( Fig. 1 )

Type material. Holotype: female, “ Avispas , 400 m, Peru, Madre de Dios Dept., Sept. 12–20, 1962, L.E. Peña ” ( CNCI).

Description. Female. Body length 8.1 mm; fore wing length 5.4 mm.

Head width (dorsal view) 1.5 × its median length, 1.2 × maximum width of mesoscutum. Head behind eyes (dorsal view) roundly narrowed. Eye 2.2 × longer than temple (dorsal view). Ocelli small, medium-sized, arranged in almost equilateral triangle. POL 0.8 × OD, 0.4 × OOL. Frons concave, with distinct and long median longitudinal carina. Eyes 1.3 × higher than broad. Face width 0.6 × height of eye and 0.7 × height of face and clypeus combined. Malar space 0.2 × height of eye, 1.3 × basal width of mandible. Hypoclypeal depression width 1.5 × the shortest distance between depression and eye, 0.6 × width of face.

Antenna slender, with 38 antennomeres. Scape 1.2 × longer than its maximum width. First flagellomere 4.2 × longer than its apical width, 1.2 × longer than second flagellomere. Submedian flagellomeres about 3.8 × longer than their maximum width.

Mesosoma 2.1 × longer than its maximum height. Pronotum distinctly convex dorsally (lateral view) and with fine submedian pronotal carina (dorsal view). Median lobe of mesoscutum distinctly protruding forwards and anteriorly weakly convex, without median longitudinal furrow. Notauli complete, entirely rather deep, weakly crenulated anteriorly. Median length of mesoscutum 1.1 × its maximum width. Prescutellar depression (scutellar sulcus) rather deep, finely crenulated, with distinct seven carinae, 0.3 × as long as scutellum medially. Precoxal sulcus (sternaulus) shallow but distinct, rather short, smooth, running along 0.2 of lower part of mesopleuron.

Wings. Fore wing 5.6 × longer than maximum width. Vein r (first radial abscissa) arising about from middle of pterostigma. Vein 3RSa (second radial abscissa) 1.7 × longer than vein r (first radial abscissa), 0.3 × as long as the straight vein 3RSb (third radial abscissa), 1.5 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell 2.2 × longer than maximum width, 0.6 × as long as first subdiscal (brachial) cell. Vein (RS+M)a (first medial abscissa) sinuate. Vein 1m-cu (recurrent) antefurcal, parallel to vein 1M (basal). Vein 1cu-a (nervulus) slightly postfurcal, about 0.2 × as long as distance between vein 1RS (basal) and 1cu-a (nervulus). Hind wing vein M+CU (first submedial abscissa) 0.4 × than vein 1M (second submedial abscissa). Vein m-cu (recurrent) almost straight and interstitial.

Legs. Hind femur 4.7 × longer than maximum width. Hind tarsus 1.1 × longer than hind tibia. Basitarsus of hind tarsus 0.8 × as long as second-fifth segments combined. Second segment of hind tarsus 0.5 × as long as basitarsus, 2.0 × longer than fifth segment (without pretarsus).

Metasoma 1.1 × longer than head and mesosoma combined. First tergite with basolateral lobes and without spiracular tubercles, weakly linearly widened from subbase to apex. Length of first tergite 0.9 × its maximum (subapical) width; maximum width 1.25 × its minimum (basal) width. Second tergite with distinct subparallel sublateral furrows; median length of second tergite 0.7 × its basal width, 1.1 × median length of third tergite. Suture between second and third tergites deep, wide and propodeal areola completely absent (partly present in P. columbianus ),crenulated. Third tergite with wide and rather shallow transverse crenulated depression at basal third. Ovipositor sheath 1.2 × longer than metasoma, 1.9 × longer than mesosoma, 0.8 × as long as fore wing.

Sculpture and pubescence. Vertex smooth, frons weakly costate near antennal sockets; face costate laterally, rugose medially. Mesoscutum mainly smooth, costate in medioposterior triangle area. Mesopleuron smooth, subalar sulcus smooth anteriorly and rugose posteriorly. Metapleuron almost smooth, weakly rugose posteriorly. Propodeal areas distinctly delineated by carinae, basolateral areas areolate-rugose, areola pentagonal and areolaterugose; basomedian carina short. Hind coxa and femur mainly smooth. First metasomal tergite rugose; second tergite with median costate-rugose area; third tergite smooth apically and areolate-rugose basally. Remaining tergites finely areolate basally and smooth apically. Vertex mainly glabrous. Mesoscutum mostly glabrous, with sparse short setae along notauli, laterally and on sculptured area. Dorsal side of hind tibia with long, rather sparse and semi-erect pale setae, length of longest setae about 1.2 × maximum width of tibia.

Colour. Body mainly orange, head, antenna and legs (except orange fore coxa) black. Palpi mainly dark brown, apical segments paler. All tarsi and metasoma apically dark brown. Ovipositor sheath dark brown. Wings faintly and evenly infuscate. Pterostigma dark brown.

Male. Unknown.

Distribution. Peru.

Etymology. Named after type locality where holotype was collected.

Comparative diagnosis. This new species belongs to the morphological group with mainly glabrous mesoscutum. Pedinotus avispas sp. nov. is similar to P. haliti sp. nov. and P. nigriceps sp. nov. New species differs from P. haliti in having the palpi mostly dark brown (entirely pale yellow in P. haliti ), medioposterior area of mesoscutum coarsely rugulose (mostly smooth in P. haliti ), frons mainly smooth (with striation in P. haliti ), and antenna with 38 segments (51 segments in P. haliti ). The differences between Pedinotus avispas and P. nigriceps are shown in the key.
