Type material.

Holotype: ECUADOR • 1♀; EC-12625, YY-A207; Napo, Yanayacu Biological Station, Ruben trail, Plot 186; cloud forest; 2,105 m, - 0.6, -77.883333; 24.ii.2006; María de los Ángeles Simbaña leg.; caterpillar collected in first instar; cocoons formed on 14.iii.2006; adult parasitoids emerged on 09.iv.2006; ( PUCE).

Diagnosis.

Distal antennal flagellomere subequal in length with penultimate, posterior ocelar line broader than ocular ocelar line ( Fig. 22D ), mesoscutum punctation proximally distinct, but distally absent/dispersed ( Fig. 22F ), lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 ( Fig. 22H, I ), axillary trough of metanotum proximally with semircular/undulate carina, distally smooth ( Fig. 22G ), precoxal groove shallow, but visible ( Fig. 22A, J ), anteroventral contour of mesopleuron straight/angulate or nearly so ( Fig. 22A, J ), edges of median area on T2 polished and followed by a deep groove ( Fig. 22H, I ), and fore wing with r vein curved, outer side of junction of r and 2RS veins forming a slight stub ( Fig. 22L ).

Coloration

( Fig. 22 A–M ). General body coloration black except labrum, mandibles, and tegulae yellow-brown; glossa, maxillary and labial palps yellow. Eyes gray/black and ocelli whitish/reddish. Fore and middle legs yellow or light yellow-brown, except tibiae with a dorsal narrow brown strip from top to bottom, middle tarsomeres light brown, claws brown; hind legs yellow except a tiny brown area in both ends of coxae, tibiae with a dorsal narrow brown strip from top to bottom, and tarsi and claws brown. Petiole on T1 black and sublateral areas yellow; T2 with median area black-brown and lateral ends brown; T3 and beyond black-brown; distally each tergum with a narrow yellowish transparent band. In lateral view, T1-2 completely yellow; T3 and beyond yellow, but dorsally brown, the extent of brown area increasing from proximal to distal. S1-3 completely yellow; S4 yellow-brown; penultimate sternum and hypopygium completely brown.

Description.

Head ( Fig. 22 A–D ). Head triangular with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.28:0.10, 0.29:0.10, 0.31:0.10), distal antennal flagellomere subequal in length with penultimate (0.14:0.06, 0.14:0.06), antenna longer than body (4.04, 2.99); antennal scrobes-frons shallow. Face with lateral depression with scattered finely punctate, interspaces smooth, and longitudinal median carina present. Frons punctate. 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 broader than OOL (0.14, 0.11). Malar suture present. Median area between lateral ocelli without depression. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 22A, F–H, J ). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation proximally distinct, but distally absent/dispersed, and interspaces wavy/lacunose. Scutellum triangular, apex sloped and fused with BS, scutellar punctation scattered throughout, in profile scutellum slightly convex, but 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 carinae only proximally. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation smooth, shiny and depressed centrally. Metanotum with BM wider than PFM (clearly differentiated); MPM semicircular without median longitudinal carina; AFM without setiferous lobes and not as well delineated as PFM; PFM thick and smooth; ATM proximally with semircular/undulate carina and distally smooth. Propodeum relatively polished without median longitudinal carina, proximal half straight or nearly so; 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 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 flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; 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). Hind coxa with punctation only on ventral surface, dorsal outer depression absent, entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.14, 0.09).

Wings ( Fig. 22L, M ). 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 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 curved, complete, but junction with 1-1A vein spectral. Hind wing with vannal lobe very narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 22A, H, I, K ). Metasoma laterally compressed. Petiole on T1 completely smooth and polished, with faint, satin-like sheen, virtually parallel-sided over most of length, but narrowing over distal 1/3 (length 0.42, maximum width 0.20, minimum width 0.11), 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 0.12, length T2 0.12), edges of median area polished, median area broader than long (length 0.12, maximum width 0.20, minimum width 0.08); T2 with scattered pubescence throughout. T3 longer than T2 (0.25, 0.12) and with scattered pubescence throughout.

Cocoon ( Fig. 22E ). White oval cocoon with silk fibers messy/disordered/fluffy.

Comments.

The inner spur in hind tibiae is missing. Length of the inner hind tibial spur is 0.24 mm, the outer spur is glued to pointed card, so it is difficult to see and measured.

Female.
