Diagnosis.
Fore telotarsus proximally narrow, distally wide, medioposterior band of scutellum mostly overlapping the medioanterior pit of metanotum ( Figs 163D View Figure 163 , 164C View Figure 164 ), petiole on T1 distally with lateral margins curved (convex), finely sculptured only laterally ( Figs 163E, H View Figure 163 , 164D View Figure 164 ), surface of metasternum flat or nearly so, precoxal groove deep with lineate sculpture ( Figs 163A, F View Figure 163 , 164A, B View Figure 164 ), fore wing with vein 1 cu-a curved, r vein curved, outer side of junction of r and 2RS veins not forming a stub ( Figs 163J View Figure 163 , 164F View Figure 164 ), dorsal outer depression on hind coxa present ( Figs 163A, G View Figure 163 , 164A View Figure 164 ), inner margin of eyes diverging slightly at antennal sockets, propodeum without median longitudinal carina ( Figs 163D View Figure 163 , 164C View Figure 164 ), and lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 ( Figs 163E, H View Figure 163 , 164D View Figure 164 ).
Coloration
( Fig. 163 A–K View Figure 163 ). General body coloration polished black except scape and pedicel yellow-brown with lateral brown band; last seven-eight distal antennal flagellomeres lighter (light brown) than remaining flagellomeres (dark brown); labrum and mandible yellow-brown; glossa, maxillary and labial palps, and tegulae yellow; both dorsal and ventral furrows of pronotum lighter than mesosoma coloration. Eyes gray and ocelli yellowish. Fore and middle legs yellow except middle coxae proximally with a small brown area, and claws brown; hind legs black except trochanters, trochantellus, distal 1/3 of tibiae yellow, and basitarsus proximally with a narrow yellow band. Petiole on T1 black, contours darkened and sublateral areas yellow; T2 with median and adjacent areas brown, adjacent area very narrow, and lateral ends yellow; T3 with a brown area, which width coinciding with the width of median area plus adjacent area on T2, thus brown coloration from T2 -– 3 looks like a large pyramid-shaped, and lateral ends yellow; T4 and beyond completely brown; distally each tergum with a narrow yellowish transparent band. In lateral view, T1-3 yellow; T4 and beyond brown. S1-3 yellow; S4 proximal half yellow, distal half brown; penultimate sternum and hypopygium brown.
Description.
Head ( Fig. 163A, B View Figure 163 ). Head rhomboid with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.16:0.05, 0.16:0.05, 0.17:0.05), distal antennal flagellomere longer than penultimate (0.10:0.05, 0.08:0.05), antenna longer than body (2.27, 20.02); 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 (0.09, 0.11). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide.
Mesosoma ( Fig. 163A, C, D, F View Figure 163 ). Mesosoma dorsoventrally convex. Mesoscutum proximally convex and distally flat, punctation distinct throughout, interspaces wavy/lacunose. Scutellum triangular, apex sloped and fused with BS, scutellar punctation distinct throughout, in profile scutellum flat and on same plane as mesoscutum, phragma of the scutellum partially exposed; BS mostly overlapping the MPM; ATS demilune with quite 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 with a smooth and shiny sloped transverse strip. Metanotum with BM wider than PFM (clearly differentiated); MPM semicircular and bisected by a median longitudinal carina; AFM with a small lobe 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 slightly rugose; distal edge of propodeum with a flange at each side and short 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 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 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 proximally narrow and distally wide, 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 (0.20, 0.14), 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, 0.09).
Wings ( Fig. 163J, K View Figure 163 ). Fore wing with r vein 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 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 very narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.
Metasoma ( Fig. 163A, E, G–I View Figure 163 ). Metasoma laterally compressed. Petiole on T1 finely sculptured only laterally, virtually parallel-sided over most of length, but narrowing over distal 1/3 (length 0.25, maximum width 0.14, minimum width 0.10), and with scattered pubescence on distal half only laterally. 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 mm, maximum width 0.18, minimum width 0.07); T2 with scattered pubescence only distally. T3 longer than T2 (0.17, 0.12) and with scattered pubescence only distally. Pubescence on hypopygium scattered.
Cocoons ( Fig. 4F View Figure 4 ). Brown oval cocoons with evenly smooth silk fibers. Cocoons adhered to the larval cuticle or to the leaf substrate.
Male
( Fig. 164 A–G View Figure 164 ). Similar in coloration and shape to female.
Etymology.
Michael (Mike) Williams Gates is interested in morphology, natural history, phylogeny, systematics, and taxonomy of Chalcidoidea ( Hymenoptera ). He works at the Smithsonian Institution, Washington, DC., USA.
Distribution.
The parasitized caterpillars were collected in Costa Rica, ACG, Sector Cacao (Cuesta Caimito and Quebrada Otilio), during June 2005 and July 2006 at 550 m and 640 m in cloud forest.
Biology.
The lifestyle of this parasitoid species is gregarious.
Host.
Pero sp. Herrich-Schäffer ( Geometridae : Ennominae) ( Fig. 4F View Figure 4 ) feeding on Cyathula achyranthoides ( Amaranthaceae ) and undetermined species of plant. Caterpillars were collected in fourth and fifth instar.
