Material examined. Costa Rica: 1 female (paratype), Heredia Province, La Selva Biological Station , 3 km S Puerto Viejo, 10º26'N, 84º01'W, 7.IV.1989, H. Hespenheide coll. ( UWIM) .

Redescription. Female. Body length 8.2 mm; fore wing length 6.0 mm.

Head width (dorsal view) 1.45 × its median length, 1.25 × maximum width of mesoscutum. Head behind eyes (dorsal view) roundly narrowed. Eye 1.7 × longer than temple (dorsal view). Ocelli small, arranged in almost equilateral triangle. POL 0.8 × Od, 0.4 × OOL. Frons concave, with fine median longitudinal and rather indistinct posteriorly carina. Eye glabrous, 1.3 × higher than broad. Malar space 0.4 × height of eye, 0.75 × basal width of mandible. Face width 0.9 × height of eye and about equal to height of face and clypeus combined. Hypoclypeal depression width 1.1 × the shortest distance between depression and eye and 0.5 × width of face.

Antenna slender, almost filiform, with 41 antennomeres. Scape 1.6 × longer than its maximum width. First flagellomere about 5.0 × longer than its apical width, about as long as second flagellomere. Submedian flagellomeres about 2.5 × longer than their maximum width.

Mesosoma 2.2 × longer than its maximum height. Pronotum distinctly convex dorsally (lateral view) and with fine irregular submedian pronotal carina (dorsal view). Median lobe of mesoscutum weakly protruding forwards and anteriorly weakly convex, without median longitudinal furrow. Median length of mesoscutum 1.15 × its maximum width. Notauli complete, deep anteriorly and shallow posteriorly, crenulated. Prescutellar depression (scutellar sulcus) rather deep, rugulose, with five distinct carinae, 0.3 × as long as scutellum medially. Precoxal sulcus (sternaulus) completely absent.

Wings. Fore wing about 4.0 × longer than maximum width. Vein r (first radial abscissa) arising before middle of pterostigma. Vein 3RSa (second radial abscissa) 1.8 × longer than vein r (first radial abscissa), 0.4 × as long as the straight vein 3RSb (third radial abscissa), 1.8 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell 2.5 × longer than maximum width, 0.75 × as long as first subdiscal (brachial) cell. Vein (RS+M)a (first medial abscissa) strongly sinuate. Vein 1m-cu (recurrent) weakly antefurcal, subparallel to vein 1M (basal). Vein 1cu-a (nervulus) almost interstitial. Hind wing vein M+CU (first submedial abscissa) 0.35 × as long as vein 1-M (second submedial abscissa). Vein m-cu (recurrent) almost straight and distinctly antefurcal.

Legs. Hind femur 3.5 × longer than maximum width. Hind tarsus about as long as hind tibia. Basitarsus of hind tarsus 0.7 × as long as second-fifth segments of hind tarsus combined. Second segment of hind tarsus 0.5 × as long as basitarsus, 1.5 × longer than fifth segment (without pretarsus).

Metasoma 1.1 × longer than mesosoma and head combined. First tergite with small basolateral lobes, linearly widened from subbase to apex. Length of first tergite about equal to its maximum (subapical) width; maximum width 1.3 × its minimum (basal) width. First and second tergites perhaps immovable fused, its suture dorsally rather deep and wide. Second tergite with sublateral furrows very shallow, virtually absent. Median length of second tergite 0.55 × its basal width, about equal to median length of third tergite. Suture between second and third tergites entirely deep and rather wide, distinctly sinuate, with strong sublateral breaks. Third tergite with distinct but shallow transverse sulcus at basal third, finely and weakly crenulated. Ovipositor sheath 1.1 × longer than metasoma, 1.8 × longer than mesosoma, 0.9 × as long as fore wing.

Sculpture and pubescence. Vertex and frons smooth; face coarsely rugose-striate. Mesoscutum smooth, rugulose in medioposterior subtriangle area. Mesopleuron and metapleuron mostly smooth, mesopleuron rugulose posteriorly. Propodeal areas distinctly delineated by carinae, basolateral areas mainly smooth; areola pentagonal and rugulose; basomedian carina about as long as anterior fork of areola. Hind coxa and femur smooth. First and second metasomal tergites rugose-costate. Third tergite reticulate-striate laterally, finely striate-rugose sublaterally and smooth medially, apically smooth; fourth and fifth tergites small reticulate-punctate in basal halves, smooth on remaining parts. Vertex and mesoscutum mainly glabrous. Dorsal side of hind tibia with long, rather sparse and semi-erect pale setae, their length 0.7–0.9 × maximum width of tibia.

Colour. Head mainly black, light reddish brown in dorso-anterior area near eye. Palpi pale brown. Antenna black. Mesosoma mainly bright orange, propleuron and pronotal colar black. Tegula orange. Metasoma orange, more or less dark brown apically. Legs mainly black, trochanters and trochantelli yellow, tarsi brown; mid leg darker than fore leg, hind leg darker than middle leg; hind tibia yellow at base. Ovipositor sheath entirely black. Wings faintly and evenly infuscate. Pterostigma and veins yellowish.

Male. Unknown.

Distribution. Costa Rica.

Comparative diagnosis. This species belongs to the morphological group with glabrous mesoscutum. Pedinotus rojasi Marsh is similar to P. levigatus Marsh , P. avispas sp. nov. and P. haliti sp. nov.. This species differ from P. avispas by having the propleuron and part of pronotum black (mesosoma entirely orange in P. avispas ) and ovipositor sheath about as long as metasoma (much longer in P. avispas ). Pedinotus rojasi differs from P. haliti by having distinctly crenulated notauli (smooth in P. haliti ) and vein 1cu-a (nervulus) interstitial (distinctly postfurcal in P. haliti ). Finally, P. rojasi differs from P. levigatus by having the completely sculptured first and second metasomal tergites and basal parts of third to fifth tergites (metasoma almost completely smooth in P. levigatus ).
