Type material. <b>Holotype</b>: ECUADOR • 1♀; EC-42101, YY-A123; Napo, Yanayacu Biological Station, Stream trail, Plot 442; cloud forest; 2,444 m; - 0.6015, -77.886444; 09.ix.2009; Luis Salagaje leg.; caterpillar collected in second instar; cocoon formed on 16.ix.2009; adult parasitoid emerged on 08.x.2009; (PUCE). Diagnosis. Malar suture absent or difficult to see (Fig. 150B), median area between lateral ocelli slightly depressed (Fig. 150D), propodeum with a median longitudinal dent, but no trace of median longitudinal carina (Fig. 150G), scutellar punctation distinct throughout (Fig. 150F, G), axillary trough of metanotum proximally with sculpture, but dorsally without a well delimited smooth area (Fig. 150F, G), anterior furrow of metanotum with a small lobe without setae (Fig. 150G), petiole on T1 parallel-sided in proximal half, then narrowing (Fig. 150H), edges of median area on T2 obscured by weak longitudinal stripes (Fig. 150H, I), dorsal outer depression on hind coxa present, and fore wing with r vein curved, outer side of junction of r and 2RS veins forming a distinct stub (Fig. 150L). Coloration (Fig. 150 A–M). General body coloration black except scape and all antennal flagellomeres (on both sides) brown; pedicel brown, but distally brown-red/reddish; labrum, mandibles, propleuron apically with a small spot, and dorsal furrow of pronotum with brown-red/reddish tints; glossa, maxillary and labial palps, and tegulae light yellow-brown. Eyes silver and ocelli reddish/silver (in preserved specimen). Fore and middle legs light yellow-brown although coloration from tibiae to tarsomeres more intense, and claws brown, both femora and tibiae of middle legs with a lighter narrow dorsal brown strip from top to bottom; hind legs yellow-brown except black coxae distally yellow, femora distally with a small brown spot, additionally with a narrow, dorsal, light brown strip from top to bottom, distal half of tibiae brown and proximally with a brown ring, and tarsomeres brown. Petiole on T1 dark brown and sublateral areas yellow-brown; T2 with median and adjacent areas dark brown, and narrow lateral ends yellow-brown; T3 and beyond complete dark brown; distally each tergum with a narrow whitish transparent band. In lateral view, T1-2 yellow; T3-4 yellow, but dorsally brown, the extent of brown area increasing from proximal to distal; T5 and beyond completely brown. S1-3 yellow; S4-5 brown, but distally with a narrow yellow band; hypopygium brown. Description. <b>Head</b> (Fig. 150 A–D). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.25:0.08, 0.25:0.08, 0.25:0.08), distal antennal flagellomere longer than penultimate (0.14:0.07, 0.10:0.07), antenna longer than body (3.48, 2.68); antennal scrobes-frons sloped and forming a shelf. Face with depression only laterally, dense fine punctations, interspaces smooth 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 (0.10, 0.20). Malar suture absent or difficult to see. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide. <b>Mesosoma</b> (Fig. 150A, F, G, J). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation distinct throughout, interspaces smooth. Scutellum long and slender, 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 only very partially overlapping the MPM; ATS demilune inner side with a row of foveae; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and homogeneous foveae, area just behind transscutal articulation with a sloped transverse strip and with same kind of sculpture as mesoscutum. Metanotum with BM wider than PFM (clearly differentiated); MPM oval/circular with a short proximal carina; AFM with a small lobe and not as well delineated as PFM; PFM thick, smooth and with lateral ends rounded; ATM proximally with sculpture distally without a well delimited smooth area. Propodeum with a median longitudinal dent, but no trace of median longitudinal carina, proximal half curved with medium-sized sculpture and distal half with medium-sized punctation; 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 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 punctations throughout and dorsally without a carina. Metasternum convex. Contour of mesopleuron convex; precoxal groove deep, smooth and shiny; epicnemial ridge elongated more fusiform (tapering at both ends). <b>Legs.</b> Ventral margin of fore telotarsus slightly excavated and with a tiny curved seta, fore telotarsus proximally narrow and distally wide, and longer than fourth tarsomere (0.15, 0.10). Hind coxa with medium-size punctate throughout and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.27, 0.23), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.20, 0.14). <b>Wings</b> (Fig. 150L, M). 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 absent proximally but scattered distally. <b>Metasoma</b> (Fig. 150A, H, I, K). Metasoma laterally compressed. Petiole on T1 with a mix of fine rugae and punctate sculpture over most of the surface, parallel-sided in proximal half and then narrowing (length 0.38, maximum width 0.20, minimum width 0.12), 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 0.18, length T2 0.18), edges of median area obscured by weak longitudinal stripes, median area broader than long (length 0.18, maximum width 0.24, minimum width 0.10); T2 scarce pubescence throughout. T3 longer than T2 (0.23, 0.18) and with scattered pubescence throughout. Pubescence on hypopygium dense. <b>Cocoon</b> (Figs 4C, 150E). White oval cocoon with evenly smooth silk fibers. Comments. The antenna is curled; the ovipositor is large as in <i>Sathon</i> and with pubescence distally (Fig. 150A, K). Male. Unknown. Etymology. Marc E. Epstein is the Senior Insect Biosystematist for Lepidoptera at the California Department of Food &amp; Agriculture, Plant Pest Diagnostics Branch, Sacramento, CA, USA. He is a specialist in Limacodidae and related families (Zygaenoidea). Distribution. Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Stream trail), during September 2009 at 2,444 m in cloud forest. Biology. The lifestyle of this parasitoid species is solitary. Host. Undetermined species of Pyralidae feeding on Diplazium costale var. robustum (Dryopteridaceae). Caterpillar was collected in second instar.
