Type material.

Holotype: ECUADOR • 1♀; EC-12001, YY-A202; Napo, Yanayacu Biological Station, Río Arenillas, Plot 174; cloud forest; 1,973 m; - 0.566667, -77.866667; 06.ii.2006; María de los Angeles Simbaña leg.; caterpillar collected in third instar; cocoon formed on 28.ii.2006; adult parasitoid emerged on 21.iii.2006; ( PUCE).

Diagnosis.

Medioanterior pit of metanotum semicircular without median longitudinal carina ( Fig. 177E, F ), vertex in dorsal view narrow ( Fig. 177D ), scutellar punctation scattered throughout ( Fig. 177E, F ), dorsal furrow of pronotum with a well-defined smooth band ( Fig. 177A, C, I ), dorsal carina delimiting a dorsal furrow on propleuron present ( Fig. 157C ), anterior furrow of metanotum without setiferous lobes ( Fig. 177E, F ), axillary trough of scutellum with sculpture ( Fig. 177E, F ), lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2, edges of median area polished and followed by a deep groove ( Fig. 177G, H ), propodeum without median longitudinal carina ( Fig. 177F ), anteroventral contour of mesopleuron convex ( Fig. 177A, I ), and fore wing with r vein curved, outer side of junction of r and 2RS veins forming a slight stub ( Fig. 177K ).

Coloration

( Fig. 177 A–L ). General body coloration satin black except apex labrum and maxillary yellow-brown; clypeus brown/reddish; glossa, maxillary and labial palps, and tegulae light brown; pedicel with apex yellow-reddish; scape and all antennal flagellomeres (on both sides) dark brown. Eyes and ocelli silver. Fore and middle legs dark yellow except claws brown; hind legs yellow-brown except coxae black distally brown/reddish, femora dorso-distal brown, tibiae brown, and tarsomeres brown. Petiole on T1 with two colorations: proximal half brown-reddish and distal half black, contours darkened mainly in proximal half, and sublateral areas yellow; T2 with median area brown, adjacent area very narrow, thus contours of median area looks darker, and lateral ends yellow; T3 with a brown area, proximally that dark area coinciding with width of median area of T2 and distally almost reaching the edge of T3; T4 and beyond completely brown; distally each tergum with a narrow yellow transparent band. In lateral view, T1-3 completely yellow; T4-5 yellow, but dorsally brown; T5 and beyond completely brown. S1-3 yellow; S4-5 yellow and medially with a brown area; remaining sterna brown.

Description.

Head ( Fig. 177 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.29:0.09, 0.30:0.09, 0.29:0.09), distal antennal flagellomere longer than penultimate (0.18:0.08, 0.15:0.08), antenna longer than body (4.45, 3.58); antennal scrobes-frons sloped and forming a shelf. Face flat or nearly so, punctate-lacunose, interspaces wavy 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 (0.12, 0.14). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally narrow.

Mesosoma ( Fig. 177A, E, F, I ). Mesosoma dorsoventrally convex. Mesoscutum with narrow grooves laterally, punctation distinct proximally with polished area distally, interspaces smooth. Scutellum triangular, apex sloped and fused with BS, but not in the same plane, scutellar punctation scattered 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 carinae only proximally. Transscutal articulation with small and homogeneous foveae, area just behind transscutal articulation smooth, shiny and sloped. Metanotum with BM convex; MPM semicircular 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 a groove with some sculpturing and distally smooth. Propodeum without median longitudinal carina, proximal half curved with medium-sized sculpture and distal half relatively polished; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle distally framed by a short concave 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 with 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 entire without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.15, 0.08). Half dorsal hind coxa with scattered punctation and half ventral with dense punctation, dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.44, 0.35), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.20, 0.16).

Wings ( Fig. 177K, 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 proximal half smooth; veins 2CUa and 2CUb completely spectral; vein 2 cu-a present as spectral vein, sometimes difficult to see; vein 2-1A tubular throughout; tubular vein 1 cu-a straight and complete, but junction with 1-1A vein spectral. Hind wing with vannal lobe, subdistally and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 177G, H, J ). Metasoma cylindrical . Petiole on T1 finely sculptured distally, but only laterally, virtually parallel-sided over most of length, but narrowing over distal 1/3 (length 0.52, maximum width 0.23, minimum width 0.15), 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 0.17, length T2 0.17), edges of median area polished and lateral grooves deep, median area broader than long (length 0.17, maximum width 0.28, minimum width 0.12); T2 with scattered pubescence only distally. T3 longer than T2 (0.22, 0.17) and with scattered pubescence only distally.

Cocoons. Unknown.

Comments.

The ocelli are very close to each other ( Fig. 177D , the median ocellus diameter is 0.07 mm, the distance between the median ocellus and the posterior ocellus is 0.03 mm), the limit between the mesopleuron and the metasternum has a dent, and the hind coxa is stout ( Fig. 177A ).

Female.

Unknown.

Etymology.

Francisco (Pacho) Piñas Rubio is an Ecuadorian lepidopterologist who has dedicated his research to documenting the diversity of this insect group in Ecuador.

Distribution.

Biology.

The lifestyle of this parasitoid species is solitary.

Host.

Undetermined species of Noctuidae feeding on Acalypha sp. ( Euphorbiaceae ). Caterpillar was collected in third instar.
