Eyes and ocelli silver. Fore and middle legs yellow except brown claws; hind legs yellow except coxae distally yellow, femora distally with a tiny brown dot, both ends of tibiae brown, and tarsomeres brown although basitarsus proximally with a narrow yellow band. Petiole on T1 dark brown and sublateral areas yellow-brown; T2 with median area brown and lateral ends with two colorations: most of the area brown and some irregular spots yellow-brown; T3 and beyond brown; distally each tergum with a narrow yellowish transparent band. In lateral view, T1-2 yellow; T3 and beyond yellow, but dorsally brown, extent of brown area remaining constant throughout. S1-3 yellow; S4-5 yellow, but distally with a narrow longitudinal brown band; hypopygium yellow, but medially brown.

Description.

Head ( Fig. 184 A–C ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.24:0.08, 0.25:0.08, 0.25:0.08), distal antennal flagellomere longer than penultimate (0.13:0.05, 0.10:0.05), antenna longer than body (3.33, 2.63); antennal scrobes-frons sloped and forming a shelf. Face flat or nearly so, with dense fine punctations, interspaces smooth and longitudinal median carina present. Frons smooth. Temple wide, punctate and interspaces clearly smooth. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.09, 0.12). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 184A, F, G, I ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout, interspaces smooth. 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 a little, complete and parallel carinae, dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation with small and homogeneous foveae, area just behind transscutal articulation with a smooth and shiny sloped transverse strip. Metanotum with BM as same width as PFM (not clearly differentiated); MPM circular with some sculpture inside; AFM with a small lobe and not as well delineated as PFM; PFM thick, smooth and with lateral ends rounded; ATM proximally with a groove with some sculpturing and distally smooth. Propodeum with a shallow dent, proximal half weakly curved with medium-sized sculpture and distal half slightly rugose; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle without distal carina; nucha surrounded by long 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 punctations throughout and dorsally with a carina. Metasternum flat or nearly so. Contour of mesopleuron convex; precoxal groove deep, smooth and shiny; epicnemial ridge convex, teardrop-shaped.

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 (0.14, 0.08). Hind coxa with dorsal half sparsely punctate, ventral half densely punctate, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.26, 0.21), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.16, 0.12).

Wings ( Fig. 184K ). 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 forming a slight 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 microtrichiae virtually throughout; veins 2CUa and 2CUb completely spectral; vein 2 cu-a present as spectral vein, sometimes difficult to see; 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 very narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 184A, D, E, H, J ). Metasoma laterally compressed. Petiole on T1 finely sculptured only laterally, evenly narrowing distally (length 0.36, maximum width 0.21, minimum width 0.10) 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 0.17, length T2 0.17), edges of median area obscured by weak longitudinal stripes, median area as broad as long (length 0.17, maximum width 0.18, minimum width 0.09); T2 scarce pubescence throughout. T3 longer than T2 (0.22, 0.17) and with scattered pubescence only distally. Pubescence on hypopygium dense.

Cocoons. White bud-like cocoon with ridge-shaped body and evenly smooth silk fibers. Cocoons in litter or soil.

Comments.

In some females, the scape is mostly brown with some yellow areas.

Male

( Fig. 185 A–G ). The mesosoma is wider and stouter than female.

Etymology.

Paul David Hurd Jr. (2 April 1921 - 12 March 1982) was an authority on the taxonomy and biology of bees (superfamily Apoidea). He was curator at the National Museum of Natural History, Smithsonian Institution, Washington DC., USA.

Distribution.

The parasitized caterpillar was collected in Costa Rica, ACG, Sector San Cristóbal (Bosque Trampa Malaise), during January 2008 at 815 m in rain forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Rosema attenuata (Dognin) ( Notodontidae : Phalerinae) feeding on Inga oerstediana ( Fabaceae ). Caterpillar was collected in fifth instar.
