Mesosoma ( Fig. 86 A–C, E View Figure 86 ). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation distinct throughout, interspaces with microsculpture. Scutellum triangular, apex sloped and fused with BS, scutellar punctation scattered 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 short stubs delineating the area and inner side with a row of foveae; dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation smooth, shiny and depressed centrally. 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 and smooth; ATM proximally with semircular/undulate carina and distally smooth.

Hind coxa with punctation only on ventral surface and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.23, 0.15), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.10, 0.10).
Wings ( Fig. 86I, J View Figure 86 ). 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.

Metasoma ( Fig. 86A, D, F–H View Figure 86 ). 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 View Figure 4 ). 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.
This species looks like Distatrix , the lateral grooves delimiting the median area on T2 are far from the proximal edge of T3.
( Fig. 87 A–J View Figure 87 ). The body coloration and the body shape similar to female.
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 .
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.
The lifestyle of this parasitoid species is gregarious.
Nystalea collaris Schaus ( Fig. 4P View Figure 4 ) ( 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.
