Coloration

( Fig. 139 A–K ). General body coloration polished black except scape and all antennal flagellomeres (on both sides) dark brown; pedicel, labrum and mandibles brown-red/reddish; glossa, maxillary and labial palps, and tegulae yellow; lunules, BS, PFM and BS with brown-red/reddish tints. Eyes silver and ocelli yellowish. Fore and middle legs yellow except brown claws and tarsomeres with brown tints; hind legs yellow except black coxae with apex yellow, femora with brown apex, distal half of tibiae brown and distally with a small brown band, and tarsomeres brown. Petiole on T1 black, contours darkened and sublateral areas yellow; T2 with median and wide adjacent areas brown, and lateral ends yellow-brown; T3 brown except a small yellow-brown area in proximal corners; T4 and beyond brown; distally each tergum with a narrow whitish translucent band. In lateral view, T1-2 yellow; T3-4 yellow, but dorsally yellow-brown, the extent of yellow-brown area increasing from proximal to distal; T5 and beyond completely brown. S1-2 yellow; S3 proximal half yellow, distal half brown; S4 and beyond brown.

Description.

Head ( Fig. 139 A–D ). Head elongate with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.26:0.09, 0.28:0.09, 0.25:0.09), distal antennal flagellomere longer than penultimate (0.13:0.05, 0.10:0.07), antenna longer than body (3.28, 2.83); antennal scrobes-frons sloped and forming a shelf. Face fine and punctate-lacunose, interspaces wavy and with lateral depression only middle, and longitudinal median carina absent. Frons smooth. Temple wide, punctations barely noticeable and interspaces clearly smooth. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.08, 0.13). Malar suture absent or difficult to see. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 139A, E, F, I ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout, interspaces smooth. Scutellum long and slender, apex sloped and fused with BS, but not in the same plane, scutellar punctation scattered throughout, in profile scutellum flat and on same plane as mesoscutum, phragma of the scutellum partially exposed; BS not overlapping the MPM; ATS demilune only inner side with sculpture; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation nearly at the same level as mesoscutum (flat) and with same kind of sculpture as mesoscutum. Metanotum with BM wider than PFM (clearly differentiated); MPM circular with some sculpturing inside; AFM without setiferous lobes and not as well delineated as PFM; PFM thick, smooth and with lateral ends rounded; ATM proximally with sculpture distally without a well delimited smooth area. Propodeum with a median longitudinal dent, but no trace of median longitudinal carina, proximal half weakly curved with medium-sized sculpture and distal half slightly rugose; 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 long 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 finely sculptured only ventrally and dorsally with a carina. Metasternum convex. 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 (0.14, 0.12). Hind coxa finely punctate throughout, and dorsal outer depression absent. Inner spur of hind tibia longer than outer spur (0.30, 0.21), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.18, 0.17).

Wings ( Fig. 139K ). 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; 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 straight, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 139A, G, H, J ). Metasoma laterally compressed. Petiole on T1 with a mix of fine rugae and punctate sculpture over most of the surface, virtually parallel-sided over most of length, but barely narrowing over distal 1/3, apex truncate (length 0.41, maximum width 0.19, 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 0.21, length T2 0.21), edges of median area obscured by weak longitudinal stripes, median area broader than long (length 0.21, maximum width 0.23, minimum width 0.09); T2 with scattered pubescence throughout. T3 longer than T2 (0.24, 0.21) and with pubescence more notorious in distal half. Pubescence on hypopygium dense.

Cocoons. Unknown.

Comments.

In some specimens of the same sample, the coloration of sterna is a little different, distally all are brown with a longitudinal yellow band; the middle coxae proximally with a dorsal brown spot. In some specimens (e.g., EC-2807), the pronotum and the propleuron with brown-red/reddish tints. The malar space in this species is wide. The area between antennal scrobes is dented. The shape of the body is very elongated.

Male.

Similar in coloration to females. The same color variation found in females are also present in males.

Etymology.

Kevin P. Johnson is an American biologist. His major fields of interest are avian and insect systematics, host-parasite coevolution, island biogeography, population genetics, and behavioral ecology. He works at the Illinois Natural History Survey, Champaign, IL, USA.

Distribution.

Parasitized caterpillars were collected in Ecuador, Napo, Yanayacu Biological Station (Yanayacu Road), during May 2005 and April 2009 at 2,100 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Undetermined species of Erebidae ( Arctiinae) feeding on Rubus sp. ( Rosaceae ). Caterpillar was collected in second instar.
