Petiole on T1 reddish brown, contours darkened and sublateral areas yellow-brown; T2 with median and adjacent areas brown and lateral ends yellow-brown; T3 and beyond completely brown; distally each tergum with a narrow yellowish transparent band. In lateral view, T1-2 completely yellow; T3 yellow, dorsally brown; T4 and beyond completely brown.

Description.

Head ( Fig. 103A ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.20:0.06, 0.20:0.06, 0.20:0.06), distal antennal flagellomere subequal in length with penultimate (0.11:0.05, 0.10:0.05), antenna longer than body (2.70, 2.37); antennal scrobes-frons shallow. Face flat or nearly so, with dense fine punctations, interspaces with microsculpture and longitudinal median carina present. Frons smooth. Temple wide, punctate and interspaces with microsculpture. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.10, 0.12). Malar suture absent or difficult to see. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 103A, B ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat with punctation distinct throughout, interspaces with microsculpture. Scutellum triangular, apex sloped and fused with BS, 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 short stubs delineating the area; dorsal ATS groove smooth. 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 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 relatively polished without median longitudinal carina, proximal half curved; 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 with a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep and with faintly transverse lineate sculpture; epicnemial ridge elongated more fusiform (tapering at both ends).

Legs. Ventral margin of fore telotarsus entire, but with a tiny curved seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.12, 0.08). Hind coxa with punctation only on ventral surface and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.21, 0.17), 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. 103G, H ). Fore wing with r vein curved; 2RS vein slightly convex to convex; 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 proximally tubular and distally spectral, although sometimes difficult to see; 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 present only proximally.

Metasoma ( Fig. 103A, C–F ). Metasoma laterally compressed. Petiole on T1 completely smooth and polished, with faint, satin-like sheen, parallel-sided in proximal half and then narrowing (length 0.30, maximum width 0.15, minimum width 0.07), and with scattered pubescence concentrated in the first distal third. Lateral grooves delimiting the median area on T2 distally losing definition (length median area 0.11, length T2 0.15), edges of median area polished and lateral grooves deep, median area broader than long (length 0.11, maximum width 0.15, minimum width 0.05); T2 with scattered pubescence only distally. T3 longer than T2 (0.19, 0.15) and with scattered pubescence throughout. Pubescence on hypopygium scattered.

Cocoons ( Fig. 104H ). White or brown oval cocoons with silk fibers evenly smooth. Cocoons in among the setae along the back of caterpillar.

Male

( Fig. 104 A–J ). Similar in coloration to female. The mesosoma is stouter than females.

Etymology.

Hugo L. Kons Jr. is a retired Lepidopterologist at the University of Wisconsin-Madison, WI, USA.

Distribution.

Parasitized caterpillars were collected in Costa Rica, ACG, Sector Brasilia (Moga), Sector Rincón Rain Forest (Flecha), and Sector San Cristóbal (Potrero Argentina), during June 2004 and 2009 at 320 m, 491 m, and 520 m in grassland and rain forest.

Adult parasitoid was collected in Costa Rica, ACG, Sector San Cristóbal ( Río Blanco Abajo), during April 2008.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Olceclostera amoria Druce ( Apatelodidae ) feeding on Gmelina arborea , introduced species, ( Verbenaceae ), Pleonotoma variabilis and Amphilophium paniculatum ( Bignoniaceae ). Caterpillars were collected in third and fourth instar.
