Scutellum triangular, apex sloped and fused with BS, scutellar punctation distinct 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 short stubs delineating the area; dorsal ATS groove smooth. 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 and bisected by a 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 relatively polished without median longitudinal carina, proximal half curved; distal edge of propodeum without flange; 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 with fine rugae and dorsally wit h a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep with faintly transverse lineate sculpture; epicnemial ridge convex, teardrop-shaped.

Legs. Ventral margin of fore telotarsus entire, but with a tiny curved seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.20, 0.06). Hind coxa with punctation only on ventral surface and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.25, 0.16), entire surface of hind tibia with dense strong spines clearly differentiated by color and length.

Comments.

In some specimens, the general body coloration is polished and black instead of light brown and in lateral view the T3 is brown only ventrally.

Male

( Fig. 100 A–IView Figure 100). Similar in coloration and shape to female.

Etymology.

Henry Keith Townes Jr. (20 January 1913 - 2 May 1990) was widely known for his work on hymenopteran systematics, particularly the large and difficult family Ichneumonidae  .

Distribution.

Parasitized caterpillars were collected in Costa Rica, ACG, Sector Cacao (Sendero Nayo and Sendero Toma Agua), Sector Del Oro ( Metereológico), Sector Mundo Nuevo (Sendero Melón), and Sector Pitilla (Sendero Evangelista), during February and August 1998, September 2002;, April 2003, June 2007, and January and October 2010 at 361 m, 590 m, 660 m, 1,090 m, and 1,140 m in intergrade dry-rain, rain and cloud forests. The adult parasitoid was collected in Costa Rica, ACG, Sector San Cristóbal (Bosque Trampa Malaise), during July 2007 at 815 m in rain forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Heterochroma sarepta  (Druce) ( Noctuidae  : Amphipyrinae  ) ( Fig. 4SView Figure 4) feeding on Smilax mollis  and S. spinosa  ( Smilacaceae  ). Caterpillars were collected in second, third, fourth and fifth instar.
