Head ( Fig. 221 A–D View Figure 221 ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.16:0.06, 0.17:0.06, 0.16:0.06), distal antennal flagellomere longer than penultimate (0.11:0.03, 0.09:0.03), antenna longer than body (2.27, 1.91); antennal scrobes-frons shallow. Face flat or nearly so, dense fine punctations, 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 (0.08, 012). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide.
Mesosoma ( Fig. 221A, E, F, I View Figure 221 ). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation distinct proximally ranging to satiny distally, interspaces with microsculpture. Scutellum triangular, apex sloped and fused with BS, but not in the same plane, scutellar punctation indistinct 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 a little, complete parallel carinae; 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, smooth and with lateral ends rounded; ATM proximally with a well-defined row of foveae and distally smooth. Propodeum without median longitudinal carina, proximal half weakly curved with fine sculpture and distal half rugose; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle distally framed by a short concave 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 a mix of rugae and fine punctation, dorsally with a carina. Metasternum flat or nearly so. Contour of mesopleuron convex; precoxal groove deep with transverse lineate sculpture; epicnemial ridge convex, teardrop-shaped.
Legs ( Fig. 221A View Figure 221 ). Ventral margin of fore telotarsus apex excavated, but without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.10, 0.06). Hind coxa with punctation only on ventral surface, dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.16, 0.11), 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, 0.09).
Wings ( Fig. 221K View Figure 221 ). Fore wing with r vein 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 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 absent; tubular vein 1 cu-a curved and complete, but junction with 1-1A vein spectral. Hind wing with vannal lobe narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.
Metasoma ( Fig. 221A, G, H, J View Figure 221 ). Metasoma laterally compressed. Petiole on T1 finely sculptured on distal half, virtually parallel-sided over most of length, but narrowing over distal 1/3 (length 0.27, maximum width 0.12, minimum width 0.09), 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 0.11, length T2 0.11), edges of median area polished and lateral grooves deep, median area broader than long (length 0.11, maximum width 0.19, minimum width 0.05), T2 with scattered pubescence only distally. T3 longer than T2 (0.15, 0.11) and with pubescence more notorious in distal half. Pubescence on hypopygium dense.
Cocoons. Oval cocoons with ordered silk fibers, covered by a net. Two rows of cordwood cocoons adhered to the leaf substrate.
In some specimens their bodies are nearly colorless; however, the lighter areas present in so called 'normal specimens’ can also be distinguished in these albinos; the petiole distally looks convex; the lateral grooves delimiting the median area on T2 are almost reaching the distal edge of T2; however, the brown coloration is not throughout the edge ( Fig. 221G, H View Figure 221 ). Some females are darker than others and the yellow coloration on T2-3 is replaced by yellow-brown; and the body is slim and elongated.
Similar in coloration to females except than in males, indeed in the same gregarious sample, the petiole is completely brown, the median area on T2 is brown with lateral ends yellow-brown, and the T3 is light brown and lateral ends with some yellow-brown spot.
Won-Young Choi was a Korean entomologist, who worked at the National Institute of Biological Resources ( NIBR), Incheon, Korea. As a graduate student at UIUC, IL, USA, he contributed especially to the knowledge of taxonomy of Diolcogaster ( Microgastrinae ) from ACG.
The parasitized caterpillars were collected in Costa Rica, ACG, Sector Rincón Rain Forest ( Estación llanura and Jacobo) and Sector Pitilla (Colocho), during August 2008, July 2009, December 2010, and July 2011 at 135 m, 375 m, and 461 m in rain forest.
The lifestyle of this parasitoid species is gregarious.
