Paratypes. • 5 (0 ♀, 3♂) (0 ♀, 2♂); EC-1732, YY-A022; same data as for holotype; ( PUCE) .

Diagnosis.

In lateral view, metasoma laterally compressed ( Fig. 145A, J ), hind coxa very finely punctate throughout ( Fig. 145A, J ), antenna shorter than body, scutellar punctation scattered throughout ( Fig. 145E, F ), edges of median area on T2 with little sculpture ( Fig. 145G, H ), petiole on T1 parallel-sided in proximal half and then narrowing ( Fig. 145G, H ), dorsal outer depression on hind coxa present ( Fig. 145A, J ), and fore wing with r vein curved, outer side of junction of r and 2RS veins forming a slight stub ( Fig. 145K ).

Coloration

( Fig. 145 A–K ). General body coloration polished black except scape, pedicel, and all antennal flagellomeres (on both sides) dark brown; mandibles yellow-brown; glossa, maxillary and labial palps, and tegulae yellow; clypeus, labrum, dorsal and ventral furrows of pronotum, epicnemial ridge, ventral edge of mesopleuron, lunules, BS, and PFM with brown-red/reddish tint. Eyes and ocelli silver. Fore and middle legs yellow except brown claws; hind legs yellow except black coxae only distally yellow (the yellow area is more extensive on the inner side), femora distally with a tiny brown spot, distal half of tibiae brown and proximally with a 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 narrow lateral ends yellow-brown; T3 and beyond completely brown; distally each tergum with a narrow yellow translucent band. In lateral view, T1-2 yellow-brown; T3 yellow-brown, but dorsally brown; T4 and beyond brown. S1-3 yellow-brown; S4 and beyond brown.

Description.

Head ( Fig. 145 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.25:0.08, 0.25:0.08, 0.24:0.08), distal antennal flagellomere longer than penultimate (0.15:0.06, 0.12:0.06), antenna shorter than body (3.68, 3.88); antennal scrobes-frons shallow. Face with distal half dented only laterally, punctations barely noticeable, interspaces smooth and longitudinal median carina absent. 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 (0.09, 0.11). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 145A, E, F, I ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout, interspaces wavy/lacunose. Scutellum long and slender, 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 carinae only proximally. 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 convex; MPM circular and bisected by a median longitudinal carina; AFM without setiferous lobes and not as well delineated as PFM; PFM thick and smooth; ATM proximally with a groove with some sculpturing and distally smooth. Propodeum with medium-sized punctation and without median longitudinal carina, proximal half weakly curved; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle without distal 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 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 (0.12, 0.07). Hind coxa finely punctate throughout, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.25, 0.17), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.15, 0.13).

Wings ( Fig. 145K ). 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; 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, 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. 145A, G, H, J ). Metasoma laterally compressed. Petiole on T1 with sculpture on distal half, virtually parallel-sided over most of length, but narrowing over distal 1/3, apex truncate (length 0.33, maximum width 0.17, 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 0.18, length T2 0.18), edges of median area with little sculpture and lateral grooves deep, median area broader than long (length 0.18, maximum width 0.20, minimum width 0.10); T2 scarce pubescence throughout. T3 longer than T2 (0.22, 0.18) and with scattered pubescence throughout.

Cocoons. Unknown.

Comments.

The body is slim and covered by dense pubescence.

Female.

Unknown.

Etymology.

Marianne (M) Alleyne is a Dutch-born entomologist interested in the physiological mechanisms involved in determining host range of an insect parasitoid. Her studies have mostly focused on the immune system and the metabolic pathways of the host in response to parasitization. Currently, she is a research scientist at UIUC, IL, USA.

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Sendero Pumayacu), during February 2005 at 2,000 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Undetermined species of Pyralidae feeding on undetermined species of Melastomataceae . Caterpillar instar was not reported.
