Fore and middle legs yellow, but claws brown; hind legs yellow except black-brown coxae with yellow apex, distally femora with a brown dot, apex of the tibiae and tarsomeres brown. Petiole on T1 yellow, but distal 1/3 brown, contours brown, and sublateral areas light yellow; median area on T2 with proximal half yellow-brown and distal half brown, and lateral ends light yellow; T3 medially with an extended brown area with a central yellow-brown spot, and lateral ends yellow; T4 and beyond completely brown-black; distally each tergum with a narrow yellowish transparent band. In lateral view, T1-3 completely yellow; T4 and beyond brown. S1-4 yellow; penultimate sternum yellow-brown; hypopygium completely brown.

Description.

Head ( Fig. 48A ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.21:007, 0.21:007, 0.21:0.07), distal antennal flagellomere longer than penultimate (0.11:0.05, 0.09:0.05), antenna longer than body (2.58, 2.12); antennal scrobes-frons shallow. Face convex with scattered finely punctate, interspaces with microsculpture and longitudinal median carina present. Frons punctate. Temple wide with punctate sculpture and interspaces with microsculpture. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.09, 0.11). Malar suture present. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 48 A–C, E ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct proximally ranging to satiny 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 completely concealed; BS only very partially overlapping the MPM; ATS demilune with complete undulate/reticulate carinae; dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation with small and homogeneous foveae, area just behind transscutal articulation smooth, shiny and nearly at the same level as mesoscutum (flat). Metanotum with BM wider than PFM (clearly differentiated); MPM circular and bisected by a median longitudinal carina; AFM without setiferous lobes and not as well delineated as PFM; PFM thick and smooth; ATM with little and incomplete parallel carinae proximally. Propodeum without median longitudinal carina, proximal half weakly curved with rather coarse sculpture and distal half rugose with a shallow dent at each side of nucha; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle distally framed by a short concave 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 rugae and dorsally without a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove shallow, but visible and with transverse 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, 0.06). Hind coxa with punctation only on ventral surface and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.24, 0.19), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.13, 0.10).

Wings ( Fig. 48G, H ). Fore wing with r vein curved; 2RS vein straight; r and 2RS veins forming an angle 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 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 and subproximally straightened, and setae present only proximally.

Metasoma ( Fig. 48A, D, F, I, J ). 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 0.34, maximum width 0.14, minimum width 0.09), petiole 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 0.14), edges of median area polished and lateral grooves deep, median area broader than long (length 0.10, maximum width 0.12, minimum width 0.05), 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. Black oval cocoons with silk fibers evenly smooth. Single row of cordwood cocoons forming a long chain of irregularly cocoons alongside the caterpillar cadaver and adhered to the leaf substrate.

Comments.

The propodeum in both sexes is rugose.

Male

( Fig. 49 A–J ). The males are slenderer than females. The hind coxa is completely brown.

Etymology.

Charles Duncan Michener (22 September 1918 - 1 November 2015) was an American entomologist who devoted his entire distinguished career to the systematics and natural history of bees.

Distribution.

The parasitized caterpillar was collected in Costa Rica, ACG, Sector Rincón Rain Forest (Sendero Albergue Crater) and Sector San Cristóbal (Melina Bufalo), during March 2001 at 560 m and 980 m in rain forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Phyprosopus parthenope Schaus ( Noctuidae , Catocalinae) on Celtis iguanaea ( Ulmaceae ). Caterpillar was collected in fifth instar.
