Median lobe of mesoscutum distinctly protruding forwards and not high elevated above pronotum (lateral view), anteriorly weakly convex and with distinct medioanterior depression, but without median longitudinal furrow. Notauli complete, deep and crenulated. Median length of mesoscutum 1.2 × its maximum width. Prescutellar depression (scutellar sulcus) shallow, rugulose, with four-five distinct carinae, about 0.3 × as long as scutellum medially.

Wings. Fore wing 4.0–4.3 × longer than maximum width. Vein r (first radial abscissa) arising almost from middle of pterostigma. Vein 3RSa (second radial abscissa) 2.0–2.7 × longer than vein r (first radial abscissa), 0.4 × as long as the straight vein 3RSb (third radial abscissa), 1.4–1.7 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell 2.8–2.9 × longer than maximum width, 0.9–1.0 × as long as first subdiscal (brachial) cell. Vein (RS+M)a (first medial abscissa) distinctly sinuate. Vein 1m-cu (recurrent) weakly antefurcal, subparallel to vein 1M (basal). Vein 1cu-a (nervulus) postfurcal, 0.4-–0.5 × as long as distance between veins 1M (basal) and nervulus (1cu-a). Hind wing vein M+CU (first submedial abscissa) 0.25–0.30 × as long as vein 1-M (second submedial abscissa). Vein m-cu (recurrent) almost straight, antefurcal to almost interstitial.

Legs. Hind femur 3.8–4.2 × longer than maximum width. Hind tarsus 1.10–1.15 × longer than hind tibia. Basitarsus of hind tarsus 0.7–0.8 × as long as second-fifth segments of hind tarsus combined. Second segment of hind tarsus about 0.5 × as long as basitarsus, 1.5–1.8 × longer than fifth segment (without pretarsus).

Metasoma 1.1–1.3 × longer than mesosoma and head combined. First tergite without basolateral lobes and spiracular tubercles, weakly and linearly widened from subbase to apex. Length of first tergite 1.0–1.2 (rarely almost 1.3) × its maximum (subapical) width; maximum width 1.4–1.7 × its minimum (basal) width. First and second tergites perhaps mobile connected. Second tergite with wide, shallow, nearly parallel sublateral furrows; median length of second tergite 0.5–0.6 × its basal width, about 0.9 × median length of third tergite. Suture between second and third tergites entirely deep and rather wide, distinctly sinuate, with strong sublateral breaks; meximum median length of second tergite about 2.5 × its minimum sublateral length (on level of break). Third tergite with distinct wide transverse crenulated sulcus in basal third. Ovipositor sheath 1.2–1.4 × longer than metasoma, 1.7– 2.0 × longer than mesosoma, 0.8–1.0 × as long as fore wing.

Sculpture and pubescence. Vertex smooth in posterior 0.4–0.6 and laterally, with fine or distinct transverse striation medially in anterior 0.4–0.6 and near ocelli; frons densely transversely striate with fine reticulation; face rugose-areolate with striation. Mesoscutum mostly and densely punctate on median and lateral lobes, rugose on long medioposterior rectangular area. Mesopleuron mainly more or less densely punctate, smooth ventrally. Metapleuron finely or very finely reticulate-striate, partly smooth, rugose-reticulate below and posteriorly. Propodeal basolateral areas more or less distinctly delineated by carinae, areola not delineated, propodeum entirely and densely areolate-rugose. Hind coxa and femur smooth or almost smooth. First entirely and second medially metasomal tergites coarsely areolate-rugose, second tergite striate laterally. Third tergite distinctly and densely small foveolate-areolate in basal 0.5–0.6 and smooth apically. Fourth to sixth tergites very densely and small punctate in basal 0.3–0.5, smooth on remaining parts. Vertex setose, varying from scattered short setae to densely setose, almost glabrous posteriorly on smooth area. Mesoscutum and mesopleuron above precoxal sulcus in dense and rather short pale setae. Dorsal side of hind tibia with long, rather sparse and semi-erect pale setae, their length 0.5–0.8 × maximum width of tibia.

Colour. Head varying from light brown or orange to mostly dark brown with eye orbits orange to yellow. Palpi pale yellow. Scape and pedicel yellow with small dark spot laterally, flagellum brown to dark brown towards apex. Mesosoma mainly dark reddish brown or black, sometimes median lobes anteriorly and lateral lobes laterally with orange brown spots, pronotum brown ventrally. Tegula yellow or light brown. Metasoma reddish brown or black dorsally, yellow or white yellow laterally beyond first tergite and ventrally. Legs mottled dark brown and whitish yellow, fore and mid coxae, trochanter and trochantellus white or pale yellow; hind leg reddish brown to dark reddish brown, hind tibia basally pale at short distance; rarely legs almost entirely black. Ovipositor sheath dark brown, medially paler. Wings faintly and evenly infuscate, with darker spot bellow pterostigma. Pterostigma entirely and veins dark brown.

Male. Unknown.

Distribution. Costa Rica, Colombia, French Guiana.

Comparative diagnosis. This species belongs to the morphological group with widely setose mesoscutum. Pedinotus niger Marsh is morphologically similar to P. trinidad sp. nov., but it differs from the latter species by having the vertex transverse striate (rugose in P. trinidad ), head width 1.4–1.5 × its median length (1.8 × in P. trinidad ), first flagellomere 0.75–0.80 × as long as second flagellomere (0.9 × in P. trinidad ), median lobe of mesoscutum anteriorly with distinct medioanterior depression (without such depression in P. trinidad ), second segment of hind tarsus shorter (longer in P. trinidad ), mesopleuron mainly more or less densely punctate (mainly smooth in P. trinidad ), and ovipositor sheath longer (shorter in P. trinidad ).
