Paratypes. • 7 (2♀, 4♂) (1♀, 0 ♂); EC-36028, YY-A061; same data as for holotype; ( PUCE) .

Diagnosis.

In lateral view, metasoma cylindrical ( Fig. 162A, J ), hind coxa punctate only on ventral surface ( Fig. 162A, J ), propodeum with a transverse discontinuous carina only present laterally ( Fig. 162F ), petiole on T1 virtually parallel-sided, but narrowing at apex ( Fig. 162G, H ), scutellar punctation indistinct throughout ( Fig. 162E, F ), edges of median area on T2 obscured by weak longitudinal stripes ( Fig. 162G ), dorsal outer depression on hind coxa present ( Fig. 162A, J ), and fore wing with r vein curved, outer side of junction of r and 2RS veins forming a slight stub ( Fig. 162K ).

Coloration

( Fig. 162 A–K ). General body coloration polished black except mandibles brown/reddish; glossa, maxillary and labial palps, and tegulae yellow; pedicel distally yellow-reddish; scape and all antennal flagellomeres (on both sides) dark brown/black. Eyes silver and ocelli yellowish. Fore and middle legs dark yellow, and claws brown, although tibiae and tarsomeres with brown tints; hind legs dark yellow except black coxae, femora dorsally with a tiny brown spot, tibiae distally brown and proximally with a narrow brown band, and tarsomeres brown. Petiole on T1 black and sublateral areas yellow-brown; T2 with median area black, wide adjacent area dark brown/black, limits of adjacent area with lateral ends not clearly defined; T3 and beyond completely dark brown/black; distally each tergum with a narrow whitish transparent band. In lateral view, T1 -– 2 yellow; T3 and beyond yellow, but dorsally brown, extent of brown area increasing from proximal to distal, so distal terga completely brown. S1-3 yellow; S4 and beyond brown.

Description.

Head ( Fig. 162 A–D ). Head rounded pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.22:0.08, 0.22:0.08, 0.23:0.08), distal antennal flagellomere longer than penultimate (0.14:0.06, 0.10:0.06), antenna longer than body (2.78, 2.48); antennal scrobes-frons sloped and forming a shelf. Face with dense fine punctations, distal half dented only laterally, interspaces with microsculpture and longitudinal median carina present. Frons smooth. Temple 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 shorter than OOL (0.08, 0.15). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 162A, E, F, I ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout, interspaces wavy/lacunose. Scutellum triangular, apex sloped and fused with BS, but not in the same plane, scutellar punctation indistinct throughout, in profile scutellum flat and on same plane as mesoscutum, phragma of the scutellum completely concealed; BS mostly overlapping the MPM; ATS demilune inner side with a row of foveae; 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 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 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 a short transverse carina; nucha surrounded by long radiating carinae. Pronotum with a distinct dorsal furrow, dorsally with a defined smooth band only proximally; central area of pronotum and dorsal furrow smooth, but ventral furrow with short parallel carinae. Propleuron finely sculptured only ventrally and dorsally without a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove smooth, shiny and shallow, but visible; epicnemial ridge convex, teardrop-shaped.

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 (0.15, 0.08). Hind coxa with punctation only on ventral surface, dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.35, 0.21), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.13, 0.13).

Wings ( Fig. 162K ). 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 a small smooth area; 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 straight and complete, but junction with 1-1A vein spectral. Hind wing with vannal lobe narrow, subdistally and subproximally straightened, and setae absent proximally, but scattered distally.

Metasoma ( Fig. 162A, G, H, J ). Metasoma cylindrical . Petiole on T1 with a mix of fine rugae and punctate sculpture over most of the surface, parallel-sided over most of length, but barely narrowing at apex, apex truncate (length 0.35, maximum width 0.20, minimum width 0.18), 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 0.15, length T2 0.15), edges of median area obscured by weak longitudinal stripes, median area broader than long (length 0.15, maximum width 0.23, minimum width 0.12); T2 with scattered pubescence only distally. T3 longer than T2 (0.22, 0.15) and with pubescence more notorious in distal half. Pubescence on hypopygium scattered.

Cocoons. Unknown.

Comments.

The antenna is curled. The median ocellus is very close to lateral ocelli ( Fig. 162D , diameter of median ocellus 0.07 mm, the distance between median and lateral ocellus is 0.02 mm); the propodeum with a transverse discontinuous carina only present laterally; distally the propodeum forming a wall ( Fig. 162F ); the pronotum is very deep, at different plane than mesopleuron ( Fig. 162A, I ); the body is stout. This species looks like Parapanteles because of petiole shape (parallel sides, Fig. 162G ) and distal half of propodeum (each lateral side with a deep dent, Fig. 162F ).

Male.

Similar in coloration to females.

Etymology.

Michelle (Poly Nator) Audrey Duennes’ research at UIUC, IL, USA, was focused on the phylogenetic relationships among a New World bumble bee species complex. Currently, she is assistant professor at St. Vincent College, Latrobe, PA, USA

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Yanayacu Road), during November 2008 at 2,100 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Undetermined species of Pantheidae feeding on Rubus sp. ( Rosaceae ). Caterpillar was collected in third instar.
