General body coloration shiny, satin black except pedicel yellow-brown; scape yellow-brown distally with a ring brown; three-four most proximal antennal flagellomeres dorsally lighter (light brown) than ventrally (dark brown), remaining flagellomeres dark brown on both sides; labrum, mandible, glossa, and tegulae yellow-brown; maxillary and labial palps ivory/pale yellow.

In lateral view, T1-3 yellow-brown; T4 yellow, but dorsally brown; T5 and beyond brown. S1-3 yellow-brown; S4 proximal half yellow, distal half brown; penultimate sternum and hypopygium brown.


Head ( Fig. 191 A–D View Figure 191 ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.19:0.05, 0.19:0.05, 0.19:0.05), distal antennal flagellomere longer than penultimate (0.11:0.05, 0.09:0.05), antenna longer than body (2.53, 2.32); antennal scrobes-frons shallow. Face with slightly rugose sculpture, with depression only laterally, 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 anteriorly convex and posteriorly straight. POL shorter than OOL (0.09, 013). Malar suture absent or difficult to see. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 191A, F, G, J View Figure 191 ). 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 convex and slightly higher than mesoscutum, phragma of the scutellum partially exposed; BS mostly overlapping the MPM; ATS demilune with short stubs delineating the area; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation sloped, smooth and shiny. Metanotum with BM wider than PFM (clearly differentiated); MPM circular with some sculpture inside; AFM without setiferous lobes and not as well delineated as PFM; PFM thick, smooth and with lateral ends rounded; ATM proximally with a well-defined row of foveae and distally smooth. Propodeum relatively polished without median longitudinal carina, proximal half curved; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle distally framed by faintly concave/wavy 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 a mix of rugae and fine punctation, dorsally without a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep and with faintly lineate sculpture; epicnemial ridge convex, teardrop-shaped.

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 (0.13, 0.07). Hind coxa with dorsal half sparsely punctate, ventral half densely punctate, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.25, 0.20), 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, 0.10).

Wings ( Fig. 191L View Figure 191 ). Fore wing with r vein slightly curved; 2RS vein straight; r and 2RS veins forming an angle at their junction and outer side of junction forming a slight 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 present only proximally as tubular vein; 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 proximally, but absent distally.

Metasoma ( Fig. 191A, H, I, K View Figure 191 ). Metasoma curved. Petiole on T1 completely smooth and polished, with faint, satin-like sheen, parallel-sided in proximal half and then narrowing (length 0.32, maximum width 0.17, minimum width 0.08), and with scattered pubescence concentrated in the first distal third. Lateral grooves delimiting the median area on T2 distally losing definition (length median area 0.11, length T2 0.14), edges of median area polished and lateral grooves deep, median area broader than long (length 0.11, maximum width 0.27, minimum width 0.06); T2 with scattered pubescence only distally. T3 longer than T2 (0.21, 0.14) and with scattered pubescence throughout. Pubescence on hypopygium scattered.

Cocoons. Light brown oval cocoons with silk fibers ordered, but covered by a net. Cordwood cocoons adhered to the leaf substrate.


The body is elongated, cylindrical , and curved ( Fig. 191A View Figure 191 ).


( Fig. 192 A–J View Figure 192 ). The body shape is similar to female.


Robbin W. Thorp is a professor emeritus at the University of California, Davis ( UC), CA, USA. His research has been focused on bee biology: pollination ecology, foraging behavior, management of bee populations, and the systematics and ecology of bees.


The parasitized caterpillars were collected in Costa Rica, ACG, Sector San Cristóbal (Finca San Gabriel and Sendero Huerta), during September–October 2007 at 527m and 645 m in rain forest.


The lifestyle of this parasitoid species is gregarious.


Letis mycerina (Cramer) ( Erebidae : Erebiinae) feeding on Inga oerstediana and I. punctata ( Fabaceae ). Caterpillars were collected in third and fifth instar.
