Eyes silver and ocelli reddish (in preserved specimen). Fore and middle legs yellow except brown claws; hind legs yellow except light brown coxae (brown coloration is more extensive on the inner side), distal brown spot on the femora, both ends of tibia and tarsomeres brown, although proximally basitarsus with a small yellow band. Petiole on T1 dark brown and sublateral areas yellow; T2 with median area brown, adjacent area yellow-brown which boundaries with lateral ends are blurred, and yellow lateral ends with two elongate brown spots each one at distal corners; T3 almost completely brown, but proximally with a tiny yellow area; T4 and beyond completely brown; distally each tergum with a narrow yellowish transparent band. In lateral view, T1-2 completely yellow; T3 proximal half yellow, distal half brown; T4 and beyond completely brown. S1-3 yellow; S4 and beyond light brown/brown.

Description.

Head ( Fig. 142A, B, E View Figure 142 ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.20:0.06, 0.29:0.06, 0.19:0.06), distal antennal flagellomere longer than penultimate (0.13:0.05, 0.10:0.05), antenna longer than body (2.53, 2.07); antennal scrobes-frons shallow. Face dense fine punctations, interspaces smooth, depression only laterally, and longitudinal median carina present. Frons smooth. Temple wide, punctate and interspaces clearly smooth. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.08, 0.13). Malar suture present. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 142 A–C, E View Figure 142 ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout, interspaces wavy/lacunose. 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 quite a little complete parallel carinae; dorsal ATS groove with carinae only proximally. 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 and bisected by a median longitudinal carina; AFM with a small lobe and not as well delineated as PFM; PFM thick and smooth; ATM proximally with a groove with some sculpturing and distally smooth. Propodeum without median longitudinal carina, proximal half straight or nearly so with medium-sized sculpture and distal half relatively polished; 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, smooth and shiny; epicnemial ridge elongated more fusiform (tapering at both ends).

Legs. Ventral margin of fore telotarsus entire without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.11, 0.06). Dorsal half of hind coxa with scattered punctation and ventral half with dense punctation, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.21, 0.16). 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, 0.09).

Wings ( Fig. 142J, K View Figure 142 ). Fore wing with r vein straight; 2RS vein straight; r and 2RS veins forming an angle at their junction and outer side of junction forming a slight 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 absent; vein 2-1A proximally tubular and distally spectral, although sometimes difficult to see; tubular vein 1 cu-a curved and complete, but junction with 1-1A vein spectral. Hind wing with vannal lobe very narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 142A, D, F–I View Figure 142 ). Metasoma laterally compressed. Petiole on T1 finely sculptured only distally, evenly narrowing distally (length 0.31, maximum width 0.15, minimum width 0.08) and with scattered pubescence concentrated in the first distal third. Lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 (length median area 0.14, length T2 0.14), edges of median area obscured by weak longitudinal stripes, median area broader than long (length 0.14, maximum width 0.17, minimum width 0.07); T2 with scattered pubescence only distally. T3 longer than T2 (0.20, 0.14) and with scattered pubescence only distally. Pubescence on hypopygium dense.

Cocoons. White bud-like cocoon with body ridge-shaped and evenly smooth silk fibers. Cocoons lightly adhered to each other and adhered to the larval cuticle, in litter or soil.

Comments.

The coloration of the adjacent area on T2 is lighter. In some females, the sterna coloration differs a little: S1 yellow, but medially is brown, S4 proximal half yellow and distal half brown.

Male

( Fig. 143 A–L View Figure 143 ). Similar coloration and shape to females.

Etymology.

Lubomir (Lubo) Masner is a Czech-born entomologist. He is the world specialist in the systematics of proctotrupoid parasitioid wasps. Currently, he is an honorary research associate at Agriculture and Agri-Food Canada, Ottawa, Ontario, Canada.

Distribution.

The parasitized caterpillars were collected in Costa Rica, ACG, Sector Pitilla ( Pasmompa and Sendero Memos) and Sector San Cristóbal (Tajo Ángeles), during April 2005, March 2007, and March 2011 at 440 m, 540 m, and 740 m in rain forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Ithomia hippocrenis Bates ( Nymphalidae : Ithomiinae) feeding on Witheringia solanacea ( Solanaceae) and Mechanitis isthmia ( Nymphalidae : Ithomiinae) feeding on Solanum hayesii ( Solanaceae). Caterpillars were collected in second and third instar.
