( Fig. 170 A–M View Figure 170 ). General body coloration shiny black except apex of mandibles, labrum, and tegulae light brown-reddish; apex of pedicel light brown; scape and all antennal flagellomeres (on both sides) dark brown/black; glossa, maxillary and labial palps light yellow-brown. Eyes silver and ocelli yellow-brown. Fore and middle legs light yellow-brown and claws brown; hind legs light yellow-brown except black coxae distally brown-reddish, femora distally brown, tibiae completely brown, and tarsomeres brown. Petiole on T1 dark brown/black with contours darkened and sublateral areas light yellow-brown; T2 with median and adjacent areas brown, and lateral ends yellow; T3 and beyond completely brown; distally each tergum with a narrow yellow transparent band. In lateral view, T1-2 completely yellow-brown; T3-4 ventrally yellow, dorsally brown, extent of brown area wider in T4 than T3; T5 and beyond brown. S1 yellow-brown; S3-4 yellow; penultimate sternum and hypopygium brown.
Description.
Head ( Fig. 170 A–D View Figure 170 ). Head triangular with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.23:0.09, 0.25:0.09, 0.25:0.09), distal antennal flagellomere longer than penultimate (0.15:0.06, 0.12:0.06), antenna longer than body (3.78, 2.68); antennal scrobes-frons sloped and forming a shelf. Face with dense fine punctations, distal half dented only laterally, interspaces smooth 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 subequal in length with OOL (0.11, 0.11). Malar suture present. Median area between lateral ocelli without depression. Vertex laterally pointed or nearly so and dorsally wide.
Mesosoma ( Fig. 170A, F, G, J View Figure 170 ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout, interspaces smooth. 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 partially exposed; BS only very partially overlapping the MPM; ATS demilune with short stubs delineating the area; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and homogeneous foveae, area just behind transscutal articulation sloped and with same kind of sculpture as mesoscutum. 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 without median longitudinal carina, proximal half curved with medium-sized sculpture and distal half relatively polished and 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 and dorsal furrow smooth, but ventral furrow with short parallel carinae. Propleuron with fine punctations 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. Ventral margin of fore telotarsus entire without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.12, 0.06). 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 (0.41, 0.31), entire surface of hind tibia with dense strong spines clearly differentiated by color and length.
Wings ( Fig. 170L, M View Figure 170 ). 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 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; 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, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe very narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.
Metasoma ( Fig. 170A, H, I, K View Figure 170 ). Metasoma laterally compressed. Petiole on T1 completely smooth and polished, with faint, satin-like sheen, virtually parallel-sided over most of length with round apex (length 0.39, maximum width 0.19, minimum width 0.13), 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 0.15, length T2 0.15), lateral grooves deep, median area broader than long (length 0.15, maximum width 0.20, minimum width 0.08); T2 with scattered pubescence throughout. T3 longer than T2 (0.23, 0.15) and with scattered pubescence throughout.
Cocoon ( Figs 4D View Figure 4 , 170E View Figure 170 ). White lace-shaped cocoon with evenly smooth silk fibers.
Comments.
The ocelli are very close to each other ( Fig. 170D View Figure 170 , diameter of ocelli 0.06 mm, distance between median ocellus and lateral ocellus 0.03 mm), the margin of median area on T2 curved rather than straight ( Fig. 170H View Figure 170 ), the propodeum proximally is curved and distally drops and looks like a slightly inclined wall ( Fig. 170G View Figure 170 ), the limit between the mesopleuron and the metasternum has a dented area, the hind coxa is stout ( Fig. 170K View Figure 170 ), and the mesosoma is broad and stout ( Fig. 170F, J View Figure 170 ). The holotype has hind tarsomeres missing.
Female.

Etymology.
D. Monty Wood is a Canadian specialist on Tachinidae for which he is the world’s leading expert. He also has contributed to the knowledge of Simuliidae (black flies). He is an honorary research associate at Canadian National Collection ( CNC) of Insect, Arachnids and Nematodes, Ottawa, Ontario, Canada. Monty divides his time between the CNC and Instituto Nacional de Biodiversidad ( INBio), Santo Domingo de Heredia, Costa Rica .
Distribution.
Parasitized caterpillar was collected in Ecuador Napo, Yanayacu Biological Station (Sendero Macuculoma), during October 2007 at 2,091 m in cloud forest.
Biology.
The lifestyle of this parasitoid species is solitary.
Host.
Undetermined species of Erebidae ( Arctiinae) feeding on Chusquea scandens ( Poaceae ). Caterpillar was collected in second instar.
