Coloration

( Fig. 68A View Figure 68 ). General body coloration black except first four proximal antennal flagellomeres dorsally lighter (yellow-brown) than ventrally (brown), remaining flagellomeres brown on both sides; scape, labrum, mandibles, and tegulae yellow-brown; pedicel with some brown hue; maxillary and labial palps yellow. Eyes gray and ocelli silver. Fore and middle legs yellow except dark brown coxae and brown claws; hind legs yellow except black coxae, distal dot in femora, distal half tibiae, distal 3/4 of basitarsus and rest of tarsomeres brown. Petiole on T1 with two colorations: proximal 3/4 yellow and distal 1/4 black, contours darkened, and sublateral areas yellow; T2 with median and adjacent areas black, adjacent area wide with limits well-defined and forming together with the median area a rectangle shape, and lateral ends yellow/yellow-brown; T3 medially with a black area which width coincides with the distal width of median plus adjacent areas on T2, black area on T3 reaches the distal edge of T3, and lateral ends yellow; T4 and beyond black; distally each tergum with a narrow whitish transparent band. In lateral view, T1-3 completely yellow; T4 and beyond completely brown/black. S1-3 yellow; S4 proximal half yellow, distal half brown/black; penultimate sternum and hypopygium completely brown/black.

Description.

Head ( Fig. 68A, B, E View Figure 68 ) Head rounded with pubescence long and dense. Proximal three antennal flagellomeres length longer than wide (0.19:0.05, 0.17:0.05, 0.17:0.05), distal antennal flagellomere longer than penultimate (0.11:0.05, 0.08:0.05), antenna longer than body (2.12, 2.07); antennal scrobes-frons shallow. Face with dense fine punctations, laterally with depressions, interspaces wavy and longitudinal median carina present. Frons punctate. Temple wide, punctate and interspaces wavy. 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 rounded and dorsally wide.

Mesosoma ( Fig. 68 A–C, E View Figure 68 ). Mesosoma dorsoventrally convex. Mesoscutum shape proximally convex distally flat, punctation distinct proximally, but absent/dispersed distally and interspaces wavy/lacunose. Scutellum triangular, apex sloped and fused with BS, scutellar punctation distinct peripherally, absent centrally, in profile scutellum flat and on same plane as mesoscutum, phragma of the scutellum widely visible; BS only very partially overlapping the MPM; ATS demilune with short stubs delineating the area; 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 with a small lobe and not as well delineated as PFM; PFM thick, smooth and with lateral ends rounded; ATM with complete parallel carinae. Propodeum without median longitudinal carina, proximal half weakly curved relatively polished and distal half with a shallow dent at each side of nucha; 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 fine punctations throughout and dorsally without a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so, precoxal groove deep with faintly transverse lineate sculpture; epicnemial ridge elongated more fusiform (tapering at both ends).

Legs. Ventral margin of fore telotarsus excavated with conspicuous curved seta over this excavation, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.12, 0.06). Hind coxa with punctation only on ventral surface and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.25, 0.14), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.09, 0.09).

Wings ( Fig. 68I, J View Figure 68 ). 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; 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, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe narrow, subdistally straightened, subproximally straightened, and setae present only proximally.

Metasoma ( Fig. 68A, D, F–H View Figure 68 ). 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 0.31, maximum width 0.14, minimum width 0.06), with little 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 0.14), edges of median area polished and lateral grooves deep, median area broader than long length (length 0.10, maximum width 0.18, minimum width 0.06); T2 with a distinctive row of pubescence only at the distal margin. T3 longer than T2 (0.18, 0.14) and with scattered pubescence throughout. Pubescence on hypopygium dense.

Cocoons. Brown or gray oval cocoons with evenly smooth silk fibers. A single row of cordwood cocoons on each side of caterpillar.

Comments.

Medially, the pronotum is at a different level to the remaining portion of the structure. The propodeal spiracle is small.

Male

( Fig. 69 A–I View Figure 69 ). Similar in shape to female, but the general coloration is lighter than female.

Etymology.

David B. Wahl works at the American Entomological Institute ( AEI) that is part of Utah State University ( USU), Logan, UT, USA. His main focus has been the family Ichneumonidae .

Distribution.

Parasitized caterpillar was collected in Costa Rica, ACG, Sector Santa Rosa (Cafetal), during August 1992 at 280 m on coffee plantation.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Parachabora abydas ( Herrich-Schäffer) ( Noctuidae : Catocalinae) feeding on Tephrosia multifolia ( Fabaceae). Caterpillar was collected in fifth instar.
