Paratypes. • 86 (9♀, 4♂) (73♀, 0 ♂); EC-40241, YY-A000; same data as for holotype; ( PUCE) .

Diagnosis.

Medioanterior pit of metanotum circular or oval with a short proximal carina ( Fig. 157E, F ), vertex in dorsal view wide ( Fig. 157D ), scutellar punctation indistinct throughout ( Fig. 157E, F ), dorsal furrow of pronotum without a smooth band ( Fig. 157A, C, I ), dorsal carina delimiting a dorsal furrow on propleuron present ( Fig. 157A, C, I ), anterior furrow of metanotum without setiferous lobes ( Fig. 157F ), axillary trough of scutellum with sculpture ( Fig. 157E, F ), lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2, edges of median area polished and followed by a deep groove ( Fig. 157G, H ), propodeum without median longitudinal carina ( Fig. 157F ), anteroventral contour of mesopleuron convex ( Fig. 157A, I ), and fore wing with r vein curved, outer side of junction of r and 2RS veins forming a stub ( Fig. 157K ).

Coloration

( Fig. 156 A–K ). General body coloration polished black except pedicel brown distally with a yellow-brown ring; scape and all antennal flagellomeres (on both sides) brown; labrum, mandibles and glossa yellow-brown; maxillary and labial palps, and tegulae yellow; propleuron, both dorsal and ventral furrows of pronotum, epicnemial ridge, ventral edge of mesopleuron, distal edges of mesoscutum, dorsal ATS groove, lunules, BS, PFM, BM and lateral ends of metapleuron with brown-red/reddish tints. Eyes and ocelli silver. Fore, middle and hind legs yellow; however, coloration in tibiae and tarsomeres with light yellow-brown tints. Petiole on T1 with two colorations, proximal half brown-red/reddish and distal half brown, contours darkened and sublateral areas yellow; T2 with median and adjacent areas brown, adjacent area narrow reaching very close to the contours of median area, and lateral ends yellow; T3 medially with a brown area which proximal width coincides with the width of median and adjacent areas on T2, distally the brown area forming like three projections not reaching the distal edge of T3, remaining area of T3 yellow; T4 and beyond completely brown, coloration darkened from proximal to distal; distally each tergum with a narrow yellow translucent band. In lateral view, T1-2 yellow; T3 and beyond yellow, but dorsally brown, the extent of brown area remains almost constant from proximal to distal. All sterna yellow, but hypopygium medially brown.

Description.

Head ( Fig. 157 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.23:0.06, 0.24:0.06, 0.23:0.06), distal antennal flagellomere longer than penultimate (0.15:0.05, 0.12:0.05), antenna longer than body (3.48, 2.73); antennal scrobes-frons sloped and forming a shelf. Face flat or nearly so, with dense fine punctations, interspaces smooth and longitudinal median carina present. Frons smooth. Temple narrow, 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 (0.09, 0.13). Malar suture present. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 157A, E, F, I ). Mesosoma dorsoventrally convex. Mesoscutum 1/4 distal with a central dent, punctation distinct throughout, interspaces smooth. Scutellum long and slender, apex sloped and fused with BS, but not in the same plane, scutellar punctation indistinct 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 smooth. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation depressed centrally and with same kind of sculpture as mesoscutum. Metanotum with BM convex; MPM oval/circular with a short proximal carina; AFM without setiferous lobes and not as well delineated as PFM; PFM thick and smooth; ATM proximally with sculpture distally without a well delimited smooth area. Propodeum with indistinct sculpture, without median longitudinal carina, 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 dorsal furrow distinctive only proximally, dorsally without a smooth band; central area of pronotum smooth, and ventral furrow with short parallel carinae. Propleuron finely sculptured only ventrally and dorsally with 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 slightly excavated and with a tiny curved seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.13, 0.09). Hind coxa finely punctate throughout, and dorsal outer depression absent. Inner spur of hind tibia longer than outer spur (0.21, 0.18), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.17, 0.14).

Wings ( Fig. 157K ). 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 straight; 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; 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 and complete, but junction with 1-1A vein spectral. Hind wing with vannal lobe very narrow, subdistally and subproximally evenly convex, and setae evenly scattered in the margin.

Metasoma ( Fig. 157A, G, H, J ). Metasoma cylindrical . Petiole on T1 finely sculptured distal, but only laterally, parallel-sided in proximal half and then narrowing (length 0.34, maximum width 0.20, minimum width 0.11), 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 0.22, length T2 0.22), lateral grooves deep, median area as broad as long (length 0.22, maximum width 0.22, minimum width 0.10); T2 with scarce pubescence throughout. T3 longer than T2 (0.26, 0.22) and with scattered pubescence throughout. Pubescence on hypopygium dense.

Cocoons. Unknown.

Comments.

In some females, the S4 and beyond medially are brown.

Male.

Similar in coloration to female.

Etymology.

May Roberta Berenbaum is a renowned American entomologist known for elucidating chemical mechanisms underlying interactions between insects and their food plants, including detoxification of natural and synthetic chemicals, and for applying ecological principles in developing sustainable management practices for natural and agricultural communities. Currently, she is a professor and head of the Department of Entomology at UIUC, IL, USA, and also Editor-in-Chief of Proceedings of the National Academy of Sciences of the USA.

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Yanayacu Road), during August 2009 at 2,100 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Undetermined species of Noctuidae feeding on Burmeistera borgensis ( Campanulaceae ). Caterpillar was collected in fourth instar.
