Coloration

( Fig. 195 A–L ). General body coloration black except scape and pedicel yellow-brown and outer edges both with a lateral brown band; first five-six proximal antennal flagellomeres dorsally lighter (light brown) than ventrally (dark brown), remaining flagellomeres dark brown; labrum, mandibles, and tegulae yellow-brown; glossa, maxillary and labial palps ivory/pale yellow. Eyes and ocelli silver. Fore and middle legs yellow except light brown coxae and claws brown; hind legs yellow except black coxae only distally yellow-brown (coloration is more extensive on the inner side), femora yellow-brown/brown only distally yellow, 2/3 distal of tibiae and tarsomeres brown, although proximally basitarsus with a small yellow band. Petiole on T1 brown, but proximal half lighter than distal half, contours darkened and sublateral areas yellow-brown; T2 with median and adjacent areas brown together forming a rectangle-shaped area, and lateral ends yellow-brown; T3 medially brown forming a dark area coinciding with the width of median and adjacent areas of T2, and lateral ends yellow-brown; T4 and beyond brown; distally each tergum with a narrow hyaline band. In lateral view, T1-3 yellow; T4 and beyond brown. S1-3 yellow; S4 yellow, but medially brown; penultimate sternum and hypopygium brown.

Description.

Head ( Fig. 195 A–D ). Head rounded with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.15:0.07, 0.16:0.07, 0.16:0.070), distal antennal flagellomere longer than penultimate (0.11:0.04, 0.08:0.04), antenna longer than body (2.46, 2.22); antennal scrobes-frons shallow. Face convex with dense 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 (0.95, 0.11). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 195A, F, G, J ). Mesosoma dorsoventrally convex. Mesoscutum distal half with a central dent, punctation distinct throughout, interspaces smooth. Scutellum triangular, apex sloped and fused with BS, 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 with short stubs delineating the area; dorsal ATS groove smooth. Transscutal articulation with large and heterogeneous foveae, area just behind transscutal articulation smooth, shiny and depressed centrally. 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 with a shallow dent at each side of nucha; 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 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 with transverse lineate sculpture; epicnemial ridge convex, teardrop-shaped.

Legs. Ventral margin of fore telotarsus excavated with conspicuous curved seta over this excavation, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.11, 0.06). Hind coxa with punctation only on ventral surface, dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.21, 0.12), entire surface of hind tibia with dense strong spines clearly differentiated by color and length. Hind telotarsus longer than fourth tarsomere (0.12, 0.10).

Wings ( Fig. 195L ). 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 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 curved, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 195A, E, H, I, K ). Metasoma laterally compressed. Petiole on T1 finely sculptured only laterally, virtually parallel-sided over most of length, but narrowing over distal 1/3 (length 0.28, maximum width 0.15, minimum width 0.09), 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 0.12, length T2 0.12), edges of median area polished and lateral grooves deep, median area broader than long (length 0.12, maximum width 0.17, minimum width 0.06); T2 with scattered pubescence only distally. T3 longer than T2 (0.19, 0.12) and with scattered pubescence only distally. Pubescence on hypopygium scattered.

Cocoons. Characteristics unknown. Cocoons adhered to the larval cuticle.

Comments.

The body is elongate and slim ( Fig. 195A ).

Male

( Fig. 196 A–L ). Similar in coloration and shape to female.

Etymology.

Roy R. Snelling (30 September 1934 - 21 April 2008) was an internationally renowned American entomologist who studied Hymenoptera , mainly ants, wasps, and bees. He dedicated his professional life to making insect biodiversity better known and appreciated.

Distribution.

The parasitized caterpillar was collected in Costa Rica, ACG, Sector Nuevo Mundo (Camino Pozo Dos), during November 2008 at 728 m in dry-rain intergrade forest.

Biology.

The lifestyle of this parasitoid species is gregarious.

Host.

Undetermined species of Geometridae feeding on Bunchosia polystachia ( Malpighiaceae ). Caterpillar was collected in fifth instar.
