( Fig. 88A ). General body coloration dark brown except labrum, mandibles, scape, and pedicel yellow-brown; glossa, maxillary and labial palps, and tegulae yellow; three most proximal antennal flagellomeres dorsally lighter (light brown) than ventrally (dark brown), following flagellomeres dark brown on both sides. Eyes gray/black and ocelli reddish. Fore and middle legs yellow except brown coxae (inner side yellow-brown) and fore claws brown; hind legs yellow-brown except coxae and distal 3/4 of tibiae brown, and tarsomeres brown except proximal 1/3 of basitarsus yellow-brown. Petiole on T1 brown, contour darkened and sublateral areas yellow; T2 with median area dark, adjacent area and lateral ends yellow; T3 medially with a inverted triangular brown area and remaining area yellow-brown; T4 and beyond brown; distally each tergum with a narrow whitish transparent band. In lateral view, T1-2 completely yellow; T3 yellow, dorsally brown; T4 and beyond completely brown. S1-4 completely yellow; penultimate sternum and hypopygium brown, medially yellow.

Description.

Head ( Fig. 88A, B, E ). Head triangular with pubescence short and dense. Proximal three antennal flagellomeres longer than wide (0.22:0.06, 0.20:0.06, 0.18:0.06), distal antennal flagellomere longer than penultimate (0.11:0.05, 0.09:0.05), antenna longer than body (2.63, 2.53); antennal scrobes-frons shallow. Face convex, with dense fine punctations, interspaces smooth and longitudinal median carina present. Frons smooth. Temple wide, punctate and interspaces wavy. Inner margin of eyes straight throughout; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.09, 0.11). Malar suture absent or difficult to see. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 88 A–C, E ). Mesosoma dorsoventrally convex. Mesoscutum with narrow grooves laterally, punctation distinct throughout, interspaces with microsculpture. 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 completely concealed; BS only very partially overlapping the MPM; ATS demilune with complete undulate/reticulate carinae; dorsal ATS groove smooth. Transscutal articulation with small and heterogeneous 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 lateral ends rounded; ATM proximally with a well-defined row of foveae and distally smooth. Propodeum without median longitudinal carina, proximal half curved with medium-sized sculpture and distal half relatively polished; distal edge of propodeum without flange; 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 furrows dorsal and ventral with short parallel carinae. Propleuron with fine rugae and dorsally with a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep with faintly lineate sculpture; epicnemial ridge convex, teardrop-shaped.

Legs. Ventral margin of fore telotarsus entire, but with a tiny curved seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.12, 0.07). Hind coxa with punctation only on ventral surface and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.20, 015), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.15, 0.10).

Wings ( Fig. 88I, J ). Fore wing with r vein slightly 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 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 a small smooth area; vein 2CUa absent and vein 2CUb spectral; vein 2 cu-a absent; vein 2-1A absent; tubular vein 1 cu-a straight, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe wide, subdistally straightened, subproximally straightened, and setae present only proximally.

Metasoma ( Fig. 88A, 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 (length 0.32, maximum width 0.17, minimum width 0.09), and with scattered pubescence concentrated in the first distal third. Lateral grooves delimiting the median area on T2 distally losing definition (length median area 0.11, length T2 0.14), edges of median area polished and lateral grooves deep, median area broader than long (length 0.11, maximum width 0.20, minimum width 0.08); T2 with scattered pubescence only distally. T3 longer than T2 (0.21, 0.14) and with scattered pubescence only distally. Pubescence on hypopygium dense.

Cocoons. White oval cocoons with evenly smooth silk fibers. Cocoons arranged in two rows of cordwood stack on each side of caterpillar and adhered to the leaf substrate.

Comments.

This species shares a character with Distatrix , that the lateral grooves delimiting the median area on T2 do not reach the proximal part of T3.

Male

( Fig. 89 A–J ). Similar in coloration and shape to female.

Etymology.

Gavin R. Broad is Senior Curator in the Entomology Department at the Natural History Museum, London, UK, and an expert on Ichneumonoidea and Vespoidea (except ants).

Distribution.

Parasitized caterpillar was collected in Costa Rica, ACG, Sector Santa Rosa ( Área administrativa), during September 1995 at 295 m in dry forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Pararcte schneideriana Stoll ( Noctuidae : Catocalinae) feeding on Cecropia peltata ( Urticaceae ). Caterpillar was collected in fifth instar.
