General body coloration satin black except scape yellow-brown; pedicel distal half yellow-brown and proximal half brown; all antennal flagellomeres brown on both sides; labrum and mandible yellow-brown; tegulae light brown; glossa, maxillary and labial palps yellow. Eyes reddish (in preserved specimen) and ocelli silver. Fore and middle legs dark yellow except brown-red/reddish coxae and brown claws; hind legs dark yellow except black coxae, femora distally brown, tibiae 1/3 distal and tarsomeres brown although proximal half of basitarsus yellow. Petiole on T1 brown with some reddish tints, contours darkened and sublateral areas yellow; T2 with median and adjacent areas brown, adjacent area with contours well-defined, both dark areas forming a rectangle-shape area, narrow lateral ends yellow-brown; T3 mostly brown except lateral ends proximally with yellow corners; T4 and beyond brown; distally each tergum with a narrow yellowish translucent band.

Description. <b>Head</b> (Fig. 218 A–D). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.20:0.08, 0.22:0.08, 0.23:0.08), distal antennal flagellomere longer than penultimate (0.15:0.06, 0.11:0.06), antenna longer than body (3.03, 2.83); 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 anteriorly convex and posteriorly straight. POL shorter than OOL (0.11, 0.15). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide. <b>Mesosoma</b> (Fig. 218A, E, F, I). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation proximally distinct, but distally absent/dispersed, interspaces wavy/lacunose. Scutellum triangular, apex sloped and fused with BS, but not in the same plane, scutellar punctation scattered throughout, in profile scutellum slightly convex, but on same plane as mesoscutum, phragma of the scutellum widely visible; BS only very partially overlapping the MPM; ATS demilune with short stubs delineating the area; dorsal ATS groove smooth. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation with a sloped transverse strip, smooth and shiny. Metanotum with BM convex; MPM circular without 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 smooth. Propodeum with a mix of faint rugae and fine sculpture and 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 defined smooth band only proximally; 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 with a carina. Metasternum convex. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep with transverse lineate sculpture; epicnemial ridge widen. <b>Legs</b> (Fig. 218A). Ventral margin of fore telotarsus entire without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.11, 0.08). Hind coxa with punctation only on ventral surface, dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.27, 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 (0.13, 0.14). <b>Wings</b> (Fig. 218K). Fore wing with r vein curved; 2RS vein straight; r and 2RS veins forming a weak, even curve 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 microtrichiae virtually throughout; 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 and complete, but junction with 1-1A vein spectral. Hind wing with vannal lobe wide, subdistally and subproximally straightened, and setae present proximally, but absent distally. <b>Metasoma</b> (Fig. 218A, G, H, J). Metasoma laterally compressed. Petiole on T1 finely sculptured distal, but only laterally, virtually parallel-sided over most of length, but narrowing over distal 1/3 (length 0.39, maximum width 0.20, minimum width 0.07), 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 0.17, length T2 0.17), edges of median area polished and lateral grooves deep, median area broader than long (length 0.17, maximum width 0.23, minimum width 0.09); T2 with scattered pubescence throughout. T3 longer than T2 (0.25, 0.17) and with pubescence more notorious in distal half. Pubescence on hypopygium scattered. <b>Cocoons.</b> Unknown. Comments. In general, the female body is slender and cylindrical. In some females, the coloration on S1-2 is yellow, but the remaining sterna completely brown. In other females, only the three distal sterna (S4-6) are completely brown. The proximal edge of ATS demilune is carinate. Male. The male body is slender and cylindrical like the female. Male is similar in coloration except that the hind femora has two colorations: proximal 3/4 dark brown-red and distal 1/4 brown; the coloration on S1-3 is yellow-brown, but the remaining sterna are completely brown; the external genitalia is small. Etymology. Thomas (Tom) R. Walla is an American entomologist whose speciality is in tropical ecology, tropical butterflies, and patterns of species diversity. He is a professor at Mesa State College, Grand Junction, CO, USA. Distribution. Parasitized caterpillars were collected in Ecuador, Napo, Yanayacu Biological Station (Yanayacu Road), during May 2005 and May 2009 at 2,100 m in cloud forest. Biology. The lifestyle of this parasitoid species is gregarious. Host. Undetermined species of Apatelodidae feeding on <i>Dendrophorbium lloense</i> (Asteraceae). Undetermined species of Erebidae (Arctiinae) feeding on <i>Baccharis latifolia</i> (Asteraceae). Caterpillars were collected in third instar.
