Diagnosis.

Median area between lateral ocelli slightly depressed ( Figs 62B , 63A ), distal antennal flagellomere subequal in length with penultimate, petiole on T1 completely smooth and polished, with faint, satin-like sheen, parallel-sided in proximal half, then narrowing ( Figs 62C, F , 63D, H ), inner margin of eyes diverging slightly at antennal sockets, propodeum without median longitudinal carina ( Figs 62C , 63C ), lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 ( Figs 62C, F , 63D, H ), and fore wing with outer side of junction of r and 2RS veins not forming a stub ( Figs 62G , 63J ).

Coloration

( Fig. 62A ). General body coloration light brown although some areas on body are light brown/reddish as propleuron, both dorsal and ventral furrows of pronotum, ventral edge of mesopleuron, mesosternum, epicnemial ridge, metepimeron, distal corners of mesoscutum, lateral edges of scutellum, lunules, BS, PFM, BM and propleuron; scape, pedicel, labrum and mandibles yellow-brown; maxillary and labial palps, and glossa yellow. Eyes gray/silver and ocelli yellowish. Fore and middle legs yellow except yellow-brown coxae and brown claws; hind legs light brown/brown except the following yellow areas: apex of coxae, trochanter, trochantellus, 1/4 proximal of tibiae, both tibial spurs and basitarsus with a proximal ring. Petiole on T1 light brown, contours darkened, and sublateral areas yellow; T2 with median area light brown, and lateral ends yellow; T3 light brown with proximal corners yellow; T4 and beyond completely light brown; distally each tergum with a narrow whitish/yellow transparent band. In lateral view, T1-2 completely yellow; T3 proximal half yellow, distal half light brown; T4 and beyond completely light brown. S1-3 yellow, medially with some light brown spots; S4 and beyond completely light brown.

Description.

Head ( Fig. 62A, B ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.15:0.05, 0.15:0.05, 0.14:0.05), distal antennal flagellomere subequal in length with penultimate (0.08:0.05, 0.07:0.05), antenna longer than body (1.86, 1.67); antennal scrobes-frons shallow. Face finely punctate, interspaces smooth, distal half dented only laterally 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 (0.07, 0.11). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 62A, B ). Mesosoma dorsoventrally convex. Mesoscutum 1/4 distal with a central dent, punctation distinct proximally, but absent/dispersed distally, interspaces with microsculpture. Scutellum triangular, apex sloped and fused with BS, scutellar punctation distinct peripherally, absent centrally, 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 complete undulate/reticulate carinae; dorsal ATS groove with semicircular/parallel carinae. 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 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, relatively polished, proximal half weakly 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 and dorsal furrow smooth, but ventral furrow 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; pecoxal groove distinct 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 (0.10, 0.05). Hind coxa with punctation only on ventral surface and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.15, 0.12), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.10, 0.07).

Wings ( Fig. 62G, H ). Fore wing with r vein slightly 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 present only proximally as tubular vein; tubular vein 1 cu-a curved, complete and touching the edge of 1-1A vein. Hind wing with vannal lobe narrow, subdistally evenly convex, subproximally straightened, and setae present only proximally.

Metasoma ( Fig. 62A, 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 0.24, maximum width 0.10, minimum width 0.05), 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 0.09, length T2 0.09), edges of median area polished and lateral grooves deep, median area broader than long (length 0.09, maximum width 0.15, minimum width 0.05); T2 with scattered pubescence only distally. T3 longer than T2 (0.16, 0.09) and with scattered pubescence only distally. Pubescence on hypopygium dense.

Cocoons. Beige oval cocoons with silk fibers evenly smooth. Cocoons glued side-by-side.

Male

( Fig. 63 A–K ). Coloration and shape similar to that of female.

Etymology.

David (Dave) Ward Roubik works at the Smithsonian Tropical Research Institute, Panama City, Panama. He is interested in understanding how tropical bee communities change through monitoring populations of bees, plants, animals, and even microbes and molecules.

Distribution.

The parasitized caterpillar was collected in Costa Rica, ACG, Sector Santa Rosa (Bosque Humedo), during July 1998 at 290 m in dry forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Undetermined species of Noctuidae ,, food plant was not reported. Caterpillar was collected in fifth instar.
