Diagnosis.

Vertex in lateral view pointed or nearly so ( Figs 146C , 147C ), scutellum in profile slightly convex, but on same plane as mesoscutum ( Figs 146G , 147H ), scutellar punctation distinct throughout ( Figs 146E , 147E, F ), anteroventral contour of mesopleuron straight/angulate or nearly so ( Figs 146A, G , 147A, H ), distal antennal flagellomere subequal in length with penultimate, propodeal spiracle without distal carina ( Fig. 147F ), fore wing with 2RS slightly convex, outer side of junction of r and 2RS veins not forming a stub ( Fig. 146J ), and lateral grooves delimiting the median area on T2 distally losing definition ( Fig. 146F, G ).

Coloration

( Fig. 146 A–K ). General body coloration brown-black except scape and pedicel yellow; first three-four proximal antennal flagellomeres dorsally lighter (yellow-brown) than ventrally (brown), remaining flagellomeres brown on both sides; labrum and mandible yellow/yellow-brown; glossa, maxillary and labial palps, and tegulae yellow. Eyes gray and ocelli silver. Fore and middle legs yellow except brown coxae and brown claws; hind legs yellow except brown-black coxae, femora distally and ventrally brown, distal half of tibiae brown and tarsomeres brown, although basitarsus proximally with a narrow yellow band. Petiole on T1 with two colorations: proximal 3/4 reddish/yellow-brown and distal 1/4 brown, contours darkened and sublateral areas yellow with some brown tint; T2 with median and adjacent areas brown, and lateral ends yellow; T3 broadly brown except lateral ends yellow, thus brown coloration from T2-3 looks like a large pyramid-shaped; T4 mostly brown, but corners proximally yellow; T5 and beyond completely brown; distally each tergum with a narrow whitish translucent band. In lateral view, T1-2 yellow; T3 yellow, but dorsodistal corner brown; T4 and beyond brown. S1-2 yellow; S3 yellow, but medially with a longitudinal brown band; S4 and beyond brown.

Description.

Head ( Fig. 146 A–D ). Head rhomboid with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.21:0.07, 0.19:0.07, 0.20:0.07), distal antennal flagellomere subequal in length with penultimate (0.11:0.06, 0.10:0.06), antenna longer than body (2.78, 2.47); antennal scrobes-frons shallow. Face flat or nearly so, with dense fine punctations, interspaces with microsculpture and longitudinal median carina present. Frons smooth. Temple wide, punctate 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 (0.09, 0.12). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 146A, E ). Mesosoma dorsoventrally convex. Mesoscutum 1/4 distal with a central dent, punctation distinct throughout, interspaces with microsculpture. Scutellum triangular, apex sloped and fused with BS, scutellar punctation distinct 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 a little, complete and parallel carinae; dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation smooth, shiny and nearly at the same level as mesoscutum (flat). Metanotum with BM wider than PFM (clearly differentiated); MPM circular 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 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 punctations throughout and dorsally with a carina. Metasternum flat or nearly so. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep with faintly transverse lineate sculpture; epicnemial ridge elongated more fusiform (tapering at both ends).

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 (0.12, 0.06). Hind coxa with punctation only on ventral surface and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.23, 0.16), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus as equal in length as fourth tarsomere (0.10, 0.10).

Wings ( Fig. 146J, K ). Fore wing with r vein curved; 2RS vein slightly convex to convex; r and 2RS veins forming a weak, even curve at their junction and outer side of junction not forming a 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, vein 2CUa absent and vein 2CUb spectral; vein 2 cu-a absent; vein 2-1A present only proximally as tubular vein; tubular vein 1 cu-a straight, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe narrow, subdistally straightened and subproximally straightened, and setae present only proximally.

Metasoma ( Fig. 146A, H, I ). Metasoma laterally compressed. Petiole on T1 finely sculptured only laterally, virtually parallel-sided over most of length, but narrowing over distal 1/3 (length 0.32, maximum width 0.18, minimum width 0.10), and with scattered pubescence concentrated in the first distal third. Lateral grooves delimiting the median area on T2 distally losing definition (length median area 0.10, length T2 0.15), edges of median area polished and lateral grooves deep, median area broader than long (length 0.10, maximum width 0.22, minimum width 0.08); T2 with scattered pubescence only distally. T3 longer than T2 (0.20, 0.15) and with scattered pubescence throughout. Pubescence on hypopygium dense.

Cocoons. White or brown oval cocoons with ordered silk fibers but covered by a net. Cordwood cocoons adhered to the leaf substrate.

Comments.

In some females, the coloration on S1-2 is completely light yellow-brown, S3 and beyond, including the hypopygium are completely brown. The median longitudinal carina on the face is short. The body is short and stout.

Male

( Fig. 147 A–I ). Coloration and body shape similar to female. The fore telotarsus with ventral margin even instead of excavated and seta right instead of curved.

Etymology.

Mallory Van Wyngaarden worked from 2010 to 2013 as a data manager in the Barcode of Life Data Systems. Currently, she works at the Institute of Infection, Immunity and Inflammation, University of Glasgow, United Kingdom.

Distribution.

The parasitized caterpillars were collected in Costa Rica, ACG, Sector Mundo Nuevo ( Portón Rivas and Vado Zanja Tapada), during August 2005 and November 2007 at 550 m and 570 m in dry-rain intergrade forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Rifargia elgiva Schaus ( Notodontidae : Heterocampinae) feeding on Styrax argenteus ( Styracaceae ). Caterpillars were collected in fourth instar.
