscissa). Vein m-cu (recurrent) almost straight and distinctly antefurcal.

Legs. Hind femur 3.3–3.7 × longer than maximum width. Hind tarsus about as long as hind tibia. Basitarsus of hind tarsus 0.7–0.9 × as long as second-fifth segments of hind tarsus combined. Second segment of hind tarsus 0.4– 0.5 × as long as basitarsus, 1.4–1.5 × longer than fifth segment (without pretarsus).

Metasoma 1.1–1.2 × 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 0.8–0.9 × its maximum (subapical) width; maximum width 1.5–1.7 × its minimum (basal) width. Second tergite with short sublateral furrows; median length of second tergite 0.4 × its basal width, 0.7–0.9 × 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 at basal third. Ovipositor sheath 0.6–0.7 × as long as metasoma, 1.3–1.4 × longer than mesosoma, 0.6 × as long as fore wing.

Sculpture and pubescence. Vertex smooth; frons with transverse curved striation; face coarsely areolaterugose. Mesoscutum mainly smooth and punctate, rugose in medioposterior subquadrangular area. Mesopleuron mainly almost smooth. Metapleuron smooth, rugose posteriorly. Propodeum with areas indistinctly delineated by carinae, entirely rugose, without areola. Hind coxa and femur mainly smooth. First metasomal tergite and semicircular area of second tergite coarsely rugose, lateral areas of second metasomal tergite rugulose-lacunose. Third tergite distinctly and densely punctate in basal 0.3 (medially)–0.6 (laterally) and smooth apically: fourth and fifth tergites very densely and finely areolate-rugose in basal halves, smooth apically; sixth tergite punctatealveolate basally, smooth apically. Remaining tergites smooth. Vertex glabrous on wide area, with sparse short setae medioposteriorly. Mesoscutum with short, rather dense and semi-erect pale setae. Dorsal side of hind tibia with long, rather sparse and semi-erect pale setae, their length 0.8–0.9 × maximum width of tibia.

Colour. Head mainly yellow, frons and vertex medially brown to dark brown, temple whitish yellow, face dark brown above clypeus. Palpi whitish yellow. Antenna black. Mesosoma mainly yellow, propodeum mostly black; mesoscutum sometimes with dark brown median and lateral lobes. Tegula yellow or brown. Metasoma black, whitish yellow or yellow laterally, fifth tergite light brown apically, last tergite white or yellow, brown apically. Legs whitish yellow or yellow, all tarsi pale brown but fifth tarsal segment brown; fore and mid coxae, trochanter and trochantellus whitish yellow to yellow, fore and mid femora with spots light brown anteriorly, mid femur white posteriorly; fore tibia light yellow, darker apically, mid tibia brown, white basally; hind coxa dark brown, whitish basally and apically, light yellow dorso-posteriorly, hind trochanter and trochantellus brown, paler at borders; femur dark brown, except half of its apical part whitish or yellow; tibia light brown, white basally. Ovipositor sheath black. Wings faintly and evenly infuscate. Pterostigma brown, faintly pale basally and apically. The specimen from Southern Brazil is generally darker than the specimen from Northern Brazil.

Male. Unknown.

Distribution. Brazil.

Etymology. The species is named in honour of Candido Mariano da Silva Rondon (Marechal Rondon), one of the most important persons in Brazilian history, considered a national hero for his work with native people and after whom the state Rondonia was named.

Comparative diagnosis. This new species belongs to the morphological group with widely setose mesoscutum. Pedinotus rondoni sp. nov. is morphologically similar to P. brasiliensis Szépligeti ; however, it differs from the latter species by having a mainly yellow mesosoma (mainly dark brown in P. brasiliensis ), median lobe of mesoscutum with distinct longitudinal sulcus (without distinct longitudinal sulcus in P. brasiliensis ), and the first flagellomere shorter than second one (almost the same length in P. brasiliensis ).
