Type material. Holotype: female, “ Dominica, B. W. I., La Haut Estate, 24.XII.1978, A.T. Finnamare ” (CNIC).
Description. Female. Body length 7.8 mm; fore wing length 4.0 mm.
Head width (dorsal view) 1.5 × its median length, 1.3 × maximum width of mesoscutum. Head behind eyes (dorsal view) roundly narrowed. Eye 1.8 × longer than temple (dorsal view). Ocelli small, arranged in almost equilateral triangle. POL 1.2 × Od, 0.4 × OOL. Frons weakly concave, with fine but distinct and long median longitudinal carina. Eye glabrous, 1.2 × higher than broad. Face width 0.7 × height of eye and 0.7 × height of face and clypeus combined. Malar space 0.4 × height of eye, 1.1 × basal width of mandible. Hypoclypeal depression width 1.1 × the shortest distance between depression and eye and 0.6 × width of face.
Antenna slender, almost filiform, with more than 34 antennomeres (apical flagellomeres missing). Scape 1.3 × longer than its maximum width. First flagellomere 5.5 × longer than its apical width, 1.3 × longer than second flagellomere. Submedian flagellomeres about 5.0 × longer than their maximum width.
Mesosoma 2.0 × 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 (dorsal view), with short median longitudinal furrow anteriorly. Median length of mesoscutum 1.2 × its maximum width. Notauli complete, narrow and weakly scrobiculate. Prescutellar depression (scutellar sulcus) rather deep, finely crenulated, with three distinct carinae, and one additional indefined carina, 0.7 × as long as scutellum medially. Precoxal sulcus (sternaulus) absent.
Wings. Fore wing 4.7 × longer than maximum width. Vein r (first radial abscissa) arising almost from middle of pterostigma. Vein 3RSa (second radial abscissa) 4.0 × longer than vein r (first radial abscissa), 0.5 × as long as the straight vein 3RSb (third radial abscissa), 1.6 × longer than vein 2RS (first radiomedial). Second submarginal (radiomedial) cell 2.9 × longer than maximum width, 0.7 × as long as first subdiscal (brachial) cell. Vein (RS+M)a (first medial abscissa) weakly sinuate. Vein 1m-cu (recurrent) weakly antefurcal, subparallel to vein 1M (basal). Vein 1cu-a (nervulus) straight, about 0.2 × as long as distance between veins 1M (basal) and nervulus (1cu-a). First subdiscal (brachial) cell 6.5 × longer than maximum width. Hind wing vein M+CU (first submedial abscissa) 0.3 × as long as vein 1-M (second submedial abscissa). Vein m-cu (recurrent) almost straight and antefurcal.
Legs. Hind femur 3.1 × longer than maximum width. Hind tarsus about 1.1 × longer than hind tibia. Basitarsus of hind tarsus 0.8 × as long as second-fifth segments of hind tarsus combined; second segment. Second segment of hind tarsus 0.4 × as long as basitarsus, 1.4 × longer than fifth segment (without pretarsus).
Metasoma 1.3 × longer than mesosoma and head combined. First tergite without basolateral lobes and with spiracular tubercles, weakly and almost linearly widened from subbase to apex. Length of first tergite 0.8 × its maximum (subapical) width; maximum width 1.4 × its minimum (basal) width. Second tergite with wide, rather deep, weakly diverging apically sublateral furrows; median length of second tergite 0.45 × its basal width, 0.7 × median length of third tergite. Suture between second and third tergites shallow and rather wide, distinctly sinuate, with strong sublateral bends. Third tergite with wide transverse crenulated sulcus at basal third. Ovipositor sheath 1.3 × longer than metasoma, 2.5 × longer than mesosoma, almost as long as fore wing.
Sculpture and pubescence. Vertex costate anteriorly and smooth posteriorly; frons rugose; face areolaterugose. Mesoscutum mainly smooth, rugose in medioposterior triangle area. Mesopleuron mainly smooth ventrally and at central area, otherwise rugose, precoxal sulcus absent. Metapleuron rugose, smooth at antero-central area. Propodeal areas distinctly delineated by carinae, basolateral areas densely rugulose-lacunose, with rugosity along carinae, areola pentagonal and areolate-rugose; basomedian carina shorter than anterior fork of areola. Hind coxa and femur mainly smooth. First and second metasomal tergites rugose. Third tergite distinctly scrobiculate and punctate in basal 0.3 (medially)–0.6 (laterally) and smooth apically. Fourth to sixth tergites very densely areolaterugulose in basal 0.5, smooth on remaining parts. Vertex glabrous on wide area, with sparse short setae laterally. Mesoscutum mostly with rather dense and semi-erect pale setae. Hind tibia with long, rather sparse and semi-erect pale setae, their longest setae 0.9 × as long as maximum width of tibia.
Colour. Head mainly yellow, frons black, vertex dark brown medially, gena whitish, temple light brown, face medially and clypeus dark brown. Palpi whitish. Antenna mainly black, six basal segments brownish. Mesosoma mainly dark brown, mesopleuron orange ventrally, mesoscutal lobes brown with light yellow spots, notauli dark brown, scutellum light brown; metapleuron, propodeum and pronotum dark brown. Tegula whitish yellow. Legs light yellow to light brown; fore and mid coxa, trochanter and trochantellus white; apex of all femur and all fifth tarsal segments dark brown. Metasoma dark brown to light brown, white laterally, second tergite medio-apically and borders of semicircular area yellow; metasoma from second tergite with narrow honey yellow mediolongitudinal stripe. Ovipositor sheath dark brown. Wings hyaline. Pterostigma light brown, whitish basally.
Male. Unknown.
Distribution. Dominica.
Etymology. Named after Dominica Island, located in the Caribbean Sea, where the holotype was collected.
Comparative diagnosis. This new species belongs to the morphological group with densely setose mesoscutum. Pedinotus dominica sp. nov. is similar to P. columbianus Enderlein, but differs in having the vertex striate (without striation in P. columbianus), precoxal sulcus completely absent (present, rather distinct and crenulated in P. columbianus), and mesosoma mostly dark brown (light reddish brown with large dark brown markings in P. columbianus). Pedinotus dominica is also similar to P. niger Marsh, though it can be mainly distinguished by having a mostly glabrous vertex (densely setose in P. niger).
