Length of first tergite 0.9–1.1 (rarely 1.2) × its maximum (subapical) width; maximum width 1.3–1.5 × its minimum (basal) width. Median length of second tergite 0.7–0.9 × its basal width, 1.3–1.5 × length of third tergite; maximum median length of second tergite 1.5– 1.7 × its minimum sublateral length (at level of breaks). Ovipositor sheath 1.2–1.3 × longer than metasoma, 2.0–2.5 × longer than mesosoma, 1.0–1.2 × as long as fore wing.

Sculpture and pubescence. Vertex mainly smooth, sometimes with fine striation anterolaterally; frons widely and distinctly rugose with oblique or curved striation, sometimes finely granulate-coriaceous or smooth laterally or submedially; face coarsely rugose-areolate with striation, with sublateral curved and convergent below crenulated furrows, rarely finely granulate medially, only curved striae below. Mesoscutum densely and finely or sometimes very finely punctate, rarely almost smooth, with wide and coarse rugose-reticulate area in medioposterior 0.6–0.7. Mesopleuron in lower half mainly finely and usually numerously punctate. Metapleuron entirely finely reticulateareolate or reticulate-coriaceous. Propodeum almost entirely reticulate-areolate; basolateral areas wide and delineated by carinae; areola rather wide and short or sometimes not delineated anteriorly by carinae; basomedian carina usually almost half of propodeum length. Hind coxa finely or very finely reticulate-rugulose with reticulation in dorsal half, finely coriaceous to smooth on lateral and in ventral half or sometimes entirely. Hind femur mainly smooth. First metasomal tergite entirely densely and coarsely small rugose-areolate. Second tergite entirely and densely small reticulate-areolate. Third-fifth tergites very densely and small areolate-punctate in basal 0.5–0.3 and smooth in apical halves, third tergite with additional distinct striations; sixth tergite very finely punctate basally, mainly smooth. Vertex mainly glabrous, with sparse, long and semi-erect pale setae laterally and posteriorly. Mesoscutum mainly with very dense, short and semi-erect white setae, glabrous usually in narrow areas on lateral lobes and always anteriorly on median lobe. Hind tibia dorsally with rather sparse, semi-erect and medium length white setae, length of these setae 0.5–0.8 × maximum width of hind tibia.

Colour. Head mainly almost black, sometimes reddish in ring around eyes and in median spot of face, often temple in lower half or third brownish yellow, malar space and clypeus at least below light reddish brown or brownish yellow. Palpi yellow. Antenna black, sometimes reddish basally. Mesosoma brownish yellow to light reddish brown or orange, sometimes dark brown to black on dorso-posterior corners of pronotal sides, lateral lobes of mesoscutum, scutellum, metanotum, and apical half of mesopleuron; rarely mesosoma almost entirely light reddish brown. Metasoma dark reddish brown to black, laterally and ventrally mainly pale yellow, yellow to brownish yellow. Legs reddish brown to dark reddish brown, fore coxa, fore and mid trochanters and trochantelli and sometimes most part of mid tarsus yellow to brownish yellow; sometimes mid and always hind coxae almost black or black, all femora sometimes with pale spot on dorso-posterior thirds; all tibiae subbasally yellow at least on small area. Ovipositor sheaths entirely black. Wings faintly, but distinctly and evenly infuscate. Pterostigma entirely dark brown.

Male. Unknown.

Distribution. Costa Rica, Panama, Colombia, Venezuela, French Guiana.

Comparative diagnosis. This species belongs to the morphological group with densely setose mesoscutum. Pedinotus columbianus Enderlein is morphologically similar to P. brasiliensis Szépligeti. Differences between these species are shown in the key.
