Diagnosis.

General body coloration brown-black, scape and all antennal flagellomeres (on both sides) brown; pedicel brown with an distal narrow yellow-brown ring; labrum light brown; mandible yellow-brown; glossa, maxillary and labial palps, and tegulae yellow; propleuron light brown with a tiny yellow-brown distal-ventral spot; dorsal and ventral furrows of pronotum somewhat lighter than mesosoma coloration. Eyes and ocelli silver. Fore and middle legs yellow except brown claws; hind legs yellow except black coxae with apex yellow, femora with a tiny brown area at the apex, tibiae with both ends brown, and tarsomeres brown, although basitarsus with a proximal yellow ring. Petiole on T1 black and sublateral ends yellow; T2 with median area black, adjacent area brown and lateral ends yellow with two elongate spots one on each side; T3 mostly brown although lateral ends with proximal half yellow/yellow-brown; T4 and beyond completely black; distally each tergum with a narrow yellow/whitish transparent band. In lateral view, T1-2 completely yellow; T3-4 yellow, but dorsally brown; T5 and beyond completely dark brown. S1 proximal half brown, distal half yellow; S2-3 completely yellow; S4 yellow, medially brown; penultimate sternum and hypopygium completely brown.

Description.

Head ( Fig. 94 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.24:0.06, 0.26:0.06, 0.25:0.06), distal antennal flagellomere longer than penultimate (0.15:0,05, 0.10:0.05), antenna longer than body (3.58, 2.88); 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, 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 (0.09, 0.12). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 94A, 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 indistinct throughout, in profile scutellum flat and on same plane as mesoscutum, phragma of the scutellum partially exposed; BS not overlapping the MPM; ATS demilune with quite a little complete parallel carinae; dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation wih large 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 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 a short concave 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 finely sculptured only ventrally and dorsally without a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove smooth, shiny and distinct; epicnemial ridge convex, teardrop-shaped.

Legs. Ventral margin of fore telotarsus excavated with conspicuous curved seta over this excavation, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.15, 0.09). Hind coxa with very finely punctate throughout, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.25, 0.21), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.23, 0.12).

Wings ( Fig. 94K, L ). Fore wing with r vein straight; 2RS vein straight; r and 2RS veins forming an angle 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 straight, 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. 94A, G, H, J ). Metasoma laterally compressed. Petiole on T1 finely sculptured throughout, parallel-sided in proximal half and then narrowing (length 0.37, maximum width 0.19, minimum width 0.09), 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 0.18, length T2 0.18), edges of median area with little sculpture, median area broader than long (length 0.18, maximum width 0.25, minimum width 0.07); T2 with scattered pubescence only distally. T3 longer than T2 (0.20, 0.18) and with scattered pubescence throughout. Pubescence on hypopygium dense.

Cocoons. Unknown.

Comments.

In females the hypopygium (S6) is the only sternum that is completely dark, penultimate sternum (S5) is yellow-brown.

Male.

The coloration is similar to female, except that colored adjacent area on T2 is not extensive and the two elongate spots are not noticeable, and besides T3 and beyond are completely brown. The body coloration is slightly darker than females and the hind tibia looks completely dark.

Etymology.

Grant Gentry is an American biologist with interests in tritrophic interactions, tropical caterpillars, and efficacies of lepidopteran larval defenses against parasitoids, with an emphasis on chemical defenses derived from food plants. He works at Samford University, Birmingham, AL, USA.

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Yanayacu Road), during May 2005 at 2,100 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Undetermined species of Notodontidae feeding on Myriocarpa sp. ( Urticaceae ). Caterpillar instar was not reported.
