ECUADOR • 1♀; EC-25275, YY-A218; Napo, Yanayacu Biological Station, Yanayacu Road ; cloud forest; 2,100 m; - 0.583333, -77.866667; 13.viii.2007; Rafael Granizo leg.; caterpillar collected in third instar; white bud-like cocoon formed on 06.ix.2007; adult parasitoid emerged on 20.x.2007; ( PUCE).

Diagnosis.

Medioanterior pit of metanotum elongated with some sculpture inside and not covered by medioposterior band of scutellum ( Fig. 74G ), transscutal articulation with small homogeneous carinated foveae ( Fig. 74F ), inner margin of eyes straight throughout, median area on T2 as broad as long, edges of median area on T2 obscured by weak longitudinal stripes ( Fig. 74H, K ), ventral margin of fore telotarsus entire without seta, anteroventral contour of mesopleuron straight/angulate or nearly so ( Fig. 74A, I ), propleuron with fine punctations throughout ( Fig. 74A, I ), longitudinal median carina on face present, surface of metasternum convex, dorsal outer depression on hind coxa absent ( Fig. 74A ), and fore wing with r vein slightly curved, outer side of junction of r and 2RS veins forming a stub ( Fig. 74D ).

Coloration

( Fig. 74 A–K ). General body coloration polished black, except labrum, mandibles, maxillary and labial palps, and tegulae with yellow-brown tints; all antennal flagellomeres brown on both sides. Eyes silver and ocelli reddish (in preserved specimen). Fore and middle legs yellow-brown except brown claws; hind legs yellow-brown except black-brown coxae, femora with a brown spot at the apex, both ends of tibiae brown, and tarsomeres brown. Petiole on T1 black, and sublateral areas yellow-brown; T2 with median area black, adjacent area brown, and lateral ends narrow and yellow-brown; T3 and beyond black; distally each tergum with a narrow whitish transparent band. In lateral view, T1-3 yellow-brown; T4 and beyond black-brown. S1-3 yellow-brown; S4 and beyond brown.

Description.

Head ( Fig. 74A, C ). Head triangular with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.26:0.06, 0.26:0.06, 0.25:0.06), distal antennal flagellomere longer than penultimate (0.16:0.06, 0.11:0.06), antenna longer than body (3.68, 2.68); antennal scrobes-frons shallow. Face with lateral depression with scattered finely punctate, interspaces smooth and longitudinal median carina present. Frons punctate. 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, 0.13). Malar suture absent or difficult to see. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 74A, F, G, I ). Mesosoma dorsoventrally convex. Mesoscutum 1/4 distal with a central dent, punctation distinct throughout, 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 a little, complete parallel carinae; dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation with small and homogeneous 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 sculpture inside; 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 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 and dorsal furrow smooth, but ventral furrow with short parallel carinae. Propleuron with fine punctations throughout and dorsally without a carina. Metasternum convex. Contour of mesopleuron straight/angulate or nearly so; 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 proximally narrow and distally wide slightly, and longer than fourth tarsomere (0.10, 0.08). Hind coxa finely punctate throughout, and dorsal outer depression absent. Inner spur of hind tibia longer than outer spur (0.23, 0.17), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus slightly longer than fourth tarsomere (0.14, 0.12).

Wings ( Fig. 74D, E ). Fore wing with r vein slightly curved; 2RS vein slightly concave; 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 absent; vein 2-1A proximally tubular and distally spectral, although sometimes difficult to see; tubular vein 1 cu-a curved, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe very narrow, subdistally and subproximally straightened, setae evenly scattered in the margin.

Metasoma ( Fig. 74A, H, J, K ). Metasoma laterally compressed. Petiole on T1 finely sculptured only laterally, parallel-sided in proximal half and then narrowing (length 0.38, maximum width 0.20, minimum width 0.10), 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 0.20, length T2 0.20), edges of median area obscured by weak longitudinal stripes; median area as broad as long (length 0.20, maximum width 0.21, minimum width 0.10); T2 scarce pubescence throughout. T3 longer than T2 (0.22, 0.20) and with scattered pubescence throughout.

Cocoon ( Fig. 74B ). White or beige bud-like cocoon with evenly smooth silk fibers.

Comments.

The metasomal segments are desiccated and shrunken. The mesosoma is stout.

Female.

Unknown.

Etymology.

Doris Lagos-Kutz, Peruvian-American entomologist, who carries out research on aphid systematics and soybean host plant resistance.

Biology.

The lifestyle of this parasitoid species is solitary.

Host.
