Prescutellar depression (scutellar sulcus) rather deep, long, finely rugulose, with distinct three-five carinae, 0.3–0.4 × as long as scutellum medially. Precoxal sulcus (sternaulus) very shallow, smooth and running along anterior 0.5 of lower part of mesopleuron, sometimes indistinct or completely absent.

Wings. Fore wing 4.0–4.6 × longer than maximum width. Vein r (first radial abscissa) arising almost from middle of pterostigma. Vein 3RSa (second radial abscissa) 1.6–2.0 × longer than vein r (first radial abscissa), 0.3 × as long as the straight vein 3RSb (third radial abscissa), 1.2–1.4 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell not widened apically, 2.2–2.5 × longer than maximum width, 0.60–0.75 × as long as first subdiscal (brachial) cell. Vein (RS+M)a (first medial abscissa) weakly sinuate. Vein 1m-cu (recurrent) antefurcal, subparallel to vein 1M (basal). Vein 1cu-a (nervulus) postfurcal, 0.1–0.4 × as long as distance between veins 1M (basal) and nervulus (1cu-a). First subdiscal (brachial) cell 5.0–5.8 × longer than maximum width. Hind wing vein M+CU (first submedial abscissa) 0.40–0.45 × as long as vein 1-M (second submedial abscissa). Vein mcu (recurrent) straight but weakly curved posteriorly, weakly antefurcal.

Legs. Hind femur 3.6–3.9 × longer than maximum width. Hind tarsus 1.0–1.1 × about as long as 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 0.5 × as long as basitarsus, 1.4–1.5 × longer than fifth segment (without pretarsus).

Metasoma 1.2–1.5 × longer than mesosoma and head combined. First tergite with short and wide basolateral lobes, without spiracular tubercles, almost linearly widened from subbase to apex. Length of first tergite 0.9–1.1 × its maximum (apical) with; maximum width 1.3–1.6 × its minimum (basal) width. First and second tergites perhaps immovable fused, its suture dorsally deep. Second tergite with rather wide, shallow and almost parallel sublateral furrows; median length of second tergite 0.45–0.55 × its basal width, 0.8–1.0 × median length of third tergite. Suture between second and third tergites entirely deep and rather wide, distinctly sinuate, with strong sublateral bends. Third tergite with distinct wide transverse crenulated sulcus in basal 0.20–0.25 (medially)–0.5 (laterally). Ovipositor sheath 1.0–1.2 × as long as metasoma, 1.8–2.1 × longer than mesosoma, 0.8–1.0 × as long as fore wing.

Sculpture and pubescence. Vertex smooth; frons mainly or partly smooth, weakly striate near antennal sockets, sometimes striate with dense reticulation widely or narrowly medially or almost entirely; face coarsely transverse curvedly striate, with dense rugosity between striae and only medially. Mesoscutum mainly smooth, coarsely and usually transversely straight or curvedly striate with rugulosity at least partly in medium-sized medioposterior triangle area, rarely sculpture strongly reduced or entirely absent. Mesopleuron mainly smooth. Metapleuron mainly smooth with fine and sparse punctation, weakly reticulate with transverse striation posteriorly. Propodeal areas rather distinctly delineated by carinae, basolateral areas mainly smooth but rugulose-reticulate posteriorly and along carinae, areola not or distinctly delineated, densely and coarsely areolate-reticulate; basomedian carina developed in basal 0.4–0.5 of propodeum. Hind coxa and femur smooth. First and second metasomal tergites coarsely and densely reticulate-areolate, with striation at least partly. Third to six tergites in basal 0.2–0.3 (medially)–0.5–0.6 (laterally) very densely reticulate-areolate to almost punctate, sculpture beginning finer toward apical tergites, smooth on rest margins. Vertex mainly glabrous on wide area, with very sparse short setae laterally and sometimes posteriorly. Mesoscutum mainly glabrous, with short, very sparse and semi-erect pale setae arranged along notauli, laterally and on sculptured medioposterior area. Dorsal side of hind tibia with rather long, dense and semi-erect pale setae, their length 0.6–1.0 × maximum width of tibia.

Colour. Head brownish yellow or yellow, vertex and frons usually dark brown to black, rarely head mainly black with brownish yellow lower third of temple, malar space and most part of face. Palpi brownish yellow. Antenna entirely black. Mesosoma entirely brownish yellow to light reddish brown (orange), sometimes propodeum and/or metapleuron and scutellum with prescutellar depression black or almost black. Tegula brownish yellow or yellow. Metasoma mainly black, with whitish areas: wide laterally on all tergites, wide on posterior margins on third to sixth tergites and on narrow median longitudinal stripes on second-fourth tergites, sometimes posterior margins on third to sixth tergites dark, but narrow median longitudinal stripes on second-fourth tergites yellowish brown. Fore and mid legs mainly brownish yellow or pale brown, apex of femora and bases of tibiae blackish; sometimes these legs black or dark reddish brown to reddish brown with paler or pale brown tarsi, fore coxa and sometimes trochanter and trochantellus yellow, mid coxa brownish yellow or black. Hind leg mainly black to dark brown, base and apex of hind coxa and subapical half of hind femur whitish yellow or yellow; sometimes apex of coxa and femur black, tarsus reddish brown. Ovipositor sheath entirely black. Wings entirely distinctly and evenly infuscate. Pterostigma entirely dark brown or brown.

Male. Unknown.

Distribution. Costa Rica, French Guiana, Brazil.

Etymology. Named after the mainly glabrous mesoscutum.

Comparative diagnosis. This new species belongs to the morphological group with glabrous mesoscutum. Pedinotus glabroscutum sp. nov. is very similar to P. dispar sp. nov., but differs in having the anterior half of notauli smooth (entirely or mainly crenulated in P. dispar ), body longer (shorter in P. dispar ), medio-posterior area of mesoscutum mainly with curved transverse striae and rugulosity between it (rugose-reticulate with different striae in P. dispar ), the first and second metasomal tergites longer (shorter in P. dispar ), and ovipositor sheath longer than metasoma (shorter in P. dispar ).
