Fore wing with r vein curved, 2RS vein straight; r and 2RS veins forming a weak, even curve at their junction and outer side of junction not forming a stub; 2M vein straight; 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, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe wide, subdistally straightened and subproximally straightened, and setae present proximally, but absent distally. Metasoma (Fig. 86A, D, F–H). Metasoma laterally compressed. Petiole on T1 completely smooth and polished, with faint, satin-like sheen, virtually parallel-sided over most of length, but narrowing over distal 1/3, apex truncate (length 0.32, maximum width 0.19, minimum width 0.11), and with scattered pubescence concentrated in the first distal third. Lateral grooves delimiting the median area on T2 distally losing definition (length median area 0.09, length T2 0.14), edges of median area polished and lateral grooves deep, median area broader than long (length 0.09, maximum width 0.20, minimum width 0.04); T2 with scattered pubescence only distally. T3 longer than T2 (0.20, 0.14) and with scattered pubescence throughout. Pubescence on hypopygium dense. Cocoons (Fig. 4P). Light brown or gray oval cocoons with ordered silk fibers, but covered by a net. Cocoons on back of caterpillar or attached to the leaf substrate. Comments. This species looks like Distatrix, the lateral grooves delimiting the median area on T2 are far from the proximal edge of T3. Male (Fig. 87 A–J). The body coloration and the body shape similar to female. Etymology. Gary A. P. Gibson is a research scientist at Agriculture and Agri-Food Canada, Ottawa, Ontario, Canada. His expertise is focused upon systematics of chalcid parasitoid wasps (Chalcidoidea), especially the families Eupelmidae and Pteromalidae and functional and comparative morphology of Chalcidoidea and Hymenoptera. Distribution. Parasitized caterpillars were collected in Costa Rica, ACG, Sector El Hacha (Sendero Bejuquilla) and Sector Santa Rosa (Área Administrativa and Cafetal), during July of 1982, 1991, and 1998 at 280 m and 295 m in coffee plantations, dry forest, and intergrade dry-rain forest. Biology. The lifestyle of this parasitoid species is gregarious. Host. Nystalea collaris Schaus (Fig. 4P) (Noctuidae: Nystaleinae) feeding on Psidium guineense and Eugenia salamensis (Myrtaceae) and N. guzmani Schaus feeding on Calyptranthes chytraculia (Myrtaceae). Caterpillar were collected in fourth instar and cocoons were already out of the caterpillar.
