Description.

Head ( Fig. 127A, B, E ). Head triangular with short and dense pubescence. Proximal three antennal flagellomeres longer than wide (0.17:0.06, 0.16:0.06, 0.17:0.06), distal antennal flagellomere longer than penultimate (0.10:0.06, 0.08:0.06), antenna longer than body (2.30, 2.27); antennal scrobes-frons shallow. Face flat or nearly so, with dense and fine punctations, interspaces wavy 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, 0.13). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 127 A–C, E ). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation distinct throughout, interspaces wavy/lacunose. 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 and incomplete parallel carinae only proximally; dorsal ATS groove smooth. Transscutal articulation with small and homogeneous 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 a distal flat flange; ATM proximally with a groove with some sculpturing and distally smooth. Propodeum relatively polished without median longitudinal carina, 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 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, smooth and shiny; 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 as equal in length as fourth tarsomere (0.10, 0.09). Hind coxa with punctation only on ventral surface and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.21, 0.16), 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, 0.11).

Wings ( Fig. 127I, J ). Fore wing with r vein slightly curved; 2RS vein slightly convex to convex; 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; 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 and complete, but junction with 1-1A vein spectral. Hind wing with vannal lobe narrow, subdistally evenly convex and subproximally straightened, and setae present only proximally.

Metasoma ( Fig. 127A, D, F–H ). Metasoma laterally compressed. Petiole on T1 completely smooth and polished, with faint and satin-like sheen, virtually parallel-sided over most of length, but narrowing over distal 1/3 (length 0.30, maximum width 0.13, 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 0.10, length T2 0.12), edges of median area polished and lateral grooves deep, median area broader than long (length 0.10, maximum width 0.15, minimum width 0.07); T2 with scattered pubescence only distally. T3 longer than T2 (0.23, 0.12) and with scattered pubescence throughout. Pubescence on hypopygium dense.

Cocoons. Light brown or beige oval cocoons with evenly smooth silk fibers. Two rows of brown cordwood cocoons with no space for the caterpillar between them and adhered to the leaf substrate.

Male

( Fig. 128 A–J ). Similar in coloration and shape to female.

Etymology.

John M. Heraty is a professor at the University of California, Riverside ( UCR), CA, USA. His research is focused on the systematics, phylogeny, and biogeography of the Chalcidoidea ( Hymenoptera ).

Distribution.

Parasitized caterpillars were collected in Costa Rica, ACG, Sector San Cristóbal (Cementerio Viejo), during November 2003 at 570 m in rain forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Scaptius vinasia (Schaus) ( Erebidae : Arctiinae) feeding on Eugenia basilaris ( Myrtaceae ). Caterpillars were collected in forth instar.
