Paratypes. • 9 (4♀, 3♂) (2♀, 0 ♂); EC-14572, YY-A094; same data as for holotype; ( PUCE) .

Diagnosis.

Precoxal groove with transverse lineate sculpture ( Fig. 217A, I ), scutellar punctation distinct peripherally, absent centrally ( Fig. 217F ), vertex in dorsal view quite wide, mesoscutum punctation distinct proximally but absent distally ( Fig. 217E ), T3 longer than T2 ( Fig. 217H ), propodeum with a median longitudinal dent, petiole on T1 finely sculptured ( Fig. 217G, H ), lateral grooves delimiting the median area on T2 distally losing definition on T2 ( Fig. 217G ), and fore wing with r vein straight, outer side of junction of r and 2RS veins forming a stub.

Coloration

( Fig. 217 A–K ). General body coloration polished black except scape proximally yellow-brown/reddish and distally brown; pedicel yellow-brown; first four-five proximal antennal flagellomeres dorsally lighter (light brown) than ventrally (dark brown), remaining flagellomeres dark brown on both sides; labrum, mandible, and tegulae light yellow-brown; glossa, maxillary and labial palps yellow. Eyes gray/black and ocelli reddish (in preserved specimen). Fore and middle legs dark yellow, except brown claws, telotarsus and penultimate tarsomeres of middle legs with brown tints; hind legs dark yellow except black coxae, distal 3/4 of femora brown, distal half of tibiae brown, and tarsomeres brown although basitarsus proximally with a yellow band. Petiole on T1 brown and sublateral areas yellow-brown; T2 with median area and lateral ends brown; T3 and beyond completely brown; distally each tergum with a very narrow whitish translucent band. In lateral view, T1-3 yellow-brown; T4 and beyond brown. S1-3 yellow, but medially brown; S4 and beyond completely brown.

Description.

Head ( Fig. 217 A–D ). Head rectangle with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.19:0.06, 0.19:0.06, 0.19:0.06), distal antennal flagellomere longer than penultimate (0.13:0.05, 0.08:0.05), antenna longer than body (2.63, 2.17); antennal scrobes-frons shallow. Face flat or nearly so, punctate-lacunose, interspaces wavy and longitudinal median carina present. Frons smooth. Temple quite wide, punctate-lacunose and interspaces wavy. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL subequal in length with OOL (0.09, 0.10). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally quite wide.

Mesosoma ( Fig. 217A, E, F, I ). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation proximally distinct, but distally absent/dispersed, interspaces wavy/lacunose. Scutellum short and broad, apex sloped and fused with BS, but not in the same plane, scutellar punctation distinct peripherally and absent centrally, in profile scutellum flat and on same plane as mesoscutum, phragma of the scutellum partially exposed; BS mostly overlapping the MPM; ATS demilune with short stubs delineating the area; dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation with small and homogeneous foveae, area just behind transscutal articulation with a smooth and shiny sloped transverse strip. 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, smooth and with lateral ends rounded; ATM proximally with a groove with some sculpturing and distally smooth. Propodeum with a median longitudinal dent, but no trace of median longitudinal carina, proximal half straight or nearly so and with fine sculpture, and distal half with a mix of coarse sculpture and rugae; 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 long 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 rugae and dorsally with a carina. Metasternum flat or nearly so. Contour of mesopleuron convex; precoxal groove deep with transverse lineate sculpture; epicnemial ridge convex, teardrop-shaped.

Legs ( Fig. 217A ). Ventral margin of fore telotarsus slightly excavated and with a tiny curved seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.12, 0.09). Hind coxa with punctation only on ventral surface, dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.25, 0.15), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.11, 0.10).

Wings ( Fig. 217K ). Fore wing with r vein straight; 2RS vein straight; r and 2RS veins forming an angle 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 present only proximally as spectral vein; tubular vein 1 cu-a straight, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 217A, G, H, J ). Metasoma laterally compressed. Petiole on T1 completely smooth and polished, with faint, satin-like sheen, parallel-sided in proximal half and then narrowing (length 0.31, maximum width 0.14, minimum width 0.08), 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 0.11, length T2 0.11), edges of median area polished and lateral grooves deep, median area broader than long (length 0.11, maximum width 0.13, minimum width 0.08); T2 with scattered pubescence only distally. T3 longer than T2 (0.18, 0.10) and with pubescence more notorious in distal half. Pubescence on hypopygium scattered.

Cocoons. Adhered to the larval cuticle, but characteristic unknown.

Comments.

In lateral view, the head is wide and looks globose ( Fig. 217C ) and the body is short and stout ( Fig. 217A ).

Male.

Coloration darker than female; the hind femora is completely brown.

Etymology.

Tolulope (Tolu) Adebimpe Agunbiade is a Nigerian-born entomologist who, as a graduate student at UIUC, IL, USA, studied the population genetics of the insects that attack cowpeas, also known as black-eyed peas. Currently, she is a lecturer at the University of Florida's Entomology and Nematology Department in Gainesville, Florida, USA .

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Km 33 vía Tena), during May 2006.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Undetermined species of Noctuidae feeding on Miconia sp. ( Melastomataceae ). Caterpillar was collected in late instar or pre-pupa.
