Face distal half dented laterally, punctate-lacunose, interspaces wavy 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 (0.09, 0.11). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 219A, E, F, I ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout, 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, but not in the same plane, phragma of the scutellum partially exposed; BS only very partially overlapping the MPM; ATS demilune only inner side with sculpture; dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation with a smooth and shiny sloped transverse strip. Metanotum with BM wider than PFM (clearly differentiated); MPM semicircular 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 weakly curved with fine 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 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 flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep, smooth and shiny; epicnemial ridge convex, teardrop-shape.

Legs ( Fig. 219A ). Ventral margin of fore telotarsus entire without seta, fore telotarsus proximally narrow and distally wide, and longer than fourth tarsomere (0.13, 0.06). Hind coxa with punctation only on ventral surface, dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.18, 0.13), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.10, 0.10).

Wings ( Fig. 219K ). 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 not forming a 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 a small smooth area; vein 2CUa absent and vein 2CUb spectral; vein 2 cu-a absent; vein 2-1A present only proximally as tubular vein; tubular vein 1 cu-a curved, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe narrow, subdistally evenly convex and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 219A, G, H, J ). Metasoma laterally compressed. Petiole on T1 completely smooth and polished, with faint, satin-like sheen, virtually parallel-sided over most of length, but narrowing over distal 1/3 (length 0.25, maximum width 0.15, minimum width 0.06), 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 0.12, length T2 0.12), edges of median area polished and lateral grooves deep, median area broader than long (length 0.12, maximum width 0.18, minimum width 0.05), T2 with scattered pubescence only distally. T3 longer than T2 (0.17, 0.12) and with scattered pubescence throughout. Pubescence on hypopygium dense.

Cocoons. Light brown oval cocoons with evenly smooth silk fibers. Two rows of cordwood cocoons strongly adhered to the leaf substrate.

Comments.

In some specimens, the body coloration is light brown; all the sterna are light brown except that a dorsal area from S1 to S4 is yellow; the middle femora is yellow-brown; the body is slim and elongated.

Male.

Coloration similar to females; however, there are some variations: body coloration is darker than female, the middle femora is brown, the sublateral areas on T1-2 are dark reddish/dark yellow-brown. In some males, the coloration on the petiole is different: completely yellow-brown/reddish with darkened contours; in others, even in the same sample, the proximal half of the petiole is light brown and the distal half is dark brown, and the petiole has darkened contours.

Etymology.

Victoria G. Pook as a graduate student at the University of Kentucky, Lexington, KY, USA, was interested in systematics and venom composition in Ichneumonidae ( Megarhyssa : Rhyssinae).

Distribution.

The parasitized caterpillars were collected in Costa Rica, ACG, Sector Mundo Nuevo (Vado Agria and Vado Huacas), during June and August 2008 at 490 m and 560 m in dry-rain intergrade forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Paectes lunodes Guenée ( Euteliidae : Euteliinae) feeding on Ocotea veraguensis ( Lauraceae ). Caterpillars were collected in fourth instar.
