Coloration

( Fig. 12 A–M ). General body coloration dark brown except mandibles, scape and pedicel (both with lateral brown strip) yellow-brown; propleuron mostly brown with apex yellow; metasternum yellow; ventral edge of mesopleuron lighter than mesosoma coloration; labrum, maxillae, maxillary and labial palps, and tegulae yellow. Fore and middle legs yellow (in tarsomeres, yellow coloration intensity increasing from proximal to distal) except claws brown; hind legs yellow except a tiny brown dot at the apex of femora, tibiae with apex brown, all tarsomeres brown. Petiole on T1 dark brown with contours darkened and sublateral areas yellow; T2 with median and adjacent areas dark brown, and lateral ends yellow; T3 with an extended brown area which proximally coincides with width of dark area on T2, but distally narrow; T4 and beyond black. In lateral view, T1-3 completely yellow, T4-5 yellow, but dorsally brown; following tergites completely dark brown. S1-4 completely yellow, penultimate sternite with proximal half yellow and distal half brown; hypopygium completely brown.

Description.

Head ( Fig. 12 B–D ). Head rhomboid with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.25:0.08, 0.26:0.08, 0.25:0.08), distal antennal flagellomere longer than penultimate (0.14:0.05, 0.11:0.05), antenna longer than body (3.38, 2.53); antennal scrobes-frons sloped and forming a shelf. Face flat or nearly so, with dense and fine punctations, interspaces smooth 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 (0.09, 0.13). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 12F, G, J ). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation distinct throughout, and interspaces smooth. Scutellum triangular, apex sloped and fused with BS, scutellar punctation scattered throughout, 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 with a little, complete parallel carinae, dorsal ATS groove with carinae only proximally. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation with a smooth and shiny sloped transverse strip. 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 a groove with some sculpturing and distally smooth. Propodeum relatively polished without median longitudinal carina, proximal half weakly curved; 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 smooth, but both dorsal and ventral furrows with short parallel carinae. Propleuron with fine rugae and dorsally with a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep and with transverse lineate sculpture; epicnemial ridge elongated, more fusiform (tapering at both ends).

Legs ( Fig. 12A ). 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, 0.07). Hind coxa with punctation only on ventral surface, dorsal outer depression present, inner spur of hind tibia much longer than outer spur (0.35, 0.28), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.21, 0.15).

Wings ( Fig. 12L, M ). Fore wing with r vein curved; r and 2RS veins forming a weak, even curve at their junction and outer side of junction forming a slight stub; 2M vein straight; 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 and complete, but junction with 1-1A vein spectral. Hind wing with vannal lobe wide, subdistally evenly convex, subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 12H, I, K ). Metasoma laterally compressed. Petiole on T1 finely sculptured only laterally, evenly narrowing distally (length 0.40, maximum width 0.15, minimum width 0.10) 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 0.16, length T2 0.16), edges of median area polished and lateral grooves deep, median area as broad as long (length 0.16, maximum width 0.17, minimum width 0.08); T2 with scattered pubescence only distally. T3 longer than T2 (0.23, 0.16) and with scattered pubescence only distally. Pubescence on hypopygium dense.

Cocoon ( Fig. 12E ). Dark oval cocoon with silk fibers messy/disordered/fluffy.

Comments.

Some females have both the dorsal and the ventral furrows of pronotum lighter than mesosoma coloration. The coloration on T3 varies dorsally, some females with T3 mostly yellow, but with a central proximal yellow-brown spot that occupies 2/3 proximal and not touching the boundaries between T3-4. The lunules and PFM are lighter than mesosoma coloration.

Male

( Fig. 13 A–F ). Like other females, the T3 coloration varies dorsally, some males with T3 mostly yellow, but with a central proximal yellow-brown spot that occupies 2/3 proximal and not touching the boundaries between T3-4.

Etymology.

Andrew Henry Debevec is an American entomologist. As a graduate student at the UIUC, IL, USA, he was interested in Microgastrinae, mainly the genus Xanthomicrogaster . Now, he works as an IT specialist in the School of Integrative Biology at UIUC, IL, USA.

Distribution.

Parasitized caterpillars were collected in Ecuador, Napo, Yanayacu Biological Station (Stream trail), during September 2007, and August and November 2009 at 1,998 m, 2,006 m, 2,075 m, and 2,114 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is solitary.

Host.

Undetermined species of Pyralidae and Noctuidae feeding on Diplazium costale var. robustum ( Dryopteridaceae ). Caterpillars were collected in second and third instar.
