Diagnosis.

Vertex in lateral view rounded ( Fig. 41C ), dorsal carina delimiting a dorsal furrow on propleuron absent ( Fig. 41A, J ), inner margin of eyes straight throughout ( Fig. 41B ), fore wing with vein 2-1A tubular throughout, r vein curved, outer side of junction of r and 2RS veins forming a distinct stub ( Fig. 41L ), median area on T2 broader than long, edges of median area on T2 obscured by weak longitudinal stripes ( Fig. 41H, I ), antenna longer than body, scutellum in profile flat and on same plane as mesoscutum, in dorsal view, proximal half of propodeum weakly curved ( Fig. 41G ), petiole on T1 evenly narrowing distally ( Fig. 41H, I ), and dorsal outer depression on hind coxa present ( Fig. 41A, K ).

Coloration

( Fig. 41 A–M ). General body coloration black except proximally scape, distally pedicel, labrum, and mandibles yellow-brown; all antennal flagellomeres brown on both sides; glossa, maxillary and labial palps, and tegulae yellow. Eyes silver and ocelli yellowish. Fore and middle legs yellow with brown claws; hind legs yellow, but a dot at the apex of femora, distal half of tibiae and tarsomeres brown. Petiole on T1 black and sublateral areas yellow; T2 with median and adjacent areas black, and lateral ends yellow/yellow-brown; T3 medially brown, but distal half with tints yellow/yellow-brown; T4 and beyond completely brown; distally each tergum with a narrow yellow transparent band. In lateral view, T1-2 completely yellow; T3-4 yellow, but dorsally brown; T5 and beyond completely brown. S1-3 completely yellow; S4 yellow, but medial with a brown spot; penultimate sternum yellow, medially brown; hypopygium completely brown.

Description.

Head ( Fig. 41 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.24:0.07, 0.24:0.07, 0.24:0.07), distal antennal flagellomere longer than penultimate (0.15:0.06, 0.12:0.06), antenna longer than body (3.53, 2.63); 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 and interspaces clearly smooth. Inner margin of eyes straight throughout; 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 without depression. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 41A, F, G, J ). Mesosoma dorsoventrally convex. Mesoscutum distal half with a central dent, 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 quite a little complete parallel carinae; dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation with a smooth and shiny sloped transverse strip. Metanotum with BM wider than PFM (clearly differentiated); MPM semicircular 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 with medium-sized sculpture without median longitudinal carina, proximal half weakly curved 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 distally framed by faintly concave/wavy 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 carina. Propleuron with fine punctations throughout 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, but with a tiny curved seta, fore telotarsus proximally narrow and distally wide, and longer than fourth tarsomere (0.14, 0.09). Hind coxa with medium-size punctate throughout, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.25, 0.19), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.16, 0.12).

Wings ( Fig. 41L, 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 tubular throughout; tubular vein 1 cu-a straight, incomplete/broken, and not reaching the edge of 1-1A vein. Hind wing with vannal lobe narrow, subdistally straightened, subproximally straightened, and setae absent proximally, but scattered distally.

Metasoma ( Fig. 41A, H, I, K ). Metasoma cylindrical . Petiole on T1 finely sculptured on distal half, evenly narrowing distally (length 0.33, maximum width 0.27, minimum width 0.10), petiole 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 0.18, length T2 0.18), edges of median area obscured by weak longitudinal stripes, median area broader than long (length 0.18, maximum width 0.20, minimum width 0.10); T2 with scattered pubescence throughout. T3 longer than T2 (0.21, 0.18) and with scattered pubescence throughout. Pubescence on hypopygium dense.

Cocoon ( Fig. 41E ). White bud-like cocoon with silk fibers evenly smooth.

Etymology.

Carina Chicaiza is an Ecuadorian biologist who has helped in the identification of the food plants of the most common lepidopteran species collected at the Yanayacu Biological Station.

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Sendero Macuculoma), during February 2009 at 2,108 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is solitary.

Host.

Undetermined species of Noctuidae feeding on Chusquea scandens ( Poaceae ). Caterpillar was collected in second instar.
