Paratypes. • 24 (5♀, 6♂) (10♀, 3♂); EC-28553, YY-A071; same data as for holotype; ( PUCE) .

Diagnosis.

Petiole on T1 with a mix of sculptures: finely rugulate and punctate ( Fig. 137G, H ), lateral grooves delimiting the median area on T2 distally losing definition on T2 ( Fig. 137G, H ), and fore wing with r vein straight, outer side of junction of r and 2RS veins forming a stub ( Fig. 137K ).

Coloration

( Fig. 137 A–L ). General body coloration satin black except scape and all antennal flagellomeres dark brown on both sides; pedicel brown-red/reddish; labrum and mandibles yellow-brown; glossa, maxillary and labial palps, and tegulae yellow; propleuron, dorsal and ventral furrows of pronotum, epicnemial ridge, distal corner of mesoscutum that expand forward in one longitudinal band at each side and goes until distal 1/3 of mesoscutum, lunules, BS, AFM, PFM, and medially propodeum with brown-red/reddish tints. Eyes silver and ocelli reddish (in preserved specimen). Fore and middle legs yellow except brown claws and tarsomeres with brown tints; hind legs yellow except black coxae with apex yellow/yellow-brown, femora with a small brown area in the apex, distal half of tibiae brown with a small distal brown band, and tarsomeres brown. Petiole on T1 proximally brown-red/reddish, distally black, contours darkened and sublateral areas yellow; T2 with median and adjacent areas brown, and lateral ends yellow-brown; T3 completely brown except a small area in the proximal half of lateral corners; T4 and beyond brown; distally each tergum with a narrow whitish translucent band. In lateral view, T1-3 dorsally yellow-brown, ventrally yellow; T4 and beyond brown. S1-3 yellow; S4 and beyond brown.

Description.

Head ( Fig. 137 A–D ). Head rhomboid with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.23:0.08, 0.21:0.08, 0.21:0.08), distal antennal flagellomere longer than penultimate (0.13:0.07, 0.11:0.07), antenna longer than body (3.13, 2.73); antennal scrobes-frons sloped and forming a shelf. Face flat or nearly so, with dense fine punctation, interspaces smooth and longitudinal median carina present. 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 (0.10, 0.15). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 137A, E, F, I ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout, interspaces smooth. 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 complete undulate/reticulate carinae, dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation sloped and with same kind of sculpture as mesoscutum. Metanotum with BM wider than PFM (clearly differentiated); MPM semicircular without median longitudinal carina; AFM with a small lobe and not as well delineated as PFM; PFM thick, smooth and with lateral ends rounded; ATM proximally with semircular/undulate carina and distally smooth. Propodeum relatively polished 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 long radiating carinae. Pronotum with a distinct dorsal furrow, dorsally with a well-defined smooth band; central area of pronotum smoot, 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 convex, teardrop-shaped.

Legs. Ventral margin of fore telotarsus entire without seta, fore telotarsus proximally narrow and distally wide, and longer than fourth tarsomere (0.12, 0.05). Hind coxa finely punctate throughout, and dorsal outer depression present. Inner spur of hind tibia much 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 (0.15, 0.12).

Wings ( Fig. 137K, L ). Fore wing with r vein straight; 2RS vein slightly convex to convex; r and 2RS veins forming a weak, even curve at their junction and outer side of junction forming a distinct 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; vein1 cu-a straight. Hind wing with vannal lobe very narrow, subdistally and subproximally straightened, and setae present proximally, but absent distally.

Metasoma ( Fig. 137A, G, H, J ). Metasoma curved. Petiole on T1 with a mix of sculptures finely rugulate and punctate over most of the surface, virtually parallel-sided over most of length, but barely narrowing over distal 1/3, apex truncate (length 0.40, maximum width 0.22, minimum width 0.12), 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 0.22, length T2 0.22), edges of median area obscured by weak longitudinal stripes, median area broader than long (length 0.22, maximum width 0.32, minimum width 0.12); 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.

The body is distinctively curved.

Male.

Similar in coloration to female.

Etymology.

Ephantus Juma Muturi is a Kenyan-born entomologist. His research is focused on vector biology, primarily mosquito-microbe interactions and the development of ecofriendly strategies for mosquito control. Currently, he is a research entomologist at the Crop Bioprotection Research Unit, National Center for Agricultural Utilization Research, United States Department of Agriculture, Agricultural Research Service, Peoria, IL, USA.

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Yanayacu Road), during November 2007 at 2,100 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Undetermined species of Pyralidae feeding on Oreopanax sp. ( Araliaceae ). Caterpillar was collected in fourth instar.
