Diagnosis.

Propodeal spiracle without distal carina, inner margin of eyes straight throughout ( Fig. 75B ), distal antennal flagellomere longer than penultimate, median area between lateral ocelli without depression ( Fig. 75D ), in dorsal view, proximal half of propodeum more strongly curved ( Fig. 75G ), petiole on T1 evenly narrowing distally ( Fig. 75H, I ), dorsal outer depression on hind coxa present ( Fig. 75A, K ), edges of median area on T2 obscured by weak longitudinal stripes ( Fig. 75H, I ), and ore wing with r vein curved, outer side of junction of r and 2RS veins forming a slight stub ( Fig. 75L ).

Coloration

( Fig. 75 A–M ). General body coloration polished black except proximally scape, distally pedicel, laterally clypeus, dorsal furrow of pronotum, epicnemial ridge, and wall just above of dorsal ATS groove with light brown/yellow-brown tints; all antennal flagellomeres brown on both sides; labrum and tegula yellow; glossa, maxillary and labial palps pale yellow/ivory. Eyes and ocelli silver. Fore and middle legs yellow except brown claws; hind legs yellow except coxae black with apex yellow, tiny brown area at the apex of the femora, apex of the tibiae, and tarsomeres brown. Petiole on T1 black and sublateral areas yellow; T2 with median area black, wide adjacent area brown and lateral ends yellow; T3 brown, dark area coincides with the width of dark area formed by both median and adjacent areas on T2; however dark area on T3 not reaching the distal edge of T3, distally with a wide yellow-brown band and proximal corners of lateral ends yellow; T4 and beyond brown; distally each tergum with a narrow transparent yellow band. In lateral view, T1-2 completely yellow; T3-4 yellow, but dorsally brown, brown area larger on T4 than T3; T5 and beyond completely brown. S1-4 completely yellow; penultimate sternum yellow, distally with a medial brown spot; hypopygium completely brown.

Description.

Head ( Fig. 75 A–D ). Head triangular with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.29:0.10, 0.29:0.10, 0.30:0.10), distal antennal flagellomere longer than penultimate (0.16:0.07, 0.13:0.07), antenna longer than body (4.04, 3.93); antennal scrobes-frons shallow. Face flat or nearly so with dense fine punctations, interspaces smooth and longitudinal median carina present. Frons punctate. Temple wide, punctate and interspaces clearly smooth. Inner margin of eyes straight throughout, in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.10, 0.15). Malar suture present. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 75A, F, G, H ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout and interspaces wavy/lacunose. 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 with semicircular/parallel carinae. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation depressed centrally and with same kind of sculpture as mesoscutum. Metanotum with BM wider than PFM (clearly differentiated); MPM semicircular and without median longitudinal carina; AFM without setiferous lobes and not as well delineated as PFM; PFM thick and smooth; ATM proximally with semicircular/undulate carina and distally smooth. Propodeum without median longitudinal carina, proximal half curved 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 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 straight/angulate or nearly so; precoxal groove smooth, shiny and shallow, but visible; epicnemial ridge elongated more fusiform (tapering at both ends).

Legs ( Fig. 75A ). Ventral margin of fore telotarsus entire, but with a tiny curved seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.17, 0.10). Hind coxa finely punctate throughout, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.30, 0.25), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.20, 0.17).

Wings ( Fig. 75L, M ). 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 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 narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 75A, H, I, K ). Metasoma laterally compressed. Petiole on T1 finely sculptured only laterally, evenly narrowing distally (length 0.50, maximum width 0.25, minimum width 0.11) 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 0.25, length T2 0.25), edges of median area obscured by weak longitudinal stripes, median area as broad as long (length 0.25, maximum width 0.25, minimum width 0.10); T2 with scarce pubescence throughout. T3 longer than T2 (0.31, 0.25) and with scattered pubescence throughout. Pubescence on hypopygium dense.

Cocoons ( Fig. 75E ). White or beige bud-like cocoon with body ridge-shaped and evenly smooth silk fibers.

Male.

Unknown.

Etymology.

Edgard Enrique Palacio Goenaga is a Colombian entomologist. He has contributed to the knowledge of Hymenoptera , especially in ants and Ichneumonidae (mainly subfamily Pimplinae). Currently, he works at the Instituto Colombiano Agropecuario ( ICA), Colombia.

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station ( Río Pumayacu), during March 2009 at 2095 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is solitary.

Host.

Undetermined species of Saturniidae feeding on Psammisia sp. ( Ericaceae ). Caterpillar was collected in third instar.
