Type material. <b>Holotype</b>: ECUADOR • 1♀; EC-39782, YY-A010; Napo, Yanayacu Biological Station, Sierra Azul; 2,250 m; - 0.666667, -77.947778; 06.vii.2009; CAPEA leg.; caterpillar collected in third instar; cocoons formed on 15.vii.2009; adult parasitoids emerged on 04.viii.2009; (PUCE). <b>Paratypes.</b> • 3 (1♀, 1♂) (1♀, 0♂); EC-39782, YY-A010; same data as for holotype; (PUCE). Diagnosis. Petiole on T1, proximal half straight and distal half convex (Fig. 149G), distal edge on T2 slightly convex (Fig. 149G, H), lateral grooves delimiting the median area on T2 distally losing definition (Fig. 149G), edges of median area on T2 obscured by strong longitudinal stripes (Fig. 149G, H), T3 as long as T2 (Fig. 149H), distal antennal flagellomere subequal in length with penultimate, mesoscutum punctation proximally distinct, but distally absent/dispersed (Fig. 149E), in lateral view, metasoma laterally compressed (Fig. 149A, J), dorsal outer depression on hind coxa present (Fig. 149A, J), and fore wing with r vein slightly curved, outer side of junction of r and 2RS veins forming a distinct stub (Fig. 149K). Coloration (Fig. 149 A–K). General body coloration polished black except scape proximally yellow-brown/reddish and distally brown; pedicel distally yellow-brown/reddish and proximally brown; all antennal flagellomeres dorsally lighter (light brown) than ventrally (dark brown); labrum, mandible, and tegulae dark yellow; dorsal area of low face just down between antennal scrobes, clypeus, propleuron, both ventral and dorsal furrows of pronotum, epicnemial ridge, ventral edge of mesopleuron, metasternum, distal corners of mesoscutum, dorsally ATS grove, ATS demilune, lunules, BS, and PFM with brown-red/reddish tints; glossa, maxillary and labial palps yellow. Eyes and ocelli silver. Fore and middle legs dark yellow, except tibiae and tarsomeres with a narrow dorsal strip from top to bottom; hind legs dark yellow except coxae proximally brown/brown-reddish and distally with a brown spot, femora distally with a tiny brown spot, tibiae and tarsomeres brown. Petiole on T1 brown with contours darkened, and sublateral areas yellow; T2 with median area brown and lateral areas light brown; T3 and beyond completely brown; distally each tergum with a very narrow yellow translucent band. In lateral view, T1-3 yellow; T4 and beyond brown. S1-2 yellow; S3-4 yellow, but medially brown; penultimate sternum and hypopygium brown. Description. <b>Head</b> (Fig. 149 A–D). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.20:0.06, 0.20:0.06, 0.20:0.06), distal antennal flagellomere subequal in length with penultimate (0.13:0.05, 0.12:0.06), antenna longer than body (3.13, 2.58); antennal scrobes-frons sloped and forming a shelf. Face convex, punctate-lacunose, interspaces wavy and longitudinal median carina present. Frons smooth. Temple wide, punctations barely noticeable and interspaces clearly smooth. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.07, 0.10). Malar suture absent or difficult to see. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide. <b>Mesosoma</b> (Fig. 149A, E, F, I). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct proximally, but absent/dispersed distally, interspaces smooth. Scutellum triangular, apex sloped and fused with BS, but not in the same plane, scutellar punctation scattered throughout, in profile scutellum convex and slightly higher than mesoscutum, phragma of the scutellum partially exposed; BS only very partially overlapping the MPM; ATS demilune with short stubs delineating the area; dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation with large and heterogeneous foveae, area just behind transscutal articulation sloped and with same kind of sculpture as mesoscutum. Metanotum with BM convex; MPM circular without median longitudinal carina; AFM with a small lobe and not as well delineated as PFM; PFM thick, smooth and with lateral ends rounded; ATM proximally sculptured and distally without a well delimited smooth area; propodeum without median longitudinal carina, proximal half curved with medium-sized sculpture and distal half relatively polished and with a shallow dent at each side of nucha; distal edge of propodeum with a flange at each side and without stubs, propodeal spiracle without distal carina; nucha surrounded by long radiating carinae. Pronotum virtually without trace of dorsal furrow, dorsally without a smooth band; central area of pronotum and ventral furrow smooth. Propleuron finely sculptured only ventrally and dorsally without a carina. Metasternum convex. Contour of mesopleuron straight/angulate or nearly so; precoxal groove smooth, shiny and shallow, but visible; epicnemial ridge convex, teardrop-shaped. <b>Legs.</b> Ventral margin of fore telotarsus entire without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.15, 0.07). Medially hind coxa smooth, dorsally with scattered punctation and ventrally with dense punctation, dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.22, 0.16), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.14, 0.13). <b>Wings</b> (Fig. 149K). Fore wing with r vein slightly curved; 2RS vein straight; r and 2RS veins forming an angle at their junction and outer side of junction forming a distinct stub; 2M vein straight; distally fore wing [where spectral veins are] with microtrichiae more densely concentrated than the rest of the wing; anal cell 1/3 proximally lacking microtrichiae; subbasal cell with microtrichiae virtually throughout; veins 2CUa and 2CUb completely spectral; vein 2 cu-a present as spectral vein, sometimes difficult to see; vein 2-1A proximally tubular and distally spectral, although sometimes difficult to see; tubular vein 1 cu-a straight, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe very narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin. <b>Metasoma</b> (Fig. 149A, G, H, J). Metasoma laterally compressed. Petiole on T1 with rugae all over the surface, virtually parallel-sided over most of length, but barely narrowing at apex, apex truncate (length 0.35, maximum width 0.19, minimum width 0.14), and with scattered pubescence concentrated in the first distal third. Lateral grooves delimiting the median area on T2 distally losing definition (length median area 0.14, length T2 0.19), edges of median area obscured by strong longitudinal stripes, median area broader than long (length 0.14, maximum width 0.25, minimum width 0.10); T2 with scattered pubescence only distally. T3 as long as T2 (0.18, 0.19) and with pubescence more notorious in distal half. Pubescence on hypopygium dense. <b>Cocoons.</b> Unknown. Comments. Contours of the petiole with proximal half straight and distal half convex (Fig. 149G, H); the distal edge on T2 slightly convex (Fig. 149G, H); the median area is similar to <i>Austrocotesia</i> Austin &amp; Dangerfield; the limit between the mesopleuron and the metasternum is flattened/dented; in lateral view, the eyes cover a large area of the head (Fig. 149C); the body is slim and elongated. Male. Similar in coloration to female. Etymology. Marcelo Teixeira Tavares works on the taxonomy, systematics, biology, and ecology of parasitoid wasps (Hymenoptera), with an emphasis on Chalcididae. Currently, he works at the Universidade Federal do Espirito Santo (UFES), Vitória, Brazil. Distribution. Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Sierra Azul) during July 2009 at 2,250 m in cloud forest. Biology. The lifestyle of this parasitoid species is gregarious. Host. Undetermined species of Erebidae (Arctiinae) feeding on <i>Monnina subspeciosa</i> (Polygalaceae). Caterpillar was collected in third instar.
