In lateral view, T1-3 completely yellow; T4 and beyond yellow, but dorsally brown, extent of brown area increasing from proximal to distal. S1-4 completely yellow; penultimate sternum and hypopygium dark brown with some spots yellow-brown. Description. <b>Head</b> (Fig. 76 A–D). Head triangular with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.28:0.09, 0.28:0.09, 0.28:0.09), distal antennal flagellomere longer than penultimate (0.15:0.06, 0.13:0.06), antenna longer than body (3.78, 2.73); antennal scrobes-frons shallow. Face flat or nearly so, with dense fine punctations, interspaces smooth and longitudinal median carina present. Frons punctate. Temple wide with punctate sculpture 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 (0.10, 0.12). Malar suture present. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally wide. <b>Mesosoma</b> (Fig. 76A, E, F, I). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout and interspaces wavy/lacunose. Scutellum triangular, apex sloped and fused with BS, scutellar punctation scattered throughout, in profile scutellum flat and on same plane as mesoscutum, phragma of the scutellum partially exposed; BS only very partially overlapping the MPM; ATS demilune with a little and complete parallel carinae; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation nearly at the same level as mesoscutum (flat) and with same kind of sculpture as mesoscutum. Metanotum with BM wider than PFM (clearly differentiated); MPM circular and bisected by a median longitudinal carina; AFM with a small lobe and not as well delineated as PFM; PFM thick and smooth; ATM proximally with semircular/undulate carina and distally smooth. Propodeum with medium-sized sculpture without median longitudinal carina, proximal half curved and distal half with a shallow dent at each side of nucha; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle distally framed by faintly concave/wavy carina; nucha surrounded by very short radiating carinae. Pronotum with a distinct dorsal furrow, dorsally with a well-defined smooth band; central area of pronotum and dorsal furrow smooth, but ventral furrow with short parallel carinae. Propleuron with fine rugae and dorsally without a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove smooth, shiny and shallow, but visible; epicnemial ridge elongated more fusiform (tapering at both ends). <b>Legs.</b> Ventral margin of fore telotarsus entire, but with a tiny curved seta, fore telotarsus proximally narrow and distally wide, and longer than fourth tarsomere (0.15, 0.09). Hind coxa finely punctate throughout, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.25, 0.17), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.17, 0.17). <b>Wings</b> (Fig. 76K). Fore wing with r vein slightly curved; 2RS vein straight; 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 straight and complete, but junction with 1-1A vein spectral. Hind wing with vannal lobe very narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin. <b>Metasoma</b> (Fig. 76A, G, H, J). Metasoma laterally compressed. Petiole on T1 finely sculptured throughout, evenly narrowing distally (length 0.40, maximum width 0.22, minimum width 0.10), and with scattered pubescence on distal half. Lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 (length median area 0.20, length T2 0.20), edges of median area obscured by weak longitudinal stripes, median area broader than long (length 0.20, maximum width 0.25, minimum width 0.10); T2 with scarce pubescence throughout. T3 longer than T2 (0.25, 0.20) and with scattered pubescence throughout. Pubescence on hypopygium dense. <b>Cocoons.</b> Stack on larval cuticle. Male (Fig. 77 A–G). Similar in coloration to female, but slimmer than female. Etymology. Edwin Narvaez is a botanist who has helped in the identification of food plants at Yanayacu Biological Station. He works at Herbario Nacional del Ecuador (QCNE), Quito, Ecuador. Distribution. Parasitized caterpillars were collected in Ecuador, Napo, Yanayacu Biological Station (Isla de Palmas, Sendero Macuculoma, Miraflores-Cosanga Forest, and Yanayacu Forest), during February 2006; and January, April, May, and September 2009 at 1,863 m, 1,973 m, 2,014 m, 2,144 m, and 2,120 m in cloud forest. Biology. The lifestyle of this parasitoid species is gregarious. Host. Undetermined species of Nymphalidae: Ithomiinae feeding on <i>Cestrum megalophyllum</i> (Solanaceae). Undetermined species of Apatelodidae feeding on <i>Columnea</i> sp., <i>C. ericae</i> and <i>Alloplectus tetragonoides</i> (Gesneriaceae). Caterpillars were collected in second and third instar.
