Proximal three antennal flagellomeres longer than wide (0.17:0.08, 0.17:0.08, 0.17:0.08), distal antennal flagellomere longer than penultimate (0.11:0.07, 0.08:0.07), antenna longer than body (2.53, 2.22); antennal scrobes-frons shallow. Face with depression only laterally, dense fine punctations, interspaces with microsculpture 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 (0.08, 0.12). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide.
Mesosoma ( Fig. 154 A–C, EView Figure 154). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct proximally with polished area distally, interspaces with microsculpture. Scutellum triangular, apex sloped and fused with BS, scutellar punctation distinct peripherally and absent centrally, in profile scutellum flat and on same plane as mesoscutum, phragma of the scutellum partially exposed; BS mostly overlapping the MPM; ATS demilune with quite a little complete parallel carinae; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and homogeneous foveae, area just behind transscutal articulation smooth, shiny and depressed centrally. Metanotum with BM wider than PFM (clearly differentiated); MPM circular/semicircular without median longitudinal carina; AFM without setiferous lobes and not as well delineated as PFM; PFM thick, smooth and with a distal flat flange; ATM proximally with sculpture distally without a well delimited smooth area.

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 transverse lineate sculpture; epicnemial ridge elongated more fusiform (tapering at both ends).
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, 0.05). Hind coxa with punctation only on ventral surface and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.21, 0.15), 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. 154I, JView Figure 154). 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 and subproximally straightened, and setae present proximally, but absent distally.
Metasoma ( Fig. 154A, D, F–HView Figure 154). Metasoma laterally compressed. Petiole on T1 finely sculptured only laterally, parallel-sided in proximal half and then narrowing (length 0.32, maximum width 0.18, minimum width 0.10), and with scattered pubescence concentrated in the first distal third. Lateral grooves delimiting the median area on T2 distally losing definition (length median area 0.10, length T2 0.13), edges of median area polished and lateral grooves deep, median area broader than long (length 0.10, maximum width 0.23, minimum width 0.10); T2 with scattered pubescence only distally. T3 longer than T2 (0.17, 0.13) and with scattered pubescence throughout. Pubescence on hypopygium dense.
Cocoons. Light gray or white oval cocoons with ordered silk fibers, but covered by a net. Cocoons forming two rows of cordwood on each side of the caterpillar adhered to the leaf substrate.
( Fig. 155 A–JView Figure 155). Body shape similar to female; however, male without tricolored petiole, instead it is completely light brown although the contours are darkened.
Mark R. Shaw works on the natural history and systematics of Lepidoptera and parasitioid wasps at the National Museums of Scotland, U.K.
The parasitized caterpillars were collected in Costa Rica, ACG, Sector Del Oro (Quebrada Romero and Uncaria) and Sector Mundo Nuevo (Sendero Puertas), during June 2005, January 2006, and October 2007 at 370 m, 400 m, and 490 m in dry-rain intergrade forest.
The lifestyle of this parasitoid species is gregarious.
