Type material. <b>Holotype</b>: ECUADOR • 1♀; EC-43790, YY-A188; Napo, Yanayacu Biological Station, Sendero Baboo; cloud forest; 2,051 m; - 0.583333, -77.897778; 26.xi.2009; CAPEA leg.; caterpillar collected in fourth instar; cocoons formed on 07.xii.2009; adult parasitoids emerged on 21.xii.2009; (PUCE). Diagnosis. Petiole on T1 distally with lateral margins relatively straight, parallel-sided in proximal half then narrowing (Fig. 215H, I), mesoscutum punctation distinct throughout (Fig. 215F), dorsal furrow of pronotum without a smooth band (Fig. 215C, J), precoxal groove deep, smooth and shiny (Fig. 215J), dorsal carina delimiting a dorsal furrow on propleuron absent (Fig. 215C), anteroventral contour of mesopleuron straight/angulate or nearly so (Fig. 215J), edges of median area on T2 polished and followed by a deep groove (Fig. 215H), and fore wing with r vein curved, outer side of junction of r and 2RS veins forming a distinct stub (Fig. 215L). Coloration (Fig. 215 A–M). General body coloration polished black except yellow-brown scape dorsally with a brown ring; pedicel yellow-brown; first five-six proximal antennal flagellomeres dorsally lighter (light brown) than ventrally (dark brown), remaining flagellomeres dark brown on both sides; labrum and mandible brown-red; glossa, maxillary and labial palps, and tegulae light yellow-brown. Eyes silver and ocelli reddish (in preserved specimen). Fore and middle legs light yellow-brown, except brown claws; hind legs light yellow-brown except coxae proximally 1/3 brown/black, femora distally with a tiny brown spot, tibiae distal half brown and proximally with a brown band, and tarsomeres brown. Petiole on T1 brown, although proximally with some brown-red tints, contours darkened and sublateral areas yellow; T2 with median and adjacent areas brown, adjacent area with contours well-defined, both dark areas forming a rectangle-shaped area, and lateral ends yellow-brown; T3 brown, corners of lateral ends proximally with brown-reddish tints; T4 and beyond completely brown; distally each tergum with a very narrow whitish translucent band. In lateral view, T1-2 yellow; T3-4 yellow, but dorsally brown, extent of brown area larger on T4 than T3; T5 and beyond brown. S1-2 yellow; S3-4 yellow, but medially brown, remaining sterna brown. Description. <b>Head</b> (Fig. 215 A–D). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.27:0.08, 0.29:0.08, 0.28:0.08), distal antennal flagellomere longer than penultimate (0.18:0.06, 0.15:0.06), antenna longer than body (3.23, 2.78); antennal scrobes-frons shallow. Face with punctations barely noticeable, distal half dented only laterally, interspaces smooth and longitudinal median carina present. Frons smooth. Temple wide, punctate-lacunose and interspaces wavy. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL subequal in length with OOL (0.10, 0.11). Malar suture faint. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide. <b>Mesosoma</b> (Fig. 215A, F, G, J). Mesosoma dorsoventrally convex. Mesoscutum with narrow grooves/dents taking the place of notauli, punctation distinct throughout, interspaces wavy/lacunose. Scutellum triangular, apex sloped and fused with BS, but not in the same plane, scutellar punctation distinct throughout, in profile scutellum flat and on same plane as mesoscutum, phragma of the scutellum partially exposed; BS mostly overlapping the MPM; ATS demilune with short stubs delineating the area; dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation sloped and with same kind of sculpture as mesoscutum. Metanotum with BM convex; MPM semicircular 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 with a groove with some sculpturing and distally smooth; propodeum without median longitudinal carina; proximal half straight or nearly so and with medium-sized sculpture and distal half relatively polished; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle without distal carina; nucha surrounded by very short radiating carinae. Pronotum virtually without trace of dorsal furrow, dorsally without a smooth band; short parallel carinae only in ventral furrow. Propleuron with a mix of rugae and fine punctation, dorsally without a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep, smooth and shiny; epicnemial ridge widen. <b>Legs</b> (Fig. 215A, J, K). 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 (0.31, 0.21), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.15, 0.14). <b>Wings</b> (Fig. 215L, M). Fore wing with r vein curved; 2RS vein slightly convex to convex; r and 2RS veins forming a weak, even curve at their junction and outer side of junction forming a slight stub; 2M vein slightly curved/swollen; 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 curved, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe very narrow, subdistally and subproximally straightened, and setae present proximally, but absent distally. <b>Metasoma</b> (Fig. 215A, H, I, K). Metasoma laterally compressed. Petiole on T1 finely sculptured laterodistally, parallel-sided in proximal half and then narrowing (length 0.36, maximum width 0.18, minimum width 0.09) and with scattered pubescence concentrated in the first distal third. Lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 (length median area 0.15, length T2 0.15), edges of median area polished and lateral grooves deep, median area broader than long (length 0.15, maximum width 0.20, minimum width 0.07); T2 with scattered pubescence throughout. T3 longer than T2 (0.22, 0.15) and with scattered pubescence throughout. <b>Cocoons</b> (Fig. 215E). White or beige oval cocoon with silk fibers messy/disordered/fluffy. Comments. The BM is convex and punctate (Fig. 215G), the limit between the mesopleuron and the metasternum forming a flattened area, and the body is elongate and slim (Fig. 215A). Female. Unknown. Etymology. Thibaut Dominique Delsinne is a French ecologist. His major fields include insect taxonomy, species diversity, ecology, and evolution. Currently, he is working as entomologist at the Société d'Histoire Naturelle Alcide d'Orbigny, France. Distribution. Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Sendero Baboo), during November 2009 at 2,051 m in cloud forest. Biology. The lifestyle of this parasitoid species is solitary. Host. Undetermined species of Geometriidae feeding on <i>Chusquea scandens</i> (Poaceae). Caterpillar was collected in fourth instar.
