General body coloration black except labrum, mandibles, scape and pedicel yellow-brown; all antennal flagellomeres brown on both sides; glossa, maxillary and labial palps, and tegulae yellow. Eyes and ocelli silver. Fore and middle legs yellow except brown claws; hind legs yellow except black-brown coxae with apex yellow, femora with a tiny brown area on the apex, tibiae with 1/4 distal brown, and tarsomeres brown. Petiole on T1 black and sublateral areas yellow; T2 with median area black with contours darkened and lateral ends yellow-brown; T3 brown, but proximal corners yellow-brown; T4 and beyond completely dark brown; distally each tergum with a narrow yellowish transparent band. In lateral view, T1-2 completely yellow; T3-4 yellow-brown, but dorsally brown, extent of brown area increasing from proximal to distal; T5 and beyond completely brown. S1-3 completely yellow; S4-5 yellow-brown; hypopygium completely brown.

Description.

Head ( Fig. 70 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.23:0.08, 0.24:0.08, 0.22:0.08), distal antennal flagellomere longer than penultimate (0.15:0.06, 0.11:0.06), antenna longer than body (3.28, 2.78); antennal scrobes-frons shallow. Face flat or nearly so, with dense fine punctations, interspaces smooth and longitudinal median carina present. Frons smooth. Temple wide, punctate sculpture and interspaces clearly smooth. Inner margin of eyes straight throughout; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.09, 0.13). Malar suture present. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 70A, E, F, I ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout, interspaces smooth. Scutellum triangular, apex sloped and fused with BS, scutellar punctation scattered 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 smooth, shiny and nearly at the same level as mesoscutum (flat). Metanotum with BM wider than PFM (clearly differentiated); MPM circular without median longitudinal carina; AFM with a small lobe 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, proximal half straight or nearly so and with medium-sized sculpture 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 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 and dorsal furrow smooth, but ventral furrow with short parallel carina. Propleuron with fine punctations throughout and dorsally without a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove smooth, shiny and shallow, but visible; epicnemial ridge elongated more fusiform (tapering at both ends).

Legs ( Fig. 70A ). Ventral margin of fore telotarsus entire without seta, fore telotarsus proximally narrow and distally wide, and longer than fourth tarsomere (0.12, 0.08). Hind coxa with very finely punctate throughout, and dorsal outer depression absent. Inner spur of hind tibia longer than outer spur (0.22, 0.17), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.13, 0.11).

Wings ( Fig. 70K, L ). Fore wing with r vein straight; 2RS vein slightly concave; 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 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 curved and complete, but junction with 1-1A vein spectral. Hind wing with vannal lobe very narrow, subdistally and subproximally evenly convex, and setae evenly scattered in the margin.

Metasoma ( Fig. 70A, G, H, J ). Metasoma curved. Petiole on T1 finely sculptured on distal half, evenly narrowing distally (length 0.36, maximum width 0.17, minimum width 0.10), 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 0.19, length T2 0.19), edges of median area with little sculpture, median area as broad as long (length 0.19, maximum width 0.20, minimum width 0.08); T2 with scattered pubescence throughout. T3 as long as T2 (0.20, 0.19) and with scattered pubescence throughout. Pubescence on hypopygium dense.

Cocoons. Unknown.

Comments.

In lateral view, body is curved.

Male

( Fig. 71 A–F ). Similar in coloration and shape to female.

Etymology.

Diego Fernando Campos Moreno is a Colombian entomologist whose research has been focused on Braconidae . Currently, he is a Ph.D. student at El Colegio de la Frontera Sur ( ECOSUR), Chetumal, Quintana Roo, México.

Distribution.

Parasitized caterpillars were collected in Ecuador, Napo, Yanayacu Biological Station (Sendero Macuculoma and San Isidro Forest), during March 2006, December 2008, and January 2009 at 2,120 m and 2,208 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Undetermined species of Nymphalidae ( Ithomiinae) feeding on Cestrum megalophyllum Dunal and Cestrum sp. ( Solanaceae ). Caterpillars were collected in second and third instar.
