Eyes reddish (in preserved specimen) and ocelli silver. Fore and middle legs dark yellow except brown-red/reddish coxae and brown claws; hind legs dark yellow except black coxae, femora 1/3 distal brown, distal 1/3 of tibiae and tarsomeres brown, although basitarsus proximal half yellow. Petiole on T1 brown-red/reddish, contours darkened and sublateral areas yellow-brown; T2 with median and adjacent areas brown-red/reddish, these two dark areas forming a rectangle-shaped area, and lateral ends yellow-brown; T3 mostly light brown and lateral ends yellow-brown; T4 and beyond completely brown; distally each tergum with a very narrow yellowish translucent band. In lateral view, T1-3 completely yellow; T4 yellow, but dorsally brown; T5 and beyond brown. S1-2 yellow; S3-4 yellow, but medially brown, extent of brown area larger on S4 than S3; penultimate sternum and hypopygium completely brown.

Description.

Head ( Fig. 220 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.21:0.07, 0.22:0.07, 0.23:0.07), distal antennal flagellomere longer than penultimate (0.15:0.07, 0.12:0.07), antenna longer than body (3.03, 2.73); antennal scrobes-frons sloped and forming a shelf. Face flat or nearly so, punctations barely noticeable, 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 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. 220A, E, F, I ). Mesosoma dorsoventrally convex. Mesoscutum 1/4 distal with a central dent, 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 slightly convex, but on same plane as mesoscutum, phragma of the scutellum widely visible; BS only very partially overlapping the MPM; ATS demilune with faint wavy rugae; dorsal ATS groove smooth. 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 convex; MPM circular without median longitudinal carina; AFM without setiferous lobes 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 with fine sculpture and distal half with faint rugae; 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 smooth, but both dorsal and ventral furrows with short parallel carinae. Propleuron with fine rugae and dorsally with a carina. Metasternum convex. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep with faintly transverse lineate sculpture; epicnemial ridge widen.

Legs ( Fig. 220A, J ). Ventral margin of fore telotarsus entire without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.11, 0.07). Hind coxa with punctation only on ventral surface, dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.29, 0.20), hind tibia with strong spines only on distal half.

Wings ( Fig. 220K, L ). Fore wing with 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 present proximally, but absent distally.

Metasoma ( Fig. 220A, G, H, J ). Metasoma laterally compressed. Petiole on T1 distal half with faint rugae only laterally, virtually parallel-sided over most of length, but narrowing over distal 1/3 (length 0.38, maximum width 0.17, 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 0.17, length T2 0.17), edges of median area polished and lateral grooves deep, median area broader than long (length 0.17, maximum width 0.23, minimum width 0.08); T2 with pubescence in distal half. T3 longer than T2 (0.22, 0.17) and with scattered pubescence throughout. Pubescence on hypopygium scattered.

Cocoon. Unknown.

Comments.

The median area on T2 with the lateral margins curved (convex, Fig. 220G ). In some females, the black body coloration is very intense which makes the reddish tints imperceptible at first sight and the ventral furrow of the pronotum has faint parallel rugae.

Male.

Coloration similar to female. However, the coloration on hind legs differ a little: trochanter and trochantellus are yellow, but with brown tints, the femora almost completely brown, but proximally is yellow, and distal half of tibiae is brown; and the external genitalia is large and gradually narrows towards the apex.

Etymology.

Wilmer Rosendo Simbaña is an Ecuadorian gusanero who has assisted with caterpillar rearing at Yanayacu Biological Station, Ecuador.

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Yanayacu Road), during May 2009 at 2,100 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Undetermined species of Apatelodidae feeding on Dendrophorbium lloense ( Asteraceae ). Caterpillar was collected in third instar.
