Head ( Fig. 52A, B, E View Figure 52 ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.17:0.06, 0.17:0.06, 0.16:0.06), distal antennal flagellomere longer than penultimate (0.11:0.05, 0.09:0.05), antenna longer than body (2.27, 2.17); antennal scrobes-frons shallow. Face punctate-lacunose, interspaces with microsculpture, distal half dented only laterally, and longitudinal median carina present. Frons smooth. 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, 0,11). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide.
Mesosoma ( Fig. 52 A–C, E View Figure 52 ). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation distinct proximally and with polished area distally, and interspaces wavy/lacunose. Scutellum triangular, apex sloped and fused with BS, scutellar punctation distinct throughout, in profile scutellum slightly convex, but 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 with a smooth and shiny sloped transverse strip. Metanotum with BM wider than PFM (clearly differentiated); MPM circular without 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 weakly curved with medium-sized 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 smooth, but both dorsal and ventral furrows with short parallel carinae. Propleuron with fine rugae and dorsally without a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep with faintly transverse lineate sculpture; epicnemial ridge convex, teardrop-shaped.
Legs. Ventral margin of fore telotarsus entire, but with a tiny curved seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.11, 0.06). Hind coxa with punctation only on ventral surface and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.20, 0.16), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.14, 0.11).
Wings ( Fig. 52I, J View Figure 52 ). 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 not forming a 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 a small smooth area; 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 only proximally.
Metasoma ( Fig. 52A, D, F–H View Figure 52 ). Metasoma laterally compressed. Petiole on T1 finely sculptured only laterally, virtually parallel-sided over most of length, but narrowing over distal 1/3, apex truncate (length 0.25, maximum width 0.13, minimum width 0.05), petiole 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 0.15, length T2 0.15 mm), edges of median area polished and lateral grooves deep, median area broader than long (length 0.15, maximum width 0.17, minimum width 0.05), T2 with scattered pubescence only distally. T3 longer than T2 (0.19 0.15) and with scattered pubescence only distally. Pubescence on hypopygium dense.
Cocoons ( Fig. 4Q View Figure 4 ). Brown or gray oval cocoons with silk fibers evenly smooth. Cocoons arranged in two rows of cordwood on each side of the caterpillar cadaver.
The minimum wide on median area on T2 has a fold, at first glance looks like the edges are not well-defined.
( Fig. 53 A–I View Figure 53 ). The coloration similar to that of females and the metasoma is thinner than in females.
D. Christopher (Chris) Darling is a senior curator of Entomology in the Department of Natural History at the Royal Ontario Museum ( ROM), Toronto, Ontario, Canada. He is a world authority on the taxonomy of the Perilampidae ( Chalcidoidea) and he has focused upon understanding the diversity and evolutionary relationships of these wasps.
The parasitized caterpillars were collected in Costa Rica, ACG, Sector San Cristóbal (Sendero Pinyal and Vado Río Cucaracho), during June of 2003 and 2006 at 630 m and 640 m in rain forest.
The lifestyle of this parasitoid species is gregarious.
