Head ( Fig. 78A, B, E View Figure 78 ) Head rounded with pubescence short and dense. Proximal three antennal flagellomeres longer than wide (0.19:0.07, 0.18:0.07, 0.18:0.07), distal antennal flagellomere longer than penultimate (0.12:0.05, 0.09:0.06), antenna longer than body (2.68, 2.53); antennal scrobes-frons shallow. Face with dense fine punctations, interspaces wavy, distal half dented only laterally and longitudinal median carina present. Frons punctate. Temple wide, punctate 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, 0.14). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 78 A–D View Figure 78 ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout and interspaces wavy/lacunose. Scutellum triangular, 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 with short stubs delineating the area; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation depressed centrally 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 without setiferous lobes and not as well delineated as PFM; PFM thick and smooth; ATM proximally with semircular/undulate carina and distally smooth. Propodeum without median longitudinal carina, proximal half curved with medium-sized 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 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 smooth, but both dorsal and ventral furrows with short parallel carinae. Propleuron with fine punctations throughout and dorsally with a carina. Metasternum flat or nearly so. Contour of mesopleuron convex; precoxal groove deep with faintly transverse lineate sculpture; epicnemial ridge convex, teardrop-shaped.

Legs. Ventral margin of fore telotarsus slightly excavated and with a tiny curved seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.10, 0.06). Hind coxa with punctation only on ventral surface and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.27, 0.16), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.11, 0.10).

Wings ( Fig. 78J, K View Figure 78 ). Fore wing with r vein slightly curved; 2RS vein slightly convex to convex; r and 2RS veins forming an angle 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 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.

Comments.

Both sexes with slim bodies.

Male

( Fig. 79 A–I View Figure 79 ). Similar in coloration and shape to female.

Etymology.

Edward Osborne Wilson is considered to be the world’s leading living authority in myrmecology. He has been called "the father of sociobiology" and "the father of biodiversity".

Distribution.

Parasitized caterpillars were collected in Costa Rica, ACG, Sector Del Oro (Quebrada Trigal and Sendero Puertas), Sector El Hacha (Sendero Bejuquilla and Sendero Tigre), Sector Pitilla (Sendero Trocha), Sector Santa Rosa (Sendero Natural), during September 1992, October 1998, September and December 2003, June 2009, and November 2010 at 280 m, 290 m, 400 m, and 540 m in intergrade dry-rain forest and rain forest. Adult parasitoid was collected in Costa Rica, ACG, Sector El Hacha (Sendero Bejuquilla) during, March 1999 at 280 m in intergrade dry-rain forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Calledema plusia   Felder ( Noctuidae   : Nystaleinae  ) ( Fig. 4O View Figure 4 ) feeding on Hirtella americana   , H. guatemalensis   , H. racemosa   , H. triandra   and Licania arborea   ( Chrysobalanaceae  ). Caterpillars were collected in third and fourth instar.
