Petiole on T1 black with contours slightly darkened and sublateral areas yellow-brown; T2 with median area black, wide adjacent area brown forming a irregular shape, and lateral ends yellow-brown; T3 black, but proximal corners yellow-brown with diagonal inner edges; T4 and beyond completely black-brown; distally each tergum with a narrow whitish transparent band. In lateral view, T1-2 completely yellow-brown; T3 proximal half yellow-brown and distal half brown; T4 and beyond completely brown. S1-3 yellow, but medial brown; S4 and beyond completely brown.

Description.

Head ( Fig. 18 B–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.17:0.06, 20.18:0.06, 0.20:0.06), distal antennal flagellomere longer than penultimate (0.12:0.03, 0.10:0.03), antenna longer than body (2.68, 2.22); antennal scrobes-frons shallow. Face with dense fine punctations, interspaces with microsculpture, face with depression only laterally and longitudinal median carina present. Frons punctate. Temple wide, punctate and interspaces wavy. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.10, 0.12). Malar suture present. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 18E, F, I ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct proximally, but absent/dispersed distally, and interspaces with microsculpture. Scutellum short and broad, apex sloped and fused with BS, scutellar punctation distinct throughout, in profile scutellum slightly convex, but on same plane as mesoscutum, phragma of the scutellum partially exposed; BS not overlapping the MPM; ATS demilune with short stubs delineating the area; dorsal ATS groove smooth. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation smooth, shiny and nearly at the same level as mesoscutum (flat). Metanotum with BM wider than PFM (clearly differentiated); MPM circular without median longitudinal carina; AFM with a small lobe and not as well delineated as PFM; PFM thick and smooth; ATM proximally with semircular/undulate carina and distally smooth. Propodeum without median longitudinal carina, proximal half weakly curved with medium-sized sculpture and distal half with a shallow dent at each side of nucha; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle distally framed by faintly concave/wavy carina; nucha surrounded by very short radiating carinae. Pronotum with a distinct dorsal furrow, dorsally with a narrow band; central area of pronotum smooth, but both dorsal and ventral furrows with short parallel carinae. Propleuron with fine rugae and dorsally without a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove shallow, but visible and with faintly lineate sculpture; epicnemial ridge elongated more fusiform (tapering at both ends).

Legs ( Fig. 18A ). Ventral margin of fore telotarsus entire, but with a tiny curved seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.12, 0.10). Hind coxa with punctation only on ventral surface, dorsal outer depression absent. Inner spur of hind tibia much longer than outer spur (0.20, 0.12), entire surface of hind tibia with dende strong spines clearly differentiated by color and length. Hind telotarsus as equal as fourth tarsomere (0.10, 0.11).

Wings ( Fig. 18K, L ). Fore wing with r vein curved; 2RS vein slightly convex to convex; r and 2RS veins forming a weak, even curve at their junction and outer side of junction not forming a stub; 2M vein slightly curved/swollen; distally fore wing [where spectral veins are] with microtrichiae almost homogeneously distributed as 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 absent; vein 2-1A proximally tubular and distally spectral, although sometimes difficult to see; 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. 18G, H, J ). Metasoma cylindrical . Petiole on T1 finely sculptured on 3/4 proximal, parallel-sided in proximal half and then narrowing (length 0.30, maximum width 0.14, minimum width 0.08) and pubescence on distal half. Lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 (length median area 0.15, length T2 0.15), edges of median area obscured by weak longitudinal stripes, median area broader than long (length 0.15, maximum width 0.18, minimum width 0.07); T2 with scattered pubescence throughout. T3 longer than T2 (0.20, 0.15) and with scattered pubescence throughout. Pubescence on hypopygium dense.

Cocoons. Unknown.

Comments.

The sculpture on the body is rough. The junction between the placodes on flagellomeres is darker than flagellomere itself. On the face, the median longitudinal carina extends from the scrobes to the clypeus. The median area on the propodeum has a transversal fine rugae. Some females from the same sample have both dorsal and ventral furrows of pronotum and distally the propleuron with reddish/brown tints.

Male

( Fig. 19 A–G ). Coloration similar to that of female.

Etymology.

Andrew (Andy) Suarez’s research is focused upon knowing the causes and consequences of biological invasions, mainly ants, and how polymorphism and complex societies contribute to their ecological success. Currently, he is head of Department of Animal Biology at UIUC, USA.

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Baeza Granja Integral), during May 2006 at 1,896 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Bertholdia partita Rawlins ( Erebidae : Arctiinae) feeding on Renealmia fragilis ( Zingiberaceae ). Caterpillar was collected in second instar. In Ecuador, B. partita has been reported as host for three families of Hymenoptera : two groups of Eulophidae , one group of Braconidae and one group of Ichneumonidae ; and one family of Diptera : Tachinidae .
