Type material.

Holotype: ECUADOR • 1♀; EC-1491, YY-A021; Napo, Yanayacu Biological Station , Yanayacu Forest ; cloud forest; 2,100 m; - 0.6, -77.883333; 24.i.2005; Lee Dyer leg.; cocoons away from host in running trail; adult parasitoids emerged on 21.iii.2005; ( PUCE) . Paratypes. • 17 (4♀, 5♂) (4♀, 4♂); EC-1491, YY-A021; same data as for holotype; ( PUCE) .

Diagnosis.

Shape of proximal half of propodeum more strongly curved in dorsal view ( Fig. 156F ), longitudinal median carina on face absent ( Fig. 156B ), lateral grooves delimiting the median area on T2 distally losing definition, edges of median area on T2 polished and followed by a deep groove ( Fig. 156G, H ), propodeum without median longitudinal carina ( Fig. 156F ), anteroventral contour of mesopleuron convex ( Fig. 156A, I ), and fore wing with r vein curved, outer side of junction of r and 2RS veins forming a distinct stub ( Fig. 156K ).

Coloration

( Fig. 156 A–L ). General body coloration polished black except scape brown distally with a yellow-brown ring; labrum, maxillary and labial palps, and tegulae yellow; pedicel and all antennal flagellomeres (on both sides) brown; labrum and mandibles brown-red/reddish. Eyes and ocelli silver. Fore and middle legs yellow except brown claw and tarsomeres with brown tints; hind legs yellow except coxae black, but distally yellow, femora distally with a small brown spot, distal 1/3 of tibiae brown, additionally tibiae proximally with a brown band, and tarsomeres brown. Petiole on T1 black and sublateral areas yellow; T2 with median area black, adjacent area brown with a silhouette well-defined, and lateral ends yellow; T3 mostly brown with proximal half of lateral ends yellow, proximally width of dark area coincides with the width of median and adjacent areas on T2, but distally dark area reaching the edge of T3; T4 and beyond completely brown; distally each tergum with an narrow yellow translucent band. In lateral view, T1-2 completely yellow; T3-4 yellow, but dorsally brown; T5 and beyond brown. S1-4 yellow; penultimate sternum and hypopygium brown.

Description.

Head ( Fig. 156 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.28:0.08, 0.29:0.08, 0.28:0.08), distal antennal flagellomere longer than penultimate (0.15:0.07, 0.12:0.07), antenna longer than body (3.33, 3.28); antennal scrobes-frons sloped and forming a shelf. Face flat or nearly so, with dense fine punctations, interspaces smooth and longitudinal median carina absent. Frons smooth. Temple wide, punctate 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, 0.14). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 156A, E, F, I ). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation distinct throughout, interspaces smooth. Scutellum long and slender, 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 only very partially overlapping the MPM; ATS demilune inner side with a row of foveae; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation sloped, smooth and shiny. Metanotum with BM wider than PFM (clearly differentiated); MPM circular without 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 sculpture distally without a well delimited smooth area. Propodeum without median longitudinal carina, proximal half curved with fine sculpture and distal half relatively polished; distal edge of propodeum with a flange at each side and short 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 smooth, but both dorsal and ventral furrows with short parallel carinae. Propleuron finely sculptured only ventrally 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 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 finely punctate throughout, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.31, 0.25), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.17, 0.16).

Wings ( Fig. 156K, L ). 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 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 absent proximally, but scattered distally.

Metasoma ( Fig. 156A, G, H, J ). Metasoma laterally compressed. Petiole on T1 finely sculptured only laterally, virtually parallel-sided over most of length, but barely narrowing at apex, apex truncate (length 0.41, maximum width 0.27, minimum width 0.17), and with scattered pubescence concentrated in the first distal third. Lateral grooves delimiting the median area on T2 distally losing definition (length median area 0.12, length T2 0.21), edges of median area polished, median area broader than long (length 0.12, maximum width 0.30, minimum width 0.16); T2 with scarce pubescence throughout. T3 longer than T2 (0.26, 0.21) and with scattered pubescence throughout. Pubescence on hypopygium dense.

Cocoons. Unknown.

Comments.

The ovipositor is long as in Sathon ( Fig. 156A, J ).

Male.

Coloration similar to female.

Etymology.

Marsha Wheeler was interested in molecular analyses of endocrine and nutritional factors that affect division of labor and health in honey bees ( Apis Mellifera Linnaeus) as a graduate student at UIUC, IL, USA.

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station ( Yanayacu Forest ), during January 2005 at 2,100 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Undetermined species of Lepidoptera feeding on Vismia sp. ( Clusiaceae ). Caterpillar instar was not reported.
