Petiole on T1 completely smooth and polished, with faint, satin-like sheen ( Fig. 223G, H ), vertex in lateral view pointed or nearly so ( Fig. 223C ), scutellar punctation scattered throughout ( Fig. 223F ), phragma of the scutellum partially exposed ( Fig. 223F ), median area on T2 broader than long, lateral grooves delimiting the median area clearly defined and reaching the distal edge of T2, edges of median area polished and followed by a deep groove ( Fig. 223G, H ), anterior furrow of metanotum with a small lobe, without setae ( Fig. 223F ), axillary trough of scutellum almost smooth ( Fig. 223F ), propodeum without median longitudinal carina ( Fig. 223F ), anteroventral contour of mesopleuron convex ( Fig. 223A, I ), and fore wing with r vein curved, outer side of junction of r and 2RS veins forming a slight stub ( Fig. 223K ).

Coloration

( Fig. 223 A–L ). General body coloration black except labrum, mandibles, glossa, and tegulae yellow-brown; scape and pedicel yellow-brown, but laterally brown; first four-five proximal antennal flagellomeres dorsally lighter (light brown) than ventrally (dark brown), remaining flagellomeres dark brown on both sides; maxillary and labial palps pale yellow/ivorish; apex of propleuron yellow; clypeus, area just below antennal scrobes, pronotum, epicnemial ridge, ventral edge of mesopleuron, distal corners of mesoscutum, lunules, BS, PFM, and lateral ends of metapleuron with brown-red/reddish tints. Eyes silver and ocelli yellowish. Fore and middle legs light yellow except brown claws; hind legs light yellow except femora distally with tiny a dorsal brown spot, distal 1/3 of tibiae brown and proximally with a tiny brown area, and tarsomeres brown although basitarsus proximal half yellow. Petiole on T1 brown-red/reddish, contours darkened and sublateral areas yellow; T2 with median and adjacent areas brown-red/reddish, adjacent area with contours well-defined, both dark areas forming a rectangle-shaped area, and lateral ends yellow; T3 mostly brown, that dark area coinciding with the width of dark area formed by both median and adjacent areas on T2, and lateral ends narrow and yellow; T4 and beyond completely brown; distally each tergum with a narrow whitish transparent band. In lateral view, T1-3 yellow; T4 and beyond brown. S1-3 yellow; S4 yellow, but medially brown; penultimate sternum and hypopygium brown.

Description.

Head ( Fig. 223 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.26:0.07, 0.28:0.07, 0.28:0.07), distal antennal flagellomere longer than penultimate (0.15:0.06, 0.12:0.06), antenna longer than body (3.53, 2.83); antennal scrobes-frons sloped and forming a shelf. Distal half of face dented laterally, finely punctate-lacunose, interspaces wavy and longitudinal median carina present. Frons smooth. Temple wide, punctate 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, 0.13). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 223A, F, I ). Mesosoma dorsoventrally convex. Mesoscutum poximally convex and distally flat, punctation distinct proximally, but absent/dispersed distally, interspaces wavy/lacunose. Scutellum triangular, apex sloped and fused with BS, but not in the same plane, 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 almost smooth; dorsal ATS groove smooth. Transscutal articulation with small and homogeneous foveae, area just behind transscutal articulation nearly at the same level as mesoscutum (flat), smooth and shiny. Metanotum with BM wider than PFM (clearly differentiated); 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 with a groove with some sculpturing and distally smooth. Propodeum without median longitudinal carina, proximal half weakly curved with fine 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 distally framed by faintly concave/wavy carina; nucha surrounded by very short radiating carinae. Pronotum with a faint 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 convex, teardrop-shaped.

Legs ( Fig. 223A ). Ventral margin of fore telotarsus entire without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.13, 0.08). Hind coxa with punctation only on dorsal surface, dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.31, 0.23), 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).

Wings ( Fig. 223K, L ). Fore wing with r vein 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; vein 2CUa absent and vein 2CUb spectral; vein 2 cu-a absent; 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 narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 223A, G, H, J ). Metasoma laterally compressed. Petiole on T1 completely smooth and polished, with faint, satin-like sheen, parallel-sided in proximal half and then narrowing (length 0.42, maximum width 0.18, minimum width 0.08), 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 0.16, length T2 0.16), edges of median area polished and lateral grooves deep, median area broader than long (length 0.16, maximum width 0.20, minimum width 0.08); T2 with pubescence in distal half. T3 longer than T2 (0.24, 0.16) and with pubescence more notorious in distal half. Pubescence on hypopygium dense.

Cocoons ( Fig. 223E ). Gray or black oval cocoon with ordered silk fibers, but covered by a net.

Comments.

The coloration of the hind coxae is completely yellow ( Fig. 223A, J ), the body is stout, but elongated and covered by dense pubescence that may impede to see the sculpture on the body ( Fig. 223A ), and the limit between the mesopleuron and the metasternum is flattened.

Male.

Unknown.

Etymology.

Yanayacu Biological Station and Center for Creative Studies is an area of 100 hectares in the cloud forest of Ecuador, and the core site for much of our inventory work in the eastern Andes.

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Stream trail), during August 2009 at 2,114 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is solitary.

Host.

Undetermined species of Noctuidae feeding on Diplazium costale var. robustum ( Dryopteridaceae ). Caterpillar was collected in third instar.
