Paratypes. • 20 (5♀, 3♂) (12♀, 0 ♂); EC-5125, YY-A074; same data as for holotype; ( PUCE) .

Diagnosis.

Medioanterior pit of metanotum circular without median longitudinal carina and very partially covered by medioposterior band of scutellum ( Fig. 140F ), transscutal articulation with tiny homogeneous foveae without carina ( Fig. 140E ), inner margin of eyes diverging slightly at antennal sockets ( Fig. 140B ), median area on T2 broader than long, edges of median area on T2 obscured by weak longitudinal stripes ( Fig. 140G, H ), ventral margin of fore telotarsus entire without seta, anteroventral contour of mesopleuron straight/angulate ( Fig. 140A, I ), propleuron with fine punctations throughout, longitudinal median carina on face present ( Fig. 140B ), surface of metasternum convex, dorsal outer depression on hind coxa absent ( Fig. 140A, J ), and fore wing with r vein curved, outer side of junction of r and 2RS veins forming a stub ( Fig. 140K ).

Coloration

( Fig. 140 A–L ). General body coloration brown except scape and pedicel with apex yellow-brown; first four-five proximal antennal flagellomeres dorsally lighter (light brown) than ventrally (dark brown), remaining flagellomeres dark brown on both sides; labrum and mandibles yellow-brown; glossa, maxillary and labial palps, and tegulae yellow; pronotum, lunules, BS, AFM, and PFM with brown-red/reddish tints. Eyes gray and ocelli reddish (in preserved specimen). Fore and middle legs yellow except brown claws; hind legs yellow except black coxae with apex yellow/yellow-brown (coloration that is more extended ventrally), femora with a small brown area in the apex, distal half of tibiae brown and distally with a small brown band, and tarsomeres brown. Petiole on T1 with two colorations: distally brown and proximally brown-red/reddish, 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 ends; T4 and beyond brown; distally each tergum with a narrow yellowish translucent band. In lateral view, T1-3 completely yellow; T4 yellow, but distally with a brown band; T5 and beyond completely brown. S1-2 yellow; S3-4 proximal half yellow, distal half brown; penultimate sternum and hypopygium completely brown.

Description.

Head ( Fig. 140 A–D ). Head rectangular with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.22:0.06, 0.20:0.06, 0.20:0.06), distal antennal flagellomere longer than penultimate (0.13:0.05, 0.10:0.05), antenna longer than body (2.58, 2.48); antennal scrobes-frons sloped and forming a shelf. Face finely punctate-lacunose, interspaces wavy, distal half dented only laterally, 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 (0.07, 0.12). Malar suture absent or difficult to see. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 140A, E, F, I ). Mesosoma dorsoventrally convex. Mesoscutum distal half with a central dent, punctation distinct throughout, interspaces smooth. Scutellum triangular, apex sloped and fused with BS, but not in the same plane, scutellar punctation distinct peripherally, 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 smooth. Transscutal articulation with small and homogeneous foveae, area just behind transscutal articulation nearly at the same level as mesoscutum (flat) and with same kind of sculpture as mesoscutum. 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, smooth and with lateral ends rounded; ATM proximally with sculpture distally without a well delimited smooth area. Propodeum finely sculptured without median longitudinal carina, proximal half weakly curved with fine 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 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 and dorsal furrow smooth, but ventral furrow with short parallel carinae. Propleuron with fine punctations throughout and dorsally without a carina. Metasternum convex. 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 entire without seta, fore telotarsus proximally narrow and distally wide, and longer than fourth tarsomere (0.13, 0.06). Hind coxa finely punctate throughout, and dorsal outer depression absent. Inner spur of hind tibia longer than outer spur (0.21, 0.17), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.12, 0.13).

Wings ( Fig. 140K, L ). Fore wing with r vein curved; 2RS vein straight; 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; tubular vein 1 cu-a straight, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe very narrow, subdistally and subproximally straightened, and setae present proximally, but absent distally.

Metasoma ( Fig. 140A, E, F, I ). Metasoma laterally compressed. Petiole on T1, distal half with faint rugae only laterally, with virtually parallel-sided over most of length, but barely narrowing over distal 1/3, apex truncate (length 0.38, maximum width 0.19, minimum width 0.14), 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 0.16, length T2 0.16), edges of median area obscured by weak longitudinal stripes, median area broader than long (length 0.16, maximum width 0.20, minimum width 0.12); T2 with scattered pubescence throughout. T3 longer than T2 (0.21, 0.16) and with pubescence more notorious in distal half. Pubescence on hypopygium dense.

Cocoons. With “frill” around hosts body and attached to larval cuticle.

Male.

Similar coloration to female.

Etymology.

Kyle Parks is an American entomologist. As a graduate student at the UIUC, IL, USA, he was interested in Microgastrinae, mainly the genera Parapanteles and Clarkinella . Mason.

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station ( Yanayacu Forest ), during July 2005 at 2,359 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Undetermined species of Nymphalidae , food plant was not reported. Caterpillar was collected in second instar.
