Eyes black and ocelli silver/reddish (in preserved specimen). Fore and middle legs yellow except coxae brown with inner side almost completely yellow, and claws brown; hind legs yellow except black coxae, femora with apex brown, distal 1/3 of tibiae brown, and tarsomeres brown although proximally basitarsus with a narrow yellow band. Petiole on T1 dark brown and sublateral areas yellow-brown; T2 with median area brown, and adjacent area and lateral ends yellow-brown; T3 broadly brown with a small yellow-brown area on the corner proximal; T4 and beyond completely brown; distally each tergum with a narrow whitish transparent band.

Description.

Head ( Fig. 166 A–C ). Head rectangle with pubescence long and dense. Proximal three antennal flagellomeres length longer than wide (0.16:0.05, 0.18:0.05, 0.17:0.05), distal antennal flagellomere longer than penultimate (0.11:0.05, 0.08:0.05), antenna longer than body (2.12, 2.02); antennal scrobes-frons sloped and forming a shelf. Face flat or nearly so, punctate-lacunose, interspaces wavy and longitudinal median carina present. Frons smooth. Temple wide, punctate-lacunose and interspaces wavy. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye with both sides convex. POL shorter than OOL (0.09, 0.11). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 166A, D, E, G ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct proximally with polished area distally, interspaces smooth. 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 partially exposed; BS only very partially overlapping the MPM; ATS demilune with a little, complete and parallel carinae; dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation with small and heterogeneous 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, smooth and with lateral ends rounded; ATM proximally with a groove with some sculpturing and distally with rugae. Propodeum without median longitudinal carina and with indistinct sculpture, proximal half weakly curved 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 and parallel carinae. Propleuron with fine punctations throughout and dorsally without a carina. Metasternum convex. Contour of mesopleuron straight/angulate or nearly so; precoxal groove smooth, shiny and distinct; 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). Hind coxa with punctation only on ventral surface, dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.18, 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 (0.11, 0.11).

Wings ( Fig. 166J, K ). 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 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 and complete, but junction with 1-1A vein spectral. Hind wing with vannal lobe very narrow, subdistally evenly convex and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 166A, F, H, I ). Metasoma laterally compressed. Petiole on T1 completely smooth and polished, with faint, satin-like sheen, evenly narrowing distally (length 0.27, maximum width 0.13, minimum width 0.09) 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 0.11, length T2 0.11), edges of median area polished and lateral grooves deep, median area broader than long (length 0.11, maximum width 0.13, minimum width 0.07); T2 with scattered pubescence only distally. T3 longer than T2 (0.16, 0.11) and with scattered pubescence throughout. Pubescence on hypopygium scattered.

Cocoons. Light brown oval cocoons with evenly smooth silk fibers. Cocoons adhered among the setae of the caterpillar

Comments.

The ovipositor sheath is long as in Sathon , the pubescence is distributed along the surface, but not concentrated at the apex ( Fig. 166A, H ).

Male

( Fig. 167 A–G ). Similar in coloration and shape to female.

Etymology.

Michael (Mike) E. Schauff’s research has focused upon the biology and systematics of chalcidoid wasps, including Eulophidae . He has been based at the USDA Systematic Entomology Laboratory at the American National Museum of Natural History, New York, NY, USA.

Distribution.

The parasitized caterpillars were collected in Costa Rica, ACG, Sector San Cristóbal (Puente Palma and Vado Río Cucaracho), during June 2006 and September 2008 at 460 and 640 m in rain forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Bertholdia albipuncta Schaus ( Erebidae : Arctiinae) feeding on Drymonia macrophylla ( Gesneriaceae ) and B. specularis ( Herrich-Schäffer) ( Erebidae : Arctiinae) feeding on Sabicea villosa ( Rubiaceae ). Caterpillars were collected in fourth instar.
