General body coloration brown-red/reddish except labrum and maxillae yellow-brown; glossa, maxillary and labial palps yellow; propleuron, pronotum, epicnemial ridge, ventral edge of mesopleuron, distal edge of mesoscutum, lunules, BS, PFM, BM, and proximal-medial part of propodeum with yellow-brown tints. Eyes and median ocellus silver, lateral ocelli brown. Fore and middle legs yellow although middle tarsomeres with brown tints; hind legs yellow except coxae completely brown-red/reddish, distally femora with a tiny dot, tibiae and tarsi brown. Petiole on T1 brown-red/reddish coloration intensifying at the edges, thus contours darkened, sublateral areas light yellow-brown; T2 with median and adjacent areas brown, and lateral ends yellow-brown; T3 extended brown coloration, but lateral areas yellow-brown; T4 and beyond completely brown and distally each tergum with a narrow whitish translucent band. In lateral view, T1-3 completely yellow, T4 and beyond dorsally brown and ventrally yellow, extent of brown coloration intensity increasing from proximal to distal. S1-3 completely yellow; S4 yellow, but medially brown; penultimate sternum and hypopygium brown.
Head ( Fig. 10B, C View Figure 10 ). Head triangular with long and dense pubescence. Proximal three antennal flagellomeres longer than wide (0.27:0.08, 0.25:0.08, 0.25:0.08); distal antennal flagellomere longer than penultimate (0.15:0.05, 0.11:0.06); antenna shorter than body (3.33, 3.81); antennal scrobes-frons shallow. Face with scattered and finely punctate, interspaces smooth, distal half dented, but only laterally and longitudinal median carina absent. Frons smooth. Temple wide, punctate and interspaces clearly smooth. Inner margin of eyes straight throughout; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL length (0.07, 0.13). Malar suture present. Median area between lateral ocelli without depression. Vertex laterally pointed or nearly so and dorsally wide.
Mesosoma ( Fig. 10D, H View Figure 10 ). Mesosoma dorsoventrally convex. Mesoscutum with narrow grooves laterally, punctation distinct throughout and interspaces smooth. Scutellum triangular with punctation distinct throughout, apex sloped and fused with BS; in profile scutellum convex and slightly higher than mesoscutum; phragma of the scutellum partially exposed; BS only very partially overlapping the MPM; ATS demilune proximally with undulate carinae and distally smooth; 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 without median longitudinal carina; AFM without setiferous lobes and not as well delineated as PFM; PFM thick and smooth; ATM proximally with semircular/undulate carina and distally smooth. Propodeum without median longitudinal carina, entirely with fine sculpture, proximal half of propodeum 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 parallel carinae. Propleuron finely sculpture throughout and dorsally without a carina. Metasternum flat or nearly so. Contour of mesopleuron convex; precoxal groove smooth, shiny and shallow, but visible; epicnemial ridge convex, teardrop-shaped.
Legs ( Fig. 10A, F View Figure 10 ). Fore telotarsus proximally narrow and distally wide and longer than fourth tarsomere (0.10, 0.05). Hind coxa finely punctate throughout, and dorsal outer depression absent. Inner spur of hind tibia longer then outer spur (0.26, 0.21); entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus shorter than fourth tarsomere (0.12, 0.15).
Wings ( Fig. 10J, K View Figure 10 ). Fore wing with r vein slightly curved; 2RS vein slightly convex to convex; r and 2RS veins forming a weak, even curve at their junction and outer side of junction forming a slight stub; shape of 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 with 1/3 proximal lacking microtrichiae; subbasal cell with microtrichiae virtually throughout; 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 straight, incomplete/broken, not reaching the edge of 1-1A vein. Hind wing with vannal lobe narrow, subdistally evenly convex, subproximally straightened, and setae evenly scattered in the margin.
Metasoma ( Fig. 10E, G, I View Figure 10 ). Metasoma laterally compressed. Petiole on T1 finely sculptured only laterally, virtually parallel-sided over most of length, but narrowing over distal 1/3, apex truncate (length 0.45, maximum width 0.26, minimum width 0.11), and with scattered pubescence on distal half, but only laterally. Lateral grooves delimiting the median area on T2 distally losing definition (length median area 0.15, length T2 0.22), edges of median area obscured by weak longitudinal stripes, median area broader than long (length 0.15, maximum width 0.20, minimum width 0.10); T2 with scarce pubescence throughout. T3 slightly longer than T2 (0.24, 022) and with scattered pubescence throughout. Pubescence on hypopygium scattered.
Cocoons ( Fig. 4G View Figure 4 ). White oval cocoons with silk fibers messy/disordered/fluffy. Mass of elongate fluffy, white cocoons somewhat separate and completely filling the caterpillar cocoon.
In both sexes, laterally the mesoscutum with a narrow dent extending throughout almost all of its length ( Fig. 10D, H View Figure 10 ). In some females, the body coloration is brown, thus the tints in the body are brown-red/reddish.
( Fig. 11 A–K View Figure 11 ). Similar in coloration to female.
Álvaro Wille Trejos (May 17, 1928 - June 11, 2006) was a well-known Costa Rican entomologist. Most of his publications were on bees, especially the phylogeny, behavior, and systematics of stingless bees ( Meliponini ).
The parasitized caterpillars were collected in Costa Rica, ACG, Sector Cacao (Sendero Circular, Sendero Derrumbe , and Sendero Maritza), during May 2000, April-May and July 2002, and February 2008 at 760 m, 1,185 m, and 1,220 m in cloud forest.
The lifestyle of this parasitoid species is gregarious.
