Description.

Head ( Fig. 212 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.22:0.65, 0.23:0.65, 0.22:0.65), distal antennal flagellomere longer than penultimate (0.14:0.06, 0.11:0.06), antenna longer than body (3.03, 2.63); antennal scrobes-frons sloped and forming a shelf. Face flat or nearly so, scattered and finely punctate, 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 (0.10, 0.13). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 212A, E, F, I ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout, interspaces smooth. 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 mostly overlapping the MPM; ATS demilune with complete undulate/reticulate carinae; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation nearly at the same level as mesoscutum (flat) and with same kind of sculpture as mesoscutum. Metanotum with BM wider than PFM (clearly differentiated); MPM semicircular without median longitudinal carina; AFM without setiferous lobes and not as well delineated as PFM; PFM thick and smooth; ATM proximally with a groove with some sculpturing and distally smooth. Propodeum without median longitudinal carina, proximal half weakly curved relatively polished and distal half slightly rugose; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle without distal carina; nucha without distinct 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 finely sculptured only ventrally and dorsally without a carina. Metasternum convex. Contour of mesopleuron convex; precoxal groove smooth, shiny and shallow, but visible; epicnemial ridge convex, teardrop-shaped.

Legs ( Fig. 212A, J ). Ventral margin of fore telotarsus entire without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.13, 0.06). Hind coxa with punctation only on ventral surface, dorsal outer depression absent. Inner spur of hind tibia longer than outer spur (0.22, 0.18), 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, 0.12).

Wings ( Fig. 212K ). Fore wing with r vein straight; 2RS vein slightly convex to convex; r and 2RS veins forming a weak, even curve 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 straightened and subproximally evenly convex, and setae evenly scattered in the margin.

Metasoma ( Fig. 212A, G, H, J ). Metasoma laterally compressed. Petiole on T1 finely sculptured distal, but only laterally, evenly narrowing distally (length 0.40, maximum width 0.22, 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 0.18, length T2 0.18), edges of median area polished and lateral grooves deep, median area broader than long (length 0.18, maximum width 0.20, minimum width 0.10); T2 with scattered pubescence only distally. T3 longer than T2 (0.21, 0.18) and with scattered pubescence only distally. Pubescence on hypopygium dense.

Cocoons. Oval cocoons with evenly smooth silk fibers. Cocoons adhered to the larval cuticle.

Male.

Coloration similar to that of females, although on metasoma the T4 and beyond terga are darker that the others and without the medial dark brown area present in females.

Etymology.

Sydney Anne Cameron is interested in social insect behavior, evolution, ecology, and phylogenetic theory of bees. Currently, she is a professor at UIUC, IL, USA.

Distribution.

Parasitized caterpillars were collected in Costa Rica, ACG, Sector Pitilla ( Estación Pitilla, Sendero Carica, and Sendero Orosilito) and Sector Rincón Rain Forest (Sendero Alajuela), during June 2009 and May–June 2011 at 405 m, 660 m, 675 m, and 900 m in rain forest.

Biology.

The lifestyle of this parasitoid species is gregarious. Mesochorus ( Ichneumonidae : Mesochorinae) was reported as hyperparasitoid.

Host.

Pachygonidia drucei (Rothschild & Jordan), Enyo ocypete (L.) and Aleuron carinata (Walker) ( Sphingidae : Macroglossinae) feeding on Doliocarpus multiflorus ( Dilleniaceae ). Caterpillars were collected in first, second, fourth and fifth instar.
