Diagnosis.

Median area on T2 as broad as long ( Figs 118H , 119G ), vertex in dorsal view quite wide ( Figs 118D , 119D ), edges of median area on T2 obscured by weak longitudinal stripes ( Figs 118H , 119G ) and lateral grooves delimiting the median area on T2 distally losing definition on T2 ( Figs 118I , 119H ), in lateral view, metasoma laterally compressed ( Figs 118A , 119A ), T3 longer than T2 ( Figs 118I , 119H ), inner margin of eyes diverging slightly at antennal sockets ( Figs 118B , 119B ), petiole on T1 evenly narrowing distally (wide base to a narrow apex, Figs 118H , 119G ) and finely sculptured ( Figs 118H , 119G ), propodeum without a median longitudinal dent ( Figs 118G , 119F ), and fore wing with r vein straight, outer side of junction of r and 2RS veins forming a stub ( Figs 118L , 119K ).

General body coloration brown-to-reddish except all antennal flagellomeres dark brown on both sides; labrum and mandibles yellow-brown; glossa, maxillary and labial palps, and tegulae yellow. Eyes gray/black and ocelli brownish/reddish (in preserved specimen). Fore and middle legs dark yellow, tarsomeres with a brownish tint, and claws brown; hind legs dark yellow except dark brown coxae, femora apically with a tiny brown dot, tibiae with distal half brown and proximally with a narrow brown band, and tarsomeres brown. Petiole on T1 light brown, contours darkened and sublateral areas yellow-brown; T2 with median area and lateral ends brown; T3 and beyond completely brown; distally each tergum with a yellowish transparent band barely noticeable. In lateral view, T1-2 completely brown-reddish; T3 brown-reddish, but dorsally brown; T4 and beyond completely brown. S1-3 brown-reddish; S4 and beyond completely brown.

Description.

Head ( Fig. 118 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.22:0.05, 0.21:0.05, 0.22:0.05), distal antennal flagellomere longer than penultimate (0.13:0.45, 0.11:0.45), antenna longer than body (3.08, 2.53); antennal scrobes-frons sloped and forming a shelf. Face convex, dense and finely punctate, interspaces smooth and longitudinal median carina present. Frons rugose. 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 faint. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally quite wide.

Mesosoma ( Fig. 118A, E–G, J ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout, interspaces wavy/lacunose. Scutellum shield-shaped, apex sloped and fused with BS, but not in the same plane, scutellar punctation distinct peripherally and absent centrally, 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 inner side with a row of foveae; 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 upward; MPM semicircular without median longitudinal carina; 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 without median longitudinal carina, proximal half weakly 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 long radiating carinae. Pronotum with a faint 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 without a carina. Metasternum convex. Contour of mesopleuron convex; precoxal groove smooth, shiny and shallow, but visible; epicnemial ridge elongated more fusiform (tapering at both ends).

Legs. Ventral margin of fore telotarsus entire without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.11, 0.08). Hind coxa finely punctate throughout, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.20, 0.16), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.14, 0.11).

Wings ( Fig. 118L, M ). Fore wing with r vein straight; 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 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. 118A, H, I, K ). Metasoma laterally compressed. Petiole on T1 finely sculptured distally, but only laterally, evenly narrowing distally (length 0.30, maximum width 0.17, minimum width 0.07), and with scattered pubescence on distal half only laterally. Lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 (length median area 0.17, length T2 0.17), edges of median area obscured by weak longitudinal stripes, median area as broad as long (length 0.17, maximum width 0.16, minimum width 0.07); T2 with pubescence in distal half. T3 longer than T2 (0.19, 0.17) and with scattered pubescence throughout. Pubescence on hypopygium dense.

Cocoons. Unknown.

Comments.

The mesoscutum is elongated; dorsally, the head is wide; the median area of vertex is not dinted and has a longitudinal groove. In the holotype, only the coxae and the trochanters are present. Both sexes with slim bodies.

Male

( Fig. 119 A–L ). Similar in coloration to females. Body size 2.22 mm. The median area on T2 darker in coloration than females.

Etymology.

Jerry A. Powell’s major fields are systematics, comparative biology, rearing programs, and faunal inventories. He has concentrated his efforts in New World Tortricinae ( Tortricoidea) and Ethmiinae ( Gelechioidea). He is director emeritus of the Essig (Edward O. Essig) Museum at the University of California, Berkeley, CA, USA.

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Yanayacu Road), during December 2006 at 2,100 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Undetermined species of Nymphalidae ( Ithomiinae) feeding on Schoenobiblus cf. peruvianus ( Thymeliaceae ). Caterpillar was collected in second instar.
