Diagnosis.

Petiole on T1 virtually parallel-sided, but narrowing over distal 1/3 ( Fig. 135H, I ), distal edge on T2 straight ( Fig. 135H, I ), lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 ( Fig. 135H ), edges of median area on T2 obscured by strong longitudinal stripes ( Fig. 135H, I ), T3 longer than T2 ( Fig. 135I ), distal antennal flagellomere longer than penultimate, mesoscutum punctation distinct throughout ( Fig. 135F ), in lateral view, metasoma curved ( Fig. 135A, K ), dorsal outer depression on hind coxa present ( Fig. 135A, K ), and fore wing with r vein curved, outer side of junction of r and 2RS veins forming a stub ( Fig. 135L ).

Coloration

( Fig. 135 A–M ). General body coloration polished black except pedicel brown-red/reddish; scape brown-red/reddish, but distally with a brown ring; all antennal flagellomeres dark brown on both sides; clypeus brown/reddish; mandibles proximally reddish and distally yellow-brown; contours of labrum yellow-brown, but remaining area brown-red/reddish; glossa, maxillary and labial palps, and tegulae yellow; lunules and BS with a distal narrow brown-red/reddish as well as PFM and BM; both dorsal and ventral furrows of pronotum, epicnemial ridge, and ventral edge of mesopleuron with brown-red/reddish tints. Eyes and ocelli silver. Fore and middle legs yellow except brown claws, and middle telotarsus light brown; hind legs yellow except black coxae with apex yellow, femora with a small brown area in the apex, tibiae with 1/3 distal and proximally with a small brown band, and tarsomeres brown. Petiole on T1 black and sublateral areas yellow; T2 with median and adjacent areas brown, adjacent area with contours well-defined, and lateral ends yellow-brown; T3 completely brown except two notches each one at the proximal corners of T3; T4 and beyond brown; distally each tergum with a narrow whitish translucent band. In lateral view, T1-2 yellow; T3 yellow, dorsally brown-reddish; T4 and beyond brown. S1-4 yellow; penultimate sternum and hypopygium brown-reddish.

Description.

Head ( Fig. 135 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.29:0.12, 0.29:0.12, 0.29:0.12), distal antennal flagellomere longer than penultimate (0.20:0.07, 0.15:0.07), antenna longer than body (4.14, 3.18); antennal scrobes-frons sloped and forming a shelf. Face distal half dented only laterally, punctations barely noticeable, interspaces smooth and longitudinal median carina present. 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 (0.11, 0.16). Malar suture present. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 135A, F, G, J ). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation distinct throughout, interspaces smooth. Scutellum triangular, 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 only very partially overlapping the MPM; ATS demilune with complete undulate/reticulate carinae; dorsal ATS groove with semicircular/parallel carinae. 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 oval/circular with a short proximal carina; AFM with a small lobe and not as well delineated as PFM; PFM thick, smooth and with lateral ends rounded; ATM proximally sculptured and distally without a well delimited smooth area. Propodeum with a median longitudinal dent, but no trace of median longitudinal carina, propodeum relatively polished although with some medium-sized sculpture, proximal half weakly curved; 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 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 convex, teardrop-shaped.

Legs. Ventral margin of fore telotarsus entire without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.15, 0.12). Hind coxa with dorsal half sparsely punctate, ventral half densely punctate, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.33, 0.26), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.18, 0.15).

Wings ( Fig. 135L, M ). Fore wing with r vein slightly curved; 2RS vein slightly convex to convex; r and 2RS veins forming a weak, even curve at their junction and outer side of junction forming a distinct 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 a small smooth area; vein 2CUa absent and vein 2CUb spectral; vein 2 cu-a absent; 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 straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 135A, H, I, K ). Metasoma curved. 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 0.51, maximum width 0.22, minimum width 0.18) and with scattered pubescence on distal half. Lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 (length median area 0.24, length T2 0.24), edges of median area obscured by strong longitudinal stripes, median area broader than long (length 0.24, maximum width 0.40, minimum width 0.15); T2 with scattered pubescence throughout. T3 longer than T2 (0.30, 0.24) and with scattered pubescence throughout.

Cocoon ( Fig. 135E ). Beige oval cocoon with messy/disordered/fluffy silk fibers; body of cocoon with disorganized and tangled silk.

Comments.

The petiole on T1 medially with lateral margins slightly curved (convex, Fig. 135H ); the propleuron looks slim ( Fig. 135A ).

Female.

Unknown.

Etymology.

José Arturo Simbaña is one of the gusaneros at Yanayacu Biological Station and thus responsible for collecting much of the Ecuadorean material for this study.

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Yanayacu Road), during July 2004 at 2,100 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is solitary.

Host.

Undetermined species of Lepidoptera feeding on Rubus sp. ( Rosaceae ). Caterpillar was collected in third instar.
